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.
