Objective: To determine frequency, etiologies, clinical and electrodiagnostic features of the Carpal tunnel syndrome (CTS)


A descriptive cross-sectional study was performed in neurology department Mayo Hospital Lahore. After taking the approval from ethical committee of King Edward Medical University Lahore, 94 patients were included study from July 2022 to December 2022. Patients diagnosed as CTS on the basis of history, clinical examination of age 18-70 years were selected. Patients with history suggestive of polyneuropathy and radiculopathy were excluded from the study. Information was collected on the pre-designed performa along with other demographic variables.


 Out of 861 patients of neuropathies due to various disorders, 94 patients were having CTS with over all prevalence was 10%.Atotal of 94 patients were evaluated with a mean age of 40.4±11.1.Among them, 79.8% were females and 20.02% were males. In electrodiagnostic settings 57.4% patients had unilateral and 42.6% had bilateral carpal tunnel syndrome (CTS). Idiopathic Carpal tunnel syndrome, and obesity were the main etiologies with prevalence of 53.1% and 26.8% respectively and 6.3% diabetic patients had isolated carpal tunnel syndrome.According to electrophysiological criteria of carpal tunnel syndrome, 21.5% cases were mild, 54.2% were moderate, and 23.4% were severe.


 Carpal tunnel syndrome is more prevalent in females than in males. Idiopathic carpal tunnel syndrome (CTS) is most frequently encountered in electrodiagnostic laboratory. It is recommended to evaluate contralateral asymptomatic side in the clinically diagnosed patients because symptomatic carpal tunnel syndrome in one hand usually comes with the asymptomatic carpal tunnel syndrome (CTS) in the contralateral hand.
