The Neuromusculoskeletal Modeling Pipeline: MATLAB-based model personalization and treatment optimization functionality for OpenSim by Claire V. Hammond, Spencer T. Williams, Marleny M. Vega, Di Ao, Geng Li, Robert M. Salati, Kayla M. Pariser, Mohammad S. Shourijeh, Ayman W. Habib, Carolynn Patten, Benjamin J. Fregly

“…An NMSM Pipeline use case is presented for an individual post-stroke with impaired walking function, where the goal was to predict how the subject’s neural control could be changed to improve walking speed without increasing metabolic cost. First the Model Personalization toolset was used to develop a personalized neuromusculoskeletal model of the subject starting from a generic OpenSim full-body model and experimental walking data (video motion capture, ground reaction, and electromyography) collected from the subject at his self-selected speed. …”
