Aim: To determine the predictive factors of the neuropathic pain in patients with carpal tunnel syndrome (CTS), and the impact of such neuropathic pain on patient's activity.
Methods: Douleur Neuropathique 4 questionnaire, Short Form-Brief Pain Inventory test and Boston Carpal Tunnel Syndrome Questionnaire were completed and results were stratified according neuropathic pain and work activity of the patients.
Results: 69 of 90 patients with CTS had neuropathic pain (76.7%). Increasing by one the scores of numbness/tingling, pain intensity and neurologic affectation of the electromyogram meant increasing 3.3-, 2.7- and 4.4-times the risk of neuropathic pain, respectively.
Conclusion: These results will be useful for a better neuropathic pain evaluation in patients with CTS, allowing the appropriate treatment.
Keywords: DN4 questionnaire; carpal tunnel syndrome; neuropathic pain.
