Nerve Conduction Study (NCS) / Electromyography (EMG) is a diagnostic test that assesses the health of nerves and muscles.
There are two parts to the test:
1. Nerve Conduction Study
This measures the flow of electrical impulses along a nerve to check for nerve damage. It is often done before the Needle Electrode Examination, a complementary test to check how well muscles are functioning.
2. Needle Electrode Examination
This checks how well muscles are functioning.
The test may take up to anywhere from 30 minutes to 1 hour 30 minutes depending upon the complexity of the case.
How should I prepare for the tests?
Nerve Conduction Study
How is the test performed?
The test is done by a neuro electrophysiologist and takes around 30 minutes to an hour.
Needle Electrode Examination
The test is done by an EMG-trained neurologist and takes around 30 minutes.
Frequently Asked Questions
Are these tests safe?
The tests are generally safe although some patients may experience discomfort. The electrophysiologist and doctor will be with you throughout the process. If you feel unwell, speak to the neuro electrophysiologist or doctor.
It is normal for your muscles to feel sore after the test. It should get better after a few days. If you feel severe pain or swelling at the site, call us.
