The Prevalence of Musculoskeletal Disorders and Awareness about Principles of Computer Ergonomics in Computer Users

Due to the prevalence of musculoskeletal disorders among computer users, this study was aimed at investigating the prevalence of musculoskeletal disorders and awareness about the principles of ergonomics among computer users.

In this descriptive-analytical and cross-sectional study, data were collected using demographic questionnaires, Nordic questionnaire, and self-constructed questionnaires. Chi-square, independent t-test, ANOVA, and correlation analyses were used to analyze the data statistically.

The most prevalent signs of musculoskeletal disorders were in the waist, neck, shoulder, back, wrists, and knees. The level of awareness about the appropriate height of monitor and the proper distance between eyes of the operator and monitor was low. Although musculoskeletal disorders were lower in people with high levels of awareness about computer ergonomics, no significant relationship was found between the frequency of musculoskeletal disorders and awareness about computer ergonomics.
