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.
