“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]”
This is the entire problem with quackocrackers, they have no ability to diagnose any illness or disease. So people who think they just have a back ache and go to a quackcracker instead of a real dodctor are delaying getting a proper diagnosis, so then if they happen to have something more serious like cancer, they’ll essentially be sacrificing their own life by going to quackocracker instead of finding out whats really wrong.
