遠距共鳴嗓音治療對肌肉緊張性發聲障礙之治療成效
Effectiveness of Resonant Voice Therapy Delivered via Telepractice on Muscle Tension Dysphonia
摘要
背景：肌肉緊張性發聲障礙（muscle tension dysphonia, MTD）是一種常見的嗓音障礙類型，其主要特徵為喉內肌以及喉外肌的肌肉張力過大，進而導致聲音沙啞、嗓音緊困、喉部疲勞、喉部疼痛等症狀。目前學界及臨床實務上已有數種治療手法經證實可有效治療MTD個案，然而以共鳴嗓音治療（resonant voice therapy, RVT）介入MTD個案的相關文獻仍相對稀缺。RVT為生理性嗓音治療的一種，此種治療之目的為讓個案使用正確的前置共鳴位置，進而放鬆喉部並減低喉部的發聲負荷，來達到改善嗓音的成效。此外，因應現今科技快速的發展以及新型冠狀病毒（COVID-19）疫情影響，遠距醫療儼然成為近年的新興醫學趨勢，而透過視訊針對MTD個案進行遠距治療之相關研究亦相當匱乏。綜合上述研究問題，本研究旨在探討遠距RVT對MTD個案之治療成效。方法：本研究共收案7位經診斷為原發性MTD之個案。個案皆完成1週1次共8次的RVT，且治療乃透過遠距治療模式進行。每位個案皆接受前後測之聽知覺、聲學、氣動學以及自評嗓音生活品質之評估，分析個案治療後進步情形。結果：統計分析結果顯示，個案於完成8次遠距RVT治療後，其聽知覺、聲學以及自評嗓音生活品質評估結果出現顯著進步。結論：此結果初步顯示遠距RVT可有效治療MTD個案。

BACKGROUND: Muscle tension dysphonia (MTD) is a voice disorder commonly seen among patients with voice-related problems. The main symptoms of MTD are hoarseness, strain, fatigue, and throat pain due to high muscle tension in the extrinsic and intrinsic muscles of the larynx. Several voice therapy methods have been suggested to be effective in treating MTD. Yet, up-to-date, only a few articles focus on the resonant voice therapy (RVT). RVT is a type of physiological voice therapy which aims to correct resonance in order to relax the larynx and reduce loadings of phonation. Besides, due to the advancement of technology and the outbreak of COVID-19, telehealth has become a new trend. However, evidence on the effectiveness of treating MTD patients via telepractice is still lacking. Thus, this study aims to investigate whether RVT delivered via telepractice is effective in treating patients with MTD. METHODS: Seven participants diagnosed with MTD were included in this study. All participants received eight sessions of RVT, provided once a week, via telepractice. Auditory-perceptual ratings, acoustic and aerodynamic measurements, and self-rated voice-related quality of life questionnaire were analyzed and compared pre- and post-treatment. RESULTS: The results revealed that participants' auditory-perceptual ratings, acoustic measurements, and self-assessed voice-related quality of life have improved significantly post treatment. CONCLUSIONS: The preliminary results provide support that RVT delivered via telepractice is effective in treating patients with MTD.
