IMS involves the insertion of thin (acupuncture like) needles to find and treat muscle shortening. It is based on anatomy and neurophysiology and is different from acupuncture. IMS can be used to successfully treat a variety of conditions and pain caused by nerve dysfunction. It is a total system for the diagnosis and treatment of myofascial pain syndromes. IMS is an effective treatment choice for chronic pain, pain originating from "super-sensitive" nerves and many other conditions involving the musculoskeletal system.
