Outline of Final Research Achievements

The brain activity during motion exercise varied depending on the handedness. There was an individual difference in the movement of the non-dominant hand and the difference became particularly remarkable in complexity movement. However, there was no clear difference in the brain activity between dominant and non-dominant hand during the sensory input exercise. It was necessary to consider handedness during motion exercise, but not to consider it during the sensory input exercise.
tDCS improved the ability of motion exercise and motion imagery, and it was suggested that it might also improve the ability for sense. As for the mirror therapy, its effectiveness for the motion exercise was supported by the measurement of brain activation, however, it was not able to confirm its efficacy for the sensory input exercise.
