Your body has a way of telling you when something’s off—numbness, tingling, weakness, or strange muscle twitches that just won’t quit. While some of these symptoms might be minor annoyances, others could be signs of an underlying nerve or muscle issue. That’s where EMG comes in.
Electromyography (EMG) is a diagnostic test that measures the electrical activity of muscles. It can be used to diagnose a variety of conditions that affect the muscles and nerves, such as carpal tunnel syndrome, muscular dystrophy, and pinched nerves.
