摘要

目的本研究的目的是量化和描述在矿区从事各种职业时肱骨和躯干所受到的人体工程学影响:来自 11 种不同职业的 13 名矿场工人安装了可穿戴传感器,以测量 1-4 个自然现场工作任务期间的躯干和肱骨运动学。计算每项工作任务的躯干弯曲/伸展和肱骨抬高第10、50、90和99百分位数、范围、保持中立和极端姿势的时间百分比、动作重复率、平均角速度以及以慢速和高速工作的时间百分比:结果:在不同的职业和工作任务中测出了不同程度的人体工程学暴露;然而,在许多结果中,家政工作始终是暴露程度最高的工作:结论:今后的工作应研究在被确定为高暴露的工作任务中减少体力需求的策略。

Quantifying the trunk and humeral postural demands of uranium mine site workers using wearable sensors.

Objective: The purpose of this study was to quantify and describe humeral and trunk ergonomic exposures across various occupations on a mine site.

Methods: Thirteen mine site workers from 11 different occupations were outfitted with wearable sensors to measure trunk and humeral kinematics during 1-4 natural on-site work tasks. Trunk flexion/extension and humeral elevation 10th, 50th, 90th and 99th percentiles, range, percent time in neutral and extreme posture, rate of movement repetition, mean angular velocity, and percent time working at slow and fast speed were calculated for each work task.

Results: Various degrees of ergonomic exposure were measured in the different occupations and work tasks; however, the housekeeping work was consistently the highest exposure task across many of the outcomes.

Conclusion: Future work should examine strategies for reducing the physical demand in work tasks identified as high exposure.
