“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]”
Chiropractic has its benefits. The problem is that you can’t make a living if all you are doing is the few things that chiropractic works for. That’s why they have to make all kinds of spectacular claims about the benefits and rope you into 6 months of twice a week visits.
The Dr I went to as a kid was an MD and had a chiropractic license. He was able to reset my rib when it got knocked out from being shoved between the seats on the school bus.
