Multiscale Modeling and Time-Scale Analysis of a Human Limb

A multi-scale modeling approach is proposed in this paper that assists the user in constructing musculoskeletal system models from sub-models describing various mechanisms on different levels on the length scale. In addition, dynamic time-scale analysis has been performed on the developed multi-scale models of various parts of a human limb: on wrist, elbow and shoulder characterized by different maximal muscle and skeletal length properties. The time-scale analysis results have been represented on a scale-map, that can be used effectively to direct the simplification of multi-scale models for control-related application purposes.
