Electromyopgraphy (EMG)

Electromyopgraphy (EMG) is a diagnostic technique that uses a machine (called an electromyograph) to measure the electrical activity of skeletal muscles, The electrical measurements of muscles are used to detect muscular abnormalities and neuromuscular diseases. Electrodes are placed directly on the skin or a small censored needle is injected into the muscle. The electrical activity of the muscle is recorded by the electromyograph which produces the record (called a electromyogram). This record of activity can show abnormalities which can be used to diagnose a neuromuscular disorder. EMG is also used as a control for individuals using prosthetic limbs.
