Outline of Final Research Achievements

Evaluation of dynamic alignment is important to determine the fit of a lower leg prosthesis, but there is no objective indicator, and the skill of the physician or prosthetist who determines fit has been a problem. In this study, we developed software that focuses on dynamic alignment.
We believe that this software will improve gait by providing objective data to users. It can also be used to improve the skills of physicians, physical therapists, and prosthetists. In addition, even in situations where it is not possible to see the patient directly, it will be possible to adapt a prosthetic leg with a desirable alignment for the user, which will be useful from an administrative standpoint.

Academic Significance and Societal Importance of the Research Achievements

本ソフトウェアを使用することで、利用者に客観的なデータを提示することが可能であり歩容の改善につながると考える。また、医師や理学療法士、義肢装具士のスキルアップに使用することも可能である。また、直接本人を見ることができない状況下でも、利用者にとって望ましいアライメントの義足を適合することが可能となり、行政が適合の判定を下す上でも利用することができる点で有用と考える。
