Objectives.  The increasing prevalence of musculoskeletal disorders (MSDs), especially in the neck and upper limbs, among office workers is an important issue related to health and job productivity. The present study aimed to evaluate the effect of an ergonomics training intervention on MSDs, quality of work-life and occupational psychosocial stresses among office workers.  Methods.  This quasi-randomized trial study was conducted in Isfahan, Iran in 2019. Outcome measures were measured in a follow-up period of 1, 3 and 6 months after the intervention. The results were analyzed using repeated-measures analysis of variance.  Results.  The interventions performed had a significant effect on neck, left shoulder, right wrist and left thigh discomfort. These interventions also had a significant effect on social support and physical job demands. Significant changes were detected in quality of work-life, chance of growth and security, social integration in organization and social relevance of work in life, although these changes decreased in quality of work-life. No significant differences were detected in the other measured outcomes.  Conclusion.  The implementation of ergonomic interventions was effective in reducing MSDs in the neck and upper limbs. It is recommended to conduct continuous training courses to control the risk of ergonomic factors affecting body discomfort.
