Overview Function Piriformis is a lateral/external rotator of the hip joint. Innervation Levels: L5, S1-S2 Sciatic nerve often runs through or behind the piriformis muscle Supine Muscle Testing Patient lies supine Grasp above the ankles bilaterally (important to grab above the ankle joint) Using the lower extremity, internally rotate each […]
Used to evaluate hypertonicity of the iliopsoas Begin with the patient supine, the patient takes both legs and passively flexes the knees and hip to flatten the lumbar lordosis. Remember to watch for increased lumbar lordosis (should not have this because it’s compensatory) – monitor this with placing your hand below […]
Used to test for hypertonicity of the quadriceps muscle, specifically the rectus femoris Similar to the Thomas Test, however this test is performed at the edge of the table Patient supine with gluteal crease near the edge of the table Have patient bring both knees to chest then let one leg […]
Used to assess for hypertonicity of the iliotibial band Begin with patient in the lateral decubitus position, passively abducted the leg with the knee flexed to 90 degrees while keeping hip joint in neutral position The leg is then released from abduction, while still supporting the calf/ankle – hold onto the […]
