lower extremity is taken to a point of tension in the posterior muscles and held there. The patient is asked to push the leg against the shoulder for about six seconds, and then after relaxing, a new motion barrier is found at a greater angle of flexion of the hip. After a few seconds this is repeated, usually three times to achieve a state of enhanced stretch of the muscles and a new barrier to motion at a greater range of joint motion. As with all muscle energy procedures, the resistance need not be more than about 25% of muscle force.
Tips: Most useful in chronic contracture where direct work on the muscle may be too uncomfortable. Least useful in acute muscle strains as it may be too painful. Extra considerations: See the earlier section on principles of muscle energy technique.
30.11 • Muscle energy technique thigh supine The operator is holding the patient's foot against the table and the patient is asked to push against the hand either into flexion of the knee or extension as necessary for the case. The other hand is stabilizing the knee. As in most muscle energy techniques, the force applied by the patient is about 25% of muscle action, and the position is held for about 6 seconds, repeated usually three times with short rest periods between.
Tips: Most useful in small, light subjects where the operator can resist easily. Least useful in large or strong subjects where it may be difficult to keep a true isometric contraction controlled. Extra considerations: See earlier section on muscle energy technique.

Tired Having Back Pains All The Time, But You Choose To Ignore It? Every year millions of people see their lives and favorite activities limited by back pain. They forego activities they once loved because of it and in some cases may not even be able to perform their job as well as they once could due to back pain.
