Abstract:
Semioccluded vocal tract exercises, postures that to enlarge and narrow vocal tract, are used to achieve economic vocal production,reducing vocal fold impact stress and vocal effort, are widely easy application in warm up, training and voice therapy.
Describe and compare self-assessment of voice, vocal quality glottal source and usual fundamental frequency after semioccluded vocal tract exercises (SOVT) lip trills and hand over mouth in teachers, in Cordoba, 2019
Descriptive, cross-sectional, quasi-experimental study. Sample: n = 46 female teachers, mean age 38.08, after acceptance of informed consent, 23 participants (n1) performed lip trills exercise (LTE) and 23 (n2) hand over mouth (HOM). To measure self-assessment of the voice, participants completed the visual analog scale (VAS) and self-report of vocal tract discomfort (VTD), vocal quality was measured through the G parameter (degree voice alteration) of the auditory-perceptual scale. GRBAS, usual fundamental frequency (U-F0) was recorded using the “Voice Tools” software. All measurements were recorded PRE and POST exercises, statistical analysis was performed in infostat 2020.
Both exercises showed changes measurens, in the self-assessment of the voice, for LTE, VAS and VTDi they registered a decrease of -1.83 pts and -6.39 pts respectively, for HOM, VAS decreased -2.13 pts. and VTDi -10.74 pts. For vocal quality, the G parameter for both LTE and HOM, registered a decrease of -0.10 and -0.35 pts respectively. U-F0 values increased, for LTE (+3.71 Hz) and HOM (+9.44 Hz). Significant changes were observed in all measures for HOM, VAS (p = <0.0001) VTDi (p = <0.0001) G (p = 0.0052) and U-F0 (p = 0.02).
The lip trills and hand over mouth exercises produced positive changes self-assessment of the voice, vocal quality and usual fundamental frequency of the teachers; these changes were statistically significant only for hand over mouth.

Resumen: Los ejercicios de tracto vocal semi-ocluido, posturas que buscan alargar u ocluir el tracto vocal, se utilizan para lograr una producción vocal económica, con menor esfuerzo y estrés impacto en los pliegues vocales, son de fácil aplicación para el calentamiento, entrenamiento y terapia vocal en docentes. Describir y comparar el estado de la autopercepción de la voz, la calidad vocal de la fuente glótica y la frecuencia fundamental habitual luego de la realización de ejercicios de tracto vocal semi-ocluido (TVSO) de vibración de labios y firmeza glótica en docentes, en Córdoba, 2019. Estudio descriptivo transversal, cuasi experimental. Muestra: n=46 docentes de sexo femenino, edad media 38,08, posterior a la firma de consentimiento informado, 23 participantes (n1) realizaron ejercicio vibración de labios (EVL) y 23 (n2) ejercicio firmeza glótica (EFG). Para determinar la autopercepción de la voz los participantes completaron escala análoga visual (EAV) y autoreporte disconfort del tracto vocal (DTV), la calidad vocal se midió a través del parámetro G (grado de afección de la voz) de la escala auditivo-perceptiva GRBAS, la frecuencia fundamental habitual (F0-hb) se registró mediante el software “Voice Tools”. Las variables se registraron PRE y POST ejercicios, se realizó análisis estadístico en infostat 2020. Ambos ejercicios evidenciaron cambios en las variables investigadas, en la autopercepción de la voz, en el EVL la EAV y DTVi registraron un descenso de -1,83 pts y -6,39 pts respectivamente, en el EFG la EAV descendió -2,13 pts. y DTVi -10,74 pts. En la calidad vocal, el parámetro G tanto para el EVL como el EFG, registraron un descenso de -0,10 y -0,35 pts respectivamente. Los valores de F0-hb se incrementaron, para el EVL (+3,71 Hz) y EFG (+9,44 Hz). Se observaron cambios significativos en todas las variables para el EFG, EAV (p=<0,0001) DTVi (p=<0,0001) G (p=0,0052) y F0-hb (p=0,02). Los ejercicios de vibración de labios y firmeza glótica produjeron cambios positivos en la autopercepción de la voz, en la calidad vocal y en la frecuencia fundamental habitual de los docentes, estos cambios fueron estadísticamente significativos solamente para el ejercicio de firmeza glótica. .
