Presidential Young Investigators Award: Instruments for Measuring Exposure to Repetitive Manual Work

这项工作的主要目标是在人体工程学领域进行基础和应用研究。具体目标包括：(1)推进理论，开发测量和评估重复性体力劳动中身体压力暴露的仪器和分析方法；(2)调查与暴露于这些压力有关的性能缺陷；(3)通过建立基于这些测量的暴露和工作设计指南来提高性能和预防伤害。工作场所的身体压力被认为是生产力下降、工作质量下降、操作人员不适、工人不满和伤害发生率增加的潜在原因。由于过度暴露在这些压力下而导致的残疾给工业带来了巨大的成本，包括医疗费用、工人赔偿、生产力下降、时间损失和人类痛苦。本研究的最终目标是制定有效的定量指导方针，以提高手工性能并保护工人免受有害的身体压力。

The major objective of this effort is to pursue basic and applied research in the area of ergonomics. Specific objectives include (1) advancing theory for developing instruments and analytical methods for measuring and assessing exposure to physical stress in repetitive manual work, (2) investigating performance deficits associated with exposure to these stresses, and (3) enhancing performance and preventing injuries by establishing exposure and job design guidelines based on these measurements. Physical stress in the workplace has been recognized as an underlying cause of decreased productivity, reduced work quality, operator discomfort, worker dissatisfaction, and increased incidence of injuries. Disabilities resulting from excessive exposure to these stresses incur significant costs to industry in the form of medical bills, worker's compensation, reduced productivity, lost time, and human suffering. The ultimate goal of this research is the development of effective quantitative guidelines for enhancing manual performance and protecting workers from harmful exposure to physical stress.
