Musculoskeletal modeling

Definition

Musculoskeletal modeling is a computational approach used to simulate the mechanical behavior of the human musculoskeletal system, which includes bones, muscles, tendons, and ligaments. This method allows researchers and engineers to analyze movement, assess forces acting on the body, and predict how changes in anatomy or loading conditions affect performance. By creating detailed models of human anatomy and movement, it provides insights into biomechanics and helps in the design of interventions and devices for rehabilitation and injury prevention.
