Autopercepção vocal de acordo com a dose do exercício com tubo flexível imerso profundamente na água em indivíduos com doença de Parkinson

Abstract

Objective: To investigate the effect of exercise dose with a flexible resonance tube immersed deeply in water on the vocal self-perception of individuals with Parkinson's disease. Methods: This is a longitudinal, clinical, uncontrolled study. Thirty individuals over the age of 18 participated in the research. The exercise was performed with a flexible tube deeply immersed in water at five different times: pre-exercise, after one, three, five and seven minutes of exercise. At each moment, participants responded to the “perceived vocal comfort and quality scale” and the Borg CR10 scale of perceived vocal effort translated and adapted to Brazilian Portuguese. In the first, composed of two 100mm scales, participants evaluated vocal comfort as being easier or more difficult to produce the voice, and in the other scale, they self-assessed vocal quality varying between “dirtier” or “cleaner”. On the Borg scale, participants listed the number corresponding to the intensity of vocal effort exerted after completing the task in the requested minutes. The selected vocal effort values ​​were marked using the previous minutes as a reference. A descriptive analysis of the data was carried out for all variables studied. And inferential analysis using the ANOVA test, Tukey post-hoc, considering a significance level of 5%. Results: There was a difference in self-perception of vocal comfort between the moments before and after one minute of exercise; between pre and post three minutes; and between pre and post seven minutes. There was a difference in self-perception of vocal quality between before and after three minutes of performing the exercise; and between pre and after seven minutes. Conclusion: The exercise dose interferes with self-perception of comfort and vocal quality, however, in relation to vocal effort, no significant differences were identified.
