Muscle forces - bone deformations A novel approach to determine muscle forces corresponding to measured tibia deformations

Abstract

Muscle-force induced strains in bone may be the key to bone-remodelling. But since it proofs to be very difficult to measure these forces directly in vivo, modelling has been the key to answers ever since. The abstract presents a novel approach to create a model that can calculate the forces generated by predefined muscle groups in respect to a given bone deformation. To achieve this, the model will make use of CT-data of the bone, measured bone deformation from an earlier on project and combine these to an inverse dynamics simulation of the lower limb. Thereby, the activated muscle-groups for certain activities can be determined, the occurring strain allotted to these and as a result a strain – activity – force – pattern is created. This data can then be used for further research in the field of bone-remodelling.
