ارزیابی اثربخشی مداخلۀ ارگونومیک ایستگاه کار بر دردهای اسکلتی ـ‌ عضلانی در گروهی از کارکنان اداری

Background: The working station has a major impact on the musculoskeletal disorders, therefore a considerable attention to working station staff is of importance. The aim of this study was to investigate the effect of working station on musculoskeletal disorders among administrative staff. Methods: 30 administrative staff participated in this analytical descriptive study. Data was collected using Nordic Musculoskeletal Disorders Questionnaire (NMQ) in ergonomic design intervention of three working stations (sitting, standing-and-sitting, standing) before and after of intervention. Moreover, a t-test and multiple regression were used to analyze the data. Results: The average (standard deviation) of the age and work record of 30 participating employees were 44.3 (5) and 20 (5) years, respectively. There was a significant correlation between the type of working station before and after the intervention, with the expression of musculoskeletal disorders (P=0.02). There was also a significant relationship between variables of musculoskeletal disorders in the shoulders, necks, waist and hands at different working stations. However, there was a significant relationship between age, work experience and BMI index with musculoskeletal disorders. Conclusion: According to the results of this survey the best working station is a sitting-and-standing. Therefore, by changing the type of working stations, musculoskeletal discomfort of the employees will be reduced appropriately.
