Nerve Conduction Velocity
Nerve conduction velocity (NCV) is the speed at which electrical impulses travel through a nerve. With that said, an NCV test is a diagnostic procedure used to measure nerve injury or damage caused by a variety of injuries and conditions in adolescents and adults. Common symptoms you may be experiencing due to nerve damage include muscle cramping and tightening, pinching, and/or numbness. At OrthoSC, our highly trained and experienced physiatrists can help you overcome your ailments by conducting an NCV test, which assists in finding the source of abnormal nerve function in your body.
Our specialists perform a nerve conduction velocity test by placing an electrode on the skin, over the nerve suspected of damage or injury. Additional electrodes are placed on the muscle tissue stimulated by the nerve. Electrical impulses are then sent through the primary electrode and into the skin. The electrodes surrounding the primary electrode record the result of the electrical impulse. Please note, while the impulse is not dangerous, it may cause discomfort in some patients. Furthermore, NCV is measured by the time it takes for the impulse to travel between the electrodes. The slower the velocity, the more likely it is that damage or injury to the nerve has occurred.
