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.

目标。在办公室工作人员中，肌肉骨骼疾病 (MSD) 的患病率越来越高，尤其是在颈部和上肢，这是与健康和工作效率相关的重要问题。本研究旨在评估人体工程学培训干预对办公室工作人员 MSD、工作生活质量和职业社会心理压力的影响。方法。这项半随机试验研究于 2019 年在伊朗伊斯法罕进行。结果指标在干预后 1、3 和 6 个月的随访期内进行测量。使用重复测量方差分析对结果进行分析。结果。所进行的干预对颈部、左肩、右腕和左大腿的不适有显着影响。这些干预措施也对社会支持和体力工作需求产生了显着影响。在工作生活质量、成长和安全的机会、组织中的社会融合以及工作在生活中的社会相关性方面发现了显着变化，尽管这些变化降低了工作生活质量。在其他测量结果中未检测到显着差异。结论。人体工程学干预措施的实施有效地减少了颈部和上肢的 MSD。建议进行持续的培训课程，以控制人体工程学因素影响身体不适的风险。
