| Outline of Final Research Achievements |
This study aimed to realize a home rehabilitation system focusing on motor dysfunction in the lower limbs. First, methods of calculating evaluation indexes of lower limb motor function from inertial sensor signals were developed. Then, an electrical stimulation teaching method to induce active movements for rehabilitation was constructed and its effectiveness was examined in foot drop correction during walking. The stimulation timing of the teaching in pedaling wheelchair rehabilitation was also determined. In addition, in order to assist movements in rehabilitation, methods of assisting foot movements during walking and propulsion of the pedaling wheelchair were developed by using functional electrical stimulation (FES). Finally, a portable system applied to home rehabilitation was developed. Motion measurement and evaluation methods using a few inertial sensors were also proposed for home rehabilitation and shown to be useful in experimental tests.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，運動リハビリテーションにおいて，運動の計測・評価から，運動補助，運動指導の教示まで行えるシステムの実現を目指しており，慣性センサによる3次元運動の計測と評価指標の算出法を構築する点，FESによる動作補助と運動指導の教示をシームレスに提供する技術を開発する点に学術的な意義がある．本研究の成果を実用に向けて発展させることで，理学療法士らの的確な指導のもとにリハビリテーションの効果の向上や期間短縮が可能になると期待され，ニューロリハビリテーション技術の体系化へ貢献し，将来的には，入院の短期化，新しい在宅リハビリテーション法の提供，そして医療費削減につながるという点に社会的意義がある．
