Muscle energy is a technique that was developed by Fred Mitchell, Sr., D.O. and first described in the book “An Evaluation and Treatment Manual of Osteopathic Muscle Energy Procedures,” published in 1979.
The therapist performing muscle energy determines where there are areas of muscular dysfunction and then passively positions the patient at the restricted motion barrier. While the therapist holds the patient in this position, the patient exerts gentle force away from the restricted barrier, which the therapist then resists. The patient is then told to relax and the therapist gently moves the patient through the restricted barrier. This procedure is repeated several times. This process resets the resting length of shortened muscle fibers, thus improving range of motion.
