Abstract

Background and Objectives : This study was performed to investigate the perceptual and aerodynamic characteristics and the relation between vocal efficiency and the severity of strained voice. of adductor spasmodic dysphonia. Materials and Methods : 13 female patients with adductor spasmodic dysphonia were examined and compared with 10 normal female control group. MPT, MFR, Psub, Sound Intensity, VE(vocal efficiency) were obtained using PAS(Phonatory Aerodynamic System). GRBA(S) scale was used for Perceptual evaluation. Results : Psub(subglottic pressure) of SD was significantly higher than normal group. MPT, MFR, Sound Intensity, VE were not significantly different between two groups. Correlation between VE and 'S'(strained) was not significant. Conclusion : The results of this study show that certain aerodynamic parameters(Psub) distinguish adductor spasmodic dysphonia from normal voice.
