This study investigated the effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) in Video Display Terminal (VDT) workers. 100 VDT workers were selected to receive the ergonomic intervention, whereas 100 were assigned to a control group. The two groups were then crossed-over after 30 months from baseline. Follow-ups were repeated at 5, 12, and 30 months from baseline and then at 6 months following crossover.
Work-related posture and LBP point-prevalence using the Rapid Entire Body Assessment method and a Pain Drawing, respectively. The ergonomic intervention at the workstation improved work-related posture and was effective in reducing LBP point-prevalence both in the first study period and after crossover, and these effects persisted for at least 30 months. In conclusion, our findings contribute to the evidence that individualized ergonomic interventions may be able to improve work-related posture and reduce LBP for VDT workers.
本研究旨在探讨工作站人体工程学干预措施对视频显示终端（VDT）作业人员与工作相关的姿势和下背痛（LBP）的有效性。选择 100 名 VDT 工人接受人体工程学干预，而另外 100 名工人则被分配到对照组。30 个月后，两组进行交叉。从基线开始，分别在 5、12 和 30 个月以及交叉后 6 个月进行随访。
使用快速全身评估方法和疼痛绘图分别评估与工作相关的姿势和 LBP 的点患病率。在工作站实施的人体工程学干预措施改善了与工作相关的姿势，并在第一研究期间和交叉后有效降低了 LBP 的点患病率，这些效果至少持续了 30 个月。总之，我们的研究结果表明，个体化的人体工程学干预措施可能能够改善 VDT 工人的与工作相关的姿势并减少 LBP。
