A total of 574 active workers from six different industrial sites were categorised into four force repetitive exposure groups. Workers in low force-low repetitive jobs served as an internal comparison population for the three other groups. Videotapes and surface electromyography were used to estimate hand force and repetitiveness. The presence of cumulative trauma disorders (CTD) was determined by structured interview and standardised non-invasive physical examination. Only workers who had been working on the study jobs for at least one year at the time of evaluation were eligible for selection. Categorisation of jobs and identification of CTDs were carried out independently by investigators who were appropriately blinded to exposure and outcome. The analysis of associations between CTDs and exposure categories were performed using Mantel-Haenszel plant adjusted odds ratios and unconditional multiple logistic regression. Significant positive associations were observed between hand wrist CTDs and high force-high repetitive jobs. These associations were independent of age, sex, years on the specific job, and plant.
来自六个不同工业场所的574名在职员工被分为四个用力重复暴露组。从事低用力-低重复工作的员工作为其他三组的内部对照人群。通过录像带和表面肌电图来评估手部用力和重复性。通过结构化访谈和标准化的非侵入性体格检查来确定累积性创伤障碍（CTD）的存在。只有在评估时已在研究岗位上工作至少一年的员工才有资格入选。工作分类和CTD识别由对暴露和结果适当不知情的调查人员独立进行。使用Mantel-Haenszel工厂调整后的优势比和无条件多元逻辑回归对CTD与暴露类别之间的关联进行分析。在手-腕CTD与高用力-高重复工作之间观察到显著的正相关。这些关联独立于年龄、性别、在特定工作岗位上的工作年限和工厂。
