Abstract: The present invention relates to an ordinary crutch modified with a straight support which may be formed from a solid, lightweight tubular member, said support connected at one end to near the bottom portion of the crutch and with a bicycle pedal-like cushion on the other end for which the calf, shin or cast of the injured leg or leg of the injured foot rests. Since the pedal can freely revolve from its attachment to the solid support member, the angle at which the leg rests on the pedal relative to the crutch may be readily optimized for the patient's comfort in order to relieve pain and discomfort. Also, fatigue from the body when supporting the dangling leg may be avoided as the leg no longer dangles with its concomitant “dead weight”, because the entire weight of the leg is resting on the cushion of the leg support, the knee is flexed or extended while standing, or while sifting.
