The effects of upper limb loading on spinal shrinkage during treadmill walking
European Spine Journal, 06/04/2012
Watson H et al. – Results suggest that the body adopts less anterior lean with an immediate load–bearing demand, to decrease the necessary extension moment generated by the spinal extensors for spinal stability. Further postural alteration in the same direction is observed with prolonged loading. In combination with lumbar spinal shrinkage, such postural changes are likely to increase the loading on the facet joints and subsequently unload the discs which may be beneficial for those with low back pain.
