[Computer work and De Quervain's tenosynovitis: an evidence based approach]

Area of Science:

• Occupational health
• Musculoskeletal disorders
• Epidemiology

Context:

• The relationship between occupational computer use and De Quervain's Tenosynovitis remains debated.
• Existing research often lacks a multidisciplinary approach, overlooking crucial data.
• Disorders of the upper limbs related to video display unit (VDU) use require careful differentiation, particularly those linked to overuse.

Purpose:

• To systematically review the literature on the association between personal computer use and De Quervain's Tenosynovitis.
• To evaluate the evidence for a causal link, considering experimental and clinical data.
• To identify gaps in current research regarding digital device usage and this condition.

Summary:

• A systematic review found no conclusive evidence linking general personal computer or keyboard use to De Quervain's Tenosynovitis.
• Limited evidence suggests a potential correlation between extended mouse usage and the condition.
• Data on the specific impact of laptops and smartphones on De Quervain's Tenosynovitis is currently unavailable.

Impact:

• Highlights the lack of robust scientific evidence supporting a direct link between typical computer use and De Quervain's Tenosynovitis.
• Underscores the need for further research into the specific ergonomic factors and usage patterns associated with digital devices.
• Informs occupational health guidelines and clinical assessments by clarifying the current state of evidence.
