This study is to develop the Functional Electrical Stimulation (FES) cycling system for hybrid exercise of in-home use. Several new features, including friendly man-machine graphic user interface (GUI), portable stimulator and better mechanical design for convenient operation at home, were implemented in this FES-cycling device. The hybrid exercise ergometer was performed with arm-cranking and leg-cycling. Arm-crank can be used to initialize cycling by the individual and warm up before electrical stimulation. The user can slide into the U-shape track of ergometer and perform the FES-cycling exercise directly on the wheelchair. Additionally, voluntary upper body exercise by using arm-crank can improve much in cardiopulmonary function. The new stimulator and controller reduce much space and make it portable for in-home use. The controller was based on pocket PC (PPC) for control and data acquisition. A control scheme with two fuzzy logical controllers (FLC) was also adopted to control the stimulation pattern and stimulation intensity of two legs separately. With the wireless transmission capability, the recorded cycling data were transmitted to clinical center for cycling smoothness evaluation as well as for redesign of training protocol.
New control scheme with two FLC is adapted for the paraplegic subjects with asymmetrical muscle force. This new control scheme allows to individually adjust the stimulation intensity depending on the muscle force of each leg, therefore cycling time before muscle fatigue can be prolonged. The new hybrid exercise ergometer not only reduces the space but also is convenient to operate at home. For further development, we expect that this novel FES-cycling device with two FLC can assist the hemiparetic stroke in the progress of rehabilitation toward better ambulation process.
