What is NCV test?

NCV (nerve conduction velocity) test is a neurodiagnostic test that measures the speed and strength of nerve signals as they travel between the brain, spinal cord, and muscles. The test is used to diagnose and monitor conditions affecting the nerves, such as carpal tunnel syndrome, peripheral neuropathy, and radiculopathy.

How NCV test is done?

During an NCV test, electrodes are placed on the skin overlying the nerves being tested. The electrodes emit a small electrical impulse that stimulates the nerve, and another electrode records the resulting signal. The test measures the time it takes for the nerve signal to travel between the two electrodes, and the strength of the signal. The test typically takes about 30-60 minutes, depending on the number of nerves being tested.

Why NCV test is done?

NCV tests are safe and generally well-tolerated, although some patients may experience mild discomfort during the application of the electrodes or during the electrical stimulation of the nerves. The results of the test are usually interpreted by a neurologist or other healthcare provider trained in neurophysiology, who can use the information to diagnose and treat the patient's condition.

Some specific conditions that may be diagnosed or monitored with an NCV test include:

Overall, NCV tests are an important diagnostic tool for identifying and monitoring conditions affecting the nerves, and can help the doctor to develop individualized treatment plans to address each patient's unique needs.
