Having read your article Back to Basics (NCE 10 October) it seems to be making a mountain out of molehill of back pain.
The basic problem stems from the evolutionary process of adopting a posture creating compression in the spine. The best cure is to hang from a beam preferably by ones toes.
This may not be practical in an office.
Having suffered back pain in the past I offer this method of relief, to be carried out immediately pain is experienced: Lie down on a hard floor; pull knees up to the chest; roll from one side to side until relief is felt. Repeat as necessary.
