Abstract
Objective
to verify the effect after short-term intensive therapy with the Finger Kazoo technique
on vocal and aerodynamic measures of dysphonic female teachers.
Method
blind randomized clinical trial. Fifteen female teachers without structural disorders
of vocal folds and nine with vocal nodules participated in the study groups. Yet,
nine female teachers without structural disorders and eight with vocal nodules in
the control groups. The following variables were measured pre and post-therapy: minimum
and maximum fundamental frequency: forced vital capacity; simple phonic coefficient;
compound phonic coefficient; ratio between maximum phonation time of /a/ and expected
maximum phonation time.
Results
no statistical significance was observed in the intra and intergroup analyses in any
of the measures.
Conclusion
in this group of female teachers, it was not possible to show a positive effect of
short-term and intensive therapy with the Finger Kazoo technique on the vocal measures
of minimum and maximum fundamental frequency, forced vital capacity, simple phonic
coefficient, compound phonic coefficient, and the relationship between maximum phonation
time of /a/ and expected maximum phonation time.
