Nerve Conduction Velocity or NCV, studies the quality and speed of conduction in the tested nerves. During this test, a nerve will be stimulated with a mild and very short electrical impulse on your skin and surface electrodes will capture and record the electrical activities far from the site of stimulation. This will provide valuable information about the quality, function and speed of the conduction in the tested nerves.
Burning sensation, numbness, pain, or change in sensation may prompt your physician to order a nerve conduction study. This test may detect certain nervous system disorders secondary to a disease, such as different types of peripheral neuropathies and inflammation of the nerves, or due to nerve injuries or compression, like carpal tunnel syndrome.
A nerve conduction velocity test is often followed by an electromyography test to rule out or include muscular sources of a possible symptom.
Electromyography, or EMG, involves testing the electrical activity of muscles at rest and during contraction. It is a valuable component of your physical examination that provides reliable information to help your doctor diagnose a suspected abnormality.
EMG testing may determine whether the tested muscles are functioning properly or not. It may also differentiate between muscular conditions or dysfunctions due to a nerve disorder as the cause of your pain and/or weakness.
EMG results may determine the source of an abnormal electrical activity of a muscle due to diseases of the muscle like muscular dystrophy, inflammation of muscle, or secondary to conditions like a pinched nerve, peripheral nerve damage, disc herniation, amyotrophic lateral sclerosis (ALS), myasthenia gravis or others.
