A Conceptual Model of Oxerexertion, Safety, and Risk of Injury in Occupational Settings
提出了一个基于疲劳的过度用力、安全边际与工作相关受伤风险的通用概念模型，通过力量、时间暴露和空间运动变量识别和量化物理风险因素，为后续验证研究提供框架。
A conceptual generic model for fatigue-mediated overexertion, margin of safety, and job-related risk of injury is proposed. The model has been built with the variables of force, effective exposure in time domain, and motion of the exertion in space. With the proposed model, the physical risk factors can be identified and quantified. It also allows one to gauge a relative contribution of various integral factors involved in fatigue-mediated occupational injuries. Although the model is based on established relationships between the job variables (strength [force], frequency-duration of exposure, recovery from exposure, and range of required motion) and the injuries sustained, it has not been validated within any single study. The model provides a framework for numerous validation studies. With availability of more information through such studies, the model can be appropriately refined for accuracy of its prediction.
