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

What are electromyography (EMG) and nerve conduction scientific tests?

Electromyography (EMG) and nerve conduction scientific tests are checks that measure the electrical action of muscle tissues and nerves. Nerves mail out electrical signals to make your muscle tissues respond in specified ways. As your muscle tissues respond, they give off these signals, which can then be calculated.

  • An EMG exam seems to be at the electrical signals your muscle tissues make when they are at rest and when they are getting used.
  • A nerve conduction analyze steps how fast and how properly the body’s electrical signals travel down your nerves.

EMG checks and nerve conduction scientific tests can equally enable find out if you have a ailment of your muscle tissues, nerves, or equally. These checks can be finished separately, but they are normally finished at the identical time.

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