Fresh science! And bad news: clearly negative results from a good quality test of the efficacy of three months of regular chiropractic therapy for migraine, with follow-up for a year afterwards. Over one hundred patients received spinal manipulative therapy (SMT), a sham, or just their standard meds. Spinal manipulation for migraine was no better than the sham by any measure. On two secondary outcomes, it was trivially better than the control group only (not the sham), but too little to care. Therefore, the authors reasonably concluded that “the effect of chiropractic spinal manipulative therapy observed in our study is probably due to a placebo response.”
The full summary has about 3× more detail: see Chaibi 2016. Articles updated with this citation: • Does Spinal Manipulation Work? • The Complete Guide to Chronic Tension Headaches • The Complete Guide to Neck Pain & Cricks
