VDT ergonomics: upper extremity assessment requires a holistic approach

Area of Science:

• Occupational Health
• Ergonomics
• Musculoskeletal Disorders

Background:

• Repetitive strain injuries (RSI) of the hand and upper extremity are increasingly associated with video display terminal (VDT) use.
• The proliferation of computer use in both professional and domestic settings has led to a rise in RSI incidence.

Purpose of the Study:

• To present a holistic approach for managing and preventing upper extremity RSI in VDT users.
• To emphasize the importance of workstation ergonomics, starting with proper seated posture.

Main Methods:

• Focusing on the seated position as the foundation for ergonomic adjustments.
• Incorporating instruction on appropriate seating, posture, keyboard technique, work pacing, and specific exercises.
• Developing a checklist for VDT ergonomic analysis.

Main Results:

• Simple adjustments to the seated position can significantly improve shoulder, arm, and hand positioning.
• A comprehensive approach including posture, technique, and exercises addresses multiple facets of RSI prevention.
• A standardized checklist aids in evaluating VDT workstation ergonomics.

Conclusions:

• A holistic ergonomic strategy, beginning with correct posture and workstation setup, is crucial for addressing upper extremity RSI.
• Educating VDT users on proper technique and providing targeted exercises are key components of RSI management.
• The developed checklist offers a practical tool for ergonomic analysis and intervention.
