Abstract

Evaluate the impact of a 6-month sit-stand desk (SSD) intervention on office workers' regional musculoskeletal discomfort (MD) and overall post-work fatigue (PWF) compared to a control group. A two-arm (1:1) clustered randomised controlled trial including 38 participants (aged 24-60 years, 77% women) assigned to intervention or control groups. The intervention, spanning 6 months, involved psychoeducation, motivational prompts, and SSD. The control group maintained standard working conditions. MD was assessed using the Nordic Musculoskeletal Questionnaire, and PWF with the Need for Recovery Scale. ANCOVA was employed to compare groups, adjusting for covariates, with 5% significance. The intervention group reduced overall MD (p = 0.018) and PWF (p = 0.013), while the control group showed no changes. However, no time*group interactions were found (p > 0.05). A 6-month SSD intervention alleviated office workers' MD and PWF, suggesting benefits from increasing standing time by at least 30 minutes/day. Future investigations must explore individual heterogeneity in response to SSD.

为期 6 个月的坐立办公桌干预措施对办公室工作人员区域性肌肉骨骼不适和整体工作后疲劳的影响：分组随机对照试验。

与对照组相比，评估为期 6 个月的坐立办公桌（SSD）干预措施对上班族区域性肌肉骨骼不适（MD）和整体工作后疲劳（PWF）的影响。这是一项双臂（1:1）分组随机对照试验，38 名参与者（24-60 岁，77% 为女性）被分配到干预组或对照组。干预为期 6 个月，包括心理教育、动机提示和 SSD。对照组则保持标准的工作条件。MD 采用北欧肌肉骨骼问卷进行评估，PWF 采用需要恢复量表进行评估。采用方差分析对各组进行比较，调整协变量，显著性为 5%。干预组减少了总体 MD（p = 0.018）和 PWF（p = 0.013），而对照组没有变化。但是，没有发现时间*组间的交互作用（p > 0.05）。为期 6 个月的 SSD 干预可减轻上班族的 MD 和 PWF，表明每天增加至少 30 分钟的站立时间可带来益处。未来的研究必须探索个体对SSD反应的异质性。试验注册：https://doi.org/10.17605/OSF.IO/JHGPW。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
