"More than 20 million Americans have osteoarthritis. This disease is one of the most frequent causes of physical disability among adults," said Stephen I. Katz, M.D., Ph.D., NIAMS Director. "Thus, seeking an effective means of decreasing osteoarthritis pain and increasing function is of critical importance."
During the course of the study, led by Brian M. Berman, M.D., Director of the Center for Integrative Medicine and Professor of Family Medicine at the University of Maryland School of Medicine, Baltimore, Maryland, 190 patients received true acupuncture and 191 patients received sham acupuncture for 24 treatment sessions over 26 weeks. Sham acupuncture is a procedure designed to prevent patients from being able to detect if needles are actually inserted at treatment points.
In both the sham and true acupuncture procedures, a screen prevented patients from seeing the knee treatment area and learning which treatment they received. In the education control group, 189 participants attended six, 2-hour group sessions over 12 weeks based on the Arthritis Foundation's Arthritis Self-Help Course, a proven, effective model.
On joining the study, patients' pain and knee function were assessed using standard arthritis research survey instruments and measurement tools, such as the Western Ontario McMasters Osteoarthritis Index (WOMAC). Patients' progress was assessed at 4, 8, 14, and 26 weeks. By week 8, participants receiving acupuncture were showing a significant increase in function and by week 14 a significant decrease in pain, compared with the sham and control groups. These results, shown by declining scores on the WOMAC index, held through week 26. Overall, those who received acupuncture had a 40 percent decrease in pain and a nearly 40 percent improvement in function compared to baseline assessments.
