Elliptically based robotic gait trainer (EBRGT)

摘要

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.

主权项

1. 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.
