What is Electromyography (EMG)?
Electromyography or EMG is a specialized procedure to detect and measure the information flow between the brain and nerves. Our muscles move in accordance with the signals they receive from the brain. The purpose of EMG is to measure how well they are responding to the signals sent from the patient's brain. The test is done by inserting a needle-electrode
