Hi there,

I highly recommend taking pictures and/or video of static postural stance, and then during golf swing.

Have the patient uncover themselves enough so that you can see trunk action, and hamstrings, and as many muscles as you can during this activity. You may be surprised by what you find. Then take the same golf swing and ask them to repeat it to their other side (obviously their weaker and perhaps less efficient side), but it will help spot any differences. You may find that along witht he stiffness in the spine, there is rapid contraction of the obliques which may be promoting spasm, or the lat dorsi, which is related across a muscular sling to the hamstrings.

Ideally, stiffness aught to be decreased, but in relation to the type of overload/activity the patient performs. As well this posture also need be taken in reference to the specific movement pattern as Hallamshire mentioned.

Regards
