[Acupuncture in the treatment of locomotive disorders - status of research and situation regarding clinical application].

Acupuncture has been used for over 2000 years for a wide variety of complaints with minimal side effects. Based on the experience in Chinese medicine and the anticipated positive effects, acupuncture has been widely accepted in Western medicine as well. Some clinical evidence supports the efficacy of acupuncture treatment, but randomized controlled trials have been conducted for only a few of all possible locomotive disorder indications, and the results have been equivocal. Other indications have not yet been systematically studied, and application is based on clinical experience and consensus among practitioners. One of the outcomes on which consensus appears to exist is that 10-20 sessions are generally necessary, and that initial improvement can be expected to occur by the 10th treatment. Rigorous trials should be conducted to improve clinical validity and provide scientific proof of the efficacy of acupuncture. Clinical trials like the German Acupuncture Trials (gerac), funded by the German health insurance companies, have been launched with the aim of furthering knowledge in this area.
