Title: Estimating Joint Loads in OpenSim
Speaker: Matt DeMers, Stanford University
The talk is approximately 40 minutes, followed by an open Q&A session.

Webinar Handouts and Example Files

You can download the checklists for Static Optimization and Joint Reactions that Matt discussed during the webinar to find out more about using these tools for your own research. You can download the example files at Simtk.org (scroll down to "OpenSim Models and Examples").

Talk Synopsis:

Matt DeMers will discuss and demonstrate tools for estimating joint reaction loads in OpenSim. Since physiological joint reaction loads are dominated by the action of muscles, Matt will first describe how Static Optimization is used to estimate muscle forces from motion capture data. Then, he will discuss how the Joint Reaction analysis uses these muscle estimates to calculate resultant loads at the joints. Matt will next step through an exercise in OpenSim, applying these tools to an example trial of walking gait. He will use this practical segment to highlight some common pitfalls, troubleshooting approaches, and general best practices for estimating muscle and joint loads during gait.
