Intramuscular Stimulation (IMS) is a type of manual therapy that involves the insertion of thin, solid needles into the muscle tissue to release tension and relieve pain. It is a form of acupuncture, but it focuses more specifically on the muscles rather than the traditional Chinese acupuncture points. IMS is based on the theory that chronic pain is often caused by muscle shortening, which puts pressure on nerves and causes pain signals to be sent to the brain. By inserting needles into the shortened muscle fibers, IMS can stimulate a healing response and help to release the tension in the muscle tissue, thereby reducing pain and restoring normal movement. IMS is typically performed by a trained practitioner, such as a physiotherapist or chiropractor, who will assess the patient's muscle tension and pain levels before inserting the needles. The needles are usually left in place for a few minutes, and the treatment may be repeated several times over the course of several weeks to achieve optimal results.
