An international team of authors has concluded that evidence from a variety of moderate quality randomised controlled trials, suggests acupuncture is effective for treating the pain of tennis elbow. They studied 19 trials, conducted in Germany, Canada, Italy and China, which compared acupuncture and/or moxibustion with such other approaches as sham acupuncture or conventional treatment (eg steroid injection, non-steroidal anti-inflammatory drugs, ultrasound). The authors suggest that the results justify further trials of rigorous design.
