The Webster Technique: B.C.'s Chiropractic Regulator Banned a Popular Breech-Baby Claim Before a Single Public Complaint
The Webster Technique is marketed to pregnant women across Canada as a gentle chiropractic method that can help turn a breech baby and ease labour. British Columbia's chiropractic college concluded the evidence didn't support any of it — and banned the marketing outright in 2019, proactively, without waiting for a patient complaint. Chiropractors elsewhere continue advertising it in the same terms the B.C. college specifically prohibited.
What the Webster Technique claims to do
Developed by chiropractor Larry Webster in the 1980s and promoted through the International Chiropractic Pediatric Association (ICPA), which he founded, the Webster Technique is a specific sacral adjustment marketed as relieving "intrauterine constraint" — a term chiropractic proponents use to describe musculoskeletal tension they claim restricts fetal movement and can cause a baby to settle into a breech (feet- or bottom-first) position. Marketing for the technique commonly claims it can help turn a breech baby, shorten labour, reduce the need for cesarean section, and even affect a mother's hormone function or risk of postpartum depression.
⚠️ The evidence behind these claims is thin
The most frequently cited support for the Webster Technique's breech-turning claim is a 2002 survey of ICPA member chiropractors reporting an 82% success rate — an uncontrolled, self-reported survey of practitioners with a direct professional interest in the technique's reputation, not a clinical trial. Wikipedia's summary of the available research states plainly that studies on the technique are minimal in number and weak in conclusion. No properly controlled trial has demonstrated that the Webster Technique changes fetal position at a rate better than the roughly one in ten breech babies who turn spontaneously without any intervention at all.
British Columbia's regulator acted on its own initiative
A proactive crackdown, not a reactive one
In December 2019, the College of Chiropractors of B.C. (CCBC) amended its Professional Conduct Handbook and Efficacy Claims Policy to specifically prohibit Webster Technique marketing. Registrants were barred from claiming chiropractic care has any beneficial effect on fetal development or position — including breech turning, breech position, or "intrauterine constraint" — any beneficial effect on labour or birth, including easier or shorter labour or avoiding medical intervention, or any beneficial effect on hormone function or postpartum depression. The college gave practitioners until January 30, 2020 to update their marketing or face investigation and possible discipline. Notably, the college's registrar told CBC News the policy update was not prompted by any public complaint — the college said it was acting proactively on its own concerns about the state of the evidence.
The Webster Technique may now only be advertised in B.C. as "a specific chiropractic sacral analysis and diversified adjustment for all weight-bearing individuals" — with no reference to pregnancy, breech position, or birth outcomes at all. This followed an earlier 2018 CCBC policy that similarly barred chiropractors from claiming to treat conditions like autism and cancer, part of a broader pattern of the same regulator repeatedly having to intervene on unsupported efficacy claims.
How the college checked whether it worked
Unusually for a Canadian health regulator, the CCBC's follow-through has itself been studied. A 2020 paper in Chiropractic & Manual Therapies examined how the college used internet analytics — systematically monitoring registrants' websites and social media — to evaluate and remediate ongoing violations of the pregnancy and COVID-19 efficacy claims policies, rather than relying solely on the traditional complaints-driven model most Canadian health colleges use.
The claims persist elsewhere
Outside B.C.'s specific policy, Webster Technique marketing using exactly the language the CCBC prohibited remains common. Clinic websites continue to describe the technique as helping a baby "turn on his/her own" by relieving pelvic constraint, and cite the same uncontrolled 2002 practitioner survey as evidence of an "82 percent success rate" — the same figure B.C.'s regulator concluded did not meet the bar for a public efficacy claim.
Why this belongs on QuackeryWatch
This is a genuinely encouraging Canadian regulatory story, and worth documenting for that reason as much as any other: a college that got ahead of a popular, emotionally resonant claim — marketed to pregnant women worried about a difficult birth — before a single complaint forced its hand, and then built a monitoring system to check its own policy actually changed behaviour. It sits alongside the pediatric chiropractic survey already documented in our Pediatric Quackery section, which flagged the same underlying "subluxation" framework being applied, with equally thin evidence, to conditions from infant colic to childhood ADHD.
