Nerve Conduction Study (NCS)

Overview

This is a noninvasive study that helps to diagnose peripheral nerve disorders and find the cause of abnormal sensations, such as numbness, tingling or pain. This study assesses the ability of nerves to conduct electrical impulses. The physician evaluates a waveform/response that is generated by a nerve stimulation.

Preparation

In preparation for the exam, the patient is positioned comfortably on an examination table. Electrodes are placed on the surface of the skin at various locations.

Exam

During the exam, mild electrical currents are sent into the body through stimulating electrodes. These signals travel through the target nerve. After these signals have passed through the nerve, they are detected by recording electrodes. This provides a precise measurement of the speed and strength of the nerve’s response to direct stimulation. The physician can use this data to diagnose nerve dysfunction.

End of Procedure

When the exam is complete, the electrodes are removed. The patient is allowed to go home. Because the exam is noninvasive, the patient will experience no bruising or soreness.

Key information that your Medical Provider should be informed of

If you have a pacemaker, that may impact the study. Please let your provider know.
