对于评估发声障碍时声门上压迫，声门上结构覆盖声带的分类评定量表是目前的标准。与没有声门上活动相比，量化声门上结构位置的变化将是区分语音障碍组和语音障碍组内部的更好方法。本研究建立了一种定量分析声门上静态活动和声门上动态活动时假声带（FVF）运动程度的方法。12名对照参与者和12名患有嗓音障碍的个体（6名主诉发声疲劳，6名声带小结）入组研究。这些人参加了经鼻纤维喉镜检查，其中各种语音任务被记录。选择单帧图像来代表每个语音任务的最小和最大声门上压缩的位置。两个人使用分类评级量表对这些单帧图像进行评级。另外两个人测量了前后（A-P）距离，声带长度和声带面积。A-P和FVF压缩来自这三个措施。法官之间的评级和法官之间和内部的措施证明了可靠性。标准化静态声门上压迫测量的显著差异对应于评定量表类别。标准化动态声门上压迫测量的显著差异对应于最小和最大压迫之间类别评级的差异。使用标准化的测量方法，嗓音障碍组表现出比对照组参与者显著更大的静态A-P压缩（t检验，p <0.03）。这些结果表明，静态声门上活动可能是诊断的声音障碍。两组之间的标准化动态FVF压缩率无显著差异。这支持了先前的假设，即动态声门上活动作为一个发音功能在喉的水平，是语言/音位系统的一部分，而不是喉功能紊乱的证据。
For estimating supraglottic compression in disordered voice production, categorical rating scales of true vocal fold coverage by supraglottic structures are the current standard. Quantification of change in the position of supraglottic structures compared to no supraglottic activity would be a better method for distinguishing between and within voice-disordered groups. This study developed a method for quantifying static supraglottic activity and extent of false vocal fold (FVF) motion during dynamic supraglottic activity. Twelve control participants and 12 individuals with voice disorders (6 with complaints of vocal fatigue and 6 with vocal fold nodules) were enrolled in the study. These individuals participated in a transnasal fiberoptic laryngeal examination in which various speech tasks were recorded. Single-frame images were selected to represent the positions of minimum and maximum supraglottic compression for each speech task. Two individuals rated these single-frame images using a categorical rating scale. Two other individuals measured the anterior-to-posterior (A-P) distance, vocal fold length, and vocal fold area. A-P and FVF compression were derived from these three measures. Reliability was demonstrated between judges for the ratings and between and within judges for the measures. Significant differences in normalized static supraglottic compression measures corresponded to the rating scale categories. Significant differences in normalized dynamic supraglottic compression measures corresponded to the differences in category ratings between minimum and maximum compression. Using the normalized measures, the voice-disordered groups demonstrated significantly greater static A-P compression (t test, p < .03) than did the control participants. These results suggest that static supraglottic activity may be diagnostic of voice disorder. Normalized dynamic FVF compression ratios were not significantly different between groups. This supports a previous hypothesis that dynamic supraglottic activity serves as an articulatory function at the level of the larynx and is part of the linguistic/phonemic system, rather than evidence of disordered laryngeal function.
