The role of exercise and posture in preventing low back injury.

Low back injury is a serious problem for U.S. industries, accounting for as much as one third of all workers' compensation payments. The number of low back injuries can be reduced effectively through the stressing of proper posture and the use of back care exercises. Body posture that maintains the spine's three natural curves decreases intradiscal stress. Back care exercises decrease the likelihood of low back injury by strengthening and adding flexibility to the spine's supportive structures.
