Nerve transmission speed (NCV) test is accomplished frequently at the same time as a EMG. In this test the nerve becomes electrically lively, while a second electrode determines the electric drive down from first to flow '. This is normally done with surface mark electrodes, which are set on the skin over the nerve at the different positions. An electrode energizes the nerve with a very mild electric drive. The resulting electrical activity is noted by the other electrodes. The distance between electrodes and the time, which it used for electric drives for the clearance between electrodes to
calculate the speed of the drive transmission. A reduced speed of the transmission indicates nerve to illness.
The NCV test is possibly used finds out the real nerve for example mental illness or the situation so as to the muscle affects by the nerve wound. The normal body temperature must by the maintenance be the NCV test, because the low body temperature reduces speed the nerve conduction. It is essential to get the proper diagnoses of the Amyotrophic Lateral Sclerosis patients.
