![]() ![]() With the electrode in place, the patient is asked to slowly contract the muscle-for example, by bending the arm-with gradually increasing force, while the electrical activity is being recorded. In an EMG, a physician or technician inserts a very fine needle, which serves as an electrode, through the skin into the muscle.
