What Is Involved in a Neurological Nerve Conduction Test?


Quick Answer

A neurological nerve conduction test involves measuring the speed in which conduction of an electrical impulse travels through a nerve, explains Johns Hopkins Medicine. The test helps medical professionals determine the extent or existence of muscle or nerve destruction or damage.

A neurological nerve conduction test involves stimulating a nerve with electrode patches placed on the skin, according to Johns Hopkins Medicine. An electrode is activated to stimulate the nerve with mild electrical impulses, and the patches record the results. The test calculates the speed of the nerve conduction velocity by noting the time it takes for the impulses to travel between electrodes.

Testing the neurological nerve conduction helps medical professionals determine neuropathy, or damage to the nerve, often following an injury or contusion to one or more nerves, states Johns Hopkins Medicine. The test is often used to monitor the progression of diseases such as Guillain-Barre syndrome, Charcot-Marie-Tooth disease, carpal tunnel syndrome or chronic inflammatory polyneuropathy. People with pinched nerves, sciatic nerve problems and herniated disk disease often undergo this procedure.

A neurological nerve conduction test typically offers low risk for patients, depending on their medical condition, notes Johns Hopkins Medicine. Patients with a pacemaker or cardiac defibrillator may need to undergo precautions in consultation with a medical professional before engaging in a neurological nerve conduction test.
