Abstract
A device for signaling a patient when a predetermined load is placed on the patient's foot comprises a resilient foot pad having a toe end and a heel end and adapted to substantially cover the inner sole of a shoe. A resilient liquid filled tube is mounted within the pad with the tube extending from adjacent the toe end to adjacent the heel end of the pad. A signaling device is controlled by a pressure responsive means in communication with the liquid in the tube for the actuation of the signaling means at a predetermined pressure of said liquid.
