Intramuscular Stimulation (IMS) is a total system for the diagnosis and treatment of myofascial pain syndromes (chronic pain conditions that occur in the musculoskeletal system when there is no obvious sign of injury or inflammation). IMS is grounded in Western Medical Science, and has a solid foundation in its radiculopathic model of pain, which is now supported by many experts in the field. The treatment involves dry needling of affected areas of the body without injecting any substance and specifically targets injured muscles that have contracted and become shortened from distress.
The needle sites can be at the epicenter of taut, tender muscle bands, or they can be near the spine where the nerve root may have become irritated and super-sensitive. Penetration of a normal muscle is painless; however, a shortened, super-sensitive muscle will ‘grasp’ the needle in what can be described as a cramping sensation. The result is threefold. One, a stretch receptor in the muscle is stimulated, producing a reflex relaxation (lengthening). Two, the needle also causes a small injury that draws blood to the area, initiating the natural healing process. Three, the treatment creates an electrical potential in the muscle to make the nerve function normally again. The needle used in IMS, by stimulating muscle spindles, essentially becomes a specific and unique tool for the diagnosis of Neuropathic Muscle Pain.
The goal of treatment is to release muscle shortening, which presses on and irritates the nerve. Supersensitive areas can be desensitized, and the persistent pull of shortened muscles can be released. IMS is very effective for releasing shortened muscles under contracture, thereby causing mechanical pain from muscle pull. IMS, in effect, treats the underlying neuropathic condition that causes the pain. When competently performed, IMS has a remarkable success rate, as proven by the amelioration of symptoms and signs, even for chronic back pain with root signs.
