ABSTRACT:
A method and apparatus for exercising the subtalar complex with controlled triplaner motion. The principal embodiment includes a standing platform and handrail in association with a rotatable foot plate. The foot plate is controllable and adjustable in three planes with fixed settings in all planes, including the oblique. The exerciser provides a method for isolating specific muscle groups involved with foot, ankle and calf extensions or where combinations of muscles are used, such as, with dorsiflexion-eversion or plantarflexion-inversion, while preventing tibial rotation of the foot. A second embodiment provides a more portable exercise apparatus utilizing the concepts employed with the principal embodiment wherein a rocker member is provided, attached to a support member. A foot plate attaches to the support member opposite the rocker and is pivotal in the transverse and frontal planes.
