Electromyography (EMG) and Nerve Conduction Studies: MedlinePlus Lab Test Information

What are electromyography (EMG) and nerve conduction experiments?

Electromyography (EMG) and nerve conduction experiments are assessments that measure the electrical action of muscles and nerves. Nerves send out electrical alerts to make your muscles react in certain methods. As your muscles react, they give off these alerts, which can then be calculated.

• An EMG check appears at the electrical alerts your muscles make when they are at rest and when they are remaining used.
• A nerve conduction analyze steps how quickly and how perfectly the body’s electrical alerts journey down your nerves.

EMG assessments and nerve conduction experiments can both aid obtain out if you have a disorder of your muscles, nerves, or both. These assessments can be done separately, but they are commonly done at the similar time.

Other names: electrodiagnostic analyze, EMG check, electromyogram, NCS, nerve conduction velocity, NCV
