An electromyograph (EMG) graphically records the electrical activity of muscles. Normal muscle is electrically silent when at rest, but when it is active, as during contraction or stimulation, an electrical current is generated. The successive action potentials are measured through surface electrodes that are connected to a signal amplifier and recording device.
