Back Strain in the Workplace回到应变在工作场所
Only the common cold results in more lost work days than back strain.只是普通感冒，结果在更失去了工作回天，比应变。 Overexertion is responsible for 25% of all workplace injuries, according to the National Safety Council.过度负责的25 ％ ，所有工作场所受伤，根据国家安全局。 One worker in every 200 experiences an overexertion injury, indicates data compiled by the National Institute for Occupational Safety and Health (NIOSH).一名工人在每200经验1过度损伤，汇编的数据表明，由国家研究所的职业安全及健康（ niosh ） 。 Annually, overexertion injuries cost American business more than 12 million lost workdays and over $1 billion in compensation costs.每年，过度伤害美国的商业成本1200多万个工作日，损失超过10亿美元的赔偿费用。 The majority of overexertion injuries — 60% — result in back strain, particularly in the lower back.大多数过度受伤-6 0％ -结果在回到应变，特别是在低回。
Statistics show that one in five disabling workplace injuries are back injuries and that more than 25% of workers’ compensation claims are for back injuries.统计数字显示，一在五停用工作场所受伤个案，都是因背部受伤和25 ％以上的工人的赔偿索赔是背部受伤。 Back strain occurs when the back muscles are overused or ligaments and tendons are overstretched.回到应变发生时，背部肌肉是过度或韧带和肌腱是过度。 Recovery can be lengthy; and once damaged, the back is particularly susceptible to re-injury.复苏可以冗长;一旦损坏，回，尤其是容易再度受伤。
Back injuries most often occur during lifting, pulling, pushing, carrying, bending or twisting activities.背部受伤最常发生在起重机械，拉，推，携带，弯曲或扭活动。 These are the same activities most likely to be carried out by workers on a daily basis.这些都是同样的活动最有可能被所进行的工人对每日的基础。 According to OSHA studies, preventive measures that include weight restrictions on loads and personnel safety training have proved inadequate in reducing injuries.根据职业安全与卫生署研究，预防措施，包括重量限制对载荷和人员的安全培训证明不够，在减少受伤。 However, coupling preventive measures with ergonomically designed equipment can significantly reduce the incidence of back injuries in the workplace.然而，耦合的预防措施与符合人体工程学设计，设备，可显着降低发病率背部受伤在工作场所。
By studying the actions used to complete a task, ergonomic engineers are able to design equipment that eliminates or minimizes lifting, pulling, pushing, carrying, bending and twisting actions.通过学习行动，用来完成一项任务，人体工学设计工程师能够设计，设备，消除或减少起重机械，拉，推，携带，弯曲和扭曲的行动。 Ergonomic cart puller equipment工效学车牵引设备 that reduces the potential for overexertion or extension reduces the risk of back injury.减少过度的潜力，减少或延期的风险，背部受伤。
