The non-linear response of a muscle in transverse compression: assessment of geometry influence using a finite element model.

abstract：:The aim of this study was to develop a generic musculoskeletal model of a healthy 10-year-old child and examine the effects of geometric scaling on the calculated values of lower-limb muscle forces during gait. Subject-specific musculoskeletal models of five healthy children were developed from in vivo MRI data, and t...
