What to Expect

Prior to Test

Before your procedure:

Description of Test

Your skin will be cleaned. Electrodes will be taped to the skin along the nerves that are being studied. A small stimulus will be used to apply an electric current that causes the nerves to activate. The electrodes will measure the current that travels down the nerve pathway. The current will be slower and weaker if your nerve is damaged. Your doctor will use the stimulus at different places to determine the specific site of the damage.
Nerve conduction studies are often done along with electromyography (EMG).

After Test

You will be able to resume your daily activities after the test is complete.

How Long Will It Take?

About 30-90 minutes

Will It Hurt?

You will feel mild discomfort from the shocks. It should not be very painful.

Results

Your doctor will study the information from the test. A report should be ready within a few days.
