Misinformation by chiropractors is unfortunately nothing new and has been discussed ad nauseam on this blog. It is tempting to ask whether chiropractors have lost (or more likely never had) the ability to ditinguish real information from misinformation or substantiated from unsubstantiated claims. During the pandemic, the phenomenon of chiropractic misinformation has become even more embarrassingly obvious, as this new article highlights.
Chiropractors made statements on social media claiming that chiropractic treatment can prevent or impact COVID-19. The rationale for these claims is that spinal manipulation can impact the nervous system and thus improve immunity. These beliefs often stem from nineteenth-century chiropractic concepts. The authors of the paper are aware of no clinically relevant scientific evidence to support such statements.
The investigators explored the internet and social media to collect examples of misinformation from Europe, North America, Australia and New Zealand regarding the impact of chiropractic treatment on immune function. They discussed the potential harm resulting from these claims and explore the role of chiropractors, teaching institutions, accrediting agencies, and legislative bodies.
The authors conclude as follows: In this search of public media in Europe, North America, New Zealand, and Australia, we discovered many cases of misinformation. Claims of chiropractic treatment improving immunity conflict with the advice from authorities and the scientific consensus. The science referenced by these claims is missing, flawed or has no clinical relevance. Consequently, their claims about clinical effectiveness are spurious at best and misleading at worst. However, our examples cannot be used to make statements about the magnitude of the problem among practitioners as our samples were not intended to be representative. For that reason, we also did not include an analysis of the arguments provided in the various postings. In view of the seriousness of the topic, it would be relevant to conduct a systematic study on a representative sample of public statements, to better understand these issues. Our search illustrates the possible danger to public health of misinformation posted on social media and the internet. This situation provides an opportunity for growth and maturation for the chiropractic profession. We hope that individual chiropractors will reflect on and improve their communication and practices. Further, we hope that the chiropractic teaching institutions, regulators, and professional organisations will always demonstrate responsible leadership in their respective domains by acting to ensure that all chiropractors understand and uphold their fiduciary duties.
Several previous papers have found similar things, e.g.: Twitter activity about SMT and immunity increased during the COVID-19 crisis. Results from this work have the potential to help policy makers and others understand the impact of SMT misinformation and devise strategies to mitigate its impact.
The pandemic has crystallised the embarrassment about chiropractic false claims. Yet, the phenomenon of chiropractors misleading the public has long been known and arguably is even more important when it relates to matters other than COVID-19. Ten years ago, we published this paper:
Background: Some chiropractors and their associations claim that chiropractic is effective for conditions that lack sound supporting evidence or scientific rationale. This study therefore sought to determine the frequency of World Wide Web claims of chiropractors and their associations to treat, asthma, headache/migraine, infant colic, colic, ear infection/earache/otitis media, neck pain, whiplash (not supported by sound evidence), and lower back pain (supported by some evidence).
Methods: A review of 200 chiropractor websites and 9 chiropractic associations’ World Wide Web claims in Australia, Canada, New Zealand, the United Kingdom, and the United States was conducted between 1 October 2008 and 26 November 2008. The outcome measure was claims (either direct or indirect) regarding the eight reviewed conditions, made in the context of chiropractic treatment.
Results: We found evidence that 190 (95%) chiropractor websites made unsubstantiated claims regarding at least one of the conditions. When colic and infant colic data were collapsed into one heading, there was evidence that 76 (38%) chiropractor websites made unsubstantiated claims about all the conditions not supported by sound evidence. Fifty-six (28%) websites and 4 of the 9 (44%) associations made claims about lower back pain, whereas 179 (90%) websites and all 9 associations made unsubstantiated claims about headache/migraine. Unsubstantiated claims were made about asthma, ear infection/earache/otitis media, neck pain,
Conclusions: The majority of chiropractors and their associations in the English-speaking world seem to make therapeutic claims that are not supported by sound evidence, whilst only 28% of chiropractor websites promote lower back pain, which is supported by some evidence. We suggest the ubiquity of the unsubstantiated claims constitutes an ethical and public health issue.
It makes it clear that the misleading information of chiropractors is a serious problem. And I find it disappointing to see that so little has been done about it, and that progress seems so ellusive.
This, of course, begs the question, where does all this misinformation come from? The authors of the new paper stated that beliefs often stem from nineteenth-century chiropractic concepts. This, I believe, is very true and it gives us an important clue. It suggests that, because it is good for business, chiro schools are still steeped in obsolete notions of pseudo- and anti-science. Thus, year after year, they seem to churn out new generations of naively willing victims of the Dunning Kruger effect.
We have often heard it said on this blog and elsewhere that chiropractors are making great strides towards reforming themselves and becoming an evidence-based profession. In view of the data cited above, this does not ring all that true, I am afraid. Is the picture that emerges not one of a profession deeply embroiled in BS with but a few fighting a lost battle to clean up the act?
