Spinal adjustment is a term used by chiropractors to describe any of a number of specialized spinal manipulations which are claimed to improve the alignment and/or motion of spinal and extremity joints. The procedures make up the mainstay of chiropractic treatment, but may be supplemented with exercise, electrical modalities and nutritional recommendations.
Many chiropractors believe that spinal adjustment is different from the spinal manipulation performed by physical therapists and osteopaths because the latter never try to improve vertebral alignment when performing manipulations. Despite the differing treatment goals, the actual procedures performed are very similar. Further, any distinction is questionable because of evidence refuting the claim that adjustments reliably restore misalignments (called vertebral subluxations by chiropractors).(Keating) The cause of problem has been identified as originating from flaws in chiropractic diagnostic regimens where the underlying causes of biomechanical problems are overlooked while the effect (misalignment) is mistakenly assumed to be the primary cause-leading to premature, inaccurate and incomplete diagnosis.(Barrett, Powell)
The most common “adjustment” employed by chiropractors is a high velocity, low amplitude (HVLA) thrust that usually causes an audible popping sound that results from nitrogen gas being released from the synovial fluid found in diarthrodial joints. When an adjustment is performed by a chiropractor, the force applied separates the joint surfaces of the fully encapsulated joint creating a relative vacuum within the joint space. In this low pressure environment, the naturally dissolved nitrogen found in all bodily fluids turns into a gas and a sound is heard. This gas bubble will remain within the joint for hours while it is slowly reabsorbed by the body. The effects of this treatment include: temporary relief of musculoskeletal pain, shortened time to recover from acute back sprains and reduction of muscle spasm.(Rand) Common side effects include: soreness from minor, treatment induced joint strains, dependency on treatment and neck hypermobility. Less frequent but more serious side effects include: stroke, herniation of intervertebral disks and rib fractures.(Senstad) Serious complications due to manipulation of the cervical spine remain rare, having been documented at 1 in 3 or 4 million manipulations or fewer. The current esitmate is based on multiple international studies of millions of chiropractic cervical adjustments spanning from present day back to at least 1965. The "one in a million" estimate is echoed in an extensive review of spinal manipulation performed by the RAND corporation. Less conservative treatments such as neck surgery are also commonly used for conditions very similar to the conditions chiropractors treat using spinal adjustments. In comparison, cervical spine surgery has a 3-4% rate of complication and 4,000-10,000 deaths per million neck surgeries.
Other types of adjustments may include thrusts from mechanical instruments, dropping tables and gentle sustained touches.(Cooperstein) Another problem is the use of elaborate analyses based on questionable rationales because of outdated, incomplete and/or overly simplified biomechanical systems which are relied on to determine the alignment of bones.(Harrison)
Examples of these adjustments include: H.I.O., Toggle, Toggle-Recoil, Palmer, Knee Chest Upper Cervical, Kale, Full Spine, Gonstead, Thompson, Drop Table, Diversified, Activator, Pierce, Pediatric adjusting, Geriatric Adjusting, Pregnancy Adjusting and Extremity Adjusting.
