This study was designed to determine the effect of multimodal intervention and the prevention of back injury, and to evaluate the adverse side effects of using a lumbosacral corset in the workplace. Subjects were 90 male warehouse workers randomly selected from over 800 employees at a grocery distribution center. Subjects were assigned to three groups: true controls, no back school, no brace orthoses; back school only; and back school plus wearing a custom molded lumbosacral orthosis. Comparisons of pre-testing and 6-month follow-up post-testing for abdominal strength, cognitive data, work injury incidence and productivity and use of health care services were evaluated. Controls and training-only group showed no changes in strength productivity or lost time. Orthoses and training-group showed no changes in strength productivity or accident rate; however, they showed substantially less lost time. This study supports the concept of using education and prophylactic bracing to prevent back injury and reduce time loss. It appears that the use of intermittent prophylactic bracing has no adverse affects on abdominal muscle strength and may contribute to decreased lost time from work injuries.
本研究旨在确定多模式干预对预防背部损伤的效果，并评估在工作场所使用腰骶部束腹带的不良副作用。研究对象是从一家食品配送中心800多名员工中随机选取的90名男性仓库工人。研究对象被分为三组：真正的对照组，不参加背部康复课程，不使用矫正支具；仅参加背部康复课程；参加背部康复课程并佩戴定制的腰骶部矫形器。对腹部力量、认知数据、工伤发生率、生产力以及医疗服务使用情况进行了预测试和6个月随访后的测试比较评估。对照组和仅接受训练的组在力量、生产力或误工时间方面没有变化。使用矫形器并接受训练的组在力量、生产力或事故率方面没有变化；然而，他们的误工时间大幅减少。本研究支持利用教育和预防性支具预防背部损伤并减少时间损失的理念。间歇性预防性使用支具似乎对腹部肌肉力量没有不良影响，且可能有助于减少工伤导致的误工时间。
