| Outline of Final Research Achievements |
The human foot has been thought to possess the mechanical function modulating the mobility of midtarsal joint at the late stance phase for generation of the effective propulsive force. However, due to the complex foot anatomical structure, the details of so-called midtarsal joint locking mechanism have not been fully investigated. In order to clarify the detailed mechanism of the human foot function, cadaver experiment using a biplanar X-ray fluoroscopy system and numerical simulation based on a finite element model of the human foot have been conducted.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の試みによって、これまで困難とされてきた足部の骨格動態や、それによって生じる生体内力の推定が可能となり、ヒト足部が持つロック機構のメカニズムの一端が明らかとなった。また本研究で提案された方法論は、ヒト足部の歩行機能の理解だけでなく、頑強な二足歩行を生成する足部機構の提案といったロボット工学分野や、足部疾患の発症メカニズムの解明といった医療分野、さらには直立二足歩行の進化過程の解明といった生物人類学分野まで、幅広くインパクトを与えることが期待される。
