临床应用一种微创、客观评价的吞咽功能评价系统是必要的。我们构建了一个系统，可以同步和分析唇部运动与三维（3D）相机和吞咽动态与视频透视（VF），阐明唇部运动和吞咽动力学之间的关系。紧凑型3D相机适用于Microsoft XBox One Kinect Sensor®。我们检查了Kinect的准确性和可重复性，并分析了最高的测量精度和口角肌肉之间距离的可重复性。所构建的系统通过Kinect同时测量、同步和分析嘴唇运动，通过VF同时测量、同步和分析吞咽动态。纳入14名无吞咽困难的老年男性。用钡浊液（5、10、15、20 mL）进行吞咽。测量参数为口角位移（TDDD）、吞咽量（SQ）、口腔传递时间（OTT）、阶段传递时间（STD）、咽部传递时间（PTT）和总吞咽时间（TSD）之间的三维距离。进行统计学分析。在水平成像角度为10°，测量距离为120 cm时，测量精度和重现性最佳。SQ、TDDD、OTT、STD、PTT、TSD存在显著性差异，TDDD与OTT存在相关性。SQ影响TDDD、OTT、STD、PTT和TSD；OTT可以通过TDDD预测。系统和分析方法的改进被认为能够从头部和颈部的体表运动预测吞咽动力学，包括实现更高精度和可重复性的测量条件，以及从嘴唇运动。
Clinical application of a swallowing function evaluation system that is minimally invasive and enables an objective evaluation is necessary. We constructed a system that can synchronise and analyse lip motion with a three‐dimensional (3D) camera and swallowing dynamics with videofluoroscopy (VF) and clarified the relationship between lip movement and swallowing dynamics. A compact 3D camera was adapted to Microsoft XBox One Kinect Sensor®. We examined Kinect's accuracy and repeatability and analysed the highest measurement accuracy and repeatability of the distance between anguli oris muscles. The constructed system simultaneously measured, synchronised and analysed lip motion by Kinect and swallowing dynamics by VF. Fourteen elderly men without dysphagia were included. Barium turbid solution (5, 10, 15 and 20 mL) was used for swallowing. Measurement parameters were the 3D distance between angulus oris displacement (TDDD), swallowing quantity (SQ), oral transit time (OTT), stage transit duration (STD), pharyngeal transit time (PTT) and total swallowing duration (TSD). Statistical analyses were performed. The measurement accuracy and reproducibility were optimum within a 10° horizontal imaging angle at a 120‐cm measurement distance. SQ, TDDD, OTT, STD, PTT and TSD showed significant differences, and correlation was found between TDDD and OTT. SQ affected TDDD, OTT, STD, PTT and TSD; OTT could be predicted from TDDD. Improvement in the system and analysis method was considered to enable prediction of swallowing dynamics from body surface movement of the head and neck, including realisation of measurement conditions with higher precision and reproducibility, and from lip motion.
