| Outline of Final Research Achievements |
In this study, we used three-dimensional geometries of the foot surface, bone, and Achilles tendon extracted from medical imaging to construct a finite element model accounting for the internal structure of the foot. Additionally, we used a motion capture system to measure the movement of the foot during ground contact while running and landing, and computed each variable used to validate the finite element model.
We will further pursue studies on the construction of the finite element model and confirm the validity of the model. Thereafter, a simulation with ground contact by altering the material properties and other factors will be conducted to identify the effects on bone behavior and the resultant mechanical phenomena.
