Abstract

OBJECTIVES

Laryngeal and voice findings of adductor spasmodic dysphonia (AdSD) and muscle tension dysphonia (MTD) are similar, and it is difficult to distinguish between both disorders. The purpose of this study is to ascertain the effect of voice therapy on MTD and AdSD and clarify their difference.

METHODS

A total of 49 patients, including 22 patients with MTD (MTD group) and 27 patients with AdSD (SD group), were included in the study. The MTD scores were evaluated, and aerodynamic analysis (maximum phonation time [MPT], mean airflow rate [MFR], highest pitch, lowest pitch, and pitch range), perceptual evaluation (Strangulation, Interruption, and Tremor), acoustic analysis (PPQ, APQ, NHR, and DVB), and subjective assessment (voice handicap index-10 [VHI-10]) were performed before and after voice therapy.

RESULTS

The MTD score, highest pitch, pitch range, strangulation, PPQ, APQ, NHR, and VHI-10 showed significant improvement after treatment in the MTD groups. On the other hand, the effect of voice treatment on AdSD was poor despite the improvement in the MTD score.

CONCLUSIONS

This study could serve as a basis for conducting prospective studies to verify the effects of voice therapy on MTD and AdSD.

摘要

目的

痉挛性发声障碍（AdSD）和紧张性发声障碍（MTD）的喉部和嗓音表现相似，两者难以区分。本研究旨在确定嗓音治疗对 MTD 和 AdSD 的效果，并阐明两者的差异。

方法

共纳入 49 例患者，其中 22 例为 MTD（MTD 组），27 例为 AdSD（SD 组）。评估 MTD 评分，并进行空气动力学分析（最长发声时间[MPT]、平均气流率[MFR]、最高音、最低音和音域范围）、感知评估（Strangulation、Interruption 和 Tremor）、声学分析（PPQ、APQ、NHR 和 DVB）和主观评估（嗓音障碍指数-10[VHI-10]）。
