Abstract
This paper describes an improved FES system to restore paralyzed extremities in spinal cord injury patients. For composing stimulus pattern which is suitable for each muscle, electrical stimulus pattern creating system is also developed by using IBM-PC. In the improved portable FES system using V40 microprocessor, muscle fatigue can be decreased by selecting the stimulus frequency which is proper to the response characteristics of each muscle. Driving softwares for the portable FES system and the stimulus pattern creating system are programmed with assembler and C language. A multichnnel portable FES system is designed to minimize the sire and weight using a D/A converter and 32 channel multiplexer.
