摘要

目的:肌肉紧张性发音障碍(MTD)是一种功能性嗓音疾病,会导致不规则和不平衡的喉和咽旁肌肉激活。我们的研究旨在检查 MTD 患者的声学特征,并揭示性别差异:本研究回顾性审查了 2015 年至 2022 年间在一家三级甲等参考医院喉科门诊评估期间被诊断为 MTD 的患者档案中的声学检查结果。在延长元音发音分析中,评估的参数包括基频(F0)、抖动、闪烁、噪声-谐波-比率和软发音指数;在计数任务分析中,评估的参数包括强度、频率和半音。研究还考察了长时间元音发音和计数任务中声学测量结果的性别差异:研究共纳入了 80 名被诊断为 MTD 的患者。虽然在元音/a/发音的声学分析中,所有参数都有所增加,但只有在 F0 和抖动参数上,男女之间的差异具有统计学意义(P≤0.05)。在计数任务分析中,女性的平均和最小 F0 参数明显高于男性(p=0.000)。平均分贝水平有所下降,尤其是在数数任务中,但强度参数的结果在性别间没有明显差异(p>0.05):结论:确定了 MTD 患者的声学语音分析参数值。这些声学参数可为临床医生评估嗓音和确定 MTD 患者的嗓音治疗目标提供指导。

Investigation of Acoustic Voice Characteristics of Individuals Diagnosed with Muscle Tension Dysphonia.

Objective: Muscle tension dysphonia (MTD) is a functional voice condition that causes irregular and imbalanced laryngeal and paralaryngeal muscle activation. Our study aimed to examine the acoustic characteristics of patients with MTD and reveal the differences between genders.

Methods: The study retrospectively reviewed the acoustic examination findings from the files of patients diagnosed with MTD during evaluations in the laryngology outpatient clinic at a tertiary reference hospital between 2015 and 2022. The parameters assessed in prolonged vowel phonation analysis were fundamental frequency (F0), jitter, shimmer, noise-to-harmonic-to-ratio, and soft phonation index; in the counting task analysis, they were intensity, frequency, and semitone. Gender differences in acoustic measurements obtained during prolonged vowel phonation and counting tasks were also examined.

Results: The study included 80 individuals diagnosed with MTD. Although all parameters in the acoustic analysis of/a/ phonation were increased, differences were statistically significant only in the F0 and jitter parameters between females and males (p≤0.05). In the analysis of the counting task, the mean and minimum F0 parameters were significantly higher in females than in males (p=0.000). The mean dB level was decreased, particularly in the counting task, but the results for the intensity parameter did not differ significantly between genders (p>0.05).

Conclusion: The values in the acoustic voice analysis parameters of patients with MTD were determined. These acoustic parameters are thought to guide the clinician in evaluating voice and determining voice therapy goals for MTD patients.
