| Outline of Final Research Achievements |
We investigated the propulsive effect on walking and walking wheelchair (C - WC) drive by sacral surface electrical stimulation (SES). As a result, the maximum locomotion speed increased significantly in both healthy and walking disabled people. Here, muscle discharge of hamstring muscle and gastrocnemius muscle increased, and in C - WC driving, an increase in torque of hip joint extension and knee joint flexion was recognized, and it was considered to contribute to the promotion effect of SES.
When SES was given to stroke hemiplegics during C - WC driving, the unevenness of the depression acceleration of both lower limbs was immediately equalized. This indicates that contraction process of the paralyzed limb muscles approaches normal. From the above results, it was considered that SES caused neuromodulation effect on the central nervous system networks related to locomotion by its afferent neural activities.
