Subject-Specificity via 3D Ultrasound and Personalized Musculoskeletal Modeling

This study combines experimental-based and model-based methodologies for accessing in vivo musculoskeletal function in healthy individuals. We use ultrasound and dynamometer technologies to derive subject-specific muscle parameters including muscle isometric force, optimal fiber length and tendon slack length. We then assess the impact of subject-specificity on the electromyography-driven simulation of walking of the composite musculoskeletal system.
