The AnyBody™ Modelling System (AMS) is an universally used musculoskeletal simulation software using inverse dynamics. Until now, no complete human hand model is realized in the AMS. Considering other musculoskeletal hand models [1], no validation based on dynamic movements has been investigated yet. The aim of this work is to implement a full detailed hand model for the AMS including all extrinsic and intrinsic muscles using data from an anatomic study. For validation purposes, the calculated muscle activities are compared to electromyographic (EMG) data.
