The This study aimed to evaluate the effects of the voice therapy we operated to the patients with age-related dysphonia. Thirty four participants who were diagnosed as age-related dysphonia in laryngoscopic finding from January, 2009 to December, 2009 completed the study. The participants were aged from 60 to 82 years old with a mean age of 70.6. All participants had received the abdominal breath technique, SKHPIP with laughter, and basic vocal training with description of their problem, the length of which ranged from four sessions to twelve sessions. We executed the videostroboscopy to compare the aspect of voicing change and the perceptual assessment, voice range profile, acoustic and aerodynamic measures to identify change of voice. Participants had glottal gap due to incomplete glottic closure during voicing on the pretest. After they took the voice therapy, the glottic gap became narrow and rough and breathy voice was reduced. There were significant difference in acoustic and aerodynamic measures. Jitter, Shimmer, MFR were reduced and MPT, Psub were increased(p＜.05). Participants" pitch range and intensity range were increased on the posttest performance after taking voice therapy. Especially, most of them were showed that pitch range was increased significantly in high frequency area. The results of this investigation indicate that the voice therapy using abdominal breath, SKHPIP, and exercise together is effective for the patients who have age-related dysphonia to improve their voice quality. We recommend to apply this technique to functional voice disorders who are showed glottal gap.
