[Clinical and electrophysiological studies in carpal tunnel syndrome].

Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy, caused by compression of median nerve in the Carpal Tunnel at wrist, presenting with tingling and numbness of the thumb, index and middle fingers. Aim: To study the signs and symptoms and various Electrophysiological parameters in patients suggestive of CTS. Materials And Methods: A Total number of 50 patients suggestive of Carpal Tunnel Syndrome were examined in both the hands. A of total number of 30 healthy volunteers served as controls. Electro Physiological evaluation was done bilaterally using neuro perfect model – Medicaid system. Results And Conclusion: The clinical tests like Tinel’s sign and Phalen’s signs are having variable sensitivities and the Phalen’s sign is more sensitive sign in diagnosis of CTS. The longer the duration of the symptoms in CTS, the more the sensitive are the electrodiagnositic studies. Various parameters that are studied like distal motor latencies, distal sensory latencies are sensitive enough to bring out the diagnosis even in the asymptomatic hands. Increasing the number of parameters for study increase the certainty in the diagnosis of Carpal Tunnel Syndrome. The elecrodiagnosis study are helpful in confirm in the diagnosis and bringing out the sub-clinical cases to light.
