Summary
This study shows that an eclectic voice therapy approach effectively improved vocal fold function and reduced voice problems in individuals with hyperfunctional voice disorder (HFVD). Patients experienced less dysphonia and self-perceived handicap after treatment.
Area of Science:
- Speech-Language Pathology
- Otolaryngology
- Voice Science
Background:
- Hyperfunctional voice disorder (HFVD) is a complex condition with multiple contributing factors.
- Eclectic voice therapy, combining various approaches, is hypothesized to enhance voice efficiency in HFVD patients.
- Limited research exists on the efficacy of eclectic voice therapy for HFVD using comprehensive outcome measures.
Purpose of the Study:
- To investigate the effectiveness of an eclectic voice therapy program for treating hyperfunctional voice disorder (HFVD).
- To evaluate changes in laryngeal function and voice quality using multidimensional outcome measures.
- To assess the impact of therapy on self-perceived voice handicap.
Main Methods:
- Ten individuals with HFVD participated in a 15-session Comprehensive Voice Habilitation Program (CVHP) over three weeks.
- Laryngeal function was assessed via stroboscopy at baseline and post-therapy.
- Perceptual voice analysis, Acoustic Voice Quality Index (AVQI), and Voice Handicap Index in Kannada (VHI-K) were measured pre-therapy, post-therapy, and at follow-up.
Main Results:
- Stroboscopy indicated improved vocal fold movement and reduced ventricular hyperadduction.
- Perceptual ratings and AVQI scores showed a decrease in dysphonia severity post-therapy and at follow-up.
- VHI-K scores significantly decreased, indicating reduced self-perceived handicap.
Conclusions:
- The study provides preliminary evidence supporting the efficacy of eclectic voice therapy for HFVD.
- Significant improvements were observed across objective and subjective voice outcome measures.
- Eclectic voice therapy shows promise as a treatment for hyperfunctional voice disorder.
