Nerve Conduction Velocity (NCV)
A Nerve Conduction Velocity (NCV) is used to assess nerve damage and dysfunction. The procedure measures the speed at which an electrical impulse travels along a nerve. NCV can help diagnose a variety of muscular and neuromuscular conditions such as differentiating between an injury to the nerve fiber and an injury to the myelin sheath, the protective covering surrounding the nerve. It can also help your doctor tell the difference between a nerve disorder and a condition where a nerve injury has affected the muscles.
Sometimes, NCV tests are done in conjunction with electromyograms (EMG). It helps doctors to help diagnose neurological or muscular diseases.
Uses of Nerve Condition Velocity
A nerve condition velocity can be used to diagnose the following conditions;
- Herniated Disk Disease
Herniated disk disease is a condition that refers to a problem with a rubbery disc between the spinal bones. A herniated disk can occur in any part of the spine and can irritate a nearby nerve. Depending on where the herniated disk is, it can result in pain, numbness or weakness in an arm or leg.
- Sciatica Nerve Problems
Sciatica is a condition that affects the sciatic nerve, which is the largest nerve in the human body. The sciatica nerve directly affects your ability to control and feel your legs. When this nerve is irritated, you’ll experience sciatica. Sciatica causes an irritation, pinching or compression of a nerve in the lower back. An NCV test can help diagnose compression or damage in the sciatic nerve and can also help detect any problem with the nerve itself.
- Peripheral Neuropathy
Your peripheral nervous system connects the nerves from your brain and spinal cord, or central nervous system, to the rest of your body. The job of these nerves is to deliver signals about physical sensations back to your brain. Peripheral neuropathy refers to the conditions that result when nerves that carry messages to and from the brain and spinal cord from and to the rest of the body are damaged or diseased. A nerve conduction velocity test can help measure the extent of the damage to the nerve fibers.
- Carpal Tunnel Syndrome
Carpal tunnel syndrome causes numbness, tingling, or weakness in your hand and arm. Carpal tunnel syndrome occurs due to pressure on your median nerve, which runs the length of your arm, goes through a passage in your wrist called the carpal tunnel, and ends in your hand. An NCV test can diagnose nerve function in the median nerve and help a doctor determine the right treatment plan.
- Guillain-Barré Syndrome
Guillain-Barré syndrome is a rare but serious condition with the peripheral nervous system (PNS). The condition causes muscle weakness, reflex loss, and numbness or tingling in parts of your body. This condition may also often leads to paralysis, which is usually temporary. An NCV test can help diagnose GBS. Electrical signals along nerves affected by GBS are slower than others.
