Abstract: A prototype of wireless surface electrical stimulation system combined with the fuzzy FES controller was developed for rehabilitation training with functional electrical stimulation (FES). The developed FES system has three features for rehabilitation training: small-sized electrical stimulator for surface FES, wireless connection between controller and stimulators, and between controller and sensors, and the fuzzy FES controller based on the cycle-to-cycle control for repetitive training. The developed stimul… Show more

“…Two wireless electrical stimulators were used in experiments, which were developed based on our previous study [24]. The stimulation data are transmitted to the stimulator via a 2.4GHz wireless transceiver module (MK72660-01, LAPIS Semiconductor Co., Ltd.) from the portable computer.…”

“…Stimulation data were transmitted to the surface electrical stimulator through the 2.4 GHz wireless transceiver modules from the PC. The wireless surface stimulator operated in 2 AAA batteries, which was developed in our laboratory based on [8], generates electrical stimulation pulses immediately after receiving the stimulation data. Stimulation timing was determined by the acceleration (longitudinal axis) and the angular velocity signals measured with the inertial sensor attached on the shank of the hemiplegic side.…”

“…However, stimulation intensity was fixed for each cycling period. That is, continuous time closed-loop control is re- [6], [7] that was for a kind of repetitive control. Then, the controller was examined in controlling knee extension movements by comparing to a PID controller with healthy subjects in order to evaluate control performance.…”

“…Output of the fuzzy controller is adjusted by error-based output adjustment factor (E-OAF). The E-OAF is determined by the angle error, which increases the output value of the controller if the error is large [7].…”
