Neues aus der Elektroneurografie

Zusammenfassung

Neuere Entwicklungen der Elektroneurografie umfassen die Verfeinerung der Diagnostik bei generalisierten Neuropathien durch den Nachweis von A-Wellen im Rahmen der routinemäßigen F-Wellen-Untersuchung, methodische Verbesserungen der Diagnostik umschriebener Nervenläsionen (Karpaltunnelsyndrom, Ulnaris-kompression am Ellenbogen) und innovative Ansätze zum Nachweis temporaler Dispersion in motorischen Nerven mit normaler Nervenleitgeschwindigkeit. Diese Entwicklungen werden hier besonders unter Gesichtspunkten der Praxisrelevanz vorgestellt.

Abstract

Recent developments in electroneurography include improvements in the diagnosis of generalised neuropathies by the detection of A-waves during routine F-wave studies, methodological improvements in the diagnosis of nerve entrapment syndromes (carpal tunnel syndrome, ulnar neuropathy at the elbow), and an innovative approach to the detection of temporal dispersion in motor nerves with normal conduction velocity. These developments are reviewed, especially from a practical point of view.
