What is An Electromyography?

• Electromyography (EMG) is a diagnostic procedure that evaluates the health condition of muscles and the nerve cells that control them. These nerve cells are known as motor neurons. They transmit electrical signals that cause muscles to contract and relax. An EMG translates these signals into graphs or numbers, helping doctors to make a diagnosis.
• Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle, and the electrical activity of muscle during rest, slight contraction and forceful contraction.
