ANALYSIS OF ELECTRONEUROGRAPHY INDICATORS IN PERIPHERAL NERVE INJURIES OF THE UPPER LIMB

Authors:

Abstract:

This research is aimed at determining the diagnostic value of electrophysiological examination, compared with ultrasound examination and provocative compression tests, to confirm and establish the degree of severity of peripheral nerve damage, as well as prognosis for further treatment tactics on the example of compression of the median nerve in the carpal tunnel. 130 patients were examined, in whom signs of median nerve damage were detected. All patients underwent provocative tests (Phalen's, Tinel's, Durkan's). During electrophysiological examination, the following indicators were evaluated: amplitude, speed, distal latency of motor and sensory responses. The cross-sectional area of the median nerve at the entrance to the canal during sonography correlates well with the results of electrodiagnosis. Indicators electroneuromyography clearly and reliably determine moderate and severe degree of carpal tunnel syndrome. The problem of diagnosis is that some patients with clinical symptoms of carpal tunnel syndrome have indicators that are not statistically different from indicators in patients of the control group.
