Just noticed this on Stephen Barrett's on-line Quackwatch newsletter: "Review questions spinal manipulative therapy. A comprehensive review has concluded that spinal manipulative therapy (SMT) is no more effective for acute low back pain than inert interventions, sham SMT. or as adjunct therapy, and also seems to be no better than other recommended therapies. The reviewers looked at 20 randomized controlled trials with a total of 2,674 participants. The studies varied greatly in quality and contained very little data on recovery, return-to-work, quality of life, or costs of care. [Rubinstein SM and others. Spinal manipulative therapy for acute low back pain: An update of the Cochrane Review. Spine 38:E158-E177, 2013]" Here's the link: http://www.ncbi.nlm.nih.gov/pubmed/23169072 Of course, this review just echoes previous findings and confirms what Dr Sarno has been saying for years. Certainly sounds as though chiropractic cures and the placebo effect are one and the same.
