Muscle function may depend on model selection in forward simulation of normal walking.

摘要: The purpose of this study was to quantify how the predicted muscle function would change in a muscle-driven forward simulation normal walking when changing number degrees freedom model. Muscle described by individual contributions vertical acceleration center mass (COM). We built two-dimensional (2D) sagittal plane model and three-dimensional (3D) OpenSim used both models reproduce same data. Perturbation analysis applied deduce each excitations COM support were compared between 2D 3D models. found that able similar joint kinematics kinetics patterns as Individual different for most hip muscles but ankle knee attain excitations. Total induced gravity However, varied, especially muscles. Although there is currently no standard way validate predictions, seems be more appropriate estimating function.
