Hi there,

I am working with the GH Bergmann Model and I am looking at the GH joint reaction force at the moment.

- I don’t really understand how the Ftotal in the coordinate system of the Humerus (to compare to results with Bergmann)is calculated:

-Main-file:

GHReaction=

(Model.HumanModel.Right.ShoulderArm.Seg.Humerus.gh.Bergmann.Axes’*Model.HumanModel.Right.ShoulderArm.Jnt.GHReactions.ResultanForce.FTotalLocal’)’;

If I understand it right, FtotalLocal is in the local coordinate system of the Scapula, to calculate Ftotal in the coordinate system of the Humerus, don’t you have to take FtotalGlobal instead of FtotalLocal?

Thanks for your answer!
