Electromyography (EMG) is a diagnostic test that evaluates the health and function of your skeletal muscles and the nerves that control them. It’s one form of electrodiagnostic testing. That’s exactly what is an EMG test used to diagnose: it helps reveal whether the problem starts in your nerves, your muscles, the nerve root near your spine, or the tiny space where nerve meets muscle. In plain English, it shows where the signal breaks down so treatment can actually work. Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. Electromyography (EMG) tests the electrical activity in muscles to diagnose neuromuscular diseases like muscular dystrophy. It’s often performed alongside nerve conduction studies, which measure how electrical signals within the body travel down the nerves. Motor neurons are the nerve cells that send signals to your muscles to move. During the test, a needle probe is inserted into your muscle to measure its electrical activity. The EMG turns the...

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle.
