Patent ID: 7587937

Claim:
A system for providing biofeedback information to a subject for gait assistive therapy, comprising: an insole pressure sensor, comprising: a lower layer of foam having an upper side; a plurality of bottom conductive elements mounted to the upper side of the lower layer of foam; a middle layer of foam defining at least one plurality of holes, the at least one plurality of holes comprising a first plurality of holes that are positioned proximate a heel portion of the middle layer of foam and a second plurality of holes that are positioned proximate a ball portion of the middle layer of foam; a plurality of conductive foam cores, wherein one foam core is positioned into each hole of the at least one plurality of holes; an upper layer of foam having a lower side; and a plurality of bottom conductive elements mounted to the lower side of the upper layer of foam, wherein the lower layer of foam is mounted to a bottom surface of the middle layer of foam and the upper layer of foam is mounted to a top surface of the middle layer of foam to form a flexible shoe insert; and a means for communicating audio feedback to the subject indicative of pressure applied by the ball and heel portions of the subject's foot to the insole pressure sensor.
