In China, a February 2013 study conducted by the Clinical Journal of Pain concluded that low back pain, the most common musculoskeletal problem, can be relieved by acupuncture with little to no adverse side effects. 

In a systematic review published by Spine Journal, acupuncture has been shown to have significantly favorable effects on chronic low back pain. In the systematic review, 32 different studies were compared, and 25 of those studies provided relevant data to come to this conclusion. Actual acupuncture treatments were compared with sham acupuncture treatments throughout the study in order to obtain the results.
