OpenGRF: free OpenSim API tool for Ground Reaction Forces prediction

OpenGRF is a free OpenSim tool built on the MATLAB API, designed to predict ground reaction forces (GRFs). The tool accepts as input a scaled or subject-specific musculoskeletal (MSK) model (.osim) and a kinematics file (.mot) containing the generalized coordinates. The output includes a GRFs file (.mot), which also provides the center of pressure (CoP).Key Features:- Versatile Applications: OpenGRF can analyze kinematics for any scenario, including complex movements such as burpees, by calculating simultaneous contact forces for both hands and feet.- Flexible Kinematics: While the preferred input is marker-based kinematics, OpenGRF is also compatible with markerless kinematics.- Simulation Efficiency: On average, simulations require 5 minutes per second of kinematic data.Note: OpenGRF is currently a work-in-progress project. We encourage you to test and use it for research purposes, but kindly refrain from citing it until the associated paper is published <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=3126#pack_2451">OpenGRF </a> : OpenGRF is a free OpenSim tool built on the MATLAB API, designed to predict ground reaction forces (GRFs).
