Summary
Office workers using various information and communication technologies (ICT) showed different postures. Varying ICT tasks throughout the day may reduce musculoskeletal complaints by increasing postural variation.
Area of Science:
- Ergonomics
- Occupational Health
- Human-Computer Interaction
Background:
- Office workers utilize diverse information and communication technologies (ICT), leading to varied postures.
- Postural variation is believed to prevent musculoskeletal issues, but its relationship with ICT use is understudied.
Purpose of the Study:
- To compare postures and postural variation across different ICT types among office workers.
- To investigate the impact of ICT on postural diversity during the workday.
Main Methods:
- Measured upper arm, head, and trunk postures of 24 office workers using the Physiometer.
- Quantified postural variation using APDF(90-10) and EVA(sd) indices over a full workday.
- Compared postures and variations across paper-based, electronics-based, and combined ICT tasks, as well as non-ICT tasks.
Main Results:
- Different ICTs resulted in distinct postural means and variations.
- Paper-based tasks showed more non-neutral and variable postures.
- Electronics-based tasks exhibited more neutral postures with less variability.
- Combined paper and electronics tasks had the least neutral and least variable postures.
- Non-ICT tasks displayed the highest postural variability.
Conclusions:
- ICT significantly influences office worker postures and postural variation.
- Integrating diverse ICT tasks can enhance overall postural exposure variation.
- Increased postural variation through varied ICT use may reduce musculoskeletal risk.
