ABSTRACT:
This isometric/isotonic exercise and physical therapy system is based on a series of elongated exercise rods made of urethane or other resilient, elastomeric resin that is both bendable and twistable. The exercise or therapy afforded by the system depends on the resilient exercise rod or rods; for a relatively limp, low-resistance rod the exercise is essentially isotonic, but with stiffer rods isometric exercise or therapy is provided. The system includes devices that mount the rod or rods on the person using the system for varied exercises of the knee, elbow, hip, wrist, back, or virtually any other portion of the user's anatomy.
