Chiropractors are getting very touchy indeed, all over the world. And no wonder, because their claims are being exposed as baseless as never before, in the wake of their attempts to stifle criticism by legal action..
In March, Shaun Holt appeared on Breakfast TV in New Zealand. Holt has done a lot of good work on TV in debunking some of the preposterous claims made by quacks. See him on YouTube.
This time he talked about chiropractic. Here is the video.
One could argue that he was over generous to chiropractic, especially when talking about their effectiveness in treating low back pain. He said, quite rightly, that chiropractors are no better than physiotherapists at treating low back pain.
But a recent trial suggests that neither are much good. “A randomised controlled trial of spinal manipulative therapy in acute low back pain” (Juni et al., 2009 in the BMJ; see also coverage in Pulse). This trial compared standard care with standard care plus spinal manipulative therapy (SMT). The results were negative, despite the fact that this sort of A + B vs B design is inherently biassed in favour of the treatment (see A trial design that generates only ”positive” results, Ernst & Lee 2008, Postgrad Med J.).
"SMT was performed by a specialist in manual medicine, chiropractice and rheumatology (GH), a specialist in physical medicine (DV) or an osteopath (RvB), all proficient in SMT."
"Conclusions: SMT is unlikely to result in relevant early pain reduction in patients with acute low back pain."
Admittedly, the trial was quite small (104 patients, 52 in each group) so it will need to be confirmed. but the result is entirely in line with what we knew already.
It also adds to the evidence that the recommendation by NICE of SMT by chiropractors constitutes their biggest failure ever to assess evidence properly. If NICE don’t amend this advice soon, they are in danger of damaging their hitherto excellent record.
Despite the moderate tone and accuracy of what Holt said on TV, the New Zealand Chiropractors’ Association made a formal complaint. That is what they like to do, as I learned recently, to my cost. It is so much easier than producing evidence.
Quite absurdly the New Zealand Broadcasting Standards Authority (BSA) has upheld some of the complaints. Their judgement can be read here.
The BSA consists of four people, two lawyers and two journalists. So not a trace of scientific expertise among them. Having people like that judging the claims of chiropractors makes as much sense as having them judged by Mr Justice Eady. They seem to be the sort of people who think that if there is a disagreement, the truth must lie half-way between the opposing views.
One of the BSA members, Tapu Misa, has used her newspaper column to quote approvingly the views of the notorious Dr Mercola web site on flu prevention “Your best defence, it says, is to eat right, get lots of sleep, avoid sugar and stress, load up on garlic, Vitamin D and krill oil”. (Snake oil is said to be good too.) There are some odd attitudes to science in some of her other columns too (e.g. here and here). Not quite the person to be judging the evidence for and against chiropractic, I think.
In fact the TV show in question was more than fair to chiropractors. It adopted the media’s usual interpretation of fair and balanced: equal time for the flat earthers. A Chiropractor was invited to reply to Holt’s piece. Here he is.
The chiropractor, Doug Blackbourn, started very plausibly, though a tendency to omit every third syllable made transcription hard work. He established that if you cut yourself you get better (without any help). He established that nerves run down the spinal cord. So far, so good. But then he quickly moved on to the usual flights of fancy.
"We have two premises. The body heals itself and the nervous system runs the body. Now the nervous system runs the body, travels down through the spinal cord so chiropractic is not based on the belief that, you know, energy flows, it’s based on the fact that your nervous system runs the body and [inaudible] affects the overall health of the body"
This statement is totally vague. It has nothing whatsoever to do with the main question, can chiropractors do anything useful. It is sheer flannel.
We’re seeing people, heck, diabetes. I had a quadriplegic come in one time for adjustment, we’ve got stroke people, we’ve got all sorts of conditions. We’re not treating the condition, We’re allowing, checking the spine to see if there’s any interference there that will slow the body down"
“Interference”? “slowing the body down”? These are utterly meaningless phrases that simply serve to distract from the only question that matters.
"Chiropractice is the most safest [sic] profession to go to to get your spine adjusted"
Hmm I thought it was the only job that uses the word ‘adjustment’.
Worst of all was his response to a question about asthma.
Presenter: "So chiropractors are not out there claiming they will cure asthma for example?". Chiropractor: "No"
This is simply untrue, both in New Zealand and in the UK. For a start, just look at what Blackbourn’s own web site says about asthma.
"The challenge, of course, with allergy and asthma medication is there is no end-point. There is no cure. Asthma and allergies, for the most part, are lifelong conditions requiring lifelong medication. Might there be a better way, an alternative solution?
“Alternative” is the key word. Medical treatment is designed to combat symptoms, and is successful to a certain extent with allergies and asthma. Underlying causes are not addressed, however, and symptoms continue year after year. What else might be done?
Enter chiropractic care. Chiropractic health care, with its unique comprehensive approach, is able to offer positive benefit to a variety of conditions and ailments. In the case of allergies and asthma, these “hypersensitivity conditions” may respond well to therapy designed to normalize the body’s flow of nerve signals. To use a metaphor, chiropractic treatment removes roadblocks to the body’s natural healing abilities. Restoring these imbalances may help reduce such hypersensitivity reactions."
Blackbourn’s web site describes him thus
"As a Doctor of Chiropractic, Dr. Doug Blackbourn . . ."
But the qualifications of “Dr” Blackbourn are B.App.Sc (Chiro) M.N.Z.C.A , the same as those of “Dr” Brian Kelly.
After a performance like this, perhaps someone should submit a complaint to the New Zealand Broadcasting Standards Authority.
After all, I notice that they have dismissed complaints from one chiropractor, Sean Parker, after a TV programme looked at the business practices of his private chiropractic practice, The Spinal Health Foundation. Perhaps the BSA understands business better than it understands science.
Is chiropractic crumbling in New Zealand? The New Zealand College of Chiropractic featured in my editorial in the New Zealand Medical Journal, and in the fallout from that article, It’s principle, “Dr” Brian Kelly (B App Sci (Chiro)) seems to be getting desperate. His college is now canvassing for recruits in Canada. They are promised all the woo.
- Subluxation centered techniques – Gonstead, Toggle Recoil, Thompson, Diversified
- Traditional philosophy featuring vitalism and innate healing – congruent curriculum
Perhaps Canada is a good place to recruit, gven the $500 million class action being brought against chiropractors in Canada, after Sandra Nette became tetraplegic immediately after a chiropractor manipulated her neck, Canadian chiropractors must be looking for somewhere to hide.
