![]() In some cases, this may be performed along with an electromyography (EMG), which measures electrical activity in the muscles. The speed is then calculated by measuring the distance between electrodes and the time it takes an electrical impulse to travel between electrodes. All resulting electrical activity is recorded for each individual nerve being tested. During the test, a pair of electrode patches are applied to your skin near the nerve: one stimulates the nerve with a mild electrical impulse, while the second electrode records it. The intention is to identify any nerve damage that stops this movement from occurring as it should. How Does an NCV Test Work?Īn NCV, which can also be called a Nerve Conduction Study (NCS), works by measuring electrical impulses as they move through your nerve. If it’s recommended you undergo this test, read on to understand what to expect and what possible outcomes this test can have. ![]() These tests are used to look for and diagnose nerve problems and related muscular issues. ![]() But if you are experiencing symptoms consistent with a neurological problem, you may be sent for something known as a Nerve Conduction Velocity (NCV) Test. These tests are versatile and can be used to look for anything from a muscle strain to a broken bone. ![]() When it comes to diagnostic imaging, you probably first think of something like an x-ray, or even an MRI. ![]()
