Outline of Final Research Achievements

The present study investigated whether the combination of Mirror therapy (MT) which have been developed for patients with hemiplegia following stroke and Electrical stimulation (ES) modulated brain blood flow of healthy young subjects and elderly subjects. In young subjects, the brain blood flow of supramarginal gyrus corresponding to the stimulating hand by ES was increased comparing to rest in MT + ES task. On the other hand, in elderly subjects, the brain blood flow of precentral gyrus , postcentral gyrus, supramarginal gyrus, superior temporal gyrus, angular gyrus and middle frontal gyrus corresponding to the stimulating hand by ES was increased comparing to rest in MT + ES task. These results suggested that the combination of the visual input from mirror and synchronized movements by electrical stimulation elicited the effects of motor observation and motor kinesthesia illusion, and more facilitated these effects in elderly subjects with diminished proprioceptive sensation.
