NCV the Unknown Facts

NCV commonly known as Nerve Conduction Velocity is primarily a test utilized for identifying indications of nerve injury

. A critical sign that may force a health care expert to organize a nerve conduction velocity test for a patient includes lack of feeling' or an itchy sensation'. This test can be used to find out complex nerve disorders (like peripheral neuropathy and mononeuritis multiplex) or situations whereby nerves are affected by perfunctory compression injury (Like carpal tunnel syndrome and compression neuropathy). For performing the NCV test a standard body temperature should be preserved since low body temperatures slows down nerve conduction.

During the NCV test the nerve is actually electrically enthused and the electrical impulse downstream from enthuse is calculated. This test is done by using surface patch electrodes, which are positioned on the skin over the nerve at different areas. One electrode enthuse the nerve with a very gentle electrical impulse. The consequential electrical action is documented by the other electrodes. The distance among the electrodes and the time it takes for electrical impulses to move between electrodes are used to estimate the velocity of impulse transmission (nerve conduction velocity). A diminished speed of transmission proves presence of nerve disease.

From the perspective of the patient the electrical impulse may feel like an electric shock. Based on how strong the spur is, a patient can feel it to varying level, and to a certain extent it can be painful. Once the test is completed the patient will not feel any pain.
