The UK’s ruling body for chiropractors, the General Chiropractic Council (GCC), has declared the same claims that the British Chiropractic Association (BCA) have charged science writer Simon Singh as falsely claiming as ’bogus’ are contrary to evidence. Or, some would say, actually bogus.
According to the GCC’s ’What is the GCC’ page, ’it is a criminal offence for anyone to describe themselves as any sort of chiropractor [in the UK] without being registered with the GCC’ and that one of their aims is to ’set the standards of chiropractic education, conduct and practice’ (my emphasis).
I’m no lawyer, but on the face of it the BCA have two obvious choices: pull out of the libel case against Simon Singh as a consequence of the GCC’s findings, or part ranks with the GCC and sue their own ruling body in order to be consistent with continuing with their suit against Simon Singh.
Although (highly) unlikely, particularly as they are almost certainly legally obligated to work within the constraints of the GCC, the latter option would be an entertaining dog fight.
The news of the GCC’s findings originate from an article from the Guardian by Martin Robbins that scibling Alison Campbell emailed me and earlier reported earlier tonight. In his article, Robbins claims that an up-shot of the law suit against Simon Singh is that:
A staggering one in four chiropractors in Britain are now under investigation for allegedly making misleading claims in advertisements, according to figures from the General Chiropractic Council.
The details for the interested are in Robbins’ article, but the essence is that the BCA is swamped with claims and it’s costing them.
I’d like to draw readers attention to these two paragraphs near the end of Robbins’ article:
Now even the General Chiropractic Council has disowned the claims of the BCA — the same claims that lie at the centre of its libel action against Simon Singh.
In a new report, it has attempted to clarify the assertions that chiropractors can and cannot make, backed up by a systematic review of the evidence. Notably, the report concludes that the evidence does not support claims that chiropractic treatment is effective for childhood colic, bed-wetting, ear infections or asthma, the very claims that Singh was sued for describing as “bogus”.
At most readers would realise, the ruling body has undermined the British association’s case. As far as I can see, they’ve obliterated it.
The article referred to, by Bronfort and colleagues, is available on-line (PDF file) for those who wish to draw their own conclusions. I would suggest, though, that you first read the original evidence which examines these claims that Alison Campbell has listed in her blog article. (The short article by Ernst is particularly worth reading and, I feel, may be easier for many to follow.)
Bronfort and colleagues summarise their findings in several tables, by region of body or symptom: spinal, extremity, headache or ’other’, non-musculoskeletal, noting the kind of intervention tested. Claims tested are listed by level of evidence–high, moderate, or inconclusive–and the outcome the nature of the evidence: positive, favourable, inconclusive or negative.
Evidence that is inconclusive or negative cannot be used to support a claim.
From their tables, symptoms that they list as having inconclusive or negative evidence for treatment by any of the treatments examined are:
Asthma, Colic, Otitis media, Nocturnal Enuresis, Premenstrual syndrome, Hypertension, Pneumonia in Older Adults, Fibromyalgia, Myofascial Pain Syndrome, Miscellaneous Headache, Morton’s Neuroma, Hallux Limitus, Hallux Abducto Valgus, Ankle Sprains or fractures, Knee Arthroplasty Rehabilitation, Hip Arthroplasty Rehabilitation, Carpal Tunnel Syndrome, Rotator Cuff Pain, Shoulder Pain, Sciatica / Radiating Leg Pain, Coccydynia, Mid Back Pain
The GCC rejects many of the claims many of it’s practitioners make, including the very claims that the BCA have objected to Simon Singh objecting to.
The only treatment they report as showing positive support at a high level of evidence was treatment for chronic low back pain using spinal manipulation /mobilization.
They offer mixed ‘moderate’ support for other spinal conditions: some have ‘moderate’ support under some treatment regimes, but are inconclusive under other treatment regimes.
Other, non-spinal, symptoms are listed as having ‘moderate’ support under particular treatment regimes. (The full list is too long to re-iterate here: interested readers can read them in the PDF copy of the article linked earlier.)
The authors point out that the ‘moderate’ standard of evidence is limited by:
- The number, size, or quality of individual studies.
- Inconsistency of findings across individual studies.
- Limited generalizability of findings to routine practice.
- Lack of coherence in the chain of evidence.
They conclude their description of the ‘moderate’ standard of evidence, stating:
As more information becomes available, the magnitude or direction of the observed effect could change, and this change may be large enough to alter the conclusion.
As such, ‘moderate’ support should be taken as tentative. With this in mind, the only tested treatment by chiropractic with full evidential support according to their study is treatment of chronic low back pain.
A key concept here is that treatments offered should be based on claims that can be substantiated, as also lies at the heart of the issue with other remedies such as homoeopathy and ’treatments’ for autism based on unsound ideas.
It will be interesting to watch the impact has on the BCA’s libel case against Simon Singh and if the public exposure of these unsupported remedies encourages people to move on to sounder practice. Let’s hope so.
