Background: The design and manufacturing process in electronic companies is the most time consuming work behind computers. Because of the high prevalence of musculoskeletal disorders in computer users, researchers need to identify risk factors and ergonomic problems and ways to reduce them.
Methods: This study was a descriptive-analytical study and was conducted as an intervention in Behpajooh engineering company in Isfahan. Statistical sampling was done by global sampling (31 people). The Nordic questionnaire and the Rapid Office Strain Assessment (ROSA) were used to evaluate the risk factors of ergonomics. Data analysis was performed by using McNemar and Wilcoxon's non-parametric tests and using SPSS software.
Results: The results of the Nordic questionnaire, before ergonomic intervention, the frequency of problems in elbow is zero, in waist, upper back, neck and shoulders is 45-38%. Evaluation of Ergonomic Risk Factors derived from the Rapid Office Strain Assessment before intervention showed 35.5% (11 people) at low risk, 38.7% (12 people) in the warning zone and 25.8% (8 people) in the area requiring ergonomic intervention. Statistical analysis of ergonomic interventions showed that the number of people in the area of warning and necessity are less than the number of people before intervention.
Conclusion: The most musculoskeletal disorders were reported in the neck, lower back, upper back and shoulders. Statistical results after ergonomic intervention indicate a decrease in these disorders. The results led to the understanding that the risks in electronic companies could be reduced by ergonomic interventions. Implementation of ergonomic interventions based on engineering, management and educational proceeding can be effective in reducing musculoskeletal disorders.
