Exercises of Semi-Occluded Vocal Tract in the Rehabilitation of Recurrent Paralysis: Presentation of Cases
Ejercicios de Tracto Vocal Semi-Ocluido en la Rehabilitación de Parálisis Recurrenciales: Estudio de casos
Main Article Content
The following work aims to present six cases of recurrent
unilateral vocal cord paralysis in paramedian position
that have been rehabilitated with semi-occluded vocal
tract exercises, belonging to the philosophic physiologic
trend, in contrast to the common rehabilitation with the
symptomatology tendency. These exercises are based
on the nonlinear vocal production theory that seeks to
restore the respiratory, laryngeal and resonance systems
throughout phonation. They improve the source-filter
interaction modifying the impedance of the vocal tract
by occluding and lengthening the previous. Vocal The
