Electrophysiological cross section of the motor unit.
A new technique to investigate the motor unit organisation in man is described. By moving an EMG electrode through the motor unit a continuous scan or "electrophysiological cross section" is obtained. Computer processing methods are used for analysis and display. Examples are shown from healthy subjects and from patients with neuromuscular diseases.
