Title (EN) METHOD AND DEVICE FOR SELECTIVE MULTICHANNEL MEASUREMENT IN ELECTROMYOGRAPHY
(FR) PROCÉDÉ ET DISPOSITIF DE MESURE MULTICANAL SÉLECTIVE EN ÉLECTROMYOGRAPHIE
Abstract:
(EN) 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.
(FR) L'invention concerne le diagnostic médical et en particulier la mesure électromyographique de maladies musculaires-nerveuses. Dans la mesure d'électromyographie, les membranes de cellules musculaires produisent simultanément à la fois des signaux de diagnostic et de perturbation (21, 30, 130). La mesure est utilisée en routine pour analyser la différence de tension entre la pointe (11) et la section arbre (12) de l'aiguille de mesure (10). Dans le procédé selon l'invention, les différences de tension entre la partie pointe (11), la partie canule (12) et la surface de peau (40) sont séparées à l'aide de deux canaux simultanés (13, 41). Ce traitement et cette analyse améliorent la sélectivité de mesure et réduisent la proportion de transitoires d'interférence (130) dans les résultats d'analyse.
