由于人口老龄化，吞咽困难患者的数量迅速增加。因此，客观评价吞咽功能的重要性越来越受到重视。视频透视和视频内窥镜检查是吞咽困难的标准临床检查，但这些技术不适合日常使用，因为它们的侵入性。在这里，我们的目标是开发一种新的，非侵入性的方法来测量吞咽功能使用运动跟踪系统，Kinect v2传感器。吞咽功能正常的5名男性和5名女性参与了本研究。我们定义了三个与口腔相关的参数和两个与喉部相关的参数，并记录了吞咽开始前2.5秒至吞咽开始后2.5秒的数据。吞咽前观察口腔相关参数的变化，并在吞咽时达到峰值。与此相反，喉相关参数显示吞咽前变化不大，吞咽后立即达到峰值。这个简单的吞咽跟踪系统（SSTS）成功地量化了从口腔阶段到喉部阶段的吞咽过程。这种SSTS是非侵入性的，无线的，易于设置，并同时测量从口腔到喉部的吞咽动力学。我们建议使用的SSTS作为一种新的和非侵入性的吞咽评估工具在临床上。
The number of patients with dysphagia is rapidly increasing due to the ageing of the population. Therefore, the importance of objectively assessing swallowing function has received increasing attention. Videofluoroscopy and videoendoscopy are the standard clinical examinations for dysphagia, but these techniques are not suitable for daily use because of their invasiveness. Here, we aimed to develop a novel, non-invasive method for measuring swallowing function using a motion tracking system, the Kinect v2 sensor. Five males and five females with normal swallowing function participated in this study. We defined three mouth-related parameters and two larynx-related parameters and recorded data from 2.5 seconds before to 2.5 seconds after swallowing onset. Changes in mouth-related parameters were observed before swallowing and reached peak values at the time of swallowing. In contrast, larynx-related parameters showed little change before swallowing and reached peak values immediately after swallowing. This simple swallow tracking system (SSTS) successfully quantified the swallowing process from the oral phase to the laryngeal phase. This SSTS is non-invasive, wireless, easy to set up, and simultaneously measures the dynamics of swallowing from the mouth to the larynx. We propose the SSTS for use as a novel and non-invasive swallowing assessment tool in the clinic.
