Compared to most medical treatments, few interventions can initiate back pain relief and healing like chiropractic adjustments can. The European Spine Journal published findings from a clinical trial uncovering how chiropractic adjustments resulted in a 72 percent success rate in treating sciatica-related symptoms. This can be compared to a 20 percent success rate from treatment with physical therapy, and a 50 percent success rate from corticosteroid injections. Another randomized, double-blind trial published in the Spine Journal comparing active versus simulated chiropractic manipulations on patients with sciatic nerve pain who were residing in rehabilitation medical centers found that active manipulations had more effect than simulated manipulations. Active manipulations reduced the number of days patients experienced moderate or severe back pain and other sciatica symptoms, and also caused no reported adverse effects. [Link to Source]
