Voice therapy can improve the vocal quality of elderly patients with voice problems, but little is known about what happens physiologically. The purpose of the present study was to determine the effect of the management program known as Vocal Function Exercises (VFEs) on vocal aerodynamics and perceptual quality of voice. The effect of subject physical fitness level on change in VFE time was also considered. There were 24 subjects (19 experimental, 5 control) ages 60-78. The experimental group was subdivided into 3 fitness groups: Sedentary, Active, and Fit. The experimental group performed VFEs twice a day for 12 weeks, while the control group performed them once a week for 12 weeks. Aerodynamic measures of glottal airflow were collected at comfortable, high, and low pitches both before and after the 12-week exercise program. Statistical analysis revealed the Fit and Active subjects did not reach a plateau on the VFEs more quickly than the Sedentary subjects. The Sedentary group did not demonstrate a greater magnitude of change than either the Active or Fit group. For vocal aerodynamics, significant differences occurred between the experimental and control groups for selected measures. A logistic regression analysis revealed minimum flow and subglottal pressure (Psub) to be most sensitive to the effects of the VFEs. Perceptual analysis revealed that those subjects rated the most dysphonic improved their vocal quality, though the extent of change was limited due to the number of subjects with normal/mildly dysphonic voices prior to the exercise program. Interpretation of the aerodynamic results indicated that as a result of performing VFEs, greater vocal fold closure was achieved with a concomitant increase in Psub. Trends gleaned from the nonsignificant results in the aerodynamic measures supported this, particularly because there was no concurrent increase in intensity. Improvement in the VFE times also mirrored the improvement in vocal fold closure. The magnitude of change in the aerodynamic measures between the experimental and control groups might have been greater had the exercises been performed with greater intensity. Greater improvement in perceptual quality could be expected with a more dysphonic group of subjects.
