EMG and Neurography - an Update

Elektromyography (EMG) and electroneurography (ENG) are established diagnostic methods. They were developed decades ago. More recent developments in this field are reviewed in this article. With this background the role of EMG/ENG in certain situations is discussed, namely traumatic lesions of peripheral nerve, compression neuropathies, polyneuropathies, motor neurone disorders, myopathies, disorders of neuromuscular transmission, disorders with increased muscular activity.
