Abstract
Coughing produces pulses of pressure in the cerebrospinal fluid. A mathematical model is proposed for the examination of the propagation of waves through the cerebrospinal-fluid pathways. The effects due to differing degrees of obstruction of the spinal-fluid pathway (blockage) on the attenuation factors and wave speeds are discussed as are the effects due to vibrations of the elastic dura.
Sommaire
La toux produit des impulsions de pression dans le liquide cérébrospinal. Cet article suggère un modèle mathématique pour l'examen de la propagation des ondes à travers les voies de passage du liquide cérébrospinal, et il examine les effets de différents degrés d'obstruction des voies de passage du liquide spinal (blocage) sur les facteurs d'affaiblissement et les vitesses de propagation des ondes, ainsi que les effets des vibrations sur la dura élastique.
Zusammenfassung
Durch Husten werden Druckimpulse in der zerebrospinalen Flüssigkeit erzeugt. Zur Untersuchung der Fortpflanzung von Wellen durch die zerebrospinalen Flüssigkeitskanäle wird ein mathematisches Modell vorgeschlagen. Die auf die verschiedenen Behinderungsstärken für die Spinalflüssigkeitskanäle (Blockierungen) zurückzuführenden Auswirkungen auf die Dämpfungsfaktoren und Wellengeschwindigkeiten werden besprochen, ebenso die Auswirkungen von Schwingungen der elastischen Dura.
