The value of automatic analysis for quantitative electromyography.
The value of automatic analysis for quantitative electromyography. Acta Physiol. Pol., 1979, 30 (2): 231--239. The authors describe the automatic analysis of EMG records by means of minicomputer ANOPS-101. Computer works on-line during EMG examination, being directly connected to the output of electromyograph. During slight voluntary muscle contraction 3 histograms could be obtained--namely: distribution of MUAP duration, number of their phases and their amplitudes. During maximum voluntary contraction two more histograms could be obtained--namely: distribution of amplitudes of spikes and distribution of intervals between spikes. These five histograms are displayed on the screen and the mean values are automatically calculated. As a result all quantitative EMG data are obtained which are sufficiently accurate for differentiation between pathological and normal recordings and which help to distinguish the myogenic atrophy from neurogenic one.
