Carpal tunnel syndrome and work

Area of Science:

• Orthopedics
• Occupational Health
• Epidemiology

Background:

• Carpal tunnel syndrome (CTS) is a common condition affecting the median nerve at the wrist.
• The relationship between occupational demands and CTS incidence and severity is not fully understood.

Purpose of the Study:

• To investigate the incidence, age at presentation, disability, and surgical outcomes of carpal tunnel syndrome in working-age women.
• To determine if occupational factors (repetitive vs. non-repetitive work) influence CTS presentation and severity.

Main Methods:

• Retrospective analysis of 327 working-age women diagnosed with carpal tunnel syndrome.
• Assessment of symptom severity and disability using the Michigan Hand Questionnaire and SF-12.
• Comparison of incidence rates and surgical referral rates across employment groups (working, repetitive work, non-working).

Main Results:

• Higher population incidence of CTS in women in non-repetitive occupations (220/100,000/year) compared to repetitive (122/100,000/year) or non-working (129/100,000/year) groups.
• Working women reported less severe symptoms and disability than non-working women.
• A higher percentage of working women were offered surgery (82%) compared to those in repetitive (67%) or non-working (58%) groups.

Conclusions:

• Occupational work, whether repetitive or non-repetitive, does not appear to cause, aggravate, or accelerate carpal tunnel syndrome.
• Working women may seek surgical intervention more readily due to challenges in symptom accommodation compared to non-working individuals.
