聲門下壓力與浸水深度：水阻管練習中決定發聲成效的關鍵因素

// Subglottic Pressure and Immersion Depth: Key Determinants of Voice Outcomes in Water Resistance Tube Exercise

40名成人（正常20、功能性嗓音20）於5種WRT浸深×3Psub（亞聲門下壓力）發聲，測EGG接觸比CQ、口腔壓與自評｜更深或較高Psub增CQ並使口腔壓不穩、改變感覺且降低發聲容易度；兩組效應相似，臨床應控管浸深與Psub以優化WRT。

// The study tested how water-resistance tube (WRT) immersion depth and subglottic pressure (Psub) affect oral pressure oscillations, glottal adduction, and perceived ease of phonation. Forty adults (20 with normal voice, 20 with functional dysphonia) phonated into a tube at five immersion depths and three Psub targets while oral pressure metrics, EGG contact quotient (CQ), and self-rated ease were recorded. Greater immersion depth and higher Psub increased CQ, increased instability of oral pressure oscillations (amplitude/frequency/jitter/shimmer), altered bubble/massage sensations, and reduced perceived ease, with similar effects in both groups. Controlling immersion depth and Psub is therefore important to optimize WRT therapy.
