What is EMG?

EMG - (Electromyography)

EMG is a diagnostic study that that is used to record the electrical activity of muscles and provides information about the function of the muscles in your body. An EMG is often performed when patients have unexplained muscle weakness.

The EMG helps to distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve impingement.


How is the test performed?

During the EMG, the electrical activity is detected by a minute needle (which serves as an electrode). The activity is displayed visually on an oscilloscope and may also be detected audibly with a speaker.


How will the test feel?

Most patients experience only a small amount of discomfort when the needle is inserted. The muscle or muscles being tested may be slightly sore for a day or two after the procedure.
