Back Strain in the Workplace回到應變在工作場所
Only the common cold results in more lost work days than back strain.只是普通感冒，結果更失去了工作，日子比回應變。 Overexertion is responsible for 25% of all workplace injuries, according to the National Safety Council.過度使用是負責任的百分之二十五，所有工作場所受傷，根據國家安全局的問題。 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經驗作為一個過度損傷，表明數據編制，由國家研究所，職業安全及健康（國家職業安全衛生） 。 Annually, overexertion injuries cost American business more than 12 million lost workdays and over $1 billion in compensation costs.每年，過度使用受傷的代價，美國商業有1200多萬個工作日的損失超過10億美元的補償費用。 The majority of overexertion injuries — 60% — result in back strain, particularly in the lower back.大多數的過度傷害-6 0％ -結果在返回應變，特別是在降低。
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.統計表明，每5個致殘工傷是背部受傷，並說， 25 ％以上的工人賠償索賠是背部受傷。 Back strain occurs when the back muscles are overused or ligaments and tendons are overstretched.回到應變發生時，背部肌肉使用過度，或韌帶和肌腱都過度緊張。 Recovery can be lengthy; and once damaged, the back is particularly susceptible to re-injury.回收可以被冗長;一旦損壞，但回來是特別容易再度受傷。
Back injuries most often occur during lifting, pulling, pushing, carrying, bending or twisting activities.背部受傷最常發生在起重，拉，推，攜帶，彎曲或扭活動。 These are the same activities most likely to be carried out by workers on a daily basis.這些都是同樣的活動最有可能實施，由工人每天都在發生。 According to OSHA studies, preventive measures that include weight restrictions on loads and personnel safety training have proved inadequate in reducing injuries.根據職業安全與衛生署研究，預防性措施，包括重量限制載荷和人員的安全培訓證明不夠，在減少傷亡。 However, coupling preventive measures with ergonomically designed equipment can significantly reduce the incidence of back injuries in the workplace.然而，耦合預防措施與人體工學設計，設備，可顯著降低發病率的背部都有傷，在工作場所。
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.要通過學習行動，用來完成一項工作，符合人體工程學的工程師能夠設計設備，是消除或降低起重機械，拉，推，攜帶，彎曲和扭曲的行動。 Ergonomic cart puller equipment人體工學購物車牽引設備 that reduces the potential for overexertion or extension reduces the risk of back injury.這減少了可能為過度或擴建降低風險的背部受傷。
