Outline of Final Research Achievements

In this research project, we investigated the use of human motor models obtained by electrical stimulation and obtained the following results: 1) We proposed a new rehabilitation method using motor models as a control model for EMG-driven avatars. 2) We investigated human perceptual characteristics using the developed avatar. 3) We showed the possibility of using motor models obtained by electrical stimulation for diseases such as sarcopenia. 4) As an investigation of the perceptual characteristics relate to the motion model, we investigated the method of presenting haptic stimuli and how haptic stimuli affect perception. 5) We proposed a deep muscle stimulation method without using interference wave stimulation. 6) We developed the clenching movement interface in spinal cord injury patients.

Academic Significance and Societal Importance of the Research Achievements

本研究課題により得られた電気刺激を疾患の検査に使用するという知見は,今後運動モデルを新しいPersonal Health Recordsとして運動器ヒューマンデジタルツイン実現に活用するという試みにつながると考える.また,得られた運動モデルをアバターに移植して体験するというメタバースにおける新しいリハビリテーションが提案できる.これらは,今後リハビリテーション(予防医学における三次予防)とヘルスケア(一次・二次予防)のシナジーを創出することにつながると考える.
