Abstract
Electromyography (EMG) is the recording of the electrical activity of the muscle. The electrical activity is muscle action potentials from depolarised muscle fibres. Muscle fibres that belong to one motor unit are scattered throughout the muscle in such a way that fibres belonging to the same motor unit are rarely next to each other. When the motor unit is activated, all muscle fibres belonging to it are depolarised nearly synchronously and these muscle fibre action potentials summate to a motor unit action potential (MUAP).
