The present status of different computerized methods of automatic quantitative electromyography are reviewed. Interference pattern methods– turns analysis, spectral analysis –are efficient, but the results usually cannot be directly related to the physiological properties of the motor units. Integration analysis does not currently have a major role in diagnostic electromyography. Traditional measurement of single motor unit action potentials during weak contraction can be facilitated and made more objective with computer assistance, but only the lowest‐threshold motor units in the muscle are amenable to study. A new class of methodologies under development permit the decomposition of interference patterns into their constituent motor unit action potentials for measurement of configurational and behavioral properites. Patient data from these various methods can be statistically compared with normative data bases available on‐line in computerized electromyographs. Both qualitative and quantitative electromyography have applications in the neuromuscular electrodiagnostic examination.
