EMG: These letters stand for: E = Electro (Electrical) M = Myo (Muscle) G = Gram (Measure).


Background Information: Your nerves conduct electricity just like an electric wire; they bring sensation to your skin and trigger muscle function. The EMG (and nerve study) measure the amount of electricity in nerves and muscles. A disease in the nerves or muscles may be reflected by an abnormality in the “EMG”. In this fashion we are able to detect if there is a problem with these structures, where the problem is, and how severe it is.
