Abstract

Background

Disorders of voice can limit an individual's participation and impair social interaction, thus affecting overall quality of life. Perceptual and objective evaluations can provide the clinician with detailed information regarding voice disorders.

Methods

This study comprised 40 subjects aged 34–46 years, 20 of whom (10 male, 10 female) had unilateral vocal fold palsy. Data were obtained for all participants from: the Voice Handicap Index, the grade, roughness, breathiness, asthenia and strain (‘GRBAS’) scale, acoustic voice analysis, electroglottography, and voice range profiles.

Results

The voice evaluations revealed statistically significant (p < 0.05) differences between the controls and study group, both in males and females, pre- and post-therapy.

Conclusion

Despite the normalisation of vocal parameters, acoustic, perceptual and self-rated assessments revealed statistically significant differences after therapy. Hence, acoustic measures, namely electroglottographic perturbation, and voice frequency and intensity range, are recommended prior to termination of therapy.
