An abnormal EMG result means there is a problem in an area of muscle activity—turning on and off, when it is active, how much it is active, if it is more or less active, and fatigue. This can offer a clue in diagnosing various nerve and muscle conditions. Learn more in 10 Conditions Diagnosed With an EMG.
