| Outline of Final Research Achievements |
We obtained certain findings on the relationship between gaze and the excitability of anterior horn cells of the spinal cord in the observation of locomotion in healthy subjects. When the subject gazed at the movement site and observed the movement performed by others (video images), the excitability of the anterior horn cells of the spinal cord corresponding to the muscles involved in the movement increased. For application to rehabilitation, we believe that when muscle output is reduced for some reason, such as disease or disuse syndrome, the anterior horn cells of the spinal cord are excited by having the subjects gaze at and observe the motor area of the movement involving the muscles concerned, leading to an increase in muscle output. In the future, we would like to demonstrate the effectiveness of motion observation through clinical application.

健常者を対象とした、運動観察における視線と脊髄前角細胞の興奮性との関係性として、一定の知見が得られたと考える。これまでの研究結果を総合的に判断し、他者が行う運動（映像）に対して、運動部位に集中し視線を向けながら観察すると、運動に関与する筋に対応した脊髄前角細胞の興奮性は増大することが判明した。この知見をリハビリテーションへ応用するには、疾患や廃用症候群等による何らかの原因で筋出力の低下が生じている場合には、治療として運動観察は選択肢の一つとなり、当該筋が関与する運動を運動部位に視線を向けながら観察させることで、脊髄前角細胞は興奮し、筋出力の増大に繋がるのではないかと考えている。
