Electromyography (EMG) & Nerve Conduction Studies (NCS)

The test

• You can print the pamphlet about the Electromyography & Nerve Conduction Studies (PDF) or look at our NCS/EMG Book (PDF).
• Electromyography (EMG) is a test which records the electrical response of specific muscles.
• Nerve conduction studies (NCS) are tests which record how fast messages travel along the nerves in the arms and legs.

Preparation for an electromyogram (EMG) / nerve conduction study

• Both tests are usually done together with the NCS being done first.
• Most children are sedated for this test as it is very important for them to lie still -- see Preparation for Being Sedated.
• Sleep deprivation is not necessary for these tests.
