Objectives: High laryngeal position, pharyngeal constriction, laryngeal and neck tension, excessive supraglottic compression, and vocal fold closure are common characteristics associated with hyperfunctional dysphonia. The purpose of this study was to investigate the effects of voice therapy consisting of laryngeal massage and semi-occluded vocal tract exercises (SOVTE) in patients with hyperfunctional dysphonia and following voice therapy adherence.
Methods: Twenty-eight patients with hyperfunctional voice disorders diagnosed with muscle tension dysphonia, vocal nodules, and vocal polyp were treated with voice therapy once using laryngeal massage and SOVTE: lip trills, humming, bilabial fricative [b:], straw phonation. They completed acoustic and auditory?perceptual assessment before and after voice therapy.
Results: Significant immediate effects were observed in STD (standard deviation of F0), Jitter, Shimmer, NHR (noise to harmonic ratio), vAm (peak to peak amplitude variation), vF0 (fundamental frequency variation), ATRI (Amplitude Tremor Intensity Index), FTRI (F0 Tremor Intensity Index), PPQ (pitch perturbation quotient), APQ (amplitude perturbation quotient), DSH (degree of sub-harmonic), VTI (Voice Turbulence Index), DUV (degree of voiceless) and ‘G’, ’R’, ‘B’ in the GRBAS scale and most of the patients continued with voice therapy.
Conclusion: Laryngeal massage and SOVTE may provide immediate advantages in hyperfunctional dysphonia and have a positive effect on voice therapy adherence.
