Abstract: A device for prevention of ulcers in the feet of diabetes patients is embodied in a footwear article such as in a shoe. The device includes a sensor disposed in a contained liquid mass of a hydrocell carried in the shoe inner sole, the sensor being one that detects both pressure and temperature values to which the patient's feet are exposed. The sensor includes a bridge circuit comprised of four piezoresistors arranged in two diagonally arrayed pairs, the resistance of one pair of resistors increasing and the resistance of the second pair decreasing in the presence of an increase in the pressure condition in the hydrocell, the resistance of all the resistors increasing or decreasing responsive to respective increases and decreases of temperature in the hydrocell.

Abstract: The ankle joint orthesis for the stabilization of the internal and external ankle joint comprises a medial shell and a lateral shell made of plastic. The shells extend from the heel region beyond the malleolus to the lower calf region. The shells are lined throughout the entire support surface with a flexible padding. Loop and hook type fastening structure are provided for fastening and securing the shells. One shell, preferably the lateral shell, is of an L-shaped design and has a laterally extending leg which extends below the foot between the heel and the ball of the foot. Both shells can be connected to each other by loop and hook type fastening structure under the foot, e.g., a selectively adhesive strap fastened to one of the shells and passing under the foot for being adhesively secured to a mating strap closure on the other shell. Both shells have openings in the malleolar area.
