What is NCV Test

Nerve Conduction Velocity Study (NCV) is a test commonly done to evaluate the function, especially the ability of electrical conduction of the motor and sensory nerves of the human body. Nerve conduction velocity (NCV) is a common measurement made during this test. Nerve conduction velocity (NCV) is a test to see how fast electrical signals move through a nerve.

In cases of injury to the arm or the legs these nerves can get damaged and their capacity to carry electrical signals get reduced. In patients who consume a lot of alcohol or diabetic patients these nerves age much faster and their functioning becomes less effective which causes numbness or tingling sensations in the fingers of the hands or the legs.

During the test, the nerve is stimulated, usually with surface electrode patches attached to the skin. Two electrodes are placed on the skin over the nerve. One electrode stimulates the nerve with a very mild electrical impulse and the other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested.

The nerve conduction velocity (speed) is then calculated by measuring the distance between electrodes and the time it takes for electrical impulses to travel between electrodes.

Why NCV is Done

Conditions that may be evaluated with NCV include the following:

best centre for ncv test, best doctor for nerve conduction velocity test, cost of ncv test in gurgaon, where can i get ncv test in gurgaon Guillain-Barré syndrome - A condition in which the body's immune system attacks part of the peripheral nervous system. The first symptoms may include weakness or tingling sensations in the legs.

This results in pain and numbness in the fingers.

One characteristic is weakness of the foot and lower leg muscles.

Test Preparation

You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is not clear.

Generally, no fasting or sedation is required prior to the procedure. Normal body temperature must be maintained before and during the procedure, as low body temperature slows nerve conduction. Notify your doctor of all medications (prescribed and over-the-counter) and herbal supplements that you are taking. Also tell your doctor if you have a cardiac defibrillator or pacemaker, as precautions may need to be taken. Stop using lotions or oils on your skin for a few days before your procedure.

During the test when the electrical impulse is given to the electrode you may feel like a mild electric tingling. Depending on how strong the stimulus is, you will feel it to varying degrees, and it may be slightly uncomfortable. You should feel no pain once the test is finished.

The test is normally done by a technician and the reports are analyzed by a neurologist. Most of the diagnostic centres normally do not have the facility of NCV testing because of the unavailability of the Neurologist. It is best to call up a diagnostic centre to find out the availability of the test and the charges.
