Abstract
GARCIA-REAL, Teresa Juana; DIAZ-ROMAN, Tomás Miguel and LOSADA-PUENTE, Luisa. Combined hydration and effects on the vocal health in speech language pathology students. Rev Asoc Esp Espec Med Trab [online]. 2023, vol.32, n.2, pp.99-109. Epub Oct 30, 2023. ISSN 3020-1160.
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.
