IMS helps to reduce pain and dysfunction by inserting a needle into targeted areas of tightness and trigger points in muscle tissue.  The needle produces a reflex response causing relaxation of the muscle, thus reducing tension on other joint structures.  IMS is a specialized form of needling different from acupuncture and specific training is required to perform it.  Not all patients are appropriate for IMS and thus a special assessment is done to determine if it is appropriate for you.
