AcupunctureA study appearing in the journal Rheumatology (2006 45(2):222-227) looked at the effect acupuncture had on treating 736 patients with chronic pain due to osteoarthritis of the hip or knee. The subjects filled out questionnaires to ascertain their pain level and quality of life. On average the subjects received a little over 8 acupuncture treatments. Significant improvements were seen after treatment and during a six-month follow up investigation.
