Brief description of trial (Data source: BASEC)
Bei 12 gesunden Männern und Frauen werden die Zwerchfellnerven im Rahmen von drei Laborbesuchen systematisch mit variierender Stimulationsfrequenz, -intensität und -spule am Hals und im oberen
Brustbereich stimuliert. Bei einem der Laborbesuche wird als Vergleich separat auch der Oberschenkelmuskel stimuliert. Ziel dieser Studie ist die Bestimmung des effektivsten Protokolls zur nicht-invasiven Aktivierung des Zwerchfells mittels wiederholter magnetischer Stimulation der
Phrenikusnerven.
Health conditions investigated(Data source: BASEC)
Es gibt medizinische Situationen - wie z.B. künstliche Beatmung über mehrere Tage – durch welche Kraft und Funktion des Hauptatmungsmuskels, d.h. des Zwerchfells, reduziert werden kann, was eine längere Entwöhnungsphase vom Beatmungsgerät, eine reduzierte Lebensqualität und Erholungsprognose von Patienten bewirken kann. Um diesem Funktionsverlust entgegenzuwirken, wollen wir mit dieser Studie in einem ersten Schritt herausfinden, mit Protokoll das Zwerchfell am besten nicht-invasiv, mittels magnetischer Stimulation der Phrenikusnerven aktiviert werden kann.
