姿勢、黏度與頸圍對吞嚥聲學之影響：混合效應分析

// Influence of Posture, Viscosity, and Neck Circumference on Swallowing Acoustics: A Mixed-Effects Analysis

本研究探討頭頸姿勢、吞嚥物稠度及頸圍對吞嚥聲音持續時間與聲音強度的影響｜結果顯示，下巴內收姿勢提高平均聲強，且聲強隨吞嚥物稠度變化，頸圍則與聲強呈負相關｜吞嚥聲持續時間受姿勢影響有限，強調解讀未校準聲學數據須考慮個人體態與任務條件。

// This study investigated how head-neck posture, bolus viscosity, and neck circumference affect swallowing sound duration and mean acoustic intensity recorded via a neck-mounted microphone in healthy adults. Using linear mixed-effects models, researchers found that mean acoustic intensity was higher in the chin-tuck posture and varied with bolus viscosity, with neck circumference negatively impacting intensity. Swallowing sound duration showed minimal posture-related changes. The findings suggest that anatomical factors and task conditions must be considered when interpreting uncalibrated acoustic swallowing measures.
