| Outline of Final Research Achievements |
Stroke hemiplegia is characterized by impaired heel-to-toe rocker during the late stance phase of gait, increasing the risk of falls. This issue is particularly prevalent among underserved populations in rural areas with limited access to healthcare resources and rehabilitation services. To address this challenge, we aimed to develop a maintenance-free carbon fiber short leg brace that facilitates easy adjustment, fall prevention, and gait assistance.
The brace design incorporated a linkage mechanism at the bottom of the shoe sole to assist in heel elevation. Three-dimensional motion analysis was employed to elucidate the mechanism of heel elevation.
The developed brace successfully facilitated heel elevation during the late stance phase of gait. The mechanism of heel elevation was elucidated through three-dimensional motion analysis. The brace demonstrated effectiveness in gait assistance and heel elevation, but further refinements were required to enhance its durability.

| Academic Significance and Societal Importance of the Research Achievements |
転倒は遊脚相でつま先を引っ掛けて前方に転倒してしまう割合が多い．その原因の１つにフォアフット機能（単脚支持期に踵を挙げる機能）が破綻していることである．本研究によって単脚支持期に踵を挙げる機序を明らかにすることができたことは，今後の脳卒中リハビリテーションに大きな変革をもたらすことが出来たと考える．
