Abstract:
1. Apparatus comprising in combination a mechanism for moving an extremity of a limb along a substantially elliptical locus, a sensor for determining locations of a portion of said mechanism along said substantially elliptical locus, an actuator responsive to said sensor for guiding an angular position of said extremity that simulates a repetitive motion of said limb corresponding to respective positions of said extremity along said substantially elliptical locus whereby said angular position of said extremity and said position of said extremity along said elliptical locus are decoupled and said angular position freely established for each position on said substantially elliptical locus, and a closed-loop control system which regulates an attenuation level of responsiveness of said actuator to said sensor in accordance with a change of force of said extremity against said portion of said mechanism.
