Outline of Final Research Achievements

We investigated whether increasing or decreasing the amount of exercise load affects muscle strength, walking function, and cognitive function in stroke patients. Increasing the amount of exercise load improves muscle strength and lung capacity, but once a certain load is exceeded, the improvement effect does not increase and plateaus. The load at which walking function plateaus was greater than that for muscle strength or lung capacity. Meanwhile, cognitive function showed unidirectional improvement as the amount of exercise load increased. It was thought that walking function was largely influenced by the increase in muscle strength and lung capacity associated with activity behavior correlation, as well as the acquisition of skills through motor learning.

Academic Significance and Societal Importance of the Research Achievements

脳血管障害後のリハビリテーション治療において、ある程度の運動負荷は必須であるが、筋力はプラトーに達しても、運動学習を行うことで歩行機能は改善する可能性がある。慢性期脳血管障害患者においてもリハビリテーションの継続は歩行再建を目指せる可能性がある。
