Effective use of EMG parameters in the assessment of neuromuscular diseases

From the EMG signal measured in four groups of pathologies, time and frequency domain parameters were obtained. Separation of the four groups by means of these parameters was attempted on the basis of a multivariate approach. Use of Discriminant Analysis provided evidence of the superiority of the time domain to frequency domain parameters and showed, however, that the use of time and frequency parameters jointly, highly improved discrimination. It also allowed one to suggest a three-step strategy for classification of cases of unknown ethiopathology. © 1982.
