| Outline of Final Research Achievements |
We observed that double transcranial magnetic stimulation with maximum voluntary muscle contraction (TMS with MVC) tended to increase amplitudes of motor evoked potentials (MEPs) compared with single TMS with MVC in healthy adults. Based on this result, we carried out a placebo controlled crossover trial to aim to verify the efficacy of double TMS with MVC in patients with chronic hand paresis caused by stroke. As a result, the real stimulation significantly increased maximum pinching force from the first day of stimulation. MEP amplitudes or areas, and scores of pegboard test did not significantly differ between the conditions. Therefore, we think that double TMS with MVC is useful to increase muscle power in patients with chronic hand paresis caused by stroke.

| Academic Significance and Societal Importance of the Research Achievements |
今回の研究において、最大筋収縮磁気刺激が正常者や脳卒中による慢性的上肢運動麻痺患者の運動機能訓練法として有用であることが示された。また磁気刺激の方法としては単発刺激よりも二連発刺激の有用性が示唆された。この結果に基づき、高齢者の筋力低下や神経疾患による運動麻痺の機能訓練法として、二連発刺激による最大筋収縮時磁気刺激を応用することが可能となり、高齢化社会における要介護者の予防の観点から、研究的意義は極めて高いと思われる。
