Medical risks of spinal manipulation
According to the National Council Against Health Fraud, the conviction held by chiropractic believers that every spine will benefit from an adjustment causes them to manipulate spines inappropriately. Among the concerns about chiropractic manipulation is the widespread use of the explosive "dynamic thrust" which takes the patient by surprise, as opposed to more conservative techniques. This maneuver has a greater potential for inflicting injury.
The practice of greatest concern is the rotary neck movement (sometimes called "Vaster cervical'' or "rotary break"). This type of manipulation has led to trauma, paralysis, strokes, and death among patents. Even chiropractic's legal advisors have warned against its use.
The overuse of x-ray by chiropractors poses potential patient harm. Of primary concern is the 24' x 36' full spine x-ray. This technique exposes patients to a substantial amount of radiation. Exposing the body trunk to x-rays can have serious long-range consequences and should be avoided. Further, according to NCAHF's chiropractic advisors, such radiographs have little or no diagnostic value.
Criticism of chiropractic claims
The National Council Against Health Fraud, an American private, non-profit health care organization issued a report in 1985 critical of chiropractic medicine.
Sixty-two clinical neurologists from across Canada, all certified members of the Royal College of Physicians and Surgeons, have issued a warning to the Canadian public and provincial governments about the dangers of neck manipulation. [1]
Mainstream medical doctors and scientists reject the claims of most chiropractic associations and schools as pseudoscience; many refer to their claims as fraud. Recently, however, a chiropracter from the Canadian Memorial Chiropractic College, in Toronto, and two professors at the Los Angeles College of Chiropractic also came to this position; they hold that all chiropractic organizations engage in and promote "quackery".
York University at one point attempted to affiliate with a chiropractic school. The scientists and medical doctors at this school rebelled against the plan, and even created their own website explaining why this would be a bad idea. They enlisted the help of Nobel prize-winning scientists to explain to the school's administration, and public-at-large, why chiropractice is unscientific. [1]
There are many investigations and lawsuits underway in Canada for false advertising, deceptive practices and claims, injuries and deaths.
Misuse of science reports
Some doctors who have submitted research backing up the medical benefits of limited forms of spinal maipulation have found their claims incorrectly applied to the entire field of chiropractic manipulation. Perhaps the most well-known case of this occurred in response to The RAND report on The Appropriateness of Spinal Manipulation for Lower-Back Pain. This scientific study was a meta-analysis of 22 controlled experiments; the conclusion was that certain forms of spinal manipulation were successful in treating certain types of lower-back pain. Many chiropractors seized upon these results as proof that chiropractic theory was sound and that chiropractic medicine had reliable results; in fact, the authors of the report had said no such thing. Misuse of this report reached such an extent that the RAND report authors were forced to issue a public statement. In 1993 Dr. Paul Shekelle rebuked the chiropractic industry for making false claims about RAND's research:
- "...we have become aware of numerous instances where our results have been seriously misrepresented by chiropractors writing for their local paper or writing letters to the editor....RAND's studies were about spinal manipulation, not chiropractic, and dealt with appropriateness, which is a measure of net benefit and harms. Comparative efficacy of chiropractic and other treatments was not explicitly dealt with."
