Patients present with a lot of complaints, but the ones that require a nerve test (NCV/EMG) are those that complain of neck or back pain with radiating pain in the arm or legs, muscle weakness or involuntary twitching of muscles.
An electromyogram, or EMG, is a test that checks the response of muscles to messages sent by the nerves. The test has two components, the first is the NCV (nerve conduction test), the second component is the needle examination called an electromyogram. An NCV/EMG test is a diagnostic test that your doctor may order to assist in obtaining additional information in order to assist him/her in making the right diagnosis regarding your medical condition.
