Abstract:
A robotic module which can be attached to an exercise apparatus provides enhanced physical therapy for victims of stroke or other maladies or accidents by simulating normal or arbitrarily modified profiles of angular position of an extremity such as a foot in accordance with a position of that extremity along a locus of repetitive motion. A closed-loop control system which is included in the module provides regulation which reduces or avoids spastic responses often found in poststroke patients during gait rehabilitation.
