| Outline of Final Research Achievements |
A gait training rehabilitation robot with functional electrical stimulation was developed mainly for paraplegics with spinal cord injury. It was proven that muscle contraction by functional electrical stimulation decreases the amount of motor torque produced by the robot. We also developed a mechanism that can automatically adjust the amount of robot motor torque appropriate for the subject through machine learning. When paralysis improves, the amount of support torque appropriate for the degree of paralysis is automatically and appropriately provided. After verifying safety in healthy subjects, rehabilitation was performed on paraplegic subjects. No adverse events occurred, and the effectiveness of continued rehabilitation will be verified in the future.

| Academic Significance and Societal Importance of the Research Achievements |
脊髄障害に伴う対麻痺者を主対象とした、機能的電気刺激併用の歩行訓練リハビリテーションロボットを開発した。重度の麻痺がある時から、自身の筋収縮を用いた歩行訓練は機能改善に有効となる可能性がある。機能的電気刺激は神経可塑性に対し有効な治療であり、今後再生医療との併用効果に期待される。
