Abstract

Background: Carpal tunnel syndrome (CTS) represents 90% of entrapment neuropathies. Severity may be greater in older patients. Aim: To describe the electrophysiological findings in adult patients with CTS and determine if severity is related to age. Material and Methods: Descriptive and retrospective study of electrophysiological findings in patients over 18 years of age with clinical suspicion of CTS, studied between January 2011 and December 2015. Neurophysiological severity was classified in 3 grades, comparing them by age, gender and laterality. Results: Of 1156 patients subjected to electrophysiological studies due to a clinical suspicion of CTS, 690 (60%) had electrophysiological features of the disease. In 274 patients (24%) the compromise was mild, in 162 (14%) it was moderate and in 254 (22%) it was severe. There was a positive association between age and CTS severity (p < 0.01). Severity was significantly greater in males than females (p < 0.01). Bilateral CTS was present in 471 patients (68%), which was associated with increased age and severity (p < 0.01). Conclusions: Electrophysiological severity in CTS increases with age. Other factors associated with higher severity are male gender and bilateral disease.

Bibliographical note

Funding Information:
El haber utilizado una escala empírica para la clasificación del compromiso de STC agrupando los 6 estadios de Bland en 3 grandes grupos (leve, moderado y grave), permite acercarse más a la práctica clínica habitual y realizar comparaciones con estudios internacionales que han utilizado métodos similares6. Se debe recordar que esta escala permite reconocer el compromiso de la neuropatía del nervio mediano en la muñeca, por lo cual es necesario complementar siempre con la clínica del paciente35.
