| Outline of Final Research Achievements |
The present study showed the combined patterned electrical stimulation with voluntary contraction (PES+VC) can increase the reciprocal inhibition (RI) with 5 min, while it took 20 minutes to induce a significant increase of RI with PES alone and VC alone. In addition, we found that the after-effects of PES+VC on the RI persisted longer compared with PES alone and VC alone after 20 min intervention. These effects were observed in patients with chronic stroke. It has been reported that reduction in the RI is related to abnormal muscle coactivation during locomotion in patients with stroke. Our result provides further support for the idea that the application of PES to the affected leg during locomotion might be a useful adjuvant strategy for functional recovery of locomotion in patients with stroke.
