| Outline of Research at the Start |
本研究の目的は，筋電電動義手（以下，筋電義手）使用者の筋電ハンド制御時の断端部筋電信号および視線軌跡等の生理学的特性と筋電義手操作時動作の運動学的特性を分析して筋電義手操作訓練の効果と課題を明らかにすることである．本研究は，片側前腕切断者と先天性上肢欠損児（前腕部）と健常人を対象に実験を行い，筋電ハンド制御時の断端部筋電信号および認知機能の特性と筋電義手操作能力に関する基礎的データの集積を行う.これにより筋電義手操作能力の評価と訓練方法の基準が明確となり,上肢切断者および先天性上肢欠損児の身体的かつ精神的負担の軽減に繋がり，リハビリテーション実施期間の短縮が期待できる．

| Outline of Final Research Achievements |
The purpose of this study was to analyze the physiological and kinematic characteristics of myoelectric and active prosthetic hands and to clarify the effects and challenges of operation training.
One-hand and two-hand manipulation tasks were performed, and each training was carried out for two weeks. The results indicated that there was no difference between one- and two-handed manipulation training in the ability to open and close the myoelectric prosthetic hand, and that two-handed manipulation training was more effective than one-handed manipulation training in the ability to manipulate objects, especially in accurately manipulating an object grasped with the tip of the myoelectric prosthetic hand. With regard to visual cognitive abilities, the results suggest that the two-handed manipulation task requires greater visual attention to open/close control of the myoelectric hand and manipulation of the object compared to the one-handed manipulation task.
