Clinical Electrophysiology study in Carpal Tunnel study

Carpal Tunnel syndrome is a commondesosder and median nerve is more involved than other nerves. The main aim of this study is to clarrifing correlation between clinical symptoms and signs with electsro physiological findings in one hand and detectetion of the most sensitive Electlophysiologic index in the other hand. 40 patients adimitted in 22 Bahman & Arya hospital during Year 2002 was enrolled in this study. our specific test was performed for them. this was a prospective study. Main cause of CTS was Diabetes Melitus. Although Most pationts discomfort unilaterally electcophsilogical a bnormalities Was present in both sides. The most sensitive test was Distal Sensory median latency and flatency has the same Value. Electromyography was abnormal in only 7% of patients. Detection of underdyiny disease before surgery is manadatory. It seems that F wave has the same value as distal median sensory nerve in in carpal tunnel syndrome.
