Abstract: (1233 Views)
Objectives: Nowadays, workers are less mobile and more sedentary due to the use of modern technologies in the workplace, and the complications resulting from static work and fixed posture have caused numerous disorders, including musculoskeletal disorders. This study was conducted to evaluate the comfort and usability of the ergonomic sit-stand desk converter with the aim of preventing disorders caused by constant sitting in workers.
Methods: 30 employees and faculty members of a university voluntarily participated in this study and provided informed consent. After the necessary explanations, subjects were provided with two researcher-created questionnaires ( Local Perceived Discomfort (LPD) and Sit-Stand Desk Converter Usability Questionnaire (SSDCUQ)), two methods of posture analysis, two methods of Workstation evaluation and general satisfaction along with 20-8-2 software and an ergonomic desk converter. After the test period, the data was analyzed using SPSS version 22 software and statistical tests such as mean, standard deviation, Spearman's rank correlation coefficient and Pearson correlation coefficient.
Results: The overall mean LPD in the different body parts was 0.48 ± 0.87, indicating that the converter functions in the range of no problem to very little discomfort. The average overall satisfaction with the function of the converter was 3.18 ± 1.08 ,which is in the medium to good range. When analysing the different sitting and standing postures, a significant correlation was also found between the different situations of using the converter (P<0.0005), which indicates an improvement in sitting and standing posture while using the converter.
Conclusion: Height-adjustable workstations are a good choice to reduce sitting time and improve posture. Despite the improvement in sitting and standing posture when using the converter, there are limitations, such as ignoring the software warnings for sitting and standing in the mechanical converter studied.
