Musculoskeletal models of a human and bonobo finger: parameter identification and comparison to in vitro experiments

Abstract

This study presents the first attempt to implement both a human and non-human primate finger model for comparative palaeoanthropological studies. The good agreement between predicted and experimental forces involving the action of extrinsic flexors-which are most relevant for forceful grasping-shows that the models are likely sufficiently accurate for comparisons of internal loads occurring during human and non-human primate manual activities.
