What happens during a nerve conduction study (NCS) procedure?

ANSWER

The technician puts electrode patches on your skin over the nerve that may be causing your symptoms. A stimulating electrode sends a mild electrical impulse to the nerve. The other electrodes record the nerve’s response.

If the signal travels at a slower rate than it should in a healthy nerve, it means the nerve is probably damaged. You may need more tests to learn whether the nerve can become healthy again.
