Outline of Final Research Achievements |
Functional Electrical Stimulation (FES) is considered effective to recover the motor function of the paralytic by inducing muscle contraction with paralytic electrical stimulation. However, the strong fatigue and avoidance response when using FES is yet to be overcome in order to improve its effectiveness and acceptability. This study therefore developed a muscle fatigue evaluation method according to the frequency characteristics of the electromyography associated with FES, and elucidated the relationship between FES parameters and the induced body movement and cortical activation. The FES device developed based on the findings of this study was validated by subjects with leg paralysis. The expansion and shrinkage of the brain areas activated was observed during the long-term exercise using the FES device.
