          Abstract

          RESUMEN Objetivo: Evaluar si la hidratación combinada (sistémico y superficial) disminuye síntomas vocales y mejora la eficiencia glótica en una muestra de estudiantes de Logopedia. Material y Métodos: Estudio cuasi-experimental con grupo Hidratación (N=20) y grupo Control (N=19) con valoración pre y post-hidratación (ingesta de agua 1.500 ml/día e inhalaciones dos veces/día durante una semana). Se analizaron factores deshidratantes relacionados con la voz (uso vocal, tabaco, alcohol, café, respiración bucal), síntomas vocales y eficiencia glótica a través del Tiempo Máximo Fonación, Fo, Jitter % y Shimmer %, usando Multi-Dimensional Voice Program (MDVP). Resultados: Grupo Hidratación disminuyó significativamente sequedad (p = 0,013), carraspeo (p = 0,005), fatiga vocal (p = 0,015), dolor faríngeo (p = 0,009), Shimmer % (p = 0,048) frente al grupo Control que sólo disminuyó el carraspeo (p = 0,02). Conclusiones: La hidratación combinada puede ser una medida útil para mejorar la salud vocal de los futuros logopedas.

          ABSTRACT Objective: To evaluate if a combined hydration (systemic and superficial) decreases the vocal symptoms and improves the glottic efficiency in a sample of university students of Speech therapist. Material and Methods: Quasi-experimental study with Hydration group (N=20) and Control group (N=19) with pre and post-hydration assessment (water intake 1.500 ml/day and steam twice/day for a week). Voice-related dehydrating factors (vocal use, tobacco, alcohol, coffee, oral breathing), vocal symptoms and glottic efficiency through Maximum Phonation Time, Fo, Jitter % and Shimmer %, using Multi-Dimensional Voice Program (MDVP) were analyzed. Results: Hydration group significantly decreased dryness (p = .013=, throat clearing (p = .005), vocal fatigue (p = .015), pain throat (p = .009) and Shimmer % (p = .048) compared to the Control group, which only decreased throat clearing (p = .02). Discussion: The combined hydration may be a useful measure to improve vocal health for future speech-language-pathologists.

          Recommended Protocols for Instrumental Assessment of Voice: American Speech-Language-Hearing Association Expert Panel to Develop a Protocol for Instrumental Assessment of Vocal Function.

          The aim of this study was to recommend protocols for instrumental assessment of voice production in the areas of laryngeal endoscopic imaging, acoustic analyses, and aerodynamic procedures, which will (a) improve the evidence for voice assessment measures, (b) enable valid comparisons of assessment results within and across clients and facilities, and (c) facilitate the evaluation of treatment efficacy.

            Vocal fold epithelial barrier in health and injury: a research review.

            Vocal fold epithelium is composed of layers of individual epithelial cells joined by junctional complexes constituting a unique interface with the external environment. This barrier provides structural stability to the vocal folds and protects underlying connective tissue from injury while being nearly continuously exposed to potentially hazardous insults, including environmental or systemic-based irritants such as pollutants and reflux, surgical procedures, and vibratory trauma. Small disruptions in the epithelial barrier may have a large impact on susceptibility to injury and overall vocal health. The purpose of this article is to provide a broad-based review of current knowledge of the vocal fold epithelial barrier.

              The role of hydration in vocal fold physiology

              Increased vocal fold hydration is a popular target in the prevention and management of voice disorders. Current intervention strategies focus on enhancing both systemic (internal) and superficial (surface) hydration. We review relevant bench and human research on the role of hydration in vocal fold physiology.
