Summary
Intensive computer mouse use significantly increases forearm pain risk. While clinical disorders are rare, keyboard use and job pressure also contribute to forearm pain, particularly in women.
Area of Science:
- Occupational Health
- Epidemiology
- Musculoskeletal Disorders
Background:
- Forearm pain is a common complaint among computer workers.
- Understanding risk factors is crucial for prevention and management.
Purpose of the Study:
- Determine forearm pain prevalence and incidence in computer workers.
- Evaluate risk factors associated with forearm pain.
Main Methods:
- A cohort of 6943 computer workers completed questionnaires at baseline and one-year follow-up.
- Clinical examinations were offered to participants with relevant symptoms.
- Forearm pain cases were defined by self-reported pain and clinical tenderness.
Main Results:
- The prevalence of moderate to severe forearm pain was 4.3%.
- Mouse use >30 hours/week and keyboard use >15 hours/week increased risk.
- High job demands, time pressure, and female sex were significant risk factors.
Conclusions:
- Intensive mouse and keyboard use are primary risk factors for computer-related forearm pain.
- Clinical forearm disorders were infrequent, indicating low severe occupational hazard.
- Ergonomic factors at the workplace did not predict future forearm pain.
