Title: Efficacy of Acupuncture Therapy Versus Sham Acupuncture on Knee Osteoarthritis: a Randomized Controlled Trial
Brief Summary: Knee osteoarthritis (KOA), also called degenerative knee disease, is one of the most common bone and joint diseases in clinic. It was estimated to affect more than 9 million individuals in the United States in 2005 and is a leading cause of disability and medical costs. Most elderly people over the age of 65 have radiographic and/or clinical evidence of osteoarthritis. KOA is a lifelong disease which can lead to obvious pain, joint stiffness, limitation of activity and even joint failure or disability. Acupuncture is a popular treatment taken from ancient Chinese medicine, in which fine needles are placed into the body at specific points. Studies have shown that acupuncture can stimulate nerves under the skin, causing the body to produce natural pain-relieving substances (endorphins). However the evidences of acupuncture for KOA are contradictory. According to the review, intensive acupuncture with three sessions a week is more effective for KOA than sparse acupuncture with one session a week. Moreover, the papers published in the past years suggest that manual acupuncture and electro-acupuncture are most commonly used acupuncture therapy for the treatment of knee osteoarthritis. The aim of this study is to evaluate the efficacy of intensive electro-acupuncture or manual acupuncture versus sham acupuncture in reducing pain and improving function in patients with KOA.
