Modelling of architectural-informed and activation-driven contractions of the human M. tibialis anterior

PN 2-8

Project description

The aim of this project is to develop and validate an architectural-informed and activation-driven 3D muscle model of human tibialis anterior. Therefore, a new method will be developed to determine 3D muscle architecture during dynamic muscle contractions using a custom-build ultrasound scanning device. Experimentally determined constitutive relationships are integrated into a continuum-mechanical constitutive law.
