[Automatic analysis of needle EMG in the differential diagnosis of neuromuscular diseases]

A total of 112 muscles were studied in 68 patients with different neuromuscular diseases (7 nosological forms). The study was performed using an original programme of an automatic analysis of needle real-time electromyography and a specially designed automatic system on the basis of Soviet microcomputer "Electronika-60". On the basis of an automatic analysis of 17,834 potentials the authors identified 1,619 individual potentials of motor units. Measurement of all parameters (amplitude, duration, the number of phases in the potential and area) and calculation of correlations between individual parameters revealed significant differences of the mean values of the above parameters for each group of patients.
