This project intends to assess the feasibility of using inertia-tracking system (i.e. XSens) to provide input data for modelling in OpenSim. We managed to adapt the LaiArnold2017 model to the 'T-pose' used for XSens to scale their biomechanical model. We also updated the segment masses to follow deLeva 1996 antropometric data.


This project intends to assess the feasibility of using inertia-tracking system (i.e. XSens) to provide input data for modelling in OpenSim. We managed to adapt the LaiArnold2017 model to the 'T-pose' used for XSens to scale their biomechanical model. We also created the virtual markers exported at the C3D files from MVN Studio into OpenSim .xml files. In addition, we developed scripts in order to convert data from XSens in the TRC files required for scaling, based on work from Felipe Alvim and others.
In order to convert the data from XSens to OpenSim, the following steps are required:
1- Export the data from MVN Studio as C3D assigning the first frame as the 'T-pose';
2- Use the codes provided in this project to convert the C3D files into TRC (static and motion)

This project also allows you to export data from Kistler Bioware software to .mot files, if you wish to do Inverse Dynamics. For this step, you have to export the data as .txt files and use these files into the program block associated with the Bioware convertion.
