NERVE CONDUCTION STUDIES AND ELECTROMYOGRAPHY


NCS PROCEDURE EXPLAINED

During the test, your nerve is stimulated, usually with electrode patches attached to your skin. Two electrodes are placed on the skin over your nerve. One electrode stimulates your nerve with a very mild electrical impulse. The other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested.The speed is then calculated by measuring the distance between electrodes and the time it takes for electrical impulses to travel between electrodes. The voltage of the electrical pulses used during an NCV is considered very low.

WHAT IS AN EMG?

A related test that may be done is an electromyography (EMG). This measures the electrical activity in your muscles. It is often done at the same time as an NCS. Both tests help find the presence, location, and extent of diseases that damage the nerves and muscles.

The tests are typically carried out for conditions like carpal tunnel syndrome, ulnar neuropathy, peripheral neuropathies and radiculopathies.

PREPARATION

There is no specific preparation for the procedure. Dress in clothes that allow access to the area to be tested. Please do not use lotions or oils on your skin on the day of the procedure.
