Electrophysiologic testing is designed to analyze the health of nerves and muscles. Testing includes nerve conduction testing (NCV) and electromyography (EMG).
Nerve conduction testing involves attaching surface electrodes to your skin and applying mild electrical currents to your skin. Your muscles will twitch and your skin will tingle but the test will not harm you. The speed of your nerves is calculated.
In electromyography a sterile, disposable fine needle electrode is inserted into various muscles. When the needle is inserted you will feel as if you skin is being pinched. The needle is really a very sensitive electrical microphone that transmits electrical signals from your muscle into a computer or oscilloscope for analysis.
