Abstract

Musculoskeletal simulations of movement are traditionally performed using rigid multibody models with simplified joint representations that do not account for the deformability and complex motion of biological tissues and articulations. However, several pathological conditions and treatments, such as osteoarthritis and total joint replacement, can be best investigated within a deformable modeling framework. Local tissue deformation is usually modeled with the finite element method that discretizes an arbitrary geometry into a mesh of deformable elements. While finite element models have been widely used to describe the tissue behavior at the organ/joint level (e.g. bone, knee joint), the interaction between this local level and the neuromuscular behavior at the whole-body scale is often neglected. We will present a conceptual overview of multi-scale musculoskeletal modeling, and two examples of multi-scale approaches in a sequential fashion that link the outputs from a multibody OpenSim musculoskeletal simulation to joint-level deformable finite element models.

Webinar highlights:

  • Conceptual overview of multi-scale musculoskeletal modeling.
  • Presentation of two examples of the multi-scale sequential modeling approach that links multibody simulations to deformable finite element models.
