<p>The Therapeutic gymnastic apparatus comprising a foot pedal the upper part (7) of which is coupled over a hinge (b) to an adjustable drive rod (13) and can thus be moved up and down exerting feed and toes. The force transmitted over the trust rod (13) and pedals (11) has a massaging effect on the leg muscles and joints. The force can be adjusted by altering screw coupling (3) Pedal brakes (12) come into action as the lost pressure as the feed leave the pedals, rather than during pedalling. The apparatus can be used in an ordinary chair rather than an uncomfortable saddle and the pedal action copiers the rolling motion of a ship rather than turning horizontally about its axis.</p> |
