The author presents a new concept and the results of simple assessment of EMG records by means of a universal set of parameters represented by two digital indices. The first descriptor determines the mean value of a single unit potential and it was obtained as a product of the mean values of potential duration and amplitude. The second descriptor determines the mean value of the interference tracing during maximal contraction of the muscle and it is the ratio of the mean amplitude to the mean density. The use of these two diagnostic indices makes possible an immediate evaluation of EMG records during the examination. The method is very sensitive and diagnostically reliable.
