Abstract:
Background: Musculoskeletal disorders are commonly reported among computer users. This
study explored whether these disorders can be reduced by the provision of ergonomics education.
Methods: A cluster randomised controlled trial was conducted in which 3 units were
randomised for intervention and received training, and 3 units were given a leaflet. The effect of
intervention on workstation habits, musculoskeletal disorders, days and episodes of sick leave, and
psychological well-being were assessed.
Results: A significant improvement in workstation habits was found, and the differences
remained significant at the follow-up time point for keyboard, mouse, chair, and desk use. The
largest reduction in the percentage of musculoskeletal disorders was in the neck region (-42.2%,
95% CI -60.0 to -24.4). After adjusting for baseline values, significant differences were found at the
follow-up time point in the neck, right shoulder, right and left upper limbs, lower back, and right and
left lower limbs. No significant differences were found for the days and episodes of sick leave or the
psychological well-being among workers after the intervention.
Conclusion: Consistent reductions were observed for all musculoskeletal disorders at the
follow-up time point, although the difference was not statistically significant for the upper back. The
improvements in the musculoskeletal disorders did not translate into fewer days lost from work or
improved psychological well-being.
