What are the Upper Body Segment angles from Plug-in Gait?

The table below displays the Upper Body Segment angles from Plug-in Gait.

All Upper Body angles are calculate in rotation order YXZ.

As Euler angles are calculated, each rotation causes the axis for the subsequent rotation to be shifted. X’ indicates an axis which has been acted upon and shifted by one previous rotation, X’’ indicates a rotation axis which has been acted upon and shifted by two previous rotations.
