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.
腰背部损伤对美国各行业来说是个严重问题，在所有工伤赔偿中占比高达三分之一。通过强调正确姿势和进行背部护理锻炼，可有效减少腰背部损伤的数量。保持脊柱三个自然曲线的身体姿势能降低椎间盘内压力。背部护理锻炼通过增强脊柱支撑结构并增加其灵活性，降低了腰背部受伤的可能性。
