There have been various methods devised to monitor vocal fold vibration. Stroboscopy provides clinically-celevant information concerning pathology of the vocal folds. However, slow motion observation is based on the regularity of the vibration, and this ignores the role of irregularity of the vocal fold vibration in pathological cases. In order to know more about the nature of the vocal fold vibratory pattern, it is essential to monitor the vibration on a cycle by cycle basis. We analysed vocal fold vibrations of 22 pathological larynges using a computer-assisted high-speed digital imaging technique. Observed items included symmetry, regularity, phase difference, glottal closure, amplitude, mucosal wave and periodicity difference. Vibratory patterns were classified by location of lesion, severity of disease, expiratory pressure and laryngeal modulation. Analyses of pathological vocal fold vibrations using high-speed digital imaging techniques are providing the theoretical support for voice therapy and elucidating the causes of hoarseness.
已经设计出了各种监测声带振动的方法。频闪喉镜检查可提供有关声带病理学的临床相关信息。然而，慢动作观察是基于振动的规律性，而这忽略了声带振动不规则性在病理情况下的作用。为了更深入了解声带振动模式的本质，逐周期监测振动至关重要。我们使用计算机辅助高速数字成像技术分析了22例病理性喉部的声带振动。观察项目包括对称性、规律性、相位差、声门闭合、振幅、黏膜波和周期性差异。振动模式根据病变位置、疾病严重程度、呼气压力和喉部调节进行分类。使用高速数字成像技术对病理性声带振动进行分析，为嗓音治疗提供了理论支持，并阐明了声音嘶哑的原因。
