Thank you!

Re: Left-Right Data Mismatch in Shoulder Range of Motion Test

Hi Matt, Yes, both of them had the same settings. Thanks for pointing out the .xml file, as I had all the default weights set to 1.0 for the two plots in my previous reply. Now importing the ISB IK shoulder .xml file and running it twice, I am getting the following: Screenshot 2024-12-09 at 12.55.21...

Re: Left-Right Data Mismatch in Shoulder Range of Motion Test

Hi Matt, Yes, it should be the ISB Shoulder (LaiUhlrich2022). Below are the plots from the same video recomputed twice using IK in OpenSim for comparison: While the left-right arm mismatch is not as drastic as on the OpenCap kinematics dashboard from my previous forum post, it is still significant. ...

Left-Right Data Mismatch in Shoulder Range of Motion Test

I'm analyzing data from a shoulder range of motion test where participants simultaneously move their left and right arms in sync. The test includes a calibration move (an arm punch motion) followed by repeated movements of both arms. The a graph of the dashboard kinematics is attached. During the sy...

Re: Opencap muscle upper limb

How would one add muscles to the upper body of the unscaled version of the LaiUlrich2022.osim model?

In particular, I am integrate the existing Upper Extremity Kinematic Model (https://simtk.org/projects/up-ext-model), which contains a .jnt and .msl file. Thank you!

Obstructions in Video

Will I be able to capture video that has obstacles or obstructions? For example, capturing the video of someone operating a hand-powered wheelchair with part of the arm obstructed from the camera at times.

Thanks! :)
