Abstract

The invention relates to medical diagnostics and in particular to the electromyographic measurement of muscle-nerve diseases. In electromyography measurement, muscle cell membranes simultaneously produce both diagnostic and disturbing signals (21, 30, 130). The measurement is used routinely to analyze the voltage difference between the tip (1 1) and the shaft section (12) of the measuring needle (10). In the method according to the invention, the voltage differences between the tip portion (1 1), the cannula portion (12) and the skin surface (40) are separated using two simultaneous channels ( 13, 41). This processing and analysis improves the selectivity of measurement and reduce the proportion of interfering transients (130) in the analysis results.
