Nerve Conduction Study (NCS) / Electromyography (EMG)

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. It will cause 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. Stimulus will be used at different places to find the site of the damage.

Nerve conduction studies are often done along with electromyography (EMG).

Do not use any creams, moisturizers, or powders on your skin. Wear loose fitting clothing.

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

About 40 minutes to 1 hour.

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

Your provider will study the details from the test. A report should be ready within a few days. Your provider will review your results with you at your next follow up appointment.
