| Outline of Final Research Achievements |
Botulinum neurotoxin (BoNT) injection is effective for reducing spasticity, but the duration of effectiveness is limited for only 3 months, therefore multiple injections are necessary over the long term. Transcranial direct current stimulation (tDCS) is a potentially novel strategy for reducing post-stroke spasticity, and tDCS might prolong the duration of reducing spasticity by BoNT therapy. The purpose of this study was to examine problems with adaptation and feasibility for the BoNT therapy with anodal tDCS for upper limb spasticity of stroke patients as a preliminary study. A single-blind, randomized sham (placebo)-controlled pretest/posttest study was conducted for stroke patients. This study was completed without the need for stopping per medical monitor. No adverse effects were seen during the intervention. Based on the results of this study, BoNT and tDCS appear to be safe, feasible, and well tolerated in stroke patients.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、脳卒中片麻痺上肢痙縮に対するボツリヌス療法（BoNTA）と経頭蓋直流電気刺激の効果増強や効果延長などの併用効果がみられる例も確認されたことから、BoNTA追加施注までの期間を延長することが可能となり、対象患者の身体的負担ならびに医療費の軽減が期待される。また、先進的リハビリの発展の一助につながる。
