I am not sure where you read that paragraph so I don't know if it applies to the Joint Moment Measures.
Anyhow, I made a mistake in my first post and you can just ignore that post.
The Joint moment measures are defined in the
The file contains
AnyForceMomentMeasure2 classes of all the measures.
Be aware that there are two versions for some joint; one that measure the forces and moments without contributions from the joint reaction and one with it.
The ones named "NetMomentMuscles" only computes forces and moments based on the muscles that span the joint. These are used to construct the joint moments you find under
Main.HumanModel.BodyModel.SelectedOutput.Right.ShoulderArm.JointMomentMeasure and you can see in the code to what reference frame the output moment in expressed.
for instance the ElbowPronation is transformed from global coordinates into the local radius.ps2.rotnode frame with these lines:
//Make transformation to the radius.ps2.rotnode coordinate system
I hope this helps a little.
Remember that the moments expressed in the global reference frame are also available in the
M variable of the
