Abstract: A foot pain relief device can advantageously provide multiple angles of inclination, directed pressure against the plantar fascia, as well as ease of manufacturing and assembly. A toe strap, which is fastened around the ankle and the toe(s), ensures that the toes are flexed up. This toe flexing tenses the plantar fascia of the foot. A ball strap can be threaded through a hole in a ball and then operatively coupled with the toe strap. When operatively coupled to the toe strap, the ball strap keeps the ball positioned on the bottom of the foot while allowing ball mobility. The mobility of the ball can provide directed pressure on at least one component of the plantar fascia. Notably, the simultaneous combination of tension to the plantar fascia and directed pressure to the component(s) of the plantar fascia can be particularly effective at relieving foot pain.

Abstract: Apparatus for use in rehabilitation of a patient with a weight bearing restriction on one or both legs includes a pair of vertically movable horizontally elongated platforms and a pair of corresponding vertically fixed platforms. The movable platforms are connected to a mechanism which applies an upwardly directed preselected force so that as the patient walks with a foot on the movable platform, the movable platform will descend if the patient places a greater weight corresponding to the preselected force. A patient may walk with both feet on movable platforms in which case the weights may be selected for each platform or the patient may walk with one foot on the movable platform and one foot on a fixed platform. The platforms move in a vertical plane arcuately in one embodiment and in a vertical plane linearly in a second embodiment. The weights may be moved relatively to the pivot point and, in addition, the movable platform may be locked in its upward position in this latter embodiment.

Abstract: The invention provides a calf exerciser which safely duplicates the desirable aspects of stair-edge toe lifts. The present exerciser allows a user to transition from a fully contracted position (a "tip-toe" stance) to a fully extended position (much as if one's heels were dropped below the level of the stair on which one rests his or her forefoot to the extent allowed by the exerciser's flexibility). A pivoting forefoot plate pivots with the user's forefoot as he or she transitions between the extended and contracted limits of the toe lift cycles. This eliminates the presentation at any phase of the exercise cycle of a sharp edge (like a stair-edge) to the foot, as well as insures that the user's forefoot (or corresponding shoe portion) remains squarely and safely in contact with a stable surface, despite inherent rocking motion of the feet during each toe lift cycle.

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.

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.

A combination of both types of joint movement are obtained for the actuator in intermediate positions. A wrist CPM device includes a brace for the forearm attached to a semi-circular track on which an actuator is mounted. A hand grip is mounted on a semi-circular bracket and a shaft extends between the actuator and a coupling slidably mounted on the semi-circular bracket.
