“Systematic reviews of controlled clinical studies of treatments used by chiropractors have found no evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain.[8] A 2011 critical evaluation of 45 systematic reviews concluded that the data included in the study “fail[ed] to demonstrate convincingly that spinal manipulation is an effective intervention for any condition.”[10] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain, but the results for acute low back pain were insufficient.[11] No compelling evidence exists to indicate that maintenance chiropractic care adequately prevents symptoms or diseases.[12]”
Chiropractors and osteopaths only exist in such large numbers because they bill less to insurers than actual doctors & hospitals. So of course insurers are going to promote these quacks because it’s cheaper than somebody going to an actual physiotherapist for treatment.
There should really be legislation that requires insurers to cover science & evidence based treatments. If someone wants woo it should be at additional expense to them, not part of a standard policy.
