I am a student of biomechanical engineering and I have used the dataset of the 4th competition of the Grand Challenge Competition to Predict In Vivo Knee Loads for my master thesis an I have some questions on the data of the load cells. Is the formula for computation of joint contact force suitable ...

Hi, thank you for your reply. The issue is that according to Charlton 2001: “Application of spherical and cylindrical wrapping algorithms in a musculoskeletal model of the upper limb” the moment arm of a muscle is computed from the change of length of the muscle for each timestep. Muscles, which act...

Hi, I ve been trying to find out how the wrapping of the muscle path affects the calculation of moment arm and the muscle force using the OpenSim documentation. How the force of the muscle is calculated in an inverse dynamics approach, where static optimization is used? Is the “arc” on the wrapping-...

Hello, I am using 4th Grand Challenge data for my research. I have some question of using the EMG Data to validate the calculated Muscle Forces of an inverse dynamics model. Which processing I have to perform to use the data to calculate an activation signal out of the EMG raw data? Do you know reco...

Hello,
how the markers are implemented in the multibody model? Which dataset should be used for the validation of the multibody model? Which purpose have the calibration datasets?
