Ehsanollah Habibi . Shiva Soury Journal Article 2023 01 26 Background: Prevalence of work‑related musculoskeletal disorders (WMSDs) is high among<br />computer users. The study investigates the effect of three ergonomic interventions on the<br />incidence of musculoskeletal disorders among the staff of Isfahan Province Gas Company,<br />including training, sport, and installation of software. Materials and Methods: The study was<br />performed in the summer of 2013 on 75 (52 men, 23 women) Isfahan Province Gas Company<br />employees in three phases (phase 1: Evaluation of present situation, phase 2: Performing<br />interventions, and phase 3: Re‑evaluation). Participants were divided into three groups (training,<br />exercise, and software). The Nordic Musculoskeletal Questionnaire (NMQ) and rapid upper<br />limb assessment (RULA) were used. Data collected were analyzed using SPSS software and<br />McNemar test, t‑test, and Chi‑square test. Results: Based on the evaluations, there was a<br />decrease in musculoskeletal symptoms among the trained group participants after they received<br />the training. McNemar test showed that the lower rate of pain in low back, neck, knee, and<br />wrist was significant (P < 0.05). The results obtained from the RULA method for evaluation<br />of posture showed an average 25 points decrease in the right side of the body and 20 points<br />decrease in the left side of the body in the group subjected to training. Based on t‑test, the<br />decrease was significant. Conclusion: The study demonstrated that majority of the participants<br />accepted interventions, which indicates that most of the people were unsatisfied with the work<br />settings and seeking improvement at the workplace. Overall, the findings show that training,<br />chair adjustment, and arrangement in workplace could decrease musculoskeletal disorders.<br /><br /> https://jehp.mui.ac.ir/article_26728_6c0924840f28f96026147e2cde8420af.pdf
