本研究设计了一种功能性电刺激诱导骑行控制器。该控制器可用于需要恢复运动对称性的偏瘫患者的康复治疗，它在刺激双腿时以脉宽为控制变量，以消除两曲柄臂产生的力矩不平衡。通过健康受试者和中风患者进行的等速试验证实了这一点。结果表明，控制器能够达到并保持对称的踏板。未来，该控制器将在更多的中风患者身上进行验证。
This study deals with the design of a controller for cycling induced by functional electrical stimulation. The controller will be exploitable in the rehabilitation of hemiparetic patients who need to recover motor symmetry It uses the pulse width as the control variable in the stimulation of the two legs in order to nullify the unbalance between the torques produced at the two crank arms. It was validated by means of isokinetic trials performed both by healthy subjects and stroke patients. The results showed that the controller was able to reach, and then maintain, a symmetrical pedaling. In the future, the controller will be validated on a larger number of stroke patients.
