En outre, l'unité de formation de signaux se présente comme les unités suivantes reliées en série : une unité de commande de fréquence de signaux, un générateur formateur, un vibreur et deux inverseurs entre lesquels on a connecté en série un générateur de paquets d'impulsions et un additionneur. L'amplificateur de puissance à pont est relié en parallèle par deux entrées au second inverseur. En utilisant le stimulateur électrique, il est possible d'effectuer une action pulsée sur les organes du pelvis avec la fréquence d'oscillations dans un paquet de 2,2 à 2,5 kHz, l'amplitude allant jusqu'à 18 V et la longueur du paquet d'impulsions de 2-8 Hz. L'invention permet d'optimiser l'action effectuée sur le patient en augmentant la précision de réglages afin de simplifier la conception structurelle et d'améliorer la facilité de la conduite des procédures.
