Muscle Energy Technique and Muscle Flexibility

The contralateral leg may be either flexed or may lie straight on the plinth. The affected leg will be flexed at both the hip and knee joints, and then slowly straightened by the therapist until the restriction barrier is identified. The limb will be moved a little away from the restriction barrier and the isometric contraction against resistance is introduced. The patients will be asked to resist the movement with no more than 25% of strength. The contraction will be held for 7-10 seconds followed by complete relaxation of the limb. On exhalation, the knee joint will be straightened (extended) towards its new barrier, and through that barrier a stretch will be applied and maintained for 30 seconds. 3 repetitions

The supine patient will ask to fully flex the hip and knee on the affected side. The affected leg will then be slowly straightened by the therapist until the restriction barrier is identified. The calf of the affected leg will then be placed on the practitioner's shoulder that stands facing the head of the table on the side of the affected leg. Then the patient will be asked to attempt to straighten the lower leg utilizing the antagonists to hamstrings, employing approximately 20 percent of the strength of the quadriceps. This will be resisted by the practitioner for 5 to 7 seconds. Appropriate breathing instructions will be given. On exhalation, the knee joint will be straightened (extended) towards its new barrier and through that barrier a stretch will be applied and maintained for 30 seconds. 3 repetitions)four repetition
