The benefit of electromyography of the muscles is that it can be used as a diagnostic procedure that a doctor or researcher can use to evaluate the health status of that muscle and the neurons that control it. These neurons are known as motor neurons. The electrical signals cause the muscles to contract and relax and the EMG values convert these signals into graphs or numbers which help doctors and researchers to diagnose muscle and nerve function.
