diagnostic assessment designed to measure the presence of a flexion contracture of the hip. The patient is placed supine and the uninvolved hip and knee are placed in maximum flexion (in a knee-to-chest position). When a flexion contracture of the opposite hip is present, the thigh will spontaneously elevate, thus indicating the amount of contracture present.

A test used to identify hip flexor contractures. Lying supine with the legs off the end of the table, the patient flexes the knee and tries to pull the thigh to the chest. Inability to perform this maneuver or extension of the opposite knee indicates tightness of the iliopsoas or rectus femoris muscle.
