title: [Analysis of EMG records obtained by using an "Anops" computer (their usefulness in the diagnosis of neuromuscular diseases].
abstract: The studied group included 179 individuals: a control group of 82 subjects, myopathy patients (55) and neurogenic atrophy cases (42). The records were obtained from 4 muscles (biceps, 1st interosseous muscles, quadriceps muscle, anterior tibialis muscle) using the method of automatic EMG analysis and quantitative conventional method. The obtained results demonstrated that in the control group Anops analysis showed no significant differences in the electromyographic parameters of a given muscle in three age groups (15-30, 31-45 and 46-60 years). The values of the mean duration of single potentials were calculated by the automatic method and in the control group they were shorter (by a mean value of 15%) than the mean duration of these potentials calculated by the conventional method. In cases of neuromuscular diseases the obtained measurements differentiated the normal records from the pathological ones, and myogenic from neurogenic lesions. The EMG parameters in the automatic analysis differentiating most evidently normal EMG from pathological EMG were: amplitude and mean duration of single potentials. These results seem to demonstrate the usefulness of automatic analysis of EMG records.
