Know the NCV test … and the diseases it detects


The nerve conduction velocity test (NCV) measures how fast the electrical impulse moves through the nerves, and this test can determine nerve damage and detect many diseases, including: herniated disc, carpal tunnel syndrome, and others. And its uses, according to the US University of Rochester website.


Diseases revealed by the NCV

The NCV nerve conduction velocity test is often used in conjunction with an EMG to find the difference between a nerve disorder and a muscle disorder, the NCV detects any problem with the nerve, while the EMG detects whether the muscles are working the right way in response to a nerve stimulation.

The diseases or health problems that can be verified with the NCV include:

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 a tingling sensation in the legs.

Carpal tunnel syndrome is a health problem in which the median nerve, which extends from the forearm to the hand, is subjected to pressure or compression at the wrist due to enlargement of tendons or ligaments, causing pain and numbness in the fingers.


Charcot-Marie-Tooth disease, an inherited neurological condition that affects both motor and sensory nerves, causes weakness in the foot and leg muscles.

Herniated disc disease: This health problem occurs when the fibrous cartilage that surrounds your vertebrae is broken. The center of each cartilage, which contains a gel, is pushed outward, and this puts pressure on the spinal nerve and causes pain and nerve damage.

Nerve damage “neuropathy”: This condition may occur from many health problems, such as diabetes, chemotherapy, and autoimmune disorders such as chronic neuritis, or alcoholism. Symptoms may include numbness or tingling in one or many nerves in Same time.

Sciatic nerve problems: There are many causes for sciatic nerve problems, and the most common is a bulging or rupture of the intervertebral disc that presses on the nerve roots leading to the sciatic nerve. This often results in pain, tingling, or numbness.

Nerve conduction studies can also be conducted to find out the causes of persistent numbness, tingling and pain symptoms.
