Abstract [en]

This paper discusses the simulation of forces in a musculoskeletal system. The main focus is on the treatment of static and dynamic equilibria for a redundant force system, where the distribution of the required force for maintaining a posture or performing a movement is not unique. Reference is made to some general aspects of redundancy, and a brief discussion of the static optimisation method follows. This leads to a general framework for static optimisation, where different performance criteria can be introduced. Also dynamic equilibrium during movement is discussed, and a temporal finite element viewpoint is introduced for the treatment of target-controlled movements. This also leads to a rather general framework, where different criteria for optimal movement can be introduced. From both static and dynamic optimisation algorithms it can be concluded that existing numerical descriptions of muscular behaviour are missing some important elements, primarily related to memory aspects of the function. Finally we discuss some ideas around the types of research required in the area of muscular force production.
