Each nerve test takes just a few minutes to an hour, depending upon how many nerves are being tested. A number of nervous system diseases may reduce the speed of this impulse.

The time between the stimulation and response will be recorded to determine how quickly and thoroughly that the impulse is sent. After the exam the electrodes will be removed and your skin cleaned. You may feel a tingle or your muscles may twitch but this shock is not harmful. A stimulator will be held against your skin, which sends out a small electrical charge along the nerve. You will be resting on a cart or bed and electrodes will be taped to your skin. A peripheral nerve transmits information between the spinal cord and the muscles. The NCV evaluates the health of the peripheral nerve by recording how fast an electrical impulse travels through it. Most of the time the Nerve Conduction Velocity Test will accompany the EMG Test.

Other common patient complaints are pain with insertion of the electrode. There is a slight risk of minor, localized inflammation in muscles during the test. After the exam, you may feel tenderness in the tested muscles. Total testing time may range from just a few minutes to more than an hour, depending upon how many muscles are tested. Muscles chosen for the testing vary with the patient's symptoms and may be modified, depending on the results from the first muscles tested. After the first muscle is tested, the electrode may be inserted into another muscle. Nerve and muscle diseases alter the pattern of electrical activity in these muscles, which is record both audibly and on a computer screen. The electrode then records the activity during the insertion, while the muscle is at rest, and while the muscle contracts. A tiny needle, called an electrode, is inserted directly into a specific muscle belly. It can detect conditions such as tarsal tunnel syndrome, inflamed muscles and pinched nerves. It can diagnose diseases of the nerves and muscles.

The EMG portion of the test is used to record the electrical activity in your muscles. Your doctor typically will refer you to either a hospital or a neurologist to have the test performed. Commonly the EMG/NCV test is used to diagnosis one of the following: Tarsal Tunnel Syndrome, Peripheral Neuropathy, Neuromuscular disorders, Nerve palsy or Paralysis, and Radioculopathy. Your doctor will usually order this test when he suspects that there may be some type of problem with the nerve supply to your foot and leg. This test is used to test the nerves and muscles in your entire lower extremity. Common Disorders Electromyography (EMG) / Nerve Conduction Velocity( NCV)
