EMG/NCV (Electromyography/Nerve Conduction Velocity)
Underlying Problem Requiring an EMG/NCV:
EMG (electromyography) is a test used to measure the electrical activity of a patient\'s muscles. NCV (nerve conduction velocity), on the other hand, measures the intensity and the speed of the electrical signals that travel along the nerves, in addition to the reaction time for a response to these signals. Patients who require an EMG/NCV generally need a diagnosis relating to some sort of neuromuscular disorder. They help find the cause of a variety of conditions relating to muscles, such as paralysis, pain, spasms, and weakness. Results can also help to pinpoint the location of the problem, whether it is in the muscles themselves or is originating from the spinal cord or nerves.
EMG/NCV is performed by a neurologist
. He or she is not only capable of conducting the test but can also interpret the results once the results have been obtained. The doctor will ask the patient to sit or lie down, depending on the area being tested. In the case of an EMG, a tiny needle will be inserted into a muscle in order to stimulate and measure electrical activity. An NCV will require two electrodes to be placed on the skin, and measurements will be taken as an electrical current travels the nerve between them.
There is little to no recovery time required after an EMG/NCV. At most, a patient may feel some tingling as a result of the electrical current introduced during the test, but this will not generally outlast the appointment. The patient can typically return home to all daily activities immediately.
