The majority of us have hip flexion contractures, i.e., an ilio-psoas muscle which has become shortened due to the amount of time we sit. The gymnasts we see who have maintained the flexibility to touch their gluteus maximus with the back of their head do not, needless to say, have hip flexion contractures. The manner in which one verifies a hip flexion contracture is by using the Thomas position as taught by the American Academy of Orthopedic Surgeons. Because the ilio-psoas muscle is tight it becomes like a stretched rubber band when we lay supine and because the weight of the leg is greater than that of the abdomen, the Lumbar spine is pulled into excessive lordosis and the result is discomfort. Notice that the first thing people do when they roll to their side is bend their hips and knees. This is the same position as when they are using "The Angle". Placing "The Angle" under the knees flexes the hip which brings the insertion end of the ilio-psoas muscle (one end of the rubber band) closer to its origin in the lumbo-sacral region of the spine. This results in less tension on the muscle and the lumbar spine can return to it's neutral comfortable position.
