Why do I need to have electromyogram tests?

Deborah Davis
OBGYN (Obstetrics & Gynecology)
An electromyogram test(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 disorders.  The EMG can also be used to detect true weakness, as opposed to weakness from reduced use because of pain or lack of motivation.  EMGs can also be used to isolate the level of nerve irritation or injury.
