Chiropractic was founded in 1895 by ], based on his assertion that 95% of all health problems could be prevented or treated using adjustments of the spine (]s), and 5% by adjustment of other joints, to correct what he termed ]s. He, and later his son ], proposed that subluxations were misaligned vertebrae which caused nerve compression that interfered with the transmission of what he named ]. This interference interrupted the proper flow of Innate Intelligence from "above, down, inside, and out" to the organ to which it traveled. As a result, the human body would experience "dis-ease" or disharmony which would result in loss of health.

== Origins of Chiropractic and the concept of subluxation ==

{{main|Vertebral subluxation}}
DD Palmer, using a ] approach, imbued the term ] with a ] and ] meaning. He held that a malposition of spinal ]s, which protect the spinal cord and nerve roots, interfered with the transmission of nerve impulses. Because half of the nervous system is sensory and the other half motor (control), he postulated that living things had an ], a kind of "spiritual energy" or ] that received the sensory information from the various parts of the body and made a decision as to what the motor nerves should convey. DD Palmer claimed that subluxations interfered with this innate intelligence, and that by fixing them, all diseases could be treated.<ref>Palmer D.D., The Science, Art and Philosophy of Chiropractic. Portland, Oregon: Portland Printing House Company, 1910.</ref> He qualified this by noting that knowledge of Innate Intelligence was not essential to the competent practice of chiropractic.<ref name ="Forgotten Theories">Keating J (1995), D.D. Palmer's Forgotten Theories of Chiropractic, </ref>
The idea that all diseases were the result of a subluxation was in line with the common thinking of the day; that there was one cause for disease. The vitalistic concepts implied an intelligent governing entity that was readily perceived as spiritual constructs by many both inside and outside the profession. Chiropractors used these metaphorical concepts to rationalize their thinking about the body’s self-healing capacity.<ref name="Chiro Beliefs"/> In 1998, Lon Morgan DC, a reform chiropractor, wrote that: "Innate Intelligence clearly has its origins in borrowed mystical and occult practices of a bygone era. It remains untestable and unverifiable and has an unacceptably high penalty/benefit ratio for the chiropractic profession. The chiropractic concept of Innate Intelligence is an anachronistic holdover from a time when insufficient scientific understanding existed to explain human physiological processes. It is clearly religious in nature and must be considered harmful to normal scientific activity."<ref name="Morgan">Morgan L (1998) Innate intelligence: its origins and problems ''J Can Chir Ass'' 42:35-41 </ref>


Meridel I. Gatterman DC, educator and writer observed:
:"The word subluxation has been ... embodied with a multitude of meaning by chiropractors during the past one hundred years. To some it has become the holy word; to others, an albatross to be discarded ... to add to the confusion, more than 100 synonyms for subluxation have been used. Why then do we persist in using the term when it has become so overburdened with clinical, political, and philosophical ... significance ... that the concept that once helped to hold a young profession together now divides it and keeps it quarrelling over basic semantics? The obvious answer is: The concept of subluxation is central to chiropractic."<ref>Gatterman MI. Foundations of the Chiropractic
Subluxation. Baltimore: Williams and Wilkins, 1988:6. </ref>


Improvement of health status
Debate about the need to remove the concept of subluxation from the chiropractic paradigm has been ongoing since the mid 1960s. While straights hold firmly to the term and its vitalistic construct, reformers suggest that the mechanistic model will allow chiropractic to better integrate into mainstream medicine without making claims inherent in the term. Anthony Rosner PhD, director of education and research at the Foundation for Chiropractic Education and Research (FCER) considered subluxation and the concept of ]. He suggests "there is no obvious reason to discard the concept of subluxation, while at the same time maintaining that it is not a rigid entity, but rather an important model and concept; a work in progress that undoubtedly will undergo extensive modification as our concepts of light or psychoanalysis have evolved over half a century."<ref name="Anthony Rosner">Rosner A (2006) , ''Dynamic Chiropractic'' Aug 2006</ref>
| style="text-align:center;" | Universal intelligence


Despite the term's vitalistic roots, chiropractic today may still use the term Innate Intelligence; however, it has taken on a less metaphysical meaning. Innate Intelligence today is used to describe the self-healing power of the body. Thus, a modern chiropractic view is that by removing the restrictions caused by subluxation, the chiropractor is improving the body's own potential for self-healing.<ref>Nelson CF, Lawrence DJ, Triano JJ, Bronfort G, Perle SM, Metz RD, Hegetschweiler K, La Brot T.

Innate intelligence
== Chiropractic’s approach to healthcare ==


According to Robert Mootz ] and Reed Phillips ], ], although chiropractic has much in common with other health professions, its philosophical approach distinguishes it from modern medicine. Chiropractic philosophy involves what has been described as a "contextual, naturopathic approach" to health care.<ref>Black D (1990)''Inner Wisdom: The Challenge of Contextual Healing''. Springville, UT: Tapestry Press</ref> The traditional, "allopathic" or "medical" model considers disease as generally the result of some external influence, such as a toxin, a parasite, an allergen, or an infectious agent: the solution is to counter the perceived environmental factor (e.g., using an antibiotic for a bacterial infection). By contrast, the ''naturopathic'' approach considers that lowered "host resistance" is necessary for disease to occur, so the appropriate solution is to direct treatment to strengthen the host, regardless of the environment. In contemporary clinical practice, one can find elements of both naturopathic and allopathic philosophy among all types of providers.<ref name="Chiro Beliefs">AHCPR Chapter II </ref> The degree to which a practitioner emphasizes different tenets of these philosophies is one factor that determines the manner in which they practice.

The Chiropractic approach to healthcare stresses the importance of prevention. Former president of National College of Chiropractic, Joseph Janse DC (1909-1985) explains:
:"Unless pathology is demonstrable under the microscope, as in the laboratory or by roentgenograms, to them it does not exist. For years the progressive minds in chiropractic have pointed out this deficiency. With emphasis they have maintained the fact that prevention is so much more effective than attempts at a cure. They pioneered the all-important principle that effective eradication of disease is accomplished only when it is in its functional (beginning) phase rather than its organic (terminal) stage. It has been their contention that in general the doctor, the therapist and the clinician have failed to realize exactly what is meant by disease processes, and have been satisfied to consider damaged organs as disease, and to think in terms of sick organs and not in terms of sick people. In other words, we have failed to contrast disease with health, and to trace the gradual deteriorization along the downward path, believing almost that mild departures from the physiological normal were of little consequence, until they were replaced by pathological changes..."

''Straight'' chiropractors adhere to the philosophical principles set forth by D.{{nbsp}}D. and B.{{nbsp}}J. Palmer, and retain metaphysical definitions and vitalistic qualities.<ref name=History-Primer /> Straight chiropractors believe that vertebral subluxation leads to interference with an "innate intelligence" exerted via the human nervous system and is a primary underlying risk factor for many diseases.<ref name=History-Primer /> Straights view the medical diagnosis of patient complaints, which they consider to be the "secondary effects" of subluxations, to be unnecessary for chiropractic treatment.<ref name=History-Primer /> Thus, straight chiropractors are concerned primarily with the detection and correction of vertebral subluxation via adjustment and do not "mix" other types of therapies into their practice style.<ref name=History-Primer /> Their philosophy and explanations are metaphysical in nature and they prefer to use traditional chiropractic lexicon terminology such as "perform spinal analysis", "detect subluxation", "correct with adjustment".<ref name=Kaptchuk-Eisenberg /> They prefer to remain separate and distinct from mainstream health care.<ref name=Kaptchuk-Eisenberg /> Although considered the minority group, "they have been able to transform their status as purists and heirs of the lineage into influence dramatically out of proportion to their numbers."<ref name=Kaptchuk-Eisenberg />
=== Medicine vs. chiropractic ===


''Mixer'' chiropractors "mix" diagnostic and treatment approaches from chiropractic, medical or osteopathic viewpoints and make up the majority of chiropractors.<ref name=Kaptchuk-Eisenberg /> Unlike straight chiropractors, mixers believe subluxation is one of many causes of disease, and hence they tend to be open to mainstream medicine.<ref name=Kaptchuk-Eisenberg/> Many of them incorporate mainstream medical diagnostics and employ conventional treatments including techniques of ] such as exercise, ], ], ]s, ], ], and ].<ref name=Kaptchuk-Eisenberg /> Some mixers also use techniques from alternative medicine, including ], ], ], ], and ].<ref name=Kaptchuk-Eisenberg />
In September 1899, a medical doctor in Davenport, IA, named Heinrich Matthey started a campaign against drugless healers in Iowa. DD Palmer, whose school had just graduated its 7th student, insisted that his techniques did not need the same courses or license as medical doctors, as his graduates did not prescribe drugs or evaluate blood or urine. However, in 1906, Palmer was convicted for practicing medicine without a license. He chose to turn over his interests in the PSC to his son, BJ and wife, Mabel.


Although mixers are the majority group, many of them retain belief in vertebral subluxation as shown in a 2003 survey of 1,100 North American chiropractors, which found that 88 percent wanted to retain the term "vertebral subluxation complex", and that when asked to estimate the percent of disorders of internal organs that subluxation significantly contributes to, the mean response was 62 percent.<ref name=McDonald /> A 2008 survey of 6,000 American chiropractors demonstrated that most chiropractors seem to believe that a subluxation-based clinical approach may be of limited utility for addressing ]s, and greatly favored non-subluxation-based clinical approaches for such conditions.<ref name=Smith-Carber /> The same survey showed that most chiropractors generally believed that the majority of their clinical approach for addressing musculoskeletal/biomechanical disorders such as back pain was based on subluxation.<ref name=Smith-Carber>{{cite journal|journal=Journal of Chiropractic Humanities|year=2008|volume=15|pages=19–26|title=Survey of US Chiropractor Attitudes and Behaviors about Subluxation|vauthors=Smith M, Carber LA|url=http://archive.journalchirohumanities.com/Vol%2015/JChiroprHumanit2008v15-19-26.pdf|archive-url=https://web.archive.org/web/20120425234244/http://archive.journalchirohumanities.com/Vol%2015/JChiroprHumanit2008v15-19-26.pdf|archive-date=2012-04-25|doi=10.1016/s1556-3499(13)60166-7}}</ref> Chiropractors often offer conventional therapies such as physical therapy and lifestyle counseling, and it may for the lay person be difficult to distinguish the unscientific from the scientific.<ref name=Benedetti2002>{{Cite book|url=https://books.google.com/books?id=zHxockt9CWQC|title=Spin Doctors: The Chiropractic Industry Under Examination|last1=Benedetti|first1=Paul|last2=MacPhail|first2=Wayne|date=2002-01-01|publisher=Dundurn|isbn=978-1-55002-406-7|language=en|page=18}}</ref>

Palmer repudiated his earlier theory that vertebral subluxations caused pinched nerves in the intervertebral spaces in favor of subluxations causing altered nerve vibration, either too tense or too slack, affecting the tone (health) of the end organ.<ref name=Keating1995 /> He qualified this by noting that knowledge of innate intelligence was not essential to the competent practice of chiropractic.<ref name=Keating1995>{{cite web|url=http://chiro.org/Plus/History/Persons/PalmerDD/PalmerDD's_Forgotten_Theories1995.pdf |archive-url=https://web.archive.org/web/20070710071140/http://www.chiro.org/Plus/History/Persons/PalmerDD/PalmerDD's_Forgotten_Theories1995.pdf |archive-date=2007-07-10 |url-status=live|title= D.

Palmer, and was instrumental in providing the legal basis of differentiating chiropractic from conventional medicine. In 1910, D. D. Palmer theorized that the nervous system controlled health:
State laws to regulate and protect chiropractic practice were eventually introduced in all fifty states in the US, but it was a hard-fought struggle. Medical Examining Boards worked to keep all healthcare practices under their legal control, but an internal struggle among DCs on how to structure the laws significantly complicated the process. Initially, the UCA, led by BJ Palmer and armed with his philosophy, opposed state licensure altogether. Palmer feared that such regulation would lead to allopathic control of the profession.<ref name="Chiro Educ">Phillips R (1998), , Dynamic Chiropractic</ref> The UCA eventually caved in, but BJ remained strong in the opinion that examining boards should be composed exclusively of chiropractors (not those who mixed chiropractic with other remedies). Mixers campaigned to increase education standards equivalent to medical schools while Palmer resisted any increase in standards.

In 1975, the ] brought chiropractors, osteopaths, medical doctors and ] scientists together in a conference on spinal ] to develop strategies to study the effects of spinal ]. In 1978, the ''Journal of Manipulative & Physiological Therapeutics'' (JMPT) was launched, and in 1981 it was included in the National Library of Medicine's ''Index Medicus''.<ref name="Faulty Logic">Keating J </ref> Joseph Keating dates the birth of chiropractic as a science to a 1983 commentary in the JMPT entitled "Notes from the (chiropractic college) underground" in which Kenneth F. DeBoer, then an instructor in basic science at Palmer College in Iowa, revealed the power of a scholarly journal (JMPT) to empower faculty at the chiropractic schools. DeBoer's opinion piece demonstrated the faculty's authority to challenge the status quo, to publicly address relevant, albeit sensitive, issues related to research, training and skepticism at chiropractic colleges, and to produce "cultural change" within the chiropractic schools so as to increase research and professional standards. It was a rallying call for chiropractic scientists and scholars.<ref name="Faulty Logic"/>
Vertebral subluxation, a core concept of traditional chiropractic, remains unsubstantiated and largely untested, and a debate about whether to keep it in the chiropractic paradigm has been ongoing for decades.<ref name=Keating-subluxation /> In general, critics of traditional subluxation-based chiropractic (including chiropractors) are skeptical of its clinical value, ] beliefs and metaphysical approach.

<!-- **Move to a separate article? Summarize? Definitely need source referencing **
Under the direciton of Dr.Rob Francis, Dean of Clincal Sciences at TCC, the full momentum swinging chiropractic into the orhtodox health care delivery system was pioneered through Texas Chiropractic College (TCC) which led the way for chiropractic's entrance into mainstream medical acceptance of chiropractors practicinig in the orthodox health care delivery system through the development of the first hospital rotation program for chiropractic students.
The first hospital rotation for chiropractic interns and the first certification course in Manipulation Under Anesthesia (MUA) for chiropractors was developed in the 1980’s, by Dr. Rob Francis while Dean of Clinical Sciences at Texas Chiropractic College.
After developing and implementing a hospital based clinical rotation for chiropractic interns at the Texas Medical Center in orthopedic surgery, Dr. Francis embarked on a mission to incorporate chiropractic services in the hospital setting by pioneering medical staff privileges for chiropractors. After successfully gaining full medial staff privileges for chiropractors at local Houston hospitals, Dr. Francis began to organize the academic programs to certify doctors of chiropractic in Manipulation Under Anesthesia (MUA) and Hospital Protocol.
After Dr. Francis was certified and proctored clinically in Manipulation Under Anesthesia (MUA) by board certified orthopedic surgeons, he was granted clinical privileges to admit patients to the hospital operating room for this procedure. Soon thereafter he developed a board approved MUA certification course for chiropractors that included hospital protocol, operating room proficiency and clincial proctorship in MUA under the auspices of the TCC Division of Post Graduate Studies.
The course became quite popular with a large number of chiropractors around the country seeking parity with medical physicians in the orthodox health care delivery system during the early 1990’s. Soon other colleges followed the TCC MUA model and began offering through post graduate programs the TCC-developed MUA certification course.
The hospital rotation program for chiropractic interns was developed during the same time period and became another TCC model for other colleges interested in providing chiropractic interns with the opportunity to rotate through hospitals and share chiropractic clinical models with their medical colleagues.
Dr. Francis initially personally selected the interns to rotate through the orthopedic service at the Texas Medical Center but soon the request by the medical staff and faculty for more chiropractic interns to rotate through services other than orthopedics allowed the program to expand to include rotations in family practice, internal medicine, radiology, neurosurgery, physical medicine and rheumatology.
Towards an effort to shepherd this rapid expansion in a meaningful fashion, Dr. Francis recruited other TCC faculty members to participate in the hospital rotation program for TCC interns. The faculty involved in the hospital based program monitored the activity and interaction between the interns, medical students, medical school faculty and attending physicians at the hospital subsequently leading to the to development of didactic presentations at Hospital Grand Rounds to the hospital staff, medical school physicians and faculty at the medical center hospitals.
Presentations on the Rationale for Spinal Manipulative Therapy, Skeletal Radiology, Diagnostic Imaging and other clinical presentations were made by the TCC faculty leading the way for further expansion of the program.
Dr. Francis currently holds appointment as Clinical Assistant Professor of Family Medicine in the Department of Family Medicine at the University of Texas Medical Branch in Galveston and has participated in federally funded research programs at the medical school to develop curriculum model for teaching CAM therapies to medical students.
Dr. Francis continues to teach the MUA certification courses around the country and has expanded the course to Europe teaching MUA to European chiropractors in Switzerland, Germany, Belgium and France.
The intern hospital rotation program continues to bridge the chasm of communication that once existed between the medical community and the chiropractic profession. -->

With relatively little federal funding, academic research in chiropractic has only recently become established in the USA. In 1994 and 1995, half of all grant funding to chiropractic researchers was from the US Health Resources and Services Administration (7 grants totaling $2.3 million). The Foundation for Chiropractic Education and Research (11 grants, $881,000) and the Consortium for Chiropractic Research (4 grants, $519,000) accounted for most of the rest. By 1997, there were 14 peer-reviewed chiropractic journals in English that encouraged the publication of chiropractic research, including ''The Journal of Manipulative and Physiological Therapeutics (JMPT)'', ''Topics in Clinical Chiropractic'', and the ''Journal of Chiropractic Humanities''. However, of these, only ''JMPT'' is included in Index Medicus. Research into chiropractic, whether from Universities or chiropractic colleges, is however often published in many other scientific journals.<ref>Chirofind.com </ref>

While there is still debate about the effectiveness of chiropractic for the many conditions in which it is applied, chiropractic seems to be most effective for acute low back pain and tension headaches.<ref name =Duke>McCrory DC, et al. (2001) ''Evidence Report: Behavioral and Physical Treatments for Tension-type and Cervicogenic Headache''. Duke University Evidence-Based Practice Center, Durham, North Carolina (] format)
</ref> When testing the efficacy of health treatments, ] studies are generally considered acceptable scientific rigor. These are designed so that neither the patient nor the doctor knows whether they are using the actual treatment or a placebo (or "sham") treatment. However, chiropractic treatment involves a ]; no "sham" procedure can be devised easily for this, and even if the patient is unaware whether the treatment is a real or sham procedure, the doctor cannot be unaware. Thus there may be "observer bias" - the tendency to see what you expect to see, and the potential for the patient to wish to report benefits to "please" the doctor. This problem is not confined to chiropractic - many medical treatments are not amenable to double-blind placebo-controlled trials, indeed this is true for all surgical procedures. It is also a problem in evaluating treatments; even when there are objective outcome measures, the ] can be very substantial. Thus, DCs have historically relied mostly on their own clinical experience and the shared experience of their colleagues, as reported in ], to direct their treatment methods. In this, they are not different to the practice in much of conventional medicine.


Chiropractic diagnosis may involve a range of methods including skeletal imaging, observational and tactile assessments, and orthopedic and neurological evaluation.<ref name=WHO-guidelines /> A chiropractor may also refer a patient to an appropriate specialist, or co-manage with another health care provider.<ref name=Meeker-Haldeman /> Common patient management involves ] (SM) and other manual therapies to the joints and soft tissues, rehabilitative exercises, health promotion, electrical modalities, complementary procedures, and lifestyle advice.<ref name=content-of-practice/>
Sociologist Leslie Biggs interviewed 600 Canadian DCs in 1997: while 86% felt that chiropractic methods needed to be validated, 74% did not believe that controlled clinical trials were the best way to evaluate chiropractic. Moreover, 68% believed that "most diseases are caused by spinal malalignment", although only 30% agreed that "subluxation was the cause of many diseases".<ref>Biggs L (2002) ''Measuring philosophy:
''a philosophy index'''' </ref>


]
Even when a valid mechanism of action is not determined, it is generally thought sufficient to present evidence showing benefit for the claims made. There is wide agreement that, where applicable, an ] framework should be used to assess health outcomes, and that systematic reviews with strict protocols are important for objectively evaluating treatments. Where evidence from such reviews is lacking, this does not necessarily mean that the treatment is ineffective, only that the case for a benefit of treatment may not have been rigorously established.

In 1997, historian Joseph Keating Jr described chiropractic as a "science, antiscience and pseudoscience", and said "Although available scientific data support chiropractic's principle intervention method (the manipulation of patients with lower back pain), the doubting, skeptical attitudes of science do not predominate in chiropractic education or among practitioners". He argued that chiropractic's culture has nurtured antiscientific attitudes and activities, and that "a combination of uncritical rationalism and uncritical empiricism has been bolstered by the proliferation of pseudoscience journals of chiropractic wherein poor quality research and exuberant over-interpretation of results masquerade as science and provide false confidence about the value of various chiropractic techniques". However, in 1998, after reviewing the articles published in the ''JMPT'' from 1989-1996, he concluded,
:"substantial increases in scholarly activities within the chiropractic profession are suggested by the growth in scholarly products published in the discipline's most distinguished periodical (JMPT). Increases in controlled outcome studies, collaboration among chiropractic institutions, contributions from nonchiropractors, contributions from nonchiropractic institutions and funding for research suggest a degree of professional maturation and growing interest in the content of the discipline."<ref>{{cite journal | author = Keating J ''et al.'' | title = A descriptive analysis of the Journal of Manipulative and Physiological Therapeutics, 1989-1996 | journal = J Manip Physiol Ther | volume = 21 | pages = 539-52 | year = 1998 | id = PMID 9798183}}</ref>

The Manga Report was an outcomes-study funded by the Ontario Ministry of Health and conducted by three health economists led by Professor ]. The Report supported the scientific validity, safety, efficacy, and cost-effectiveness of chiropractic for low-back pain, and found that chiropractic care had higher patient satisfaction levels than conventional alternatives. The report states that "The literature clearly and consistently shows that the major savings from chiropractic management come from fewer and lower costs of auxiliary services, fewer hospitalizations, and a highly significant reduction in chronic problems, as well as in levels and duration of disability."<ref>Manga P, Angus D.

In 1998, a study of 10,652 Florida workers' compensation cases was conducted by Steve Wolk. He concluded that "a claimant with a back-related injury, when initially treated by a chiropractor versus a medical doctor, is less likely to become temporarily disabled, or if disabled, remains disabled for a shorter period of time; and claimants treated by medical doctors were hospitalized at a much higher rate than claimants treated by chiropractors."<ref>Wolk S.

A 1989 study analyzed data on Iowa state records from individuals who filed claims for back or neck injuries. The study compared benefits and the cost of care from MDs, DCs and DOs, focusing on individuals who had missed days of work and who had received compensation for their injuries. Individuals who visited DCs missed on average 2.3 fewer days than those who visited MDs, and 3.8 fewer days than those who saw DOs, and accordingly, less money was dispersed as employment compensation on average for individuals who visited DCs.<ref>Johnson M.

Contemporary chiropractic can be divided into several approaches to patient care: all are based on non-invasive, non-medication approaches, with many based on the use of manipulation as a treatment for mechanical musculoskeletal dysfunction of the spine and extremities. Most chiropractors advertise themselves as primary care doctors, and consider themselves part of "alternative health care," but there can be large differences between practitioners.<ref name="Healey">James W. Healey, DC (1990) [http://www.chiroweb.com/archives/08/21/13.html It's Where You Put the Period. ''Dynamic Chiropractic''
October 10, 1990, Volume 08, Issue 21</ref> Those differences are reflected in the varied viewpoints of multiple national practice associations. While individual chiropractors may share the viewpoints of one or more organizations, most chiropractors are not actual members of any national organization.


=== Traditional Straight === === Risk-benefit ===


A 2012 systematic review concluded that no accurate assessment of risk-benefit exists for cervical manipulation.<ref name="Haynes" /> A 2010 systematic review stated that there is no good evidence to assume that neck manipulation is an effective treatment for any medical condition and suggested a ] in healthcare for chiropractic intervention even if a causality with ] after neck manipulation were merely a remote possibility.<ref name=Ernst-death/> The same review concluded that the risk of death from manipulations to the neck outweighs the benefits.<ref name=Ernst-death /> Chiropractors have criticized this conclusion, claiming that the author did not evaluate the potential benefits of spinal manipulation.<ref name=Ernst-response /> ] stated "This detail was not the subject of my review. I do, however, refer to such evaluations and should add that a report recently commissioned by the General Chiropractic Council did not support many of the outlandish claims made by many chiropractors across the world."<ref name=Ernst-response>{{cite journal | author = E Ernst | title = Response to critiques of deaths after chiropractic | journal = International Journal of Clinical Practice| volume = 65 | issue = 1 | page = 106 | year = 2011 | doi = 10.1111/j.1742-1241.2010.02568.x | s2cid = 72845939 | doi-access = free }}</ref> A 1999 review of 177 previously reported cases published between 1925 and 1997 in which injuries were attributed to manipulation of the cervical spine (MCS) concluded that "The literature does not demonstrate that the benefits of MCS outweigh the risks." The professions associated with each injury were assessed. Physical therapists (PT) were involved in less than 2% of all cases, with no deaths caused by PTs. Chiropractors were involved in a little more than 60% of all cases, including 32 deaths.<ref name="Di_Fabio_1/1/1999">{{cite web | last=Di Fabio | first=Richard P | date=January 1, 1999 | title=Manipulation of the Cervical Spine: Risks and Benefits | website=] | url=https://academic.oup.com/ptj/article/79/1/50/2857770 | access-date=November 1, 2021 | quote=Although the risk of injury associated with MCS appears to be small, this type of therapy has the potential to expose patients to vertebral artery damage that can be avoided with the use of mobilization (nonthrust passive movements). The literature does not demonstrate that the benefits of MCS outweigh the risks. Several recommendations for future studies and for the practice of MCS are discussed. }}</ref>
''Traditional Straight'' chiropractors are the oldest movement. They adhere to the philosophical principles set forth by DD and BJ Palmer; that vertebral subluxation leads to interference of the human nervous system and is a primary underlying risk factor for almost any disease. Straights adhere to the chiropractic diagnosis of subluxations, and view the medical diagnosis of patient complaints (which they consider to be the "secondary effects" of subluxations) to be unnecessary for treatment. Instead, patients are typically screened for "red flags" of serious disease, and treated based on a practitioner's preferred chiropractic technique. This stance against medical diagnosing has been a source of contention between mixers and straights, because accreditation standards mandate that differential diagnosis be taught in all chiropractic programs so that patient care is safe and relevant to their complaints. Additionally, several state chiropractic licensing boards mandate that patient complaints be diagnosed before receiving care. Traditional straights tend to share the viewpoints found in the ] (ICA), as well as the ] (FSCO) and the ] (WCA).


A 2009 review evaluating maintenance chiropractic care found that spinal manipulation is associated with considerable harm and no compelling evidence exists to indicate that it adequately prevents symptoms or diseases, thus the risk-benefit is not evidently favorable.<ref name="ErnstMaintenance2009">{{cite journal | author = Ernst E | title = Chiropractic maintenance treatment, a useful preventative approach? | journal = Preventive Medicine| volume = 49 | issue = 2–3 | pages = 99–100 | year = 2009 | pmid = 19465044 | doi = 10.1016/j.ypmed.2009.05.004 }}</ref>
=== Mixer ===


=== Cost-effectiveness ===
''Mixer'' chiropractors are an early offshoot of the straight movement. This branch originated from naturopathic, osteopathic, medical, and even chiropractic doctors who attended the ] and then re-organized the treatment system to include more diagnostic and treatment approaches. They eventually split from the traditional straight group and formed various other chiropractic schools including the ]. Their treatments may include naturopathic remedies, physical therapy devices, or other ] methods. While still subluxation based, mixers also treat problems associated with both the spine and extremities, including musculoskeletal issues such as pain and decreased range of motion. Mixers describe vertebral subluxations as a form of joint dysfunction or osteoarthritis. Diagnosis is made after ruling out other known disorders and noting general signs of mechanical dysfunction in the spine. Mixers tend to share the viewpoints found in the ], the ], and/or the ] (ACA), and all the major groups in Europe are also members of the ].<ref name="Souza">Souza T (2005) ''Differential Diagnosis and Management for the Chiropractor, Third Edition : Protocols and Algorithms'' Jones and Bartlett Publishers Inc. 3rd edition</ref>

A 2006 systematic cost-effectiveness review found that the reported cost-effectiveness of spinal manipulation in the United Kingdom compared favorably with other treatments for back pain, but that reports were based on data from clinical trials without placebo controls and that the specific cost-effectiveness of the treatment (as opposed to non-specific effects) remains uncertain.<ref>{{cite journal | vauthors = Canter PH, Coon JT, Ernst E | title = Cost-Effectiveness of Complementary Therapies in the United Kingdom&nbsp;– A Systematic Review† | journal = Evidence-Based Complementary and Alternative Medicine| volume = 3 | issue = 4 | pages = 425–32 | year = 2006 | pmid = 17173105 | pmc = 1697737 | doi = 10.1093/ecam/nel044 | url =http://ecam.oxfordjournals.org/cgi/content/full/3/4/425 | archive-url = https://web.archive.org/web/20080511154423/http://ecam.oxfordjournals.org/cgi/content/full/3/4/425 | archive-date = 2008-05-11 }}</ref> A 2005 American systematic review of economic evaluations of conservative treatments for low back pain found that significant quality problems in available studies meant that definite conclusions could not be drawn about the most cost-effective intervention.<ref>{{cite journal |vauthors=van der Roer N, Goossens ME, Evers SM, van Tulder MW | title = What is the most cost-effective treatment for patients with low back pain? a systematic review | journal = Best Practice & Research Clinical Rheumatology| volume = 19 | issue = 4 | pages = 671–84 | year = 2005 | pmid = 15949783 | doi = 10.1016/j.berh.2005.03.007 }}</ref> The cost-effectiveness of maintenance chiropractic care is unknown.<ref name=Leboeuf-Yde-C>{{cite journal |vauthors=Leboeuf-Yde C, Hestbaek L | title = Maintenance care in chiropractic&nbsp;– what do we know? | journal = Chiropractic & Osteopathy| volume = 16 | page = 3 | year = 2008 | pmid = 18466623 | pmc = 2396648 | doi = 10.1186/1746-1340-16-3 | doi-access = free }}</ref>{{Primary source inline|date=July 2021}}
''Objective Straight'' chiropractors<ref name="F.A.C.E._position_paper1"></ref> are a minority group and a recent off-shoot of the traditional straights. This group is differentiated from traditional straights mainly by the claims made. While traditional straights claimed that chiropractic adjustments are a plausible treatment for a wide range of diseases, objective straights only focus on the correction of chiropractic vertebral subluxations. Like traditional straights, objective straights typically do not diagnose patient complaints. Their guiding principles are summed up as: "We do not want to diagnose and treat diseases, even diseases of the spine." and "We do not want chiropractic to be practiced as an alternative to medicine."<ref name="F.A.C.E._3_principles"></ref> They also don't refer to other professionals, but do encourage their patients "to see a medical physician if they indicate that they want to be treated for the symptoms they are experiencing or if they would like a medical diagnosis to determine the cause of their symptoms."<ref name="F.A.C.E._referral"></ref> Most objective straights limit treatment to spinal adjustments.

Alternative diagnoses

Chiropractic (/ˌkaɪroʊˈpræktɪk/) is a form of alternative medicine concerned with the diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, especially of the spine. It is based on several pseudoscientific ideas.

Many chiropractors (often known informally as chiros), especially those in the field's early history, have proposed that mechanical disorders of the joints, especially of the spine, affect general health, and that regular manipulation of the spine (spinal adjustment) improves general health. The main chiropractic treatment technique involves manual therapy, especially manipulation of the spine, other joints, and soft tissues, but may also include exercises and health and lifestyle counseling. A chiropractor may have a Doctor of Chiropractic (D.C.) degree and be referred to as "doctor" but is not a Doctor of Medicine (M.D.) or a Doctor of Osteopathic Medicine (D.O.). While many chiropractors view themselves as primary care providers, chiropractic clinical training does not meet the requirements for that designation.

Systematic reviews of controlled clinical studies of treatments used by chiropractors have found no evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain. A 2011 critical evaluation of 45 systematic reviews concluded that the data included in the study "fail to demonstrate convincingly that spinal manipulation is an effective intervention for any condition." Spinal manipulation may be cost-effective for sub-acute or chronic low back pain, but the results for acute low back pain were insufficient. No compelling evidence exists to indicate that maintenance chiropractic care adequately prevents symptoms or diseases.

There is not sufficient data to establish the safety of chiropractic manipulations. It is frequently associated with mild to moderate adverse effects, with serious or fatal complications in rare cases. There is controversy regarding the degree of risk of vertebral artery dissection, which can lead to stroke and death, from cervical manipulation. Several deaths have been associated with this technique and it has been suggested that the relationship is causative, a claim which is disputed by many chiropractors.

Chiropractic is well established in the United States, Canada, and Australia. It overlaps with other manual-therapy professions such as osteopathy and physical therapy. Most who seek chiropractic care do so for low back pain. Back and neck pain are considered the specialties of chiropractic, but many chiropractors treat ailments other than musculoskeletal issues. Chiropractic has two main groups: "straights", now the minority, emphasize vitalism, "Innate Intelligence", and consider vertebral subluxations to be the cause of all disease; and "mixers", the majority, are more open to mainstream views and conventional medical techniques, such as exercise, massage, and ice therapy.

D. D. Palmer founded chiropractic in the 1890s, claiming that he had received it from "the other world". Palmer maintained that the tenets of chiropractic were passed along to him by a doctor who had died 50 years previously. His son B. J. Palmer helped to expand chiropractic in the early 20th century. Throughout its history, chiropractic has been controversial. Its foundation is at odds with evidence-based medicine, and is underpinned by pseudoscientific ideas such as vertebral subluxation and Innate Intelligence. Despite the overwhelming evidence that vaccination is an effective public health intervention, there are significant disagreements among chiropractors over the subject, which has led to negative impacts on both public vaccination and mainstream acceptance of chiropractic. The American Medical Association called chiropractic an "unscientific cult" in 1966 and boycotted it until losing an antitrust case in 1987. Chiropractic has had a strong political base and sustained demand for services. In the last decades of the twentieth century, it gained more legitimacy and greater acceptance among conventional physicians and health plans in the United States. During the COVID-19 pandemic, chiropractic professional associations advised chiropractors to adhere to CDC, WHO, and local health department guidance. Despite these recommendations, a small but vocal and influential number of chiropractors spread vaccine misinformation.

Conceptual basis

Philosophy

Chiropractic is generally categorized as complementary and alternative medicine (CAM), which focuses on manipulation of the musculoskeletal system, especially the spine. Its founder, D. D. Palmer, called it "a science of healing without drugs".

Chiropractic's origins lie in the folk medicine of bonesetting, and as it evolved it incorporated vitalism, spiritual inspiration and rationalism. Its early philosophy was based on deduction from irrefutable doctrine, which helped distinguish chiropractic from medicine, provided it with legal and political defenses against claims of practicing medicine without a license, and allowed chiropractors to establish themselves as an autonomous profession. This "straight" philosophy, taught to generations of chiropractors, rejects the inferential reasoning of the scientific method, and relies on deductions from vitalistic first principles rather than on the materialism of science. However, most practitioners tend to incorporate scientific research into chiropractic, and most practitioners are "mixers" who attempt to combine the materialistic reductionism of science with the metaphysics of their predecessors and with the holistic paradigm of wellness. A 2008 commentary proposed that chiropractic actively divorce itself from the straight philosophy as part of a campaign to eliminate untestable dogma and engage in critical thinking and evidence-based research.

  • Origin of holism in chiropractic
  • Cannot be proven or disproven
Taken from Mootz & Phillips 1997

Although a wide diversity of ideas exist among chiropractors, they share the belief that the spine and health are related in a fundamental way, and that this relationship is mediated through the nervous system. Some chiropractors claim spinal manipulation can have an effect on a variety of ailments such as irritable bowel syndrome and asthma.

Chiropractic philosophy includes the following perspectives:

Holism assumes that health is affected by everything in an individual's environment; some sources also include a spiritual or existential dimension. In contrast, reductionism in chiropractic reduces causes and cures of health problems to a single factor, vertebral subluxation. Homeostasis emphasizes the body's inherent self-healing abilities. Chiropractic's early notion of innate intelligence can be thought of as a metaphor for homeostasis.

A large number of chiropractors fear that if they do not separate themselves from the traditional vitalistic concept of innate intelligence, chiropractic will continue to be seen as a fringe profession. A variant of chiropractic called naprapathy originated in Chicago in the early twentieth century. It holds that manual manipulation of soft tissue can reduce "interference" in the body and thus improve health.

Straights and mixers

Range of belief perspectives in chiropractic
Perspective attribute Potential belief endpoints
Scope of practice: narrow ("straight") ← → broad ("mixer")
Diagnostic approach: intuitive ← → analytical
Philosophic orientation: vitalistic ← → materialistic
Scientific orientation: descriptive ← → experimental
Process orientation: implicit ← → explicit
Practice attitude: doctor/model-centered ← → patient/situation-centered
Professional integration: separate and distinct ← → integrated into mainstream
Taken from Mootz & Phillips 1997

Straight chiropractors adhere to the philosophical principles set forth by D. D. and B. J. Palmer, and retain metaphysical definitions and vitalistic qualities. Straight chiropractors believe that vertebral subluxation leads to interference with an "innate intelligence" exerted via the human nervous system and is a primary underlying risk factor for many diseases. Straights view the medical diagnosis of patient complaints, which they consider to be the "secondary effects" of subluxations, to be unnecessary for chiropractic treatment. Thus, straight chiropractors are concerned primarily with the detection and correction of vertebral subluxation via adjustment and do not "mix" other types of therapies into their practice style. Their philosophy and explanations are metaphysical in nature and they prefer to use traditional chiropractic lexicon terminology such as "perform spinal analysis", "detect subluxation", "correct with adjustment". They prefer to remain separate and distinct from mainstream health care. Although considered the minority group, "they have been able to transform their status as purists and heirs of the lineage into influence dramatically out of proportion to their numbers."

Mixer chiropractors "mix" diagnostic and treatment approaches from chiropractic, medical or osteopathic viewpoints and make up the majority of chiropractors. Unlike straight chiropractors, mixers believe subluxation is one of many causes of disease, and hence they tend to be open to mainstream medicine. Many of them incorporate mainstream medical diagnostics and employ conventional treatments including techniques of physical therapy such as exercise, stretching, massage, ice packs, electrical muscle stimulation, therapeutic ultrasound, and moist heat. Some mixers also use techniques from alternative medicine, including nutritional supplements, acupuncture, homeopathy, herbal remedies, and biofeedback.

Although mixers are the majority group, many of them retain belief in vertebral subluxation as shown in a 2003 survey of 1,100 North American chiropractors, which found that 88 percent wanted to retain the term "vertebral subluxation complex", and that when asked to estimate the percent of disorders of internal organs that subluxation significantly contributes to, the mean response was 62 percent. A 2008 survey of 6,000 American chiropractors demonstrated that most chiropractors seem to believe that a subluxation-based clinical approach may be of limited utility for addressing visceral disorders, and greatly favored non-subluxation-based clinical approaches for such conditions. The same survey showed that most chiropractors generally believed that the majority of their clinical approach for addressing musculoskeletal/biomechanical disorders such as back pain was based on subluxation. Chiropractors often offer conventional therapies such as physical therapy and lifestyle counseling, and it may for the lay person be difficult to distinguish the unscientific from the scientific.

Vertebral subluxation

Main article: Vertebral subluxation Not to be confused with subluxation, the medical condition.

In science-based medicine, the term "subluxation" refers to an incomplete or partial dislocation of a joint, from the Latin luxare for 'dislocate'. While medical doctors use the term exclusively to refer to physical dislocations, Chiropractic founder D. D. Palmer imbued the word subluxation with a metaphysical and philosophical meaning drawn from pseudoscientific traditions such as Vitalism.

Palmer claimed that vertebral subluxations interfered with the body's function and its inborn ability to heal itself. D. D. Palmer repudiated his earlier theory that vertebral subluxations caused pinched nerves in the intervertebral spaces in favor of subluxations causing altered nerve vibration, either too tense or too slack, affecting the tone (health) of the end organ. He qualified this by noting that knowledge of innate intelligence was not essential to the competent practice of chiropractic. This concept was later expanded upon by his son, B. J. Palmer, and was instrumental in providing the legal basis of differentiating chiropractic from conventional medicine. In 1910, D. D. Palmer theorized that the nervous system controlled health:

Physiologists divide nerve-fibers, which form the nerves, into two classes, afferent and efferent. Impressions are made on the peripheral afferent fiber-endings; these create sensations that are transmitted to the center of the nervous system. Efferent nerve-fibers carry impulses out from the center to their endings. Most of these go to muscles and are therefore called motor impulses; some are secretory and enter glands; a portion are inhibitory, their function being to restrain secretion. Thus, nerves carry impulses outward and sensations inward. The activity of these nerves, or rather their fibers, may become excited or allayed by impingement, the result being a modification of functionality – too much or not enough action – which is disease.

Chiropractors use x-ray radiography to examine the bone structure of a patient.

Vertebral subluxation, a core concept of traditional chiropractic, remains unsubstantiated and largely untested, and a debate about whether to keep it in the chiropractic paradigm has been ongoing for decades. In general, critics of traditional subluxation-based chiropractic (including chiropractors) are skeptical of its clinical value, dogmatic beliefs and metaphysical approach. While straight chiropractic still retains the traditional vitalistic construct espoused by the founders, evidence-based chiropractic suggests that a mechanistic view will allow chiropractic care to become integrated into the wider health care community. This is still a continuing source of debate within the chiropractic profession as well, with some schools of chiropractic still teaching the traditional/straight subluxation-based chiropractic, while others have moved towards an evidence-based chiropractic that rejects metaphysical foundings and limits itself to primarily neuromusculoskeletal conditions.

In 2005, the chiropractic subluxation was defined by the World Health Organization as "a lesion or dysfunction in a joint or motion segment in which alignment, movement integrity and/or physiological function are altered, although contact between joint surfaces remains intact. It is essentially a functional entity, which may influence biomechanical and neural integrity." This differs from the medical definition of subluxation as a significant structural displacement, which can be seen with static imaging techniques such as X-rays. The use of X-ray imaging in the case of vertebral subluxation exposes patients to harmful ionizing radiation for no evidentially supported reason. The 2008 book Trick or Treatment states "X-rays can reveal neither the subluxations nor the innate intelligence associated with chiropractic philosophy, because they do not exist." Attorney David Chapman-Smith, Secretary-General of the World Federation of Chiropractic, has stated that "Medical critics have asked how there can be a subluxation if it cannot be seen on X-ray. The answer is that the chiropractic subluxation is essentially a functional entity, not structural, and is therefore no more visible on static X-ray than a limp or headache or any other functional problem." The General Chiropractic Council, the statutory regulatory body for chiropractors in the United Kingdom, states that the chiropractic vertebral subluxation complex "is not supported by any clinical research evidence that would allow claims to be made that it is the cause of disease."

As of 2014, the US National Board of Chiropractic Examiners states "The specific focus of chiropractic practice is known as the chiropractic subluxation or joint dysfunction. A subluxation is a health concern that manifests in the skeletal joints, and, through complex anatomical and physiological relationships, affects the nervous system and may lead to reduced function, disability or illness."

Pseudoscience versus spinal manipulation therapy

Main articles: Spinal adjustment and Spinal manipulation

While some chiropractors limit their practice to short-term treatment of musculoskeletal conditions, many falsely claim to be able treat a myriad of other conditions. Some dissuade patients from seeking medical care, others have pretended to be qualified to act as a family doctor.

Quackwatch, an alternative medicine watchdog, cautions against seeing chiropractors who:

  • Treat young children
  • Discourage immunization
  • Pretend to be a family doctor
  • Take full spine X-rays
  • Promote unproven dietary supplements
  • Are antagonistic to scientific medicine
  • Claim to treat non-musculoskeletal problems

Writing for the Skeptical Inquirer, one physician cautioned against seeing even chiropractors who solely claim to treat musculoskeletal conditions:

I think Spinal Manipulation Therapy (SMT) is a reasonable option for patients to try ... But I could not in good conscience refer a patient to a chiropractor... When chiropractic is effective, what is effective is not 'chiropractic': it is SMT. SMT is also offered by physical therapists, DOs, and others. These are science-based providers ... If I thought a patient might benefit from manipulation, I would rather refer him or her to a science-based provider.

Scope of practice

A treatment table at a chiropractic office

Chiropractors emphasize the conservative management of the neuromusculoskeletal system without the use of medicines or surgery, with special emphasis on the spine. Back and neck pain are the specialties of chiropractic but many chiropractors treat ailments other than musculoskeletal issues. There is a range of opinions among chiropractors: some believed that treatment should be confined to the spine, or back and neck pain; others disagreed. For example, while one 2009 survey of American chiropractors had found that 73% classified themselves as "back pain/musculoskeletal specialists", the label "back and neck pain specialists" was regarded by 47% of them as a least desirable description in a 2005 international survey. Chiropractic combines aspects from mainstream and alternative medicine, and there is no agreement about how to define the profession: although chiropractors have many attributes of primary care providers, chiropractic has more attributes of a medical specialty like dentistry or podiatry. It has been proposed that chiropractors specialize in nonsurgical spine care, instead of attempting to also treat other problems, but the more expansive view of chiropractic is still widespread.

Mainstream health care and governmental organizations such as the World Health Organization consider chiropractic to be complementary and alternative medicine (CAM); and a 2008 study reported that 31% of surveyed chiropractors categorized chiropractic as CAM, 27% as integrated medicine, and 12% as mainstream medicine. Many chiropractors believe they are primary care providers, including US and UK chiropractors, but the length, breadth, and depth of chiropractic clinical training do not support the requirements to be considered primary care providers, so their role on primary care is limited and disputed.

Chiropractic overlaps with several other forms of manual therapy, including massage therapy, osteopathy, physical therapy, and sports medicine. Chiropractic is autonomous from and competitive with mainstream medicine, and osteopathy outside the US remains primarily a manual medical system; physical therapists work alongside and cooperate with mainstream medicine, and osteopathic medicine in the U.S. has merged with the medical profession. Practitioners may distinguish these competing approaches through claims that, compared to other therapists, chiropractors heavily emphasize spinal manipulation, tend to use firmer manipulative techniques, and promote maintenance care; that osteopaths use a wider variety of treatment procedures; and that physical therapists emphasize machinery and exercise.

Chiropractic diagnosis may involve a range of methods including skeletal imaging, observational and tactile assessments, and orthopedic and neurological evaluation. A chiropractor may also refer a patient to an appropriate specialist, or co-manage with another health care provider. Common patient management involves spinal manipulation (SM) and other manual therapies to the joints and soft tissues, rehabilitative exercises, health promotion, electrical modalities, complementary procedures, and lifestyle advice.

Chiropractors are not normally licensed to write medical prescriptions or perform major surgery in the United States (although New Mexico has become the first US state to allow "advanced practice" trained chiropractors to prescribe certain medications). In the US, their scope of practice varies by state, based on inconsistent views of chiropractic care: some states, such as Iowa, broadly allow treatment of "human ailments"; some, such as Delaware, use vague concepts such as "transition of nerve energy" to define scope of practice; others, such as New Jersey, specify a severely narrowed scope. US states also differ over whether chiropractors may conduct laboratory tests or diagnostic procedures, dispense dietary supplements, or use other therapies such as homeopathy and acupuncture; in Oregon they can become certified to perform minor surgery and to deliver children via natural childbirth. A 2003 survey of North American chiropractors found that a slight majority favored allowing them to write prescriptions for over-the-counter drugs. A 2010 survey found that 72% of Swiss chiropractors considered their ability to prescribe nonprescription medication as an advantage for chiropractic treatment.

A related field, veterinary chiropractic, applies manual therapies to animals and is recognized in many US states, but is not recognized by the American Chiropractic Association as being chiropractic. It remains controversial within certain segments of the veterinary and chiropractic professions.

No single profession "owns" spinal manipulation and there is little consensus as to which profession should administer SM, raising concerns by chiropractors that other medical physicians could "steal" SM procedures from chiropractors. A focus on evidence-based SM research has also raised concerns that the resulting practice guidelines could limit the scope of chiropractic practice to treating backs and necks. Two US states (Washington and Arkansas) prohibit physical therapists from performing SM, some states allow them to do it only if they have completed advanced training in SM, and some states allow only chiropractors to perform SM, or only chiropractors and physicians. Bills to further prohibit non-chiropractors from performing SM are regularly introduced into state legislatures and are opposed by physical therapist organizations.

Treatments

Main articles: Chiropractic treatment techniques and Spinal adjustment
A chiropractor performs an adjustment on a patient.

Spinal manipulation, which chiropractors call "spinal adjustment" or "chiropractic adjustment", is the most common treatment used in chiropractic care. Spinal manipulation is a passive manual maneuver during which a three-joint complex is taken past the normal range of movement, but not so far as to dislocate or damage the joint. Its defining factor is a dynamic thrust, which is a sudden force that causes an audible release and attempts to increase a joint's range of motion. High-velocity, low-amplitude spinal manipulation (HVLA-SM) thrusts have physiological effects that signal neural discharge from paraspinal muscle tissues, depending on duration and amplitude of the thrust are factors of the degree in paraspinal muscle spindles activation. Clinical skill in employing HVLA-SM thrusts depends on the ability of the practitioner to handle the duration and magnitude of the load. More generally, spinal manipulative therapy (SMT) describes techniques where the hands are used to manipulate, massage, mobilize, adjust, stimulate, apply traction to, or otherwise influence the spine and related tissues.

There are several schools of chiropractic adjustive techniques, although most chiropractors mix techniques from several schools. The following adjustive procedures were received by more than 10% of patients of licensed US chiropractors in a 2003 survey: Diversified technique (full-spine manipulation, employing various techniques), extremity adjusting, Activator technique (which uses a spring-loaded tool to deliver precise adjustments to the spine), Thompson Technique (which relies on a drop table and detailed procedural protocols), Gonstead (which emphasizes evaluating the spine along with specific adjustment that avoids rotational vectors), Cox/flexion-distraction (a gentle, low-force adjusting procedure which mixes chiropractic with osteopathic principles and utilizes specialized adjusting tables with movable parts), adjustive instrument, Sacro-Occipital Technique (which models the spine as a torsion bar), Nimmo Receptor-Tonus Technique, applied kinesiology (which emphasises "muscle testing" as a diagnostic tool), and cranial. Chiropractic biophysics technique uses inverse functions of rotations during spinal manipulation. Koren Specific Technique (KST) may use their hands, or they may use an electric device known as an "ArthroStim" for assessment and spinal manipulations. Insurers in the US and UK that cover other chiropractic techniques exclude KST from coverage because they consider it to be "experimental and investigational". Medicine-assisted manipulation, such as manipulation under anesthesia, involves sedation or local anesthetic and is done by a team that includes an anesthesiologist; a 2008 systematic review did not find enough evidence to make recommendations about its use for chronic low back pain.

Lumbar, cervical and thoracic chiropractic spinal manipulation

Many other procedures are used by chiropractors for treating the spine, other joints and tissues, and general health issues. The following procedures were received by more than one-third of patients of licensed US chiropractors in a 2003 survey: Diversified technique (full-spine manipulation; mentioned in previous paragraph), physical fitness/exercise promotion, corrective or therapeutic exercise, ergonomic/postural advice, self-care strategies, activities of daily living, changing risky/unhealthy behaviors, nutritional/dietary recommendations, relaxation/stress reduction recommendations, ice pack/cryotherapy, extremity adjusting (also mentioned in previous paragraph), trigger point therapy, and disease prevention/early screening advice.

A 2010 study describing Belgian chiropractors and their patients found chiropractors in Belgium mostly focus on neuromusculoskeletal complaints in adult patients, with emphasis on the spine. The diversified technique is the most often applied technique at 93%, followed by the Activator mechanical-assisted technique at 41%. A 2009 study assessing chiropractic students giving or receiving spinal manipulations while attending a United States chiropractic college found Diversified, Gonstead, and upper cervical manipulations are frequently used methods.

Practice guidelines

Reviews of research studies within the chiropractic community have been used to generate practice guidelines outlining standards that specify which chiropractic treatments are legitimate (i.e. supported by evidence) and conceivably reimbursable under managed care health payment systems. Evidence-based guidelines are supported by one end of an ideological continuum among chiropractors; the other end employs antiscientific reasoning and makes unsubstantiated claims. Chiropractic remains at a crossroads, and that in order to progress it would need to embrace science; the promotion by some for it to be a cure-all was both "misguided and irrational". A 2007 survey of Alberta chiropractors found that they do not consistently apply research in practice, which may have resulted from a lack of research education and skills. Specific guidelines concerning the treatment of nonspecific (i.e., unknown cause) low back pain are inconsistent between countries.

Effectiveness

Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with varied results. There is no conclusive evidence that chiropractic manipulative treatment is effective for the treatment of any medical condition, except perhaps for certain kinds of back pain.

Generally, the research carried out into the effectiveness of chiropractic has been of poor quality. Research published by chiropractors is distinctly biased: reviews of SM for back pain tended to find positive conclusions when authored by chiropractors, while reviews by mainstream authors did not.

There is a wide range of ways to measure treatment outcomes. Chiropractic care benefits from the placebo response, but it is difficult to construct a trustworthy placebo for clinical trials of spinal manipulative therapy (SMT). The efficacy of maintenance care in chiropractic is unknown.

Available evidence covers the following conditions:

  • Low back pain. A 2013 Cochrane review found very low to moderate evidence that SMT was no more effective than inert interventions, sham SMT or as an adjunct therapy for acute low back pain. The same review found that SMT appears to be no better than other recommended therapies. A 2012 overview of systematic reviews found that collectively, SM failed to show it is an effective intervention for pain. A 2011 Cochrane review found strong evidence that suggests there is no clinically meaningful difference between SMT and other treatments for reducing pain and improving function for chronic low back pain. A 2010 Cochrane review found no difference between the effects of combined chiropractic treatments and other treatments for chronic or mixed duration low back pain. A 2010 systematic review found that most studies suggest SMT achieves equivalent or superior improvement in pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up.
  • Radiculopathy. A 2013 systematic review and meta-analysis found a statistically significant improvement in overall recovery from sciatica following SM, when compared to usual care, and suggested that SM may be considered. There is moderate quality evidence to support the use of SM for the treatment of acute lumbar radiculopathy and acute lumbar disc herniation with associated radiculopathy. There is low or very low evidence supporting SM for chronic lumbar spine-related extremity symptoms and cervical spine-related extremity symptoms of any duration and no evidence exists for the treatment of thoracic radiculopathy.
  • Whiplash and other neck pain. There is no consensus on the effectiveness of manual therapies for neck pain. A 2013 systematic review found that the data suggests that there are minimal short- and long-term treatment differences when comparing manipulation or mobilization of the cervical spine to physical therapy or exercise for neck pain improvement. A 2013 systematic review found that although there is insufficient evidence that thoracic SM is more effective than other treatments, it is a suitable intervention to treat some patients with non-specific neck pain. A 2011 systematic review found that thoracic SM may offer short-term improvement for the treatment of acute or subacute mechanical neck pain; although the body of literature is still weak. A 2010 Cochrane review found low quality evidence that suggests cervical manipulation may offer better short-term pain relief than a control for neck pain, and moderate evidence that cervical manipulation and mobilization produced similar effects on pain, function and patient satisfaction. A 2010 systematic review found low level evidence that suggests chiropractic care improves cervical range of motion and pain in the management of whiplash.
  • Headache. There is conflicting evidence surrounding the use of chiropractic SMT for the treatment and prevention of migraine headaches. A 2006 review found no rigorous evidence supporting SM or other manual therapies for tension headache. A 2005 review found that the evidence was weak for effectiveness of chiropractic manipulation for tension headache, and that it was probably more effective for tension headache than for migraine.
  • Extremity conditions. A 2011 systematic review and meta-analysis concluded that the addition of manual mobilizations to an exercise program for the treatment of knee osteoarthritis resulted in better pain relief than a supervised exercise program alone and suggested that manual therapists consider adding manual mobilization to optimize supervised active exercise programs. There is silver level evidence that manual therapy is more effective than exercise for the treatment of hip osteoarthritis, however this evidence could be considered to be inconclusive. There is a small amount of research into the efficacy of chiropractic treatment for upper limbs, limited to low level evidence supporting chiropractic management of shoulder pain and limited or fair evidence supporting chiropractic management of leg conditions.
  • Other. A 2012 systematic review found insufficient low bias evidence to support the use of spinal manipulation as a therapy for the treatment of hypertension. A 2011 systematic review found moderate evidence to support the use of manual therapy for cervicogenic dizziness. There is very weak evidence for chiropractic care for adult scoliosis (curved or rotated spine) and no scientific data for idiopathic adolescent scoliosis. A 2007 systematic review found that few studies of chiropractic care for nonmusculoskeletal conditions are available, and they are typically not of high quality; it also found that the entire clinical encounter of chiropractic care (as opposed to just SM) provides benefit to patients with cervicogenic dizziness, and that the evidence from reviews is negative, or too weak to draw conclusions, for a wide variety of other nonmusculoskeletal conditions, including ADHD/learning disabilities, dizziness, high blood pressure, and vision conditions. Other reviews have found no evidence of significant benefit for asthma, baby colic, bedwetting, carpal tunnel syndrome, fibromyalgia, gastrointestinal disorders, kinetic imbalance due to suboccipital strain (KISS) in infants, menstrual cramps, insomnia, postmenopausal symptoms, or pelvic and back pain during pregnancy. As there is no evidence of effectiveness or safety for cervical manipulation for baby colic, it is not endorsed.

Safety

Chiropractic adjustment on children

The World Health Organization found chiropractic care in general is safe when employed skillfully and appropriately. There is not sufficient data to establish the safety of chiropractic manipulations. Manipulation is regarded as relatively safe but complications can arise, and it has known adverse effects, risks and contraindications. Absolute contraindications to spinal manipulative therapy are conditions that should not be manipulated; these contraindications include rheumatoid arthritis and conditions known to result in unstable joints. Relative contraindications are conditions where increased risk is acceptable in some situations and where low-force and soft-tissue techniques are treatments of choice; these contraindications include osteoporosis. Although most contraindications apply only to manipulation of the affected region, some neurological signs indicate referral to emergency medical services; these include sudden and severe headache or neck pain unlike that previously experienced. Indirect risks of chiropractic involve delayed or missed diagnoses through consulting a chiropractor.

Spinal manipulation is associated with frequent, mild and temporary adverse effects, including new or worsening pain or stiffness in the affected region. They have been estimated to occur in 33% to 61% of patients, and frequently occur within an hour of treatment and disappear within 24 to 48 hours; adverse reactions appear to be more common following manipulation than mobilization. The most frequently stated adverse effects are mild headache, soreness, and briefly elevated pain fatigue. Chiropractic is correlated with a very high incidence of minor adverse effects. Rarely, spinal manipulation, particularly on the upper spine, can also result in complications that can lead to permanent disability or death; these can occur in adults and children. Estimates vary widely for the incidence of these complications, and the actual incidence is unknown, due to high levels of underreporting and to the difficulty of linking manipulation to adverse effects such as stroke, which is a particular concern. Adverse effects are poorly reported in recent studies investigating chiropractic manipulations. A 2016 systematic review concludes that the level of reporting is unsuitable and unacceptable. Reports of serious adverse events have occurred, resulting from spinal manipulation therapy of the lumbopelvic region. Estimates for serious adverse events vary from 5 strokes per 100,000 manipulations to 1.46 serious adverse events per 10 million manipulations and 2.68 deaths per 10 million manipulations, though it was determined that there was inadequate data to be conclusive. Several case reports show temporal associations between interventions and potentially serious complications. The published medical literature contains reports of 26 deaths since 1934 following chiropractic manipulations and many more seem to remain unpublished.

Vertebrobasilar artery stroke (VAS) is statistically associated with chiropractic services in persons under 45 years of age, but it is similarly associated with general practitioner services, suggesting that these associations are likely explained by preexisting conditions. Weak to moderately strong evidence supports causation (as opposed to statistical association) between cervical manipulative therapy (CMT) and VAS. There is insufficient evidence to support a strong association or no association between cervical manipulation and stroke. While the biomechanical evidence is not sufficient to support the statement that CMT causes cervical artery dissection (CD), clinical reports suggest that mechanical forces have a part in a substantial number of CDs and the majority of population controlled studies found an association between CMT and VAS in young people. It is strongly recommended that practitioners consider the plausibility of CD as a symptom, and people can be informed of the association between CD and CMT before administering manipulation of the cervical spine. There is controversy regarding the degree of risk of stroke from cervical manipulation. Many chiropractors state that, the association between chiropractic therapy and vertebral arterial dissection is not proven. However, it has been suggested that the causality between chiropractic cervical manipulation beyond the normal range of motion and vascular accidents is probable or definite. There is very low evidence supporting a small association between internal carotid artery dissection and chiropractic neck manipulation. The incidence of internal carotid artery dissection following cervical spine manipulation is unknown. The literature infrequently reports helpful data to better understand the association between cervical manipulative therapy, cervical artery dissection and stroke. The limited evidence is inconclusive that chiropractic spinal manipulation therapy is not a cause of intracranial hypotension. Cervical intradural disc herniation is very rare following spinal manipulation therapy.

Chiropractors sometimes employ diagnostic imaging techniques such as X-rays and CT scans that rely on ionizing radiation. Although there is no clear evidence to justify the practice, some chiropractors still X-ray a patient several times a year. Practice guidelines aim to reduce unnecessary radiation exposure, which increases cancer risk in proportion to the amount of radiation received. Research suggests that radiology instruction given at chiropractic schools worldwide seem to be evidence-based. Although, there seems to be a disparity between some schools and available evidence regarding the aspect of radiography for patients with acute low back pain without an indication of a serious disease, which may contribute to chiropractic overuse of radiography for low back pain.

Risk-benefit

A 2012 systematic review concluded that no accurate assessment of risk-benefit exists for cervical manipulation. A 2010 systematic review stated that there is no good evidence to assume that neck manipulation is an effective treatment for any medical condition and suggested a precautionary principle in healthcare for chiropractic intervention even if a causality with vertebral artery dissection after neck manipulation were merely a remote possibility. The same review concluded that the risk of death from manipulations to the neck outweighs the benefits. Chiropractors have criticized this conclusion, claiming that the author did not evaluate the potential benefits of spinal manipulation. Edzard Ernst stated "This detail was not the subject of my review. I do, however, refer to such evaluations and should add that a report recently commissioned by the General Chiropractic Council did not support many of the outlandish claims made by many chiropractors across the world." A 1999 review of 177 previously reported cases published between 1925 and 1997 in which injuries were attributed to manipulation of the cervical spine (MCS) concluded that "The literature does not demonstrate that the benefits of MCS outweigh the risks." The professions associated with each injury were assessed. Physical therapists (PT) were involved in less than 2% of all cases, with no deaths caused by PTs. Chiropractors were involved in a little more than 60% of all cases, including 32 deaths.

A 2009 review evaluating maintenance chiropractic care found that spinal manipulation is associated with considerable harm and no compelling evidence exists to indicate that it adequately prevents symptoms or diseases, thus the risk-benefit is not evidently favorable.

Cost-effectiveness

A 2012 systematic review suggested that the use of spine manipulation in clinical practice is a cost-effective treatment when used alone or in combination with other treatment approaches. A 2011 systematic review found evidence supporting the cost-effectiveness of using spinal manipulation for the treatment of sub-acute or chronic low back pain; the results for acute low back pain were insufficient.

A 2006 systematic cost-effectiveness review found that the reported cost-effectiveness of spinal manipulation in the United Kingdom compared favorably with other treatments for back pain, but that reports were based on data from clinical trials without placebo controls and that the specific cost-effectiveness of the treatment (as opposed to non-specific effects) remains uncertain. A 2005 American systematic review of economic evaluations of conservative treatments for low back pain found that significant quality problems in available studies meant that definite conclusions could not be drawn about the most cost-effective intervention. The cost-effectiveness of maintenance chiropractic care is unknown.

Analysis of a clinical and cost utilization data from the years 2003 to 2005 by an integrative medicine independent physician association (IPA) which looked the chiropractic services utilization found that the clinical and cost utilization of chiropractic services based on 70,274 member-months over a 7-year period decreased patient costs associate with the following use of services by 60% for in-hospital admissions, 59% for hospital days, 62% for outpatient surgeries and procedures, and 85% for pharmaceutical costs when compared with conventional medicine (visit to a medical doctor primary care provider) IPA performance for the same health maintenance organization product in the same geography and time frame.

Education, licensing, and regulation

Main articles: Chiropractic education and List of chiropractic schools

Requirements vary between countries. In the U.S. chiropractors obtain a non-medical accredited diploma in the field of chiropractic. Chiropractic education in the U.S. has been criticized for failing to meet generally accepted standards of evidence-based medicine. The curriculum content of North American chiropractic and medical colleges with regard to basic and clinical sciences has little similarity, both in the kinds of subjects offered and in the time assigned to each subject. Accredited chiropractic programs in the U.S. require that applicants have 90 semester hours of undergraduate education with a grade point average of at least 3.0 on a 4.0 scale. Many programs require at least three years of undergraduate education, and more are requiring a bachelor's degree. Canada requires a minimum three years of undergraduate education for applicants, and at least 4200 instructional hours (or the equivalent) of full-time chiropractic education for matriculation through an accredited chiropractic program. Graduates of the Canadian Memorial Chiropractic College (CMCC) are formally recognized to have at least 7–8 years of university level education. The World Health Organization (WHO) guidelines suggest three major full-time educational paths culminating in either a DC, DCM, BSc, or MSc degree. Besides the full-time paths, they also suggest a conversion program for people with other health care education and limited training programs for regions where no legislation governs chiropractic.

Upon graduation, there may be a requirement to pass national, state, or provincial board examinations before being licensed to practice in a particular jurisdiction. Depending on the location, continuing education may be required to renew these licenses. Specialty training is available through part-time postgraduate education programs such as chiropractic orthopedics and sports chiropractic, and through full-time residency programs such as radiology or orthopedics.

In the U.S., chiropractic schools are accredited through the Council on Chiropractic Education (CCE) while the General Chiropractic Council (GCC) is the statutory governmental body responsible for the regulation of chiropractic in the UK. The U.S. CCE requires a mixing curriculum, which means a straight-educated chiropractor may not be eligible for licensing in states requiring CCE accreditation. CCEs in the U.S., Canada, Australia and Europe have joined to form CCE-International (CCE-I) as a model of accreditation standards with the goal of having credentials portable internationally. Today, there are 18 accredited Doctor of Chiropractic programs in the U.S., 2 in Canada, 6 in Australasia, and 5 in Europe. All but one of the chiropractic colleges in the U.S. are privately funded, but in several other countries they are in government-sponsored universities and colleges. Of the two chiropractic colleges in Canada, one is publicly funded (UQTR) and one is privately funded (CMCC). In 2005, CMCC was granted the privilege of offering a professional health care degree under the Post-secondary Education Choice and Excellence Act, which sets the program within the hierarchy of education in Canada as comparable to that of other primary contact health care professions such as medicine, dentistry and optometry.

Regulatory colleges and chiropractic boards in the U.S., Canada, Mexico, and Australia are responsible for protecting the public, standards of practice, disciplinary issues, quality assurance and maintenance of competency. There are an estimated 49,000 chiropractors in the U.S. (2008), 6,500 in Canada (2010), 2,500 in Australia (2000), and 1,500 in the UK (2000).

Chiropractors often argue that this education is as good as or better than medical physicians', but most chiropractic training is confined to classrooms with much time spent learning theory, adjustment, and marketing. The fourth year of chiropractic education persistently showed the highest stress levels. Every student, irrespective of year, experienced different ranges of stress when studying. The chiropractic leaders and colleges have had internal struggles. Rather than cooperation, there has been infighting between different factions. A number of actions were posturing due to the confidential nature of the chiropractic colleges in an attempt to enroll students.

In 2024, Oregon Public Broadcasting reported on the high debt burden of students who pursued degrees in alternative medicine. Ten different chiropractic programs were ranked among the 47 US graduate programs with highest debt to earnings ratios. Analyses by Quackwatch and the Sunlight Foundation found high rates of default on Health Education Assistance Loan (HEAL) student loans used for chiropractic programs. Among health professionals who were listed as in default on HEAL loans in 2012, 53% were chiropractors.

Ethics

Main article: Chiropractic professional ethics

The chiropractic oath is a modern variation of the classical Hippocratic Oath historically taken by physicians and other healthcare professionals swearing to practice their professions ethically. The American Chiropractic Association (ACA) has an ethical code "based upon the acknowledgement that the social contract dictates the profession's responsibilities to the patient, the public, and the profession; and upholds the fundamental principle that the paramount purpose of the chiropractic doctor's professional services shall be to benefit the patient." The International Chiropractor's Association (ICA) also has a set of professional canons.

A 2008 commentary proposed that the chiropractic profession actively regulate itself to combat abuse, fraud, and quackery, which are more prevalent in chiropractic than in other health care professions, violating the social contract between patients and physicians. According to a 2015 Gallup poll of U.S. adults, the perception of chiropractors is generally favorable; two-thirds of American adults agree that chiropractors have their patient's best interest in mind and more than half also agree that most chiropractors are trustworthy. Less than 10% of US adults disagreed with the statement that chiropractors were trustworthy.

The charity Sense about Science launched a campaign to draw attention to the BCA legal case against science writer Simon Singh. In 2009, a number of organizations and public figures signed a statement entitled "The law has no place in scientific disputes".

Chiropractors, especially in America, have a reputation for unnecessarily treating patients. In many circumstances the focus seems to be put on economics instead of health care. Sustained chiropractic care is promoted as a preventive tool, but unnecessary manipulation could possibly present a risk to patients. Some chiropractors are concerned by the routine unjustified claims chiropractors have made. A 2010 analysis of chiropractic websites found the majority of chiropractors and their associations made claims of effectiveness not supported by scientific evidence, while 28% of chiropractor websites advocate lower back pain care, which has some sound evidence.

The US Office of the Inspector General (OIG) estimated that for calendar year 2013, 82% of payments to chiropractors under Medicare Part B, a total of $359 million, did not comply with Medicare requirements. There have been at least 15 OIG reports about chiropractic billing irregularities since 1986.

In 2009, a backlash to the libel suit filed by the British Chiropractic Association (BCA) against Simon Singh inspired the filing of formal complaints of false advertising against more than 500 individual chiropractors within one 24-hour period, prompting the McTimoney Chiropractic Association to write to its members advising them to remove leaflets that make claims about whiplash and colic from their practice, to be wary of new patients and telephone inquiries, and telling their members: "If you have a website, take it down NOW" and "Finally, we strongly suggest you do NOT discuss this with others, especially patients." An editorial in Nature suggested that the BCA may have been trying to suppress debate and that this use of English libel law was a burden on the right to freedom of expression, which is protected by the European Convention on Human Rights. The libel case ended with the BCA withdrawing its suit in 2010.

Reception

Chiropractic is established in the U.S., Canada, and Australia, and is present to a lesser extent in many other countries. It is viewed as a marginal and non-clinically–proven attempt at complementary and alternative medicine, which has not integrated into mainstream medicine.

Australia

In Australia, there are approximately 2488 chiropractors, or one chiropractor for every 7980 people. Most private health insurance funds in Australia cover chiropractic care, and the federal government funds chiropractic care when the patient is referred by a medical practitioner. In 2014, the chiropractic profession had a registered workforce of 4,684 practitioners in Australia represented by two major organizations – the Chiropractors' Association of Australia (CAA) and the Chiropractic and Osteopathic College of Australasia (COCA). Annual expenditure on chiropractic care (alone or combined with osteopathy) in Australia is estimated to be between AUD$750–988 million with musculoskeletal complaints such as back and neck pain making up the bulk of consultations; and proportional expenditure is similar to that found in other countries. While Medicare (the Australian publicly funded universal health care system) coverage of chiropractic services is limited to only those directed by a medical referral to assist chronic disease management, most private health insurers in Australia do provide partial reimbursement for a wider range of chiropractic services in addition to limited third party payments for workers compensation and motor vehicle accidents.

Of the 2,005 chiropractors who participated in a 2015 survey, 62.4% were male and the average age was 42.1 (SD = 12.1) years. Nearly all chiropractors (97.1%) had a bachelor's degree or higher, with the majority of chiropractor's highest professional qualification being a bachelor or double bachelor's degree (34.6%), followed by a master's degree (32.7%), Doctor of Chiropractic (28.9%) or PhD (0.9%). Only a small number of chiropractor's highest professional qualification was a diploma (2.1%) or advanced diploma (0.8%).

Germany

In Germany, chiropractic may be offered by medical doctors and alternative practitioners. Chiropractors qualified abroad must obtain a German non-medical practitioner license. Authorities have routinely required a comprehensive knowledge test for this, but in the recent past, some administrative courts have ruled that training abroad should be recognised.

Switzerland

In Switzerland, only trained medical professionals are allowed to offer chiropractic. There are 300 chiropractors in Switzerland.

United Kingdom

In the United Kingdom, there are over 2,000 chiropractors, representing one chiropractor per 29,206 people. Chiropractic is available on the National Health Service in some areas, such as Cornwall, where the treatment is only available for neck or back pain.

A 2010 study by questionnaire presented to UK chiropractors indicated only 45% of chiropractors disclosed to patients the serious risk associated with manipulation of the cervical spine and that 46% believed there was possibility patients would refuse treatment if the risks were correctly explained. However 80% acknowledged the ethical/moral responsibility to disclose risk to patients.

United States and Canada

The percentage of the population that utilizes chiropractic care at any given time generally falls into a range from 6% to 12% in the U.S. and Canada, with a global high of 20% in Alberta in 2006. In 2008, chiropractors were reported to be the most common CAM providers for children and adolescents, these patients representing up to 14% of all visits to chiropractors.

There were around 50,330 chiropractors practicing in North America in 2000. In 2008, this has increased by almost 20% to around 60,000 chiropractors. In 2002–03, the majority of those who sought chiropractic did so for relief from back and neck pain and other neuromusculoskeletal complaints; most do so specifically for low back pain. The majority of U.S. chiropractors participate in some form of managed care. Although the majority of U.S. chiropractors view themselves as specialists in neuromusculoskeletal conditions, many also consider chiropractic as a type of primary care. In the majority of cases, the care that chiropractors and physicians provide divides the market, however for some, their care is complementary.

In the U.S., chiropractors perform over 90% of all manipulative treatments. Satisfaction rates are typically higher for chiropractic care compared to medical care, with a 1998 U.S. survey reporting 83% of respondents satisfied or very satisfied with their care; quality of communication seems to be a consistent predictor of patient satisfaction with chiropractors.

Utilization of chiropractic care is sensitive to the costs incurred by the co-payment by the patient. The use of chiropractic declined from 9.9% of U.S. adults in 1997 to 7.4% in 2002; this was the largest relative decrease among CAM professions, which overall had a stable use rate. As of 2007 7% of the U.S. population is being reached by chiropractic. They were the third largest medical profession in the US in 2002, following physicians and dentists. Employment of U.S. chiropractors was expected to increase 14% between 2006 and 2016, faster than the average for all occupations.

In the U.S., most states require insurers to cover chiropractic care, and most HMOs cover these services.

History

Main article: History of chiropractic
Daniel David (D. D.) Palmer, founder of chiropractic

Chiropractic's origins lie in the folk medicine practice of bonesetting, in which untrained practitioners engaged in joint manipulation or resetting fractured bones. Chiropractic was founded in 1895 by Daniel David (D. D.) Palmer in Davenport, Iowa. Palmer, a magnetic healer, hypothesized that manual manipulation of the spine could cure disease. The first chiropractic patient of D. D. Palmer was Harvey Lillard, a worker in the building where Palmer's office was located. He claimed that he had severely reduced hearing for 17 years, which started shortly following a "pop" in his spine. A few days following his adjustment, Lillard claimed his hearing was almost completely restored. Another of Palmer's patients, Samuel Weed, coined the term chiropractic, from Greek χειρο- chiro- 'hand' (itself from χείρ cheir 'hand') and πρακτικός praktikos 'practical'. Chiropractic is classified as a field of pseudomedicine.

Chiropractic competed with its predecessor osteopathy, another medical system based on magnetic healing; both systems were founded by charismatic midwesterners in opposition to the conventional medicine of the day, and both postulated that manipulation improved health. Although initially keeping chiropractic a family secret, in 1898 Palmer began teaching it to a few students at his new Palmer School of Chiropractic. One student, his son Bartlett Joshua (B. J.) Palmer, became committed to promoting chiropractic, took over the Palmer School in 1906, and rapidly expanded its enrollment.

Early chiropractors believed that all disease was caused by interruptions in the flow of innate intelligence, a vitalistic nervous energy or life force that represented God's presence in man; chiropractic leaders often invoked religious imagery and moral traditions. D. D. Palmer said he "received chiropractic from the other world". D. D. and B. J. both seriously considered declaring chiropractic a religion, which might have provided legal protection under the U.S. constitution, but decided against it partly to avoid confusion with Christian Science. Early chiropractors also tapped into the Populist movement, emphasizing craft, hard work, competition, and advertisement, aligning themselves with the common man against intellectuals and trusts, among which they included the American Medical Association (AMA).

B. J. Palmer, early developer of chiropractic

Chiropractic has seen considerable controversy and criticism. Although D. D. and B. J. were "straight" and disdained the use of instruments, some early chiropractors, whom B. J. scornfully called "mixers", advocated the use of instruments. In 1910, B. J. changed course and endorsed X-rays as necessary for diagnosis; this resulted in a significant exodus from the Palmer School of the more conservative faculty and students. The mixer camp grew until by 1924 B. J. estimated that only 3,000 of the United States' 25,000 chiropractors remained straight. That year, B. J.'s invention and promotion of the neurocalometer, a temperature-sensing device, was highly controversial among B. J.'s fellow straights. By the 1930s, chiropractic was the largest alternative healing profession in the U.S.

Harvey Lillard, first chiropractic patient

Chiropractors faced heavy opposition from organized medicine. D. D. Palmer was jailed in 1907 for practicing medicine without a license. Thousands of chiropractors were prosecuted for practicing medicine without a license, and D. D. and many other chiropractors were jailed. To defend against medical statutes, B. J. argued that chiropractic was separate and distinct from medicine, asserting that chiropractors "analyzed" rather than "diagnosed", and "adjusted" subluxations rather than "treated" disease. B. J. cofounded the Universal Chiropractors' Association (UCA) to provide legal services to arrested chiropractors. Although the UCA won their first test case in Wisconsin in 1907, prosecutions instigated by state medical boards became increasingly common and in many cases were successful. In response, chiropractors conducted political campaigns to secure separate licensing statutes, eventually succeeding in all fifty states, from Kansas in 1913 through Louisiana in 1974. The longstanding feud between chiropractors and medical doctors continued for decades.

Restraint of trade decision 1989

The AMA labeled chiropractic an "unscientific cult" in 1966, and until 1980 advised its members that it was unethical for medical doctors to associate with "unscientific practitioners". This culminated in a landmark 1987 decision, Wilk v. AMA, in which the court found that the AMA had engaged in unreasonable restraint of trade and conspiracy, and which ended the AMA's de facto boycott of chiropractic.

Growing scholarly interest

Serious research to test chiropractic theories did not begin until the 1970s, and is continuing to be hampered by antiscientific and pseudoscientific ideas that sustained the profession in its long battle with organized medicine. By the mid-1990s there was a growing scholarly interest in chiropractic, which helped efforts to improve service quality and establish clinical guidelines that recommended manual therapies for acute low back pain.

In recent decades chiropractic gained legitimacy and greater acceptance by medical physicians and health plans, and enjoyed a strong political base and sustained demand for services. However, its future seemed uncertain: as the number of practitioners grew, evidence-based medicine insisted on treatments with demonstrated value, managed care restricted payment, and competition grew from massage therapists and other health professions. The profession responded by marketing natural products and devices more aggressively, and by reaching deeper into alternative medicine and primary care.

Public health

Further information: Vaccine controversy § Alternative medicine, and Water fluoridation controversy

Some chiropractors oppose vaccination and water fluoridation, which are common public health practices. Within the chiropractic community there are significant disagreements about vaccination, one of the most cost-effective public health interventions available. Most chiropractic writings on vaccination focus on its negative aspects, claiming that it is hazardous, ineffective, and unnecessary. Some chiropractors have embraced vaccination, but a significant portion of the profession rejects it, as original chiropractic philosophy traces diseases to causes in the spine and states that vaccines interfere with healing. The extent to which anti-vaccination views perpetuate the current chiropractic profession is uncertain. The American Chiropractic Association and the International Chiropractors Association support individual exemptions to compulsory vaccination laws, and a 1995 survey of U.S. chiropractors found that about a third believed there was no scientific proof that immunization prevents disease. The Canadian Chiropractic Association supports vaccination; a survey in Alberta in 2002 found that 25% of chiropractors advised patients for, and 27% against, vaccinating themselves or their children.

Early opposition to water fluoridation included chiropractors, some of whom continue to oppose it as being incompatible with chiropractic philosophy and an infringement of personal freedom. Other chiropractors have actively promoted fluoridation, and several chiropractic organizations have endorsed scientific principles of public health. In addition to traditional chiropractic opposition to water fluoridation and vaccination, chiropractors' attempts to establish a positive reputation for their public health role are also compromised by their reputation for recommending repetitive lifelong chiropractic treatment.

Controversy

Main article: Chiropractic controversy and criticism

Throughout its history chiropractic has been the subject of internal and external controversy and criticism. According to Daniel D. Palmer, the founder of chiropractic, subluxation is the sole cause of disease and manipulation is the cure for all diseases of the human race. A 2003 profession-wide survey found "most chiropractors (whether 'straights' or 'mixers') still hold views of innate intelligence and of the cause and cure of disease (not just back pain) consistent with those of the Palmers." A critical evaluation stated "Chiropractic is rooted in mystical concepts. This led to an internal conflict within the chiropractic profession, which continues today." Chiropractors, including D. D. Palmer, were jailed for practicing medicine without a license. For most of its existence, chiropractic has battled with mainstream medicine, sustained by antiscientific and pseudoscientific ideas such as subluxation. Collectively, systematic reviews have not demonstrated that spinal manipulation, the main treatment method employed by chiropractors, is effective for any medical condition, with the possible exception of treatment for back pain. Chiropractic remains controversial, though to a lesser extent than in past years.

Retrieved 2008-06-16. A significant and continuing barrier to scientific progress within chiropractic are the anti-scientific and pseudo-scientific ideas (Keating 1997b) which have sustained the profession throughout a century of intense struggle with political medicine. Chiropractors' tendency to assert the meaningfulness of various theories and methods as a counterpoint to allopathic charges of quackery has created a defensiveness which can make critical examination of chiropractic concepts difficult (Keating and Mootz 1989). One example of this conundrum is the continuing controversy about the presumptive target of DCs' adjustive interventions: subluxation (Gatterman 1995; Leach 1994).

Although the risk of injury associated with MCS appears to be small, this type of therapy has the potential to expose patients to vertebral artery damage that can be avoided with the use of mobilization (nonthrust passive movements). The literature does not demonstrate that the benefits of MCS outweigh the risks. Several recommendations for future studies and for the practice of MCS are discussed.
