Is Carpal Tunnel Syndrome Related to Computer Exposure at Work? A Review and Meta-Analysis


Objective: A meta-analysis on epidemiological studies was undertaken to assess association between carpal tunnel syndrome (CTS) and computer work.

Methods: Four databases (PubMed, Embase, Web of Science, and Base de Donnees de Sante Publique) were searched with cross-references from published reviews. We included recent studies, original epidemiological studies for which the association was assessed with blind reviewing with control group. Relevant associations were extracted, and a metarisk was calculated using the generic variance approach (meta–odds ratio [meta-OR]).

Results: Six studies met the criteria for inclusion. Results are contradictory because of heterogeneous work exposure. The meta-OR for computer use was 1.67 (95% confidence interval [CI], 0.79 to 3.55). The meta-OR for keyboarding was 1.11 (95% CI, 0.62 to 1.98) and for mouse 1.94 (95% CI, 0.90 to 4.21).

Conclusion: It was not possible to show an association between computer use and CTS, although some particular work circumstances may be associated with CTS.
