 Background & Objectives : Currently, work-related musculoskeletal disorders are a major occupational health concern. This study tried to evaluate the risk factors of musculoskeletal disorders by the assessment of repetitive tasks (ART). It also sought to determine the effects of an ergonomic intervention on the mentioned risk in a manufacturing company .

 Methods: In this study, 60 production line workers were randomly selected. The data was collected by using a demographic questionnaire and the ART. The intervention was implemented for 39 cases. Data were analyzed in SPSS.

 Results: The initial evaluations suggested low, moderate, and high levels of risk in 21.7, 48.3, and 30.0 of the participants, respectively. Re-assessments after the intervention showed that the frequency of low-risk individuals increased from 30.70 before the intervention to 53.85 after the intervention. On the other hand, comparisons between the rates before and after the intervention revealed reductions in the frequency of moderate risk (64.10 vs. 43.59) and high risk (5.2 vs. 2.56). These changes were all significant.

 Conclusion: In most cases, the initial ergonomic risks were not at an acceptable level. In fact, most workers were at moderate level of risk. Since many workers in the assembling industry suffer from musculoskeletal disorders, low-cost eengineering and management measures can be taken to reduce the level of risk .
