This Research study aims to investigate the long term effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) of Video Display Terminal (VDT) workers

Official Title: | Effectiveness of an Ergonomic Intervention on Work-Related Posture and Low Back Pain in Video Display Terminal Operators: a 3 Year Cross-Over Trial |
Enrollment: | 200 |
Study Start Date: | January 2005 |
Study Completion Date: | December 2007 |
Primary Completion Date: | June 2005 (Final data collection date for primary outcome measure) |
Arms | Assigned Interventions |
---|---|
1: Experimental
The first Arm received the intervention between baseline and the first follow-up, whereas the second Arm was the Control group
|
Other: Ergonomic Intervention
The intervention used in this investigation was an ergonomic adjustment of the VDT workstation design
|
2: Experimental
The second Arm received the intervention between the third and the fourth follow-up, whereas the first Arm was the Control group
|
Other: Ergonomic Intervention
The intervention used in this investigation was an ergonomic adjustment of the VDT workstation design
|
A non-randomized, crossover trial design was used with follow-up repeated 6, 12, and 30 months from baseline in the first intervention period and then beginning at 6 months following the crossover.
The administrative offices in the two main buildings of the town hall of Forlì, Italy.
The study population was composed of 400 employees, who used VDTs for at least 20 hours a week, of whom we randomly selected 100 participants from each building. Of the 200 initial participants, 153 completed the study; the dropouts were due to illness/injury or maternity. Participants were assigned to intervention or control during the first period and then crossed over after a 30-month washout. The intervention used in this investigation was an ergonomic adjustment of the VDT workstation design. Our study showed that the workstation ergonomic adjustment improved work-related posture and in reducing LBP in VDT operators among subjects who received the intervention both in the first period and in the crossover, and maintained these positive effects for at least 30 months.
