Summary
Objective
To map the execution of resonance tubes phonation immersed in water exercise in adults
with healthy or altered voices.
Methods
This study was a scoping review. An electronic search was performed using the following
databases: MEDLINE, LILACS, SCOPUS, Web of Science, EMBASE, Cochrane Library, gray
literature, and a manual search. A blinded review was performed by two authors to
determine the selection and extraction procedures. Studies with adult participants
with dysphonic or healthy voices who underwent intervention with phonation in a resonance
tube immersed in water in the context of the vocal clinic, with an experimental intervention,
quasi-experimental, or before and after the intervention were included. Data from
the publication, sample, execution, and results obtained from the exercises were extracted
by two blinded reviewers. Disagreements were resolved through consensus. The analysis
was performed quantitatively.
Results
A total of 44 publications were analyzed. Among these, Brazilian studies were the
most frequent, with a publication peak in 2020. The characterization of the sample
was variable, with a higher frequency of participants of both sexes who were not voice
professionals. The most frequent studies were before and after exercise with a resonance
tube immersed in water, in one session, with an exercise execution time of 3 minutes;
in cases of more than one series of executions, the 30-sseconds rest time was more
frequent. The most used resonance tube was a flexible silicone tube, with a wall thickness
of 0.1 mm, immersion container in a 500-, 510-, or 600-mL bottle, 2/3 filled with
water, and the resonance tube immersed 2 cm from the water surface. The most used
phonatory task was flow phonation with rounded lips similar to the articulation of
the vowel /u/. Acoustic analysis and vocal self-assessment are the most commonly used
outcome measures. The best results were obtained in the self-assessment.
Conclusion
There is significant variability in the information on the execution of resonance
tubes phonation immersed in water exercise influenced by vocal diagnosis and experience
with previous vocal training. Studies on the effects of this exercise have been concentrated
over the last decade and are of the vocal training and therapy. Acoustic and self-assessment
measures were used to verify the results, with self-assessment being the outcome that
most frequently indicated positive results.
