During an Electromyography study, a very small pin is inserted in the muscle that helps us evaluate the condition of your muscles. Nerve and muscle disorders cause the muscles to react in abnormal ways. Nerves control the muscles in the body by electrical signals (impulses), and these impulses cause the muscles to react in specific ways. ![]() An Electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction.This impulse produces a visual signal on a computer monitor and when analyzed it can provide information about the condition of the nerve. The response is measured by a second set of electrodes applied to the surface of the skin. Mild electrical stimulation is administered to the skin directly overlaying the nerve. ![]()
