| Research Abstract |
The purpose of this research was to investigate changes of input-out properties on human spinal circuits after passive ground stepping (PGS) and electrical nerve stimulation (ENS). PGS on the treadmill was assisted by a robotic driven-gait orthosis. ENS was applied to the common peroneal nerve (CPN) in the right leg. The following three interventions were randomly applied for 30 minutes: PGS alone, ENS alone and the combination of these two types of interventions (PGS+ENS). Before and after these interventions, the soleus H-reflex and disynaptic reciprocal inhibition from the common peroneal nerve to the soleus motoneuron were assessed. The results showed that the amounts of reciprocal inhibition were changed after PGS+ENS. Thus, it was shown that short-term plasticity on spinal circuits can be induced by the combination of afferent inputs from multiple pathways.
