目的
发声功能亢进与喉肌活动异常有关，被认为是原发性肌张力性发声障碍（pMTD）的近端原因。相对基频（RFF）被认为是发声机能亢进的客观声学指标。本研究检查了（a）RFF跟踪pMTD治疗后发声功能亢进变化的能力和（B）发声困难严重程度对RFF计算可行性的影响。
方法
RFF计算和发音困难的严重程度等级来自111名pMTD女性和20名健康对照者治疗前后的记录。分析了三个元音-无辅音-元音刺激。
结果
RFF发作斜率始终随组（pMTD vs.对照组）和时间（治疗前vs.治疗后）而变化。观察到RFF发作周期1与发声困难严重程度之间存在显著相关性。然而，在许多样本中，RFF无法计算，调整后的比值比显示，这些不可分析的数据与发音困难的严重程度，语音（元音-无辅音-元音）背景和组（pMTD与对照组）有关。
结论
RFF发作似乎对治疗前后疑似发声功能亢进的存在和程度敏感。大量不可分析的样本（尤其与pMTD组的发音困难严重程度相关）代表了一个重要的局限性。
Purpose
Vocal hyperfunction, related to abnormal laryngeal muscle activity, is considered the proximal cause of primary muscle tension dysphonia (pMTD). Relative fundamental frequency (RFF) has been proposed as an objective acoustic marker of vocal hyperfunction. This study examined (a) the ability of RFF to track changes in vocal hyperfunction after treatment for pMTD and (b) the influence of dysphonia severity, among other factors, on the feasibility of RFF computation.
Method
RFF calculations and dysphonia severity ratings were derived from pre- and posttreatment recordings from 111 women with pMTD and 20 healthy controls. Three vowel-voiceless consonant-vowel stimuli were analyzed.
Results
RFF onset slope consistently varied as a function of group (pMTD vs. controls) and time (pretherapy vs. posttherapy). Significant correlations between RFF onset cycle 1 and dysphonia severity were observed. However, in many samples, RFF could not be computed, and adjusted odds ratios revealed that these unanalyzable data were linked to dysphonia severity, phonetic (vowel-voiceless consonant-vowel) context, and group (pMTD vs. control).
Conclusions
RFF onset appears to be sensitive to the presence and degree of suspected vocal hyperfunction before and after therapy. The large number of unanalyzable samples (related especially to dysphonia severity in the pMTD group) represents an important limitation.
