Pressure, flow and glott al areawaveform profi le changes during phonati on using the Acapella Choice® device

Popis výsledku v původním jazyce

Vibratory positive expiratory pressure devices (PEP) are now considered a suitable resource for voice therapy. PEP devices produce large low frequency intraoral pressure modulations in the vocal tract that influences glottal behaviour. In this study, the impact of phonation into an Acapella Choice device (a type of PEP) on glottal behaviour was assessed. Phonation was produced by 2 males and 1 female participant whilst audio, EGG, pressure, flow and high-speed videoendoscopic data were collected. The results showed a systematic effect on glottal behaviour with changes in pressure caused by the Acapella device. When Acapella pressure was maximum, vocal fold vibration was hindered (lower: EGG amplitude, airflow, contact quotient (CQ), fundamental frequency (fo) and glottal area (GA)) as Acapella pressure reduced the opposite trend was observed. This systematic change in the supraglottic pressure modulates the behaviour of the vocal folds between what seems to be hindered and aided vibration. This behaviour confirms a mechanistic impact of the Acapella device on the phonatory apparatus that can be used for specific voice therapy purposes.
