| Outline of Final Research Achievements |
The purpose of the present study is to determine whether the effects of ENS (electrical nerve stimulation) during passive stepping are dependent on the timing of the stimulation during the stepping cycle. Passive stepping on the treadmill was assisted by a robotic driven-gait orthosis for 30 min. Peripheral nerve stimulation was applied to the right common peroneal nerve (CPN) during the swing phase (ENSswing) and stance phase (ENSstance) of the step cycle in the right leg. During each intervention, spinal reciprocal inhibition (RI) to the soleus muscle was assessed before (i.e., baseline) and after the interventions. The result showed a phase-dependent effect of ENS of the CPN on the short-term plasticity of spinal RI during passive stepping. Compared to the baseline, the amount of RI was increased after the ENSswing intervention, whereas it was decreased after the ENSstance intervention.
