| description | Introduction. Hyperkinetic (hyperfunctional) dysphonia is a common pathology.
The disorder is often found in vocal professionals faced with high vocal
requirements. Objective. The objective of this study was to evaluate the
effects of vocal therapy on voice condition characterized by hyperkinetic
dysphonia with prenodular lesions and soft nodules. Methods. The study
included 100 adult patients and 27 children aged 4-16 years with prenodular
lesions and soft nodules. A subjective acoustic analysis using the GIRBAS
scale was performed prior to and after vocal therapy. Twenty adult patients
and 10 children underwent objective acoustic analysis including several
acoustic parameters. Pathological vocal qualities (hoarse, harsh and breathy
voice) were also obtained by computer analysis. Results. The subjective
acoustic analysis revealed a significant (p<0.01) reduction in all dysphonia
parameters after vocal treatment in adults and children. After treatment, all
levels of dysphonia were lowered in 85% (85/100) of adult patients and 29%
(29/100) had a normal voice. Before vocal therapy 9 children had severe, 13
had moderate and 8 slight dysphonia. After vocal therapy only 1 child had
severe dysphonia, 7 had moderate, 10 had slight levels of dysphonia and 9
were without voice disorder. The objective acoustic analysis in adults
revealed a significant improvement (p≤0.025) in all dysphonia parameters
except SD F0 and jitter %. In children, the acoustic parameters SD F0, jitter
% and NNE (normal noise energy) were significantly improved (p=0.003-0.03).
Pathological voice qualities were also improved in adults and children
(p<0.05). Conclusion. Vocal therapy effectively improves the voice in
hyperkinetic dysphonia with prenodular lesions and soft nodules in both
adults and children, affecting diverse acoustic parameters. |
