With nerve conduction studies, you may feel a quick, burning pain, a tingling feeling, and a twitching of the muscle each time the electrical pulse is given. It feels like the kind of tingling you feel when you rub your feet on the carpet and then touch a metal object. The tests make some people anxious.
Often, EMG testing is performed with another test that measures the conducting function of nerves, called a nerve conduction study (NCS). These electrodiagnostics tests (EMG and NCS) are often performed at the same office visit and by the same personnel, the risks and procedures generally apply to both tests. In some medical conditions the electrical activity of the muscles or nerves is not normal.
