Occupational and Biopsychosocial Risk Factors for Carpal Tunnel Syndrome

Objective: To investigate a biopsychosocial model of risk for carpal tunnel syndrome (CTS). In addition, a host of exploratory psychosocial variables was investigated as potential risk factors for CTS.
Methods: A case–control design was used comparing 87 CTS and 74 sex-matched general orthopedic patients from an outpatient orthopedic clinic. All participants underwent the same diagnostic protocol (ie, physical evaluation and electrodiagnostic testing) and completed a self-report questionnaire assessing a wide range of potential occupational, personological, and psychosocial risk factors.
Results: Multiple logistic regression analyses revealed that occupational repetition, not engaging in vigorous exercise, physical activities with wrist strain, poorer physical health, and lower job satisfaction were significantly related to the presence of CTS. Obesity was borderline significantly related to the presence of CTS.
Conclusions: The biopsychosocial model provides a useful heuristic for conceptualizing CTS risk among injured workers.
