Muscle Energy is popularly known as “MET” is a form of manual therapy that uses the gentle muscle contractions of the patient to relax and lengthen muscles to help normalize joint motion which can used to assist the rehabilitation your recovery from injury.
It is based on the principle of reciprocal inhibition, a theory that muscles on one side of the joint will relax to accommodate the contraction of muscle on the other side of that joint when indirect pressure is applied.
Originally MET is derived from osteopathic techniques from a study by Dr. Fred Mitchell and his son Dr. Fred Mitch Jr. It uses the patients own muscle energy (the force) while the osteopath presents a stationery surface or anti force. Many athletes will use MET as a preventative measure to guard against joint injury.
