Abstract

In quadriplegic patients, power grasp, lateral pinch and prehension for grasping cards are realized by multichannel functional electrical stimulation (FES) applied chronically to the forearm nerve-muscles. It is known that the relationship between muscle strength and the stimulus intensity shows nonlinear characteristics so that effective proportional control of the paralyzed hand is not easily produced by the previous FES system. For more elegant control, the authors developed a new FES system which generated suitable stimulation waveforms preprogrammed by the built-in nerve-muscle models. The system is based on the high performance micro- computer board (iSBC 86/12A) and some electronic circuitry. The stimulation waveforms compensate for the nonlinearity between muscle strength and the stimulus intensity, and this FES system demonstrated the ability to perfrom smooth movements of power grasp, lateral pinch and prehension for grasping card. The stimulus parameters during electrical stimulation can be modified through the keyboard.
