In this study, we designed and fabricated a prototype of an electrically assisted wheelchair pedaled by the electrically stimulated lower limbs. This design not only allowed the paralyzed lower limbs to achieve periodic cycling exercises but also made the rehabilitation process more versatile and interesting. A six-bar lower limb cycling model was developed combining a muscle model to lay a foundation for a theoretical study. The system was equipped with a disk motor incorporated into the front wheel which would provide power assistance when the wheelchair is in a up-hill situation, or the muscle fatigue sign is on, or the patient simply gets tired. In this study, seat position adjustments was designed for ergonomic reasons.application/pdf140070 bytesapplication/pdfzh-TW國立臺灣大學醫學工程學研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22324/1/882614E002001.pdf
