Electromyogram is a test that is used to record the electrical activity of muscles and nerves. EMGs are used to detect abnormal electrical activity that can occur in many diseases and conditions including inflammation of muscles, pinched nerves, peripheral nerve damage-damage to nerves in the arms and legs-, disc herniations and other conditions. It can be very helpful to diagnose your problem.
