Assessment the effectiveness of ergonomics training on the improvement of work methods in hospital office staff

working with computer in long duration, static condition, and poor posture may lead to musculoskeletal disorders. The aim of this study was to assess an educational and ergonomic intervention on improving work procedure among computer users in office work in 2016. This descriptive-analytic study was carried out on 28 employees of administrative staff of Damghan ward. In order to determine the level of ergonomic risk, the physical status of patients before and 6 months after intervention was evaluated using ROSA method. The ergonomic principles were also used to increase the staff's awareness. Finally, one-way analysis of variance and independent t-test were used to analyze the statistical data. Prior to the implementation of the educational intervention program, the most important risk factors were in the neck (P=0.009), elbows (P=0.019) and shoulders (P=0.031), respectively, respectively. From the intervention, this level of risk was reduced in the organs, which was a significant change. There were also age (P=0.028), gender (P=0.015), BMI (P=0.040), education level (P=0.047) and job experience (P=0.025) Had a significant effect on the final score of ROSA. The results indicate the prevalence of musculoskeletal disorders and ergonomic risk level by ROSA method which requires ergonomic intervention in the design of the environment, tools and equipment along with educational intervention.
