This study was conducted to investigate the respiratory and aerodynamic function of adductor spasmodic dysphonia (ADSD) patients. Participants were (1) 18 females SD patients with non- Botulinum toxin injection (2) 14 females SD patients who had taken treatment of Botulinum toxin injection. (3) 14 age- and sex- matched normal female controls. Spirometer and phonatory function analyzer were used for respiratory muscle pressure (MIP: Maximum inspiratory pressure), MEP: Maximum expiratory pressure)& MPT(Maximum phonation time) and aerodynamic(F0:Fundamental frequency, intensity, MFR: Mean flow late, Psub: Subglottal pressure) measurement. The results were as follows: (1) Normal group was significantly higher in MIP, MEP, MPT than two SD groups (p < .05); (2) MPT was significantly lower in SD with non-Botulinum toxin injection group than SD with the treatment experience of Botulinum toxin injection (p < .05); (3) All aerodynamic parameters, F0, intensity, MFR, Psub, were not significantly different among three groups(p > .05).The reason of short MPT in ADSD may use lower respiratory pressure than normal group as strategy to decrease their tremulous voice quality. Moreover respiratory muscle pressure was lower than normal group regardless of botulinum toxin injection treatment.
