摘要：AIM AND BACKGROUND: Studies show that the risk of musculoskeletal disorders (MSDs) among computer users is more than the other occupations. The present study aimed to determine the effect of educational intervention based on the “stages-of-change” model on practicing the correct posture to reduce MSDs among computer user staff of Tehran University of Medical Sciences (TUMS). METHODS: This is a quasi-experimental study which was carried out on 176 staff of TUMS. The study population was divided into two case and control groups, each including 88 participants. A self-structured as well as a standard questionnaire was used to collect the data. Data then were analyzed using descriptive and analytical tests. RESULTS: There was no significant difference between both groups in terms of mean score of stages of change, perceived benefits and barriers, self-efficacy, and processes of change before the intervention. However, the mean score of these variables increased for case group 3 months after the intervention. In addition, case group participants reported lower MSDs in their neck, lower back, elbow, and knee compared to control group. CONCLUSION: Ergonomic educational intervention based on the “stages-of-change” model has a positive impact on reduction of MSDs. Therefore, these disorders can be decreased through reducing working hours, changing the work conditions in accordance with ergonomic principles, dedicating some time for staff exercise, and holding educational courses for the personnel.
