“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]”
The adjustments cause a sympathetic nervous response that produces dopamine and seratonin. They can feel great. That’s documented and undisputed. Also undisputed is that such response is enough to heal certain injuries for certain people. The placebo effect is real. If the patient believes it works, that’s enough sometimes.
The risks of chiropracty out weigh the benefits, IMO.
