Abstract

AIMS AND OBJECTIVES

Primary muscle tension dysphonia (pMTD) is a common cause of voice disorders and is treated by speech and language pathologists (SLPs). Some singing teachers specializing in the habilitation of the performance voice also have rehabilitation skills helping singers recover from illness. The aim of this pilot study was to assess the feasibility and acceptability of using a structured and well-characterized habilitation and rehabilitation pedagogic technique for singers, The Complete Vocal Technique (CVT), in the treatment of patients with speaking voice problems due to pMTD. The three study objectives were to: 1) assess the feasibility of recruiting and retaining participants in a CVT-VT program; 2) assess the feasibility of using CVT voice therapy (CVT-VT) to improve the voice and voice function; and 3) assess the acceptability of this approach to patients, the CVT practitioner (CVT-P), and the supervising SLP.

STUDY DESIGN

Preregistered, uncontrolled, prospective feasibility study.

METHODS

Patients with pMTD meeting the inclusion criteria in the 6-month trial period were offered up to six telehealth sessions of CVT-VT delivered by the CVT-P. Patients underwent a multidimensional assessment [Voice Handicap Index (VHI), attainment of goals for treatment, Vocal Tract Discomfort Scale (VTDS), acoustic/electroglottographic (EGG) measures of sustained vowels, Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) audio-perceptual evaluation, and maximum phonation time (MPT)] pretherapy and post therapy. Feasibility was assessed by meeting a priori recruitment targets and acceptability assessment framework.

RESULTS

Eleven participants completed the study protocol demonstrating recruitment feasibility. All multidimensional measures, except MPT, showed improvement, demonstrating feasibility of CVT-VT to improve the voice, voice function, vocal tract discomfort, and achievement of goals. All patients and the CVT-P rated the acceptability of therapy as either very satisfactory or satisfactory.

CONCLUSIONS

CVT-VT is a feasible and acceptable form of treatment and warrants further evaluation as an additional tool for voice therapy in patients with pMTD.

摘要

目的

原发性肌肉紧张性发声障碍（pMTD）是嗓音障碍的常见原因，由言语和语言病理学家（SLP）进行治疗。一些专门从事表演嗓音康复训练的歌唱教师也具备帮助歌手从疾病中恢复的康复技能。这项初步研究的目的是评估对歌手使用一种结构化且特征明确的康复训练教学技术——完整发声技术（CVT），来治疗因pMTD导致的嗓音问题患者的可行性和可接受性。三个研究目标分别为：1）评估在CVT - VT项目中招募和留住参与者的可行性；2）评估使用CVT嗓音治疗（CVT - VT）改善嗓音和嗓音功能的可行性；3）评估这种方法对患者、CVT从业者（CVT - P）以及监督的SLP的可接受性。

研究设计

预先注册的、非对照的前瞻性可行性研究。

方法

在6个月的试验期内，符合纳入标准的pMTD患者接受由CVT - P提供的最多6次CVT - VT远程医疗课程。患者在治疗前和治疗后接受多维评估[嗓音障碍指数（VHI）、治疗目标达成情况、声道不适量表（VTDS）、持续元音的声学/电子声门图（EGG）测量、嗓音的共识听觉 - 感知评估（CAPE - V）、最长发声时间（MPT）]。通过达到预先设定的招募目标和可接受性评估框架来评估可行性。
