ABSTRACT:
An orthospinal chair for exercising the spinal column and back muscles by placing tension on the spine through partial inversion. The orthospinal chair allows partial inversion of a person in a supine, bent-knee position at an easily controllable angle. The user of the orthospinal chair is retained in a supine, bent-knee position by a restraining strap secured across the hip area which allows the person to apply tension while in a partially inverted position to relieve back pain and strengthen back muscles.
