DESPITE its complexity, the use of electronics has become fashionable as an aid in establishing diagnoses in various neuromuscular disorders. At the present time electromyography seems to be taking precedence over all other electrodiagnostic methods, even though the older methods are as informative—sometimes even more so—and require simpler apparatus and less technical knowledge. In order to compare the efficacy of these methods, we analyzed the pertinent data accumulated on patients at the Veterans Administration Hospital, Hines, 111.

The electrical examination is usually performed by a neurologist assisted by a physical therapist trained in the technique. The physician requesting the electrical evaluation submits a brief clinical summary and the reason for the examination. The complete electrical examination includes stimulation studies of the involved muscle with both galvanic and faradic currents, commonly called electrodiagnosis, and studies of electrical potentials of the muscle in the electromyographic phase of the examination.
