In 2008, the British Chiropractic Association sued Simon Singh because he disclosed that they were promoting chiropractic for infant colic. The BCA lost the case, plenty of money, and all its reputation. Ever since the issue is a very sore point for chiropractic pride. The data show that Simon was quite correct in stating that they are happily promoting bogus treatments without a jot of evidence. Here for instance is my systematic review:

Some chiropractors claim that spinal manipulation is an effective treatment for infant colic. This systematic review was aimed at evaluating the evidence for this claim. Four databases were searched and three randomised clinical trials met all the inclusion criteria. The totality of this evidence fails to demonstrate the effectiveness of this treatment. It is concluded that the above claim is not based on convincing data from rigorous clinical trials.

But chiropractors steadfastly refuse to accept defeat and keep on trying to find positive results. Now Danish chiropractors have made another attempt.

The purpose of this study is to evaluate the effect of chiropractic care on infantile colic. This multicenter, single-blind randomized controlled trial was conducted in four Danish chiropractic clinics, 2015–2019. Information was distributed in the maternity wards and by maternal and child health nurses. Children aged 2–14 weeks with unexplained excessive crying were recruited through home visits and randomized (1:1) to either chiropractic care or control group. Both groups attended the chiropractic clinic twice a week for 2 weeks. The intervention group received chiropractic care, while the control group was not treated. The parents were not present in the treatment room and unaware of their child’s allocation.

The primary outcome was change in daily hours of crying before and after treatment. Secondary outcomes were changes in hours of sleep, hours being awake and content, gastrointestinal symptoms, colic status and satisfaction. All outcomes were based on parental diaries and a final questionnaire.

Of 200 recruited children, 185 completed the trial (treatment group n = 96; control group n = 89). Duration of crying in the treatment group was reduced by 1.5 h compared with 1 h in the control group (mean difference − 0.6, 95% CI − 1.1 to − 0.1; P = 0.026), but when adjusted for baseline hours of crying, age, and chiropractic clinic, the difference was not significant (P = 0.066). The proportion obtaining a clinically important reduction of 1 h of crying was 63% in the treatment group and 47% in the control group (p = 0.037), and NNT was 6.5. We found no effect on any of the secondary outcomes.

The authors concluded that excessive crying was reduced by half an hour in favor of the group receiving chiropractic care compared with the control group, but not at a statistically significant level after adjustments. From a clinical perspective, the mean difference between the groups was small, but there were large individual differences, which emphasizes the need to investigate if subgroups of children, e.g. those with musculoskeletal problems, benefit more than others from chiropractic care.

This seems to be a rigorous trial. However, I don’t quite understand why the authors even mention that, before adjusting, the results seemed to favor chiropractic. This only makes a squarely negative study look positive! Why would anyone want to do that? Could this perhaps hint at a reason for this odd behavior? “The study was primarily funded by the Foundation for Chiropractic Research and Postgraduate Education.”

  • The UK regulator protects chiropractors who treat children. Their own code of practice says they must work within their competences. Treating children is outside their competence.

  • but shouldn’t everybody be asking the question – where is the plausibility in all of this?

    what possible reason is there to expect that by manipulating the spine of an infant one might treat “colic” an ill-defined disorder of undetermined aetiology and really more a collection of symptoms and signs. There is not the slightest plausibility in the magical thinking notion that somehow manipulating the spine would have the remotest chance of improving this condition so the very idea is stupid from the get-go. But then so is the whole of chiropractic.

    Why do these morons persist in their idiotic belief that by manipulating the spine they can cure all manner of human ills?
    There is no rational, logical or empirical reason for this belief. It is nothing but sheer stupidity and anyone with half a brain would have abandoned it long ago. The fact that chiros persist in this magical thinking is simply more evidence (if more were needed) of their thoroughly pseudoscientific approach to life and their insistence on trying to bilk patients by any means possible and keep their income stream as lucrative as possible even if this means outright fraud.

    Chiros have no business treating children for any condition at all. They have neither the training nor the expertise and there are no conditions in this age group amenable to the maladministrations of a chiro. It is outright deception and fraud.

  • EE…Why would anyone want to do that?

    Not uncommon to report results pre and post adjusting.

    • not uncommon to make a negative study look positive?

      • They made it clear. You’re just nit picking to nit pick.

        “However, the difference did not remain statistically significant when adjusted for baseline hours of crying (P = 0.053) as well as age and chiropractic clinic (P = 0.066).”

  • Some researchers in alternative medicine are actually honest and upright. Like norwegian physician Holger Skjeie who set out to prove acupuncture for infantile colic but ended up disproving it.
