Nerve Conduction/EMG

Electromyography (EMG) is a test of a muscle’s electrical activity. It is used to test how a muscle responds to signals from the nerves responsible for muscle movement, called motor nerves. An EMG may also include a test of how fast the motor nerve conducts impulses. This is called a nerve conduction study (NCS) or nerve conduction velocity (NCV) test.
