Most chiropractors claim that their manipulations prevent illness, not just spinal but also non-spinal conditions. But is there any sound evidence for that assumption? A team of chiropractic researchers wanted to find out. Specifically, the objective of their systematic review was to investigate if there is any evidence that spinal manipulations/chiropractic care can be used in primary prevention (PP) and/or early secondary prevention in diseases other than musculoskeletal conditions.
Of the 13.099 titles scrutinized by the authors, 13 articles were included. These were
- 8 clinical studies,
- 5 population studies.
These studies dealt with various issues such as
- diastolic blood pressure,
- blood test immunological markers,
- and mortality.
Only two clinical studies could be used for data synthesis. None showed any effect of spinal manipulation/chiropractic treatment.
The authors’ conclusions were straight forward: we found no evidence in the literature of an effect of chiropractic treatment in the scope of PP or early secondary prevention for disease in general. Chiropractors have to assume their role as evidence-based clinicians and the leaders of the profession must accept that it is harmful to the profession to imply a public health importance in relation to the prevention of such diseases through manipulative therapy/chiropractic treatment.
Many chiropractors have adopted the ‘dental model’ in their practice, proposing to prevent all sorts of conditions through treatment of spinal subluxations before symptoms arise. Some call this approach ‘maintenance care’ and liken it to the need for servicing a car. They tell their patients that regular consultations will prevent problems in the future. It seems obvious that this can be a nice little earner. In 2009, I reviewed the evidence on chiropractic maintenance treatment. Here is the abstract:
Most chiropractors advise patients to have regular maintenance treatments with spinal manipulation, even in the absence of any symptoms or diseases. This article evaluates the evidence for or against this approach. No compelling evidence was found to indicate that chiropractic maintenance therapy effectively prevents symptoms or diseases. As spinal manipulation has repeatedly been associated with considerable harm, the risk benefit balance of chiropractic maintenance care is not demonstrably positive. Therefore there are no good reasons to recommend it.
The new review confirms that this approach is useful only for filling the pockets of chiropractors.
The inevitable question arises: WHEN WILL CHIROPRACTORS STOP MISLEADING THE PUBLIC FOR THEIR PERSONAL GAIN?
