OpenSim is a powerful and freely available tool for modeling and simulation of movement. Watch the video below to get an overview of the project and see how OpenSim can be used to help plan surgery for children with cerebral palsy.

Musculoskeletal modeling and dynamic simulation have recently emerged as powerful tools to uncover the biomechanical causes of movement abnormalities and to design improved treatments. Starting in 2006, we developed powerful, freely available software for simulating human movement, OpenSim. Users of this technology address fundamental issues in movement science and focus on critical areas of rehabilitation medicine, including stroke, spinal cord injury, cerebral palsy, prosthetics, orthotics, and osteoarthritis.

These projects are hosted through our sister site SimTK.org, a development environment and home for hundreds of biomedical research projects and teams.

OpenSim in Action

The Nike commercial during the 2017 Super Bowl includes footage from OpenSim and our lower limb model.

The model appears around the 25-second mark.
