Electrode Selection System for Motor Point Based on Current-Joint Angle Characteristics Model
None:
Functional electrical stimulation (FES) is a rehabilitation approach for motor paralysis. In these methods, it is crucial to accurately place stimulation electrodes at the motor points (MPs) of the target muscles. This study outlines a novel electrode selection system based on a current-joint angle characteristic model. The proposed system enables to evaluate quantitatively the effectiveness of stimulation electrodes using a characteristic model of the joint angle response to stimulation current, allowing the selection of appropriate electrode placements. An electrode selection experiment was conducted using a 64-channel electrode array. The results show that the selected electrodes are equivalent to or superior to those identified by anatomical exploration, and indicate the effectiveness of the proposed system for FES control.
