帕金森氏症喉部運動控制的運動學特徵

// Kinematic Features of Laryngeal Motor Control in Parkinson's Disease

本研究利用高速內視鏡檢視帕金森氏症患者的喉部運動控制｜透過重複發聲與不同用力程度，分析聲帶運動的時空變異指數（STI）與不對稱指數（AI）｜結果顯示帕金森氏症患者STI顯著較高，代表運動控制變異加大，且用力程度無顯著影響｜STI指標能有效區分患者與正常對照的喉部運動差異，具臨床診斷潛力。

// This study examined laryngeal motor control in people with Parkinson's disease (PD) using high-speed videoendoscopy during repeated vocalizations at varying effort levels. Two kinematic measures, spatiotemporal index (STI) and asymmetry index (AI), were assessed to evaluate vocal fold movement variability and coordination. Results showed that people with PD had significantly higher STI, indicating greater motor control variability, while vocal effort level did not affect these measures. The STI effectively distinguished laryngeal motor control differences between PD patients and controls.
