The Applications Of Alternative Controls For Powered Upper Extremity Prosthetics

Abstract

Currently, non-myoelectric controls for electro-mechanical prosthetic components include pull switches, rocker switches, harness pull switches, push-button switches, touch pad actuators (Universal Artificial Limb), touch switches (Steeper), and momentary contact switches. Often these control systems prove to be invaluable Yet, at the same time, their incorporation into a prosthesis often results in a cosmetically unappealing prosthesis. Furthermore, in certain situations the client may be restricted in range of motion due to soft tissue damage, extensive scarring, or other related problems which limit effective performance of conventional controls Recent experience shows that the application of Force Sensing Resistor's (FSRs) and Capacitive Touch Controls (CTCs) in prosthetics presently have specffic use. An increased awareness of possible applications of FSR and CTC technology is anticipated to spark new and innovative applications in the fields of prosthetics and orthotics.
