Nerve conduction velocity (NCV) testing is a diagnostic test used to measure the speed and strength of electrical signals that travel through your nerves. This test is often used to diagnose nerve damage or conditions such as carpal tunnel syndrome, peripheral neuropathy, or sciatica. In this blog, we will explore what nerve conduction velocity testing is and how it works.
What is Nerve Conduction Velocity Testing?
Nerve conduction velocity testing is a type of electrodiagnostic test that measures how quickly electrical signals travel through your nerves. During the test, small electrodes are placed on your skin at various points along the nerve pathway being tested.
The electrodes are used to deliver a small electrical impulse that stimulates the nerve. The impulse then travels along the nerve pathway, and the response is recorded by another electrode. The time it takes for the impulse to travel between the electrodes is measured, and this measurement is used to calculate the nerve conduction velocity.
How Does Nerve Conduction Velocity Testing Work?
Nerve conduction velocity testing is a non-invasive and painless procedure that typically takes less than an hour to complete. Before the test, you may be asked to avoid caffeine and other stimulants that can affect your nerves’ responses. You may also be asked to avoid certain medications that can interfere with the test results.
During the test, you will lie down on a table, and the technician will place electrodes on your skin at various points along the nerve pathway being tested. The technician will then deliver a small electrical impulse to the nerve, and the response will be recorded by another electrode. The test may be repeated several times to ensure accuracy.
After the test, your results will be analyzed by a specialist, and the information will be used to diagnose any nerve damage or conditions you may have. Your doctor will then use this information to develop a treatment plan tailored to your specific needs.
