Clinical neurophysiology is a branch of medicine concerned with the measurement of the electrical activity of the central nervous system, peripheral nerves and muscles.
The measurements of electrical activity are usually sensitive but, as far as the aetiology of the lesion is concerned, non-specific.
The investigations are labour-intensive, and they are consultations by nature.
Some of the investigations are uncomfortable for the patient. Neurophysiological investigations are therefore not suitable for screening purposes.
