There is limited evidence to suggest it may be effective for some types of neck, shoulder or lower limb pain and recovery after hip or knee operations.
There is no good evidence that osteopathy is effective as a treatment for health conditions unrelated to the musculoskeletal system (bones and muscles).
Evidence is limited because the profession is in need of more comprehensive research to be done, but that there is little or no funding available, research is slow.
However, in a lot of countries osteopathy is recognised and well accepted by the medical profession and supported by health insurance companies as it has been recognised as helping to reduce days of work lost due to muscle-skeletal pain.
