Abstract | The study is an initial attempt to investigate the effects of whole body vibration (WBV) on
perceived vocal condition, phonatory function and physiological changes in vocal fatigue
participants. Thirty participants aged between 19 to 25 years old with healthy voice were
recruited and performed in a continuous singing task to induce vocal fatigue. They were
randomly assigned to one intervention group: a WBV group that received 10 minutes of
whole body vibration with individualized vibrational frequencies, and a control group that
had vocal rest. Changes in perceptual ratings on the ease of soft phonation and vocal fatigue
symptoms, maximum frequency, blood pressure and blood oxygen saturation level were
measured and compared across intervention groups. Results showed that WBV intervention
promoted significantly greater improvement in perceived vocal condition than the control
group, evidenced by a significant larger decrease in perceptual ratings on the ease of soft
phonation (p < .01) and vocal fatigue symptoms (p < .001). However, no treatment effects
were found for maximum frequency, blood pressure and blood oxygen level. This study
suggests the potential use of WBV in reducing perception of vocal fatigue.
