Abstract
Introduction: The harmful ergonomic factors cause work-related musculoskeletal disorders. They annually cause a relatively high percentage of work-related absences, insurance indemnities, physical and mental discomfort, and ultimately workers' dissatisfaction and reduced productivity and production. To address these risks, ergonomics identifies human capabilities and capacities; moreover, it organizes and adjusts the devices and workstations and the environment appropriate for human beings
Methods: This study was descriptive-cross sectional. In this study, Nordic questionnaire was used to determine the prevalence of musculoskeletal discomfort and ROSA method was utilized to determine the risk level. After completing the forms and checklists, the data were analyzed by SPSS18 software.  Results: Based on the results of the study, the overall prevalence of musculoskeletal disorders was 60.7%. The prevalence of musculoskeletal disorders over the past 12 months (at least one impaired area) was 91.8%. The overall prevalence of musculoskeletal disorders (at least one impaired area) in the last 7 days was 0.82%.
Conclusion: Based on the results, the mean and standard deviation of ROSA score in the staff was 5.57 and 1.26. According to the results of the study, the necessity of ergonomic interventions in personnel training and the purchase of ergonomic equipment are prioritized.

Abstract
Abstract
Introduction: Musculoskeletal disorders are one of the most common injuries among computer users, which probably affect the quality of life (QOL) and efficiency.
Methods: In this descriptive-analytical study, 150 Nordic questionnaires were distributed among computer users in Hamedan province and a total of 110 questionnaires were collected. Later, 60 participants (female: n=20 and male: n=40) were evaluated based on the inclusion and exclusion criteria. Musculoskeletal disorders and workplace ergonomic principles were considered as independent variables and quality of life dimensions were investigated as the dependent variables. Rapid Office Strain Assessment (ROSA) was applied to evaluate workplace ergonomic, Nordic questionnaire was administered to evaluated musculoskeletal disorders, and SF-36 was used to assess QOL. Data were analyzed using SPSS software version 22. Independent t-test and Pearson correlation coefficient were also run to analyze the data.
Results: According to the findings, 3% of users were in the safe zone, 16% in the alert zone, and 78% in the danger zone. The findings also showed that the most common pain segments were neck pain (85%) and back pain (75%) in women, but neck pain (52%) and back pain (55%) in men. Additionally, the results showed that ergonomics of the workplace has a negative and significant relationship with the physical dimension of QOL (R=-0/26, P=0/042). Musculoskeletal disorders have a negative and significant relationship with the general health dimension (R=-0/29, P=0/022) and with the pain dimension of the QOL (R=0/29, P=0/022). Moreover, a negative and significant relationship was observed between QOL and BMI (R=-0/49, P=0/001).
Conclusion: Based on the results, workplace ergonomics has an effect on the incidence of musculoskeletal disorders and ultimately the QOL of computer users in non-office environments and computer services
