Muscle Energy Technique in Patients With Nonspecific Low Back Pain

Post isometric relaxation involves the peripheral and central modulating mechanism by activating the muscles and joint mechanoreceptors. It can be effective for a variety of purposes including lengthening a shortened muscles, as a lymphatic or venous pump to aid the drainage of fluid or blood and increasing the range of motion. MET is a manual therapy intervention that can be used to stretch or lengthen muscles and fascia that lack flexibility.

The 90/90 exercises for abdominal and hamstring activation rotate the pelvis posteriorly in the sagittal and transverse plane, into a more neutral position. Hamstrings extend the hip, and therefore reciprocally inhibit hip flexors. Hamstrings and abdominals also aid in inhibiting paraspinal muscles via a posterior pelvic tilt / hip extension, a decrease in lumbar extension, and an increase in lumbar flexion.
