EMG-LAB computer system for routine electromyography.
The new computer aided program for fully automatic single MUAPs and IP analysis is described. This software programs called EMG-LAB represents the integrated system of IBM PC/AT computer with any kind of EMG machine. The individual MUAPs are automatically extracted, identified and measured on line, thanks to the sophisticated program based on statistical averaging. All the measured parameters like duration, amplitudes, areas, turns and phases are presented in computer display in a form of histograms. The summary of complete examination are presented in six parameters in form of histograms together with statistical values representing their distribution and variability. Those histograms represent the MUAPs waveforms remodeled during different disease processes. During maximum voluntary effort the interference pattern analysis is made on the new developed method. It allows to determine the parameters of different MU size, their quantity and intensity of recruitment. The most specific feature of this analysis concerns the information of the background activity, where the indirect data of single MUAPs and their parameters typical for given pathology could also be evaluated from interference pattern.
