An electromyogram (EMG) is a recording of the electrical activity of muscles. The EMG signal reflects the electrical activity of skeletal muscles and contains information about the structure and function of muscles which make different parts of the body move. The EMG signal conveys information about the controller function of the central and peripheral nervous systems on the muscles. As such, the EMG signal provides a highly useful characterization of the neuromuscular system since many pathological processes, whether arising in the nervous system or the muscle, are manifested by alterations in the signal properties[1]. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
