EMG / NCS Procedures

What is an Electrodiagnostic test (EMG/NCS)?

This test is composed of 2 parts.

1. The first part is the nerve conduction study (NCS). This will evaluate how well the nerves are sending signals to each other.
2. The second part is the electromyography (EMG). This will evaluate the muscles which the nerves supply

What can I expect during this test?

The NCS will feel like an electrical impulse. The EMG portion uses a small needle to evaluate the muscles.

Do I need to stop my medications?
