This survey investigated how many chiropractors in the Canadian province of Alberta promote a theory of subluxation, which health ailments or improvements were linked to subluxation, and whether the subluxation discourse was used to promote chiropractic for particular demographics.
Using the search engine on the Canadian Chiropractic Associations’ website, the researchers made a list of all clinics in Alberta. They then used Google searches to obtain a URL for each clinic with a website, totalling 324 URLs for 369 clinics. They then searched on each website for “subluxation” and performed content analysis on the related content.
One hundred twenty-one clinics’ websites (33%) presented a theory of vertebral subluxation. The ailments and improvements discussed in relation to subluxation were wide-ranging; they included the following:
- back pain,
- bed wetting
- blood pressure,
- ear infection,
- heart disease,
- hormonal imbalance,
- learning problems,
- menstrual cramps,
- Parkinson’s disease,
- problems with hearing,
- problems with vision,
- prostate cancer,
- respiratory disease,
- sleeping problems,
- spinal decay,
- sudden infant death syndrome,
- and many more.
The marketing of chiropractic for children was observed on 8% of the clinic websites.
The researchers concluded that, based on the controversy surrounding vertebral subluxation, the substantial number of clinic websites aligning their practice with vertebral subluxation should cause concern for regulatory bodies.
Why do so many chiropractors cling so tightly to the long obsolete concept of subluxation? The way I see it there are at least three reasons:
- If they abandoned subluxation, they would quickly become physiotherapists, only with a much reduced scope of practice.
- Using the subluxation myth avoids the need of the knowledge of any complicated pathophysiology.
- Subluxation is ever so good for business, as it renders chiropractic manipulation a cure all.
D. D. Palmer, the magnetic healer who invented chiropractic about 120 years ago, claimed that a vital energy, which he called the “innate”, controls all body functions. In the presence of “vertebral subluxation,” it cannot work adequately, he postulated. In other words, subluxations block the flow of the innate which, in turn, is the cause of all disease. Palmer therefore developed spinal manipulations to correct such subluxations and de-block the flow of the innate. Palmer defined chiropractic as a system of healing based on the premise that the body requires unobstructed flow through the nervous system of innate intelligence. This effectively makes the adjustment of subluxation a panacea.
To put it simply: subluxation is the carte blanche required for making unlimited bogus claims, while ripping off the public.
