title: Diagnostic contributions of the electromyogram.
abstract: When muscles contract, they generate electricity. This muscle electricity can be seen and heard on the electromyograph. Normal muscles generate a different type of electrical impulse than do paralyzed muscles, and for this reason the electromyograph is of great assistance in the diagnosis, prognosis and treatment of such conditions as poliomyelitis, nerve injuries and strokes.
