Isotonic-isometric device for exercise and physical therapy

Abstract

This isometric/isotonic exercise and physical therapy device employs an elongated exercise rod preferably made of urethane or other resilient, elastomer resin. The exercise rod is releasably mounted, as by a set screw, in a socket that in turn is mounted on a metal base. The exercise rod may have one end secured in the socket; in other embodiments the socket is tubular and the elastomer rod extends through the tube. Different forms of mounting apparatus mount the base of the device on a stable support such as a floor, a desk, a table, a cabinet, a wall, a door, or a door frame. The base mounts include a vacuum cup for surface mounting, a clamp for a table or desk edge mount, and a floor-to-lintel doorway mount. The exercise/therapy use of the device depends on the resilient elastomer exercise rod; for a limp, low-resistance rod the exercise is essentially isotonic, but with stiffer rods isometric exercise is provided.
