Nerve Conduction Study (NCV)
A nerve conduction study (NCS) is a test commonly used 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.
These tests are reported by our team of neurologists comprising of Dr. Reena Thukral. At EHL Diagnostics we have the complete Neuro Lab which provides tests like EEG, EMG, NCV, BERA and Sleep Study.
Reasons for the test
Conditions that may be evaluated with NCV include, but are not limited to, the following:
- 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.
- Carpal tunnel syndrome. A condition in which the median nerve, which runs from the forearm into the hand, becomes pressed or squeezed at the wrist by enlarged tendons or ligaments. This results in pain and numbness in the fingers.
- Charcot-Marie-Tooth disease. A hereditary neurological condition that affects both the motor and sensory nerves. One characteristic is weakness of the foot and lower leg muscles.
- Herniated disk disease
- Chronic inflammatory polyneuropathy and neuropathy. These are conditions resulting from diabetes or alcoholism.
- Sciatic nerve problems
- Peripheral nerve injury
- Nerve conduction studies may also be performed to identify the cause of symptoms such as numbness, tingling, and continuous pain.
