本研究的目的是确定适当的声学和结果的措施，用于评估的方法，喉手动治疗（LMT）用于治疗肌肉紧张性发声障碍（MTD）的患者。还研究了该技术的效果。该研究基于以下假设：喉在声道中的垂直位置会降低，声音质量会正常化，LMT后任何声道不适（VTD）都会减少。这是一项小型、前瞻性、重复测量的试点研究，其中研究团队的每个成员对研究的所有其他阶段都是“盲态”的，在此期间，所有数据都是匿名的，直到数据分析的最后阶段。10例MTD受试者完成了结局测量，并在LMT前即刻、LMT后即刻和LMT后1周提供了录音。Kay CSL 4150用于信号采集和一些声学测量。使用Praat完成光谱评价。一个新的知觉，自我评价量表，VTD规模，和一个新的形式，用于临床触诊评估，为研究开发。在连接语音的相对平均扰动显着减少后LMT，表明减少异常的发声功能。LMT后VTD的严重程度和频率降低。这项初步研究显示了积极的证据，LMT作为一种治疗方法，在治疗功能亢进的声音障碍。它的影响被证明是可测量的声学分析和VTD规模。
The objectives of this study were to determine appropriate acoustic and outcome measures for the evaluation of a method of laryngeal manual therapy (LMT) used in the treatment of patients with muscle tension dysphonia (MTD). The effects of this technique were also investigated. The study was based on the hypotheses that the Vertical position of the larynx in the vocal tract would lower, that the quality of the voice would normalize, and that a reduction in any vocal tract discomfort (VTD) would occur after LMT. This was a small, prospective, repeated measures pilot study in which each member of the research team was "blinded" to all other stages of the study and during which all data were anonymized until the final stage of data analysis. Ten subjects presenting with MTD completed outcome measures and provided audiorecordings immediately before, immediately after, and I week after LMT. The Kay CSL 4150 was used for signal acquisition and for some acoustic measurements. Spectrographic evaluation was accomplished with Praat. A new perceptual, self-rating scale, the VTD scale, and a new proforma for use by the clinician for palpatory evaluation, were developed for the study. Relative average perturbation during connected speech was significantly reduced after LMT, indicating a reduction in abnormal vocal function. The severity and frequency of VTD was shown to have reduced after LMT. This pilot study showed positive evidence for LMT as a method of therapy in the treatment of hyperfunctional voice disorders. Its effects were shown to be measurable with both acoustical analysis and the VTD scale.
