聽覺-體感對初級肌肉緊張性發聲困難聲音運動控制的影響

// Auditory-Somatosensory Influences on Vocal Motor Control in Primary Muscle Tension Dysphonia

本研究探討聽覺與本體感覺反饋對原發性肌肉緊張性發聲障礙（pMTD）患者的語音運動控制影響｜透過改變聽覺反饋與利多卡因霧化減弱本體感覺，發現pMTD患者適應能力較差且語音變異度較高｜減少本體感覺輸入反而改善語音適應，顯示異常的本體感覺處理與語音不穩定相關，且調控感覺反饋具治療潛力。

// This study investigated how auditory and somatosensory feedback affect vocal motor control in people with primary muscle tension dysphonia (pMTD) versus controls. Using altered auditory feedback and somatosensory disruption via nebulized lidocaine, the researchers measured vocal adaptation across different phases. They found that unlike controls, individuals with pMTD showed impaired adaptation and greater variability, but reducing somatosensory input improved their vocal adaptation. These results suggest that abnormal somatosensory processing contributes to vocal instability in pMTD and that targeting sensory feedback may have therapeutic potential.
