So the golfer performed what motions of each section of the spine(black lines)in what plane(Yellow lines)as defined by the new location of joints(red dots) compared to the above "neutral" posture model?
Make sure you measure the angle between the Torso and the Upper Leg..you'll need it for future analysis...looks like this(>)

The way I understand this is... there ideally is little, if any change in the angle of the TORSO when one is bent over the ball, and throughout the Stroke. There is no BOB or SWAY. The different parts of the SPINE(cervical, thoracic, lumbar, sacral)however, DO CHANGE during a swing.
Tiger Woods, and Adam Scott would be obvious examples of this. Their cervical and thoracic angles obviously change from their Address angles, but the overall TORSO angles are very much the same as at Address.
Lagster....Now I'm smellin what you're steppin in!
You are absolutely correct here....Many golfers and golf professionals confuse the "Inclination of the Torso" as ...."THE SPINE ANGLE"...Huge mistake..HUGE!!!....I'd agree that while there should be no bobbing or swaying the "Inclination of the Torso" stays relatively stable for a relatively straight shot...
This is the "Inclination of the Torso"
It's not a matter of semantics...because the spine is not located where these markers and these planes intersect...
Very Important...Notice Above...the Neck(Cervical Spine) is moderately flexed forward .....
Contrary look below...
Is the Neck still flexed forward or is it really beginning to lateral bend to the right?
How about the upper torso?...LOOK....LOOK...LOOK!!!
Is Sam still in his waist bend or was the axis of rotation replaced by another axis of rotation and his torso is now rotating, extending and lateral bending?
BTW ...Yes the "Inclination of the Torso" is somewhat sustained...
BUT there are some serious changes going on....STUDY THE SEGMENT ANGLES!!!

Study the Segment Angles of the Torso and the Upper Leg...pay closed attention to the markers...remeber they are red dots!!!
Measure the angles formed by the right shoulder, right hip, right knee at address.....compare the same angles to the right shoulder, right hip and right knee at the End from the rear ..try the same for the left shoulder,left hip, and left lnee....Are they exactly the same? How is it these angles change...? Hey captain obvious ..the legs action influences the Sacral and the Lumbar Movements...then how is this affecting the other segments of the spine? HMMM... To deep for my rudimentary understanding!!!!!
Address:
End:
Clue: The axis of rotation changes at least 3 times not twice or just once
After Impact:

This is really interesting subject matter. Thanks for the great work Annikan. Your efforts are much appreciated.
Might need to learn a new language first before I can continue!.
