Best practice for analyzing shoulder motion using MoCap data with a reduced marker set

Main Forum

Hello AnyBody Forum,

I am planning to investigate shoulder motion using MoCap data, focusing on kinematics and muscle forces. Since my interest is limited to the shoulder, I would like to reduce the marker set.

I’m starting from the full-body MoCap example model, and I see two possible approaches:

  1. Delete the lower body from the model.
  2. Keep the lower extremities but use drivers to fixate the lower body joints.

What would be the best practice for analyzing shoulder motion using MoCap data when a full-body marker set is not needed?

Hi Christoph

Welcome to the AnyScript Forum!

I would recommend switching off the leg model. You can add the following lines in the BodyModelConfig.any file that you can find through the LabSpecificData.any file:

#define BM_LEG_LEFT OFF
#define BM_LEG_RIGHT OFF

Please note the trunk and head can't be switched off, so please include markers for the trunk and head. And the arm, of course :slight_smile:

Best regards,
Dave
