Hi, I'm simulating ascending and descending stairs in Opensense by IMU. But I don't know how to get the lower limb joint angle from the reverse motion. Are there any formulas that can be used to calculate the joint angle of the lower extremity? What is the program that implements these calculation? ...

Hi, I am using OpenSim4.2 to some walking simulation. In the beginning, the output looks like a walking simulation,i can see the knee angle change. But now,when i simulate walking again,the knee angle goes to zero,so the simulation results could be wrong.Can you tell me which step I wrong in? Thank ...

Hi, I am using OpenSim4.2 to some stair ascend and descend simulation. I collected IMU data by Xsens and used the colibration algorithm in the example,but the orientation of pelvis is invariable. Can I make the model move like stair ascend and descend( the pelvis can move, the model don't rotate abo...

Hi guys: I am working with Xsens sensors trying to get my data to read into Opensense (using Matlab 2017b scripting on windows 10).I can get the example data to work, however it seems that the Xsens csv files are now output in a different configuration than in the example data. I have tried making m...
