Inverse Dynamics, Joint Reaction Forces, and Loading | Prof Bill Baltzopoulos
Channel: Stuart McErlain-Naylor
Date: 2020-04-30

Lecture 11 of the Sports Biomechanics Lecture Series #SportsBiomLS 
Bill Baltzopoulos provides a discussion of the inverse dynamics approach used in biomechanics. This includes methods for the assessment of loading in the musculoskeletal system, an overview of modeling approaches, how to approach inverse dynamics, and a discussion of mechanical misconceptions / inverse dynamics terminology. The talk includes a series of recommendations for anybody using or reporting an inverse dynamics approach.
