| Outline of Final Research Achievements |
The aim of this study was to establish a methodology to efficiently assist laryngeal elevation movements by functional electrical stimulation (FES) in order to develop an assistive device to assist swallowing function in daily life. First, we developed a multimodal measurement device of swallowing-related biological signals using PVDF (Poly Vinylidene DiFluoride) film to identify the swallowing intention. In addition, the stimulation position and intensity to induce laryngeal elevation effectively by the swallowing FES were examined, incorporating the musculoskeletal analysis of swallowing.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，これまで試行錯誤的に行われていた嚥下FESの刺激位置・順序・強度を定めるための方法論の確立につながり，日常生活での利用も期待できるようになる．社会の高齢化と共に嚥下機能が低下する人の割合は増えているものの，四肢の運動支援等に比べて嚥下の運動支援に関する研究は極めて少ないため，日常生活の中で嚥下機能を補助するための支援装置の実現に挑む本研究の意義は大きい．
