Outline of Final Research Achievements

Toward establishment of neurorehabilitation for chronic aphasia, we verified whether the effect of tablet-based language training was enhanced by use of transcranial direct current stimulation (tDCS). The participants with chronic aphasia took part in tDCS session and sham stimulation session. In order to investigate the long-term effect and the generalization effect of tDCS use, the performances of naming and sentence production at 2 weeks post-trainings were compared between the two sessions. The results showed greater improvements after trainings with tDCS compared to after trainings with sham stimulation.

Academic Significance and Societal Importance of the Research Achievements

失語症がおかれている社会的背景として,保険制度上,慢性期に受けられるリハビリの回数に制限があることや,身体のリハビリと比べて言語のリハビリを受けられる施設が少ないことなどの問題がある.また,慢性期になるとリハビリの効果が得られにくいといった問題もある.そのような問題に対して、本研究は慢性期失語症のタブレットによる言語訓練及びtDCS併用の有用性を示し,失語症の新しいリハビリテーション環境を創造する基盤となりうる.
