The ankle plantarflexor muscles play an important role in human walking as they provide propulsion during the push-off phase. Simulations in which kinematics are generated de novo, commonly known as predictive simulations, can provide insights into gait pathologies resulting from deficits in these muscles. In this video, Stanford University’s Carmichael Ong discusses a framework for predictive simulation, along with the model he and his team used, to generate realistic motions of walking at a wide range of speeds. Ong also discusses how they systematically introduced plantarflexor deficits, specifically weakness and contracture, into their model and analyzed the resulting gait patterns.

A preprint titled "Predicting gait adaptations due to ankle plantarflexor muscle weakness and contracture using physics-based musculoskeletal simulations" (https://doi.org/10.1101/597294) provides more details of the study and is available on bioRxiv.
