While supporting any and all well meaning people who want to help back pain, I find myself at odds with one recommendation of the forth coming “back in the office” campaign promoted by the Charity Back care (6th -12th October 2014)
Whilst i endorse most of the aims of this campaign

• Stand not Sit while you work
• Stretch your back at your desk at least every half hour
• Set your workstation just right
• Ergonomic furniture, a hype or a necessity?
• Use headsets and stop straining those neck muscles!
• Take regular breaks especially if you work long hours
• Employers guidelines

I think based on current research, that the “stretch your back ” suggestion, is probably  best  treated with caution
