[Yoga as an intervention for chronic pain].

The use of yoga, especially as an intervention for chronic pain, is increasing worldwide. Available data on chronic low back pain, within limits also for chronic neck pain and certain types of headache, show statistically significant positive effects related to pain intensity and pain-related impairments. The data provide evidence that yoga is at least equal in efficacy and safety to other exercise interventions as well as individualized physical therapy. The dose of the intervention seems to be of secondary importance, but the establishment of a long-term independent practice after initial supervision seems to be essential; however, for other pain disorders there is still a need for research.
