Outline of Final Research Achievements

First, it was possible to identify the presence of a mechanical energy flow from the dorsal lumbar muscles to the paralysed side of the lower limb in the standing up movement of stroke patients. This is considered to be a movement strategy to protect the motor paralysis. In addition, during postural maintenance in acute stroke patients, some patients modulated muscle activity in response to stimulation when electrical stimulation was applied to the lumbar dorsal muscles. On the other hand, there was no significant change in posture itself and the effect was limited. The number of cases was small and additional measurements are still needed.

Academic Significance and Societal Importance of the Research Achievements

脳卒中患者の立ち上がり動作における運動麻痺の代償関係を明らかにできたことは、今後のリハビリテーションの発展や装具開発に貢献できる。また、急性期の姿勢保持における電気刺激の効果を明らかにしたことで、急性期から提供できるリハビリテーション領域を拡大できた。前者の結果は論文化されており、一般化と言う点でも貢献度が高かったと考えられる。一方で、後者の結果は小数例に留まっており、追加計測・解析を行うことで社会実装において更に大きなインパクトを与えうる。
