Why is the Test Performed?

EMG is most often used when people have symptoms of weakness and examination shows impaired muscle strength. It can help to differentiate primary muscle conditions from muscle weakness caused by neurologic disorders.

EMG can be used to differentiate between true weakness and reduced use due to pain or lack of motivation.
