Abstract

BACKGROUND

Manual assembly workers are exposed to risk factors of musculoskeletal disorders. The most important risk factor among the workers is static and awkward posture. This study aimed to the ergonomic design of manual assembly workstation using Digital Human Modeling (DHM).

METHODS

This cross-sectional study was conducted among manual assembly workers. Data was gathered 1) demographic/occupational questionnaire, 2) The Persian version of the Nordic General Questionnaire (P-NMQ), 3) Rapid Upper Limb Assessment (RULA) using Kinect sensor, 4) Hierarchical Task Analysis (HTA), 5) Idea Rating Sheet (IRS), 6) Anthropometric data of the participants, 7) CATIA software and RULA technique.

RESULTS

The results of the evaluations showed that in the design of most workstations of assemblers in Shiraz electronics industries, complete ergonomic principles were not observed, and the implementation of targeted ergonomic interventions in them is necessary.

CONCLUSION

The prevalence of musculoskeletal symptoms is high among manual assembly workers. The RULA technique showed that the designed manual assembly workstation using DHM effectively could improve the subjects' awkward postures.

摘要

背景

手动装配工人面临肌肉骨骼疾病的风险因素。在工人中最重要的风险因素是静态和不自然的姿势。本研究旨在使用数字人体建模（DHM）进行手动装配工作站的人体工程学设计。

方法

这是一项横断面研究，研究对象为手动装配工人。数据收集包括：1）人口统计学/职业问卷；2）北欧一般问卷（P-NMQ）的波斯语版本；3）使用 Kinect 传感器的快速上肢评估（RULA）；4）层次任务分析（HTA）；5）想法评分表（IRS）；6）参与者的人体测量数据；7）CATIA 软件和 RULA 技术。
