ABSTRACT:
An ankle exerciser for strengthening healthy ankles and for rehabilitating injured ankles. The exerciser includes a foot plate attached by a universal swivel joint to a support post. The universal swivel joint allows the foot plate to tilt or pivot about both longitudinal and transverse axes. Shock absorbers, having one end universally mounted to the foot plate, stabilize the foot plate, provide resistance to the pivotal movement, and limit the movement of the foot plate to the four basic directions of movement that are beneficial to strengthening the desired muscle groups. The exerciser makes it possible to successfully isolate the muscles involved in dorsiflexion, plantarflexion, inversion, and eversion while preventing tibial rotation of the foot.
