描述患有老年性發聲障礙之高齡者的說話時呼吸運動學

// Characterizing the Speech Breathing Kinematics of Older Adults With Presbyphonia

研究針對35名79.8歲老年性聲音障礙者（presbyphonia），發現語音起始肺容積較低（%VC）、肺容積變動較小、語句較短且語速較快｜呼氣流速上升但吸氣流速顯著下降，於噪音中提高音量時部分指標回復｜作者建議在喉部介入外同步評估與治療說話呼吸，並以匹配對照進行後續研究。

// This study tested whether older adults with presbyphonia show different speech-breathing patterns than typical peers. Thirty-five adults (mean age 79.8) completed reading and monologue tasks in quiet and noise while inductive plethysmography and calibrated acoustics measured lung-volume and flow (primary outcome: lung volume at speech initiation, %VC). Compared with published norms, participants with presbyphonia began speech at lower lung volumes, had smaller lung-volume excursions, shorter utterances, faster speech, higher expiratory but much lower inspiratory flows, and these measures partially normalized when speaking louder in noise. The authors conclude altered respiratory kinematics are part of presbyphonia and recommend assessing and treating speech breathing alongside laryngeal-focused interventions, with future studies using well-matched controls.
