If you are experiencing tingling, numbness or muscle weakness, our neurodiagnostic lab offers a diagnostic test that can give your doctor valuable information about your problem. An NCV/EMG test assesses the health of nerve cells and muscles that control movement by transmitting electrical signals from the nerves and muscles and recording, activity or inactivity to determine weakness in muscle tissue or nerves.
A NCV/EMG test is an excellent diagnostic tool used to confirm or rule out diseases or conditions, such as muscular dystrophy, polymyositis, myasthenia gravis, carpal tunnel syndrome, peripheral neuropathy, amyotrophic lateral sclerosis, polio, as well as a herniated disk.
Learn what to expect from NCV/EMG
During a nerve conduction study, the technologist tapes electrodes to the skin. They then measure speed and strength between the two electrodes through a series of mild electrical impulses.
The EMG is another component of the test. In this part of the study, the physician will insert a tiny needle electrode into the patient’s muscle that is suspected of causing the problem. The physician will then ask the patient to contract and release the muscle several times to test the area. The electrode sends signals to contract the muscle and record the response, using a numerical value to show functionality.
NCV/EMG test results can reveal nerve dysfunction, muscle dysfunction, or problems with nerve-to-muscle signal transmission.
While there is no recovery period following the test, some patients may have minor bruising where the needles were inserted.
NCV/EMG testing is performed in the WakeMed Neurodiagnostic Lab at our, Raleigh Campus, located on the 1st floor in the Medical Office Building.
