目的目前，尚无临床上可行的针对喉内收肌张力障碍（LD）体征的客观措施，阻碍了有效的诊断和治疗。该项目旨在建立并行有效性的一个新的自动化的声学结果的措施，旨在具体到喉内收肌张力障碍（AdLD）：频谱聚合的高通基频轮廓（SAHFO）。MethodTwenty扬声器AdLD阅读有声音素加载（症状更明显）和无音音素加载（症状更少）的句子。LD不连续性（定义为发声中断，频率偏移和吱吱声），喉痉挛的声学分支，手动识别。检查focorour的频率内容作为时间的函数，并将1000 Hz以上的内容相加以自动计算SAHfo。多元线性回归分析应用于SAHfo based LD不连续性和句子类型（有声或无声音素加载）。LD的不连续性和句子类型与SAHfo.ConclusionResults的统计学相关，这项研究提供了证据的同时效度。SAHfo是AdLD声学体征的自动结果测量，可用于跟踪治疗进展。
ObjectiveCurrently, no clinically feasible objective measures exist that are specific to the signs of adductor laryngeal dystonia (LD), deterring effective diagnosis and treatment. This project sought to establish concurrent validity of a new automated acoustic outcome measure, designed to be specific to adductor laryngeal dystonia (AdLD): the spectral aggregate of the high-passed fundamental frequency contour (SAHfo).MethodTwenty speakers with AdLD read voiced phoneme-loaded (more symptomatic) and voiceless phoneme-loaded (less symptomatic) sentences. LD discontinuities (defined as phonatory breaks, frequency shifts, and creak), the acoustic ramifications of laryngeal spasms, were manually identified. The frequency content of thefocontour was examined as a function of time, and content above 1000 Hz was summed to automatically calculate SAHfo. Multiple linear regression analysis was applied to SAHfobased on LD discontinuities and sentence type (voiced or voiceless phoneme-loaded).ResultsThe regression model accounted for 41.1% of the variance in SAHfo. Both the LD discontinuities and sentence type were statistically related to SAHfo.ConclusionResults of this study provide evidence of concurrent validity. SAHfois an automatic outcome measure specific to acoustic signs of AdLD that may be useful to track treatment progress.
