Other names: electrodiagnostic study, EMG test, electromyogram, NCS, nerve conduction velocity, NCV These tests can be done separately, but they are usually done at the same time. As your muscles react, they give off these signals, which can then be measured.Īn EMG test looks at the electrical signals your muscles make when they are at rest and when they are being used.Ī nerve conduction study measures how fast and how well the body's electrical signals travel down your nerves.ĮMG tests and nerve conduction studies can both help find out if you have a disorder of your muscles, nerves, or both. Nerves send out electrical signals to make your muscles react in certain ways. What are electromyography (EMG) and nerve conduction studies?Įlectromyography (EMG) and nerve conduction studies are tests that measure the electrical activity of muscles and nerves.
