What is EMG Testing?

An EMG, or an electromyogram, measures electrical activity activity of muscles both at rest and in contraction. An EMG can be done to locate the source of muscle weakness, paralysis, or twitching, which could be inside a muscle, in the nerves supplying a muscle, in the spinal cord, or inside an area of the brain. It tests for things like herniated discs or amyotrophic lateral sclerosis.

What is a Nerve Conduction Study?

A Nerve Conduction Study, or NCS, measures how well nerves are able to send electrical signals. Both tests can be done to learn what is causing nerve and muscle issues or pain. An NCS is performed in order to locate damage to the peripheral nervous system. This test can discover nerve damage such as carpal tunnel syndrome or Guillain-Barré syndrome.
