The study of the anatomy and physiology of the motor unit has important implications in
the diagnosis and follow-up of neuromuscular pathologies. Muscle action potentials allow
the use of electrophysiological techniques based on electromyography (EMG) to make
inferences about muscle structure, state and behaviour. Scanning EMG is one such
technique that can record the temporal and spatial distribution of electrical activity of a
single motor unit, allowing for deep insight into the structure and function of motor units.
In this chapter, we describe the scanning EMG technique in detail, both from a technical and
clinical point of view. A brief review of the motor unit anatomy and physiology is provided
in Section 2. The technique, the apparatus setup, the recording procedure and the signal
processing required are described in Section 3. Key results of studies using scanning EMG
are reviewed in Section 4, including findings related to motor unit organisation in normal
muscle and how changes due to pathology are reflected using this electrophysiological
technique. Finally, Section 5 provides some hints regarding the use of scanning EMG in
research. [--]
