We developed a novel swallowing examination using the Piezo-sensor, which monitors vibrations on the surface of the anterior neck, in place of videofluorography(VF), which causes harmful radiation exposure. The latencies of waves measured using the Piezo-sensor predicted the latencies of the 3-step motion(S1, S2, S3) of the hyoid bone. Ten healthy volunteers(mean age : 42 years ; 7 men, 3 women) participated. Each subject swallowed 5 ml water three times for VF and Piezo-sensor monitoring. In conclusion, the S1 and S2 wave latencies measured using the Piezo-sensor predicted the latencies of the first and second dynamic motions of the hyoid bone. These findings demonstrate that examination using the Piezo-sensor will be useful for analyzing swallowing function in place of VF.

我们使用压电传感器开发了一种新颖的吞咽检查，该检查可监视前颈表面的振动，代替视频摄影（VF），这会导致有害的辐射暴露。使用压电传感器测量的波的潜伏期预测了舌骨的3步运动（S1，S2，S3）的潜伏期。十名健康志愿者（平均年龄：42岁； 7名男性，3名女性）参加了会议。每个受试者吞咽了5毫升水，用于VF和压电传感器监测。总之，使用压电传感器测量的S1和S2波延迟预测了舌骨的第一和第二动态运动的潜伏期。这些发现表明，使用压电传感器的检查将有助于分析吞咽功能代替VF。
