Resumen

Introducción

La terapia de voz es una práctica que no está ampliamente fundamentada en la evidencia investigativa; la valoración y el seguimiento de los programas de rehabilitación se apoyan casi exclusivamente en el análisis perceptual y pocas evaluaciones acústicas reportan medidas que no se han interrelacionado entre sí para determinar grados de riesgo vocal en diferentes poblaciones con disfonía.

El objetivo de esta investigación fue valorar acústicamente el efecto de 2 tipos de terapia vocal (mixta y directa) en personas con disfonía funcional empleando el índice de perturbación vocal integrado.

Método

Se seleccionó una muestra de 20 personas entre los 20 y 60 años con disfonía funcional; se evaluó toda la muestra mediante análisis acústico con el software Anagraf y se fraccionó la muestra en 2 grupos, el primero recibió terapia vocal mixta y el segundo únicamente terapia vocal directa. Se evaluaron acústicamente las voces, posterior a la terapia, y se comparó el efecto de los 2 tipos de intervención propuestos.

Resultados

El índice de perturbación vocal integrado se encontró alterado para la mayor parte de la muestra de ambos grupos, preterapia vocal. Finalizada la terapia tanto mixta como directa, se encontró que este índice clasificó voces en rangos de normalidad y voces en riesgo disminuyendo su grado de alteración.

Conclusión

El índice de perturbación vocal integrado se modificó favorablemente para ambos grupos de terapia. No obstante, esta modificación fue estadísticamente significativa para el grupo que realizó terapia vocal mixta.

Abstract

Introduction

Voice therapy is a practice that is not extensively based on research evidence; the assessment and monitoring of rehabilitation programmes are generally based on perceptual analysis, and few acoustic measures have not been correlated with each other to determine the extent of vocal risk among different kinds of populations with dysphonia.

The aim of this research was the acoustic assessment of the effect of 2 types of voice therapy (mixed and direct) in individuals with functional dysphonia using the integrated vocal disturbance index.

Method

A sample of 20 functional dysphonic individuals aged between 20 and 60 years was selected. The individuals were assessed through an acoustic analysis using Anagraf software. The sample was split into 2 groups; the first one received mixed voice therapy and the second only received direct voice therapy. The post-therapy voices were acoustically assessed, comparing the effect of the techniques proposed.

Results

The integrated vocal disturbance index was found to be altered for most of the individuals in both groups before receiving voice therapy. On completion of the mixed and direct voice therapy, it was found that the index classified the voices into normal and at risk, decreasing their extent of disturbance.

Conclusion

The integrated vocal disturbance index was favourably modified for both therapy groups. However, this was statistically more significant for the group that received mixed voice therapy.

Portable Music Players Associated with Hearing Loss in Children

​Portable music player use has been linked to high-frequency hearing loss in children aged 9 to 11 years, according to a new study (JAMA Otolaryngol Head Neck Surg. 2018 Aug 1;144(8):668-675). Researchers in Rotterham, the Netherlands, measured the pure-tone audiometry of more than 5,000 children and assessed their portable music player (PMP) use via parent surveys, including how often they listen to music with headphones per week, the listening time on an average day, and the usual volume of the PMP. Of the 3,116 children included in the analyses, 443 (14.2%) children had audiometric notches or high-frequency hearing loss in one or both ears. Hearing-related symptoms were reported for 11.3 percent of the children, 0.8 percent of whom had frequent to permanent symptoms. Overall, PMP use was reported in 40 percent of the children, and these children generally listened to less than one hour per day and on normal volume. Close to five percent of the parents reported that their children used PMPs on a nearly daily basis. Lead study author Carlijn le Clercq a PhD candidate at Erasmus University Medical Center in Rotterdam, said, "Although we cannot conclude from this study that music players caused these hearing losses, it shows that music exposure might influence hearing at a young age."​
