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.
Claims19
Apparatus comprising in combination
- a mechanism for moving and 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, and
- an actuator responsive to said sensor for guiding an angular position of said extremity that simulates a repetitive motion of said extremity of said limb corresponding to respective positions 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.
A robotic module for attachment to an exercise apparatus, said module comprising
- a sensor for determining locations of a extremity of a person along a substantially elliptical locus of repetitive motion of a limb, and
- an actuator responsive to said sensor for guiding an angular position of said extremity that simulates a repetitive motion of said extremity 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.
