Summary
The free-address office system improves workspace and communication but may lead to poor posture and pain for visual display terminal (VDT) workers. Further research is needed to understand health impacts.
Area of Science:
- Occupational Health
- Ergonomics
- Office Design
Background:
- The free-address system, a novel office layout, allows workers to choose their workspace.
- Its impact on visual display terminal (VDT) workers' posture and workload is not well understood.
Purpose of the Study:
- To investigate the effects of the free-address system on VDT workers' posture and workload.
- To compare the free-address system with the traditional fixed-address layout.
Main Methods:
- A questionnaire survey was conducted among 203 male system engineers (aged 20-59) using notebook computers.
- Participants were divided into two groups: 150 using the free-address layout and 53 using the fixed-address layout.
Main Results:
- The free-address layout enhanced individual workspace and worker satisfaction with communication and support.
- However, workers in the free-address system adopted unsuitable postures, often without adjusting chair height.
- This layout may increase the risk of neck/shoulder and low back stiffness or pain.
Conclusions:
- While offering workspace benefits, the free-address system presents potential health risks for VDT workers.
- Further investigation into the long-term effects on VDT worker health is crucial.
