Abstract

Carpal tunnel syndrome is the commonest entrapment neuropathy. Typically patients presented with acroparasthesia and pain mainly at night. The study aims to find the value of wrist-palm median motor conduction velocity in the diagnosis of carpal tunnel syndrome. 171 patient suffer from classical symptoms and signs of carpal tunnel syndrome enrolled in the study and compared to 100 healthy control. All patients and controls undergo neurophysiological testing including wrist-palm median motor conduction velocity measurement. The study results show that most patients with carpal tunnel syndrome show abnormal wrist-palm median motor conduction velocity with sensitivity of 91% and specificity 80%.The study concluded thatmidpalm-wrist median motor conduction velocity is an easily performed electrophysiological technique. It don’t require additional equipment or expertise and give high sensitivity and specificity in the diagnosis of CTS.
