Outline of Final Research Achievements

The purpose of this study is to explore rehabilitation strategy that can facilitate rehabilitation outcome with enhancing patient's motivation level. To this end the transcranial direct current electrical stimulation (tDCS) was utilized to stimulate the brain area related to motivation. The operant conditioning to the spinal stretch reflex (H-reflex) was compared between two subject groups, tDCS and sham groups. The results showed that in tDCS group the H-reflex conditioning effect seemed to be higher than the Sham group. It was suggested that the higher motivation level that was augmented with tDCS can enhance spinal plasticity and as the result increase rehabilitation outcome.
