Carpal tunnel syndrome severity and work: a case-control study.

Area of Science:

• Occupational Health
• Epidemiology
• Orthopedics

Background:

• Carpal tunnel syndrome (CTS) is a prevalent condition with significant societal impact.
• Factors contributing to CTS severity, particularly occupational influences, require further investigation.

Purpose of the Study:

• To examine the association between carpal tunnel syndrome (CTS) severity and occupational biomechanical factors.
• To evaluate the role of personal anthropometric risk factors in CTS development and severity.

Main Methods:

• A case-control study design was employed, comparing 183 CTS cases with 445 controls.
• CTS severity was classified using validated clinical and electrophysiological scales.
• Logistic regression models, adjusted for covariates, assessed the relationship between blue-collar status, anthropometric indices, and CTS.

Main Results:

• Blue-collar workers demonstrated a significantly higher risk of developing CTS (OR 2.4).
• Specific occupations like vine/olive growers and food processing workers exhibited elevated CTS risk.
• Blue-collar status and anthropometric factors (wrist-palm ratio, waist-stature ratio) were independently associated with moderate to severe CTS.

Conclusions:

• Blue-collar occupations are linked to an increased risk of carpal tunnel syndrome, independent of anthropometric measures.
• Interventions aimed at reducing upper limb biomechanical overload and managing overweight are recommended for CTS prevention.
