Relationship between using tables, chairs, and computers and improper postures when doing VDT work in work from home

Area of Science:

• Ergonomics
• Occupational Health
• Biomechanics

Background:

• The rise of remote work necessitates understanding ergonomic risks associated with home office setups.
• Improper workstation configurations are linked to an increased incidence of musculoskeletal disorders (MSDs).

Purpose of the Study:

• To investigate the impact of various furniture and computer combinations on body posture during simulated work-from-home tasks.
• To identify specific setups that elevate the risk of musculoskeletal issues.

Main Methods:

• Twenty-one healthy participants performed a 30-minute visual display terminal task under seven different furniture (tables, chairs, cushions) and computer (desktop, laptop, tablet) conditions.
• Three-dimensional body posture was quantitatively assessed using a magnetic tracking system.

Main Results:

• Using a low table, floor chair, and laptop resulted in postures similar to a dining table, chair, and desktop setup.
• Severe neck flexion, a risk factor for neck strain, was observed when using sofas or floor cushions with laptops or tablets.
• Excessive low back flexion, indicative of lumbar stress, occurred with floor cushions and laptops.

Conclusions:

• Working on sofas or floor cushions without backrest support while using computers poses significant risks to neck and low back health.
• Ergonomic assessments of home workstations are crucial to mitigate the risk of developing work-related musculoskeletal disorders.
