EMGs can detect abnormal muscle electrical activity in many diseases and conditions, including inflammation of muscles, pinched nerves, damage to nerves in the arms and legs, disc herniation, and degenerative diseases such as muscular dystrophy, Lou Gehrig's disease and Myesthenia gravis, among others.
Electromyogram (EMG). An EMG measures the electrical activity in a muscle in response to stimulation. It is used in conjunction with a neurological exam to help physicians diagnose a wide range of problems, including: 1  Nerve damage from disk compression in the neck or back.2  Nerve compression from carpal tunnel syndrome.lectromyogram (EMG).
