I recently got a combination sit/stand desk and I feel that when I stand I tend to move more overall, however, so "motionless" might be less of a factor. I sway back and forth a lot, or rock on my heels slightly, etc... I've found that breaking my day into about half sitting / half standing has been roughly optimal. I've been unable to stand for the entire day without a fair amount of ankle/foot pain.
