Intramuscular Stimulation (IMS) is an effective therapeutic technique used in physiotherapy clinics. IMS uses small, pin-like needles to reduce muscle tension, eliminate pain, restore range of motion, and promote a return to normal function. Sometimes known as Functional Dry Needling (FDN), it is used to treat “trigger points” or “knots” within the body. As the needle is inserted into the muscle tissue, a patient usually experiences a feeling of localized cramping, twitching, or aching within the muscle followed by a release. Despite this initial short-term discomfort, patients respond quickly as it promotes healing and better function.
