Another randomized 3-arm study was conducted to assess the efficacy and safety of traditional Chinese acupuncture compared with sham acupuncture (needling at defined non-acupuncture points) and conservative therapy in patients with chronic pain due to osteoarthritis of the knee. Addition of acupuncture led to significant improvement in the symptoms (27). Recently, Dickman et al evaluated the efficacy of adding acupuncture (twice a week over 4 weeks) as compared to doubling the PPI dose in 30 refractory GERD patients(28). The acupuncture group demonstrated a significant decrease in mean daytime heartburn scores compared to high-dose PPI group. Mean nighttime heartburn and regurgitation scores improved only in the acupuncture group. Thus this study showed that adding acupuncture as compared to doubling the PPI dose was more effective in controlling symptoms of GERD in patients on standard dose of PPI.
