The objective of this investigation was to use published literature to demonstrate that specific changes in workplace biomechanical exposure levels can predict reductions in back injuries. A systematic literature review was conducted to identify epidemiologic studies which could be used to quantify relationships between several well-recognized biomechanical measures of back stress and economically relevant outcome measures. Eighteen publications, describing 15 research studies, which fulfilled search criteria were found. Quantitative associations were observed between back injuries and measures of spinal compression, lifting, lifting ratios, postures, and combinations thereof. Results were intended to provide safety practitioners with information that could be applied to their own work situations to estimate costs and benefits of ergonomic intervention strategies before they are implemented.
本调查的目的是利用已发表的文献来证明工作场所生物力学暴露水平的特定变化能够预测背部损伤的减少。进行了一项系统的文献综述,以确定可用于量化几种公认的背部压力生物力学测量指标与经济相关结果测量指标之间关系的流行病学研究。共找到18篇描述15项研究的出版物,这些出版物符合检索标准。观察到背部损伤与脊柱压缩、提举、提举比率、姿势及其组合测量指标之间存在定量关联。研究结果旨在为安全从业人员提供信息,以便他们在实施人体工程学干预策略之前,将这些信息应用于自己的工作场景中,从而估算这些策略的成本和效益。
