Most ergonomics studies on office workstations evaluate the effects of an intervention only by subjective measures such as musculoskeletal pain and discomfort. Limited evidence has been provided regarding risk factor reduction in office environments through standardized methods assessments. The Rapid Office Strain Assessment (ROSA) tool can provide an estimation of risk factor exposure for office workers as a means by which the outcome of interventions can be quantified.
The aim of the study was to evaluate if ROSA scores reflect changes in risk factors after an ergonomics intervention among office workers.
Office workers (n = 60) were divided into two groups. The experimental group received a workstation intervention and the control group received no intervention. Changes in ROSA scores were compared before and after the intervention in both groups.
Statistically significant reductions in the ROSA final and section scores occurred after the intervention in the experimental group with (mean reduction of 2.9, 0.8 and 1.6 points for sections A, B and C, respectively). In contrast, no differences were detected in the control group (mean increase of 0.1 point for sections A and C and mean reduction of 0.1 point for Section B).
These findings show that ROSA scores reflect changes in risk factors after an ergonomics intervention in an office environment. Consequently, this tool can be used for identifying and controlling risk factors among computer workers, before and after interventions.
大多数关于办公工作站的人体工程学研究仅通过肌肉骨骼疼痛和不适等主观措施评估干预效果。通过标准化方法评估，有关通过办公环境减少风险因素的证据有限。快速办公压力评估（ROSA）工具可以为办公人员提供风险因素暴露的估计，作为量化干预措施结果的一种手段。
本研究旨在评估 ROSA 评分是否反映了办公人员接受人体工程学干预后的风险因素变化。
将 60 名上班族分为两组。实验组接受工作站干预，对照组不接受干预。比较两组干预前后 ROSA 评分的变化。
实验组的 ROSA 总分和各部分得分在干预后均显著降低（A、B、C 部分的平均降低分别为 2.9、0.8 和 1.6 分）。相比之下，对照组未检测到差异（A 和 C 部分的平均增加 0.1 分，B 部分的平均降低 0.1 分）。
这些发现表明，ROSA 评分反映了办公环境中人体工程学干预后风险因素的变化。因此，该工具可用于在干预前后识别和控制计算机工作人员的风险因素。
