Nerve conduction

Nerve Conduction

Nerve conduction is a medical test that measures the speed and strength of signals traveling between two points in the nervous system. This test is often used to diagnose nerve damage or dysfunction.

Overview

Nerve conduction studies (NCS) are medical diagnostic tests that measure the speed and strength of electrical activity in a nerve. The test can provide information about nerve function and integrity, and can help diagnose various neurological conditions.

Procedure

During a nerve conduction study, electrodes are placed on the skin over the nerve to be studied. A small shock, similar to a static electricity shock, is delivered to the nerve, and the resulting electrical activity is recorded by the other electrodes. The speed (conduction velocity) and size (amplitude) of the response are measured.

Uses

Nerve conduction studies are used to diagnose a number of conditions, including peripheral neuropathy, carpal tunnel syndrome, and Guillain-Barré syndrome. They can also be used to evaluate the severity of nerve damage.

Risks

Nerve conduction studies are generally safe procedures. However, they can cause some discomfort, and there is a small risk of skin irritation or bruising at the electrode sites.
