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 exams that measure the electrical activity of muscle tissues and nerves. Nerves ship out electrical signals to make your muscle tissues react in selected methods. As your muscle tissues react, they give off these signals, which can then be measured.

  • An EMG take a look at appears to be like at the electrical signals your muscle tissues make when they are at relaxation and when they are remaining used.
  • A nerve conduction examine measures how rapidly and how very well the body’s electrical signals journey down your nerves.

EMG exams and nerve conduction experiments can each aid come across out if you have a problem of your muscle tissues, nerves, or each. These exams can be accomplished independently, but they are usually accomplished at the exact time.

Other names: electrodiagnostic examine, EMG take a look at, electromyogram, NCS, nerve conduction velocity, NCV
