Abstract
A lower extremity exercise device for performing strengthening exercises for the calf muscles, as well as for performing static or dynamic stretching of the calf muscles. The device is preferably configured to have a generally wedge-shape positionable upon a flat surface. The wedge defines an upper, inclined platform surface for receiving the foot of a user, and has a rounded base portion having an asymmetric, gradually increasing radius to allow the user's foot to smoothly roll or rotate the device forward when pushed thereagainst. In use, the device allows for natural, relative rotations between the forefoot pivot-point and the ankle joint in the sagittal plane.
Claims6
A lower extremity exercise device operative to strengthen and stretch the calf muscles of an individual comprising:
- a. a platform surface sized and adapted to receive the foot of an individual;
- b. at least one side wall member formed beneath said upper platform surface and defining a wedge-shaped profile having a rounded base portion;
- and
- c. wherein said device is operative to position said platform surface in an upwardly inclined position relative level ground in a first resting position and to rotate about said rounded base portion in a second active configuration such that said platform surface correspondingly performs see-saw movements, said transition from said first position and second active configuration corresponding with plantar flexion of said individual's foot positioned upon said upper platform surface.
