Abstract
A force sensing insole is disclosed which is adapted to be used in association with an electro-goniometer for analyzing the gait of a patient. The insole includes a body member composed of three overlying sheets of thin plastic material which are bonded together, with the intermediate sheet having cut-outs in each of the heel, ball and toe portions so as to define three separate internal chambers. A contact switch is positioned in each of the open chambers, and which comprises a plurality of parallel fingers formed of conductive ink on the inwardly facing surface of one of the outer sheets, and an area of conductive material on the inwardly facing surface of the outer sheet. The body member includes a laterally extending flexible strip, and which is adapted to flex and extend outwardly from the wearer's shoe. Also, lines of conductive ink are provided in the body member which extend from each of the contact switches to a terminal positioned at the end of the strip.
