摘要

目的：基于高速视频内窥镜的数字视频肌动图可以评估治疗技术和嗓音训练（如 LaxVox 技术）对声带振动的影响。本研究调查了 LaxVox 技术对通过高速视频内窥镜获得的数字视频肌电图参数的直接影响：研究设计：对有嗓音不适的成人进行受试者内部对比实验研究：方法：使用图像处理软件分析视频并获得数字视频嗓音造影参数。使用类内相关系数确定分析参数的评分者内部可靠性。在性别分析中，使用配对 t 检验和 Wilcoxon 符号秩检验比较 LaxVox 技术前后的数字视频肌成像参数。显著性水平设定为 5%：共分析了来自 15 名女性和 10 名男性的 25 张喉部图像。通过数字视频肌电图分析，女性在使用 LaxVox 技术后，声门后部的平均声带开度立即减小。相比之下，与使用 LaxVox 技术前的数值相比，嗓音不适的男性和女性的其他参数均无明显变化：结论：数字视频肌动图分析显示，LaxVox 技术降低了嗓音不适女性声门后部的平均声带开度。

Analysis of the Immediate Effects of the LaxVox Technique on Digital Videokymography Parameters in Adults With Voice Complaints

Objectives

Digital videokymography based on high-speed videoendoscopy enables the evaluation of therapeutic techniques and voice training, such as the LaxVox technique, on vocal fold vibrations. This study investigated the immediate effects of the LaxVox technique on digital videokymographic parameters obtained through high-speed videolaryngoscopy in adults with voice complaints.

Study Design

An experimental intrasubject comparative study of adults with voice complaints was conducted.

Methods

Image processing software was used to analyze the videos and obtain digital videokymography parameters. The intraclass correlation coefficient was used to determine the intra-rater reliability of the analyzed parameters. The paired t test and Wilcoxon signed-rank test were used to compare digital videokymography parameters before and after the LaxVox technique, in sex-specific analyses. The significance level was set at 5%.

Results

In total, 25 laryngeal images from 15 women and 10 men were analyzed. On digital videokymography analysis, the mean vocal fold opening in the posterior glottal region was decreased immediately after using the LaxVox technique in women. In contrast, no significant changes were found in other parameters compared to pre LaxVox technique values in both men and women with voice complaints.

Conclusion

Digital videokymography analysis revealed that the LaxVox technique reduces the mean vocal fold opening in the posterior glottal region of women with voice complaints.
