Patent ID: 8249714

Claim:
A device for performing a plurality of successive cycles of a closed-chain exercise with partial bodyweight loading for the lower extremities of a human subject including the legs, using stimulation, comprising: a frame; a sled for receiving the subject facing generally upwardly and mounted to the frame for translating from a first, lower position with the legs at least partially bent to a second, higher position with the legs less bent than in the first position; a pedal support for supporting at least one of the subject's feet, wherein the pedal support comprises a receiver mounted for moving as the sled moves from the first position to the second position, and a sensor for determining a relative position of the receiver during the exercise; an electrical stimulator for applying electrical stimulation to the human subject; and a controller for generating a plurality of output signals to control the stimulator during each exercise cycle to provide the electrical stimulation in an amount sufficient to cause the subject to move the sled from the first position toward the second position, whereby the stimulation provided may be automatically adapted by the controller for each successive cycle of the exercise.
