To reduce muscle tension, increase flexibility, and lengthen tight muscles (like the piriformis in Piriformis Syndrome).\n\nPosition the patient in a stretch position for the tight muscle just before the point of resistance. Then ask the patient to perform a gentle isometric contraction of the tight muscle (e.g., piriformis) for about 5-10 seconds against minimal resistance. After contraction, the patient relaxes for a few seconds. During this relaxation, the therapist passively stretches the muscle to a new barrier and holds for 15-30 seconds. Repeat 3-5 times. So, the whole treatment session will be of 50 minutes. This technique will be applied twice a week for 4 weeks.",[9],null,{"type":6,"name":15,"description":26,"armGroupLabels":27,"otherNames":24},"Reciprocal Inhibition is another MET technique where the antagonist of the tight muscle is contracted, which reflexively causes the tight (agonist) muscle to relax. To inhibit the overactive muscle by activating its opposing muscle group, allowing for greater stretch and flexibility. Place the muscle (e.g., piriformis) into a gentle stretch. Ask the patient to contract the antagonist muscle (e.g., hip adductors\u002Finternal rotators) for about 5-10 seconds. Therapist then passively stretches the target muscle (e.g., piriformis) further.
