Objective

Compare musculoskeletal discomfort, productivity, postural risks, and perceived fatigue for a sit-stand-walk intervention between two workstation configurations – one, individually customized for office workers according to ergonomic guidelines (Ergo-Fit); another, self-adjusted by office workers according to their preference (Self-Adjusted).

Methods

36 participants performed a 60-min computer typing task in both configurations using a within-participants, counterbalanced design. Musculoskeletal discomfort and perceived fatigue were reported through surveys; productivity was operationalized by typing speed and typing error; postural risks were assessed by RULA for seated work, and REBA for standing work.

Results

Musculoskeletal discomfort and perceived fatigue did not vary significantly between configurations. Postural risks for seated and standing work were significantly lower for Ergo-Fit configuration; productivity was significantly higher for Self-Adjusted configuration.

Conclusion

Use of Ergo-Fit configuration for a sit-stand-walk intervention can facilitate postural transitions and increase physical activity, while enabling neutral postures in seated and standing work to minimize postural risks.

在基于计算机的工作的坐-站-步行干预中，工作站配置对肌肉骨骼不适、生产力、姿势风险和感知疲劳的影响。

目标

比较两种工作站配置之间的坐-站-步行干预的肌肉骨骼不适、生产力、姿势风险和感知疲劳 - 一种，根据人体工程学指南 (Ergo-Fit) 为办公室工作人员单独定制；另一种，由上班族根据自己的喜好自行调整（Self-Adjusted）。

方法

36 名参与者使用参与者内部平衡设计在两种配置中执行了 60 分钟的计算机打字任务。通过调查报告了肌肉骨骼不适和疲劳感；通过打字速度和打字错误来提高生产力；RULA 评估了坐着工作的姿势风险，REBA 评估了站立工作的风险。

结果

肌肉骨骼不适和疲劳感在不同配置之间没有显着差异。Ergo-Fit 配置的坐姿和站立工作的姿势风险显着降低；自调整配置的生产率显着提高。

结论

使用 Ergo-Fit 配置进行坐-站-步行干预可以促进姿势转换并增加身体活动，同时在坐姿和站立工作中实现中性姿势，以最大限度地降低姿势风险。
