A Dynamic Finite Element Analysis of Human Foot Complex in the Sagittal Plane during Level Walking

摘要: The objective of this study is to develop a computational framework for investigating the dynamic behavior and internal loading conditions human foot complex during locomotion. A subject-specific finite element model in sagittal plane was constructed based on anatomical structures segmented from medical CT scan images. Three-dimensional gait measurements were conducted support validate model. Ankle joint forces moment derived used drive Explicit simulations conducted, covering entire stance phase heel-strike impact toe-off. predicted ground reaction forces, center pressure, bone motions plantar surface pressure showed reasonably good agreement with measurement data over most phase. prediction discrepancies can be explained by assumptions limitations Our analysis that FE simulation improve accuracy peak pressures at some parts 10%–33% compared quasi-static simulation. However, simplify costly explicit simulation, proposed confined only has simplified representation structure. would provide useful tool future extension fully muscle-driven three-dimensional detailed all major structures, order investigate structural dynamics musculoskeletal system normal or even pathological functioning.
