Primary Outcome Measures:
  • Subjects were submitted to perceptual analysis and laryngostroboscopic exams before and after the use of vocal techniques. [ Time Frame: twenty minutes ]

Enrollment: 32
Study Start Date: July 2008
Study Completion Date: December 2008
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Detailed Description:
Vocal techniques have been used, but few studies had as their aim to effectively verify its use and effect produced in voice and the larynx. The objective of this clinical and experimental study was to verify the immediate effect of vocal techniques: vibration, nasal sound and articulation. Material and method: 32 female subjects with normal to mild dysphonia participated in the research, with ages from 20 to 45 years. All subjects were submitted to realization of vocal techniques of vibration of the lips, articulation and nasal sounds for twenty minutes. The subjects were submitted to record the voice and laryngostroboscopic exams for perceptual analysis and laryngostroboscopic exams before and after the use of vocal techniques.
