Background: Several studies report a high prevalence of low back pain (LBP) among video-terminal (VDT) workers. Targeted ergonomic interventions can help reduce the burden.
Objectives: We investigated the long-term efficacy of an ergonomic postural intervention to address LBP among VDT workers.
Study design: Non-randomized, crossover trial.
Population and setting: Four hundred employees working in the administrative offices of the two main buildings of the town hall ofForlì who used VDTs for at least 20 hours a week; we randomly selected 100 participants from each building.
Intervention: Ergonomic adjustment of the VDT workstation design.
Outcome measures: Changes in prevalence of LBP and work-related posture.
Results: The ergonomic adjustment of the workstation improved work-related posture and reduced LBP in VDT operators who benefited from the intervention.
Conclusions: A personalized ergonomic prevention intervention can improve work-related posture and LBP for VDT workers.
