Carpal tunnel syndrome (CTS) is the most commonly-encountered entrapment neuropathy with an incidence of 139 per 100,000 person-years for men and 506 per 100,000 person-years for women. The symptoms and signs are caused by compression of the median nerve along the carpal tunnel, which is formed on the distal, medial, and lateral sides by the carpal bones and on the volar surface by the deep transverse carpal ligaments. The classic symptoms of CTS are numbness and paraesthesia in the first three fingers of the hand, which is commonly exacerbated at night. The diagnostic signs include sensory loss along the lateral aspect of the hand, motor weakness and wasting of abductor pollicis brevis (APB) muscle, and eliciting Tinel’s and Phalen’s sign at the wrist. The nerve conduction study (NCS) study is a definite diagnostic test for CTS with high degree of sensitivity and specificity. This test demonstrates a distal lesion of the median nerve and excludes other peripheral conditions resulting in similar symptoms. Ultrasonography is also an upcoming tool in the diagnosis of carpal tunnel syndrome with equal sensitivity as electrophysiological studies. The present study is being done to evaluate the clinical profile, electrophysiological severity and radiological profile in patients with symptoms and signs suggestive of carpal tunnel syndrome. Duration of symptoms with carpal tunnel syndrome correlated very well with the severity in this study. Electrophysiological studies identified subclinical carpal tunnel syndrome in asymptomatic hands in three fourths of patients. Electrophysiological studies helped to assess the severity of carpal tunnel syndrome which could influence the management.
