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.

我们开发了一种使用压电传感器的新型吞咽检查，它可以监测颈部前表面的振动，以取代导致有害辐射暴露的视频荧光摄影（VF）。使用压电传感器测量的波潜伏期预测舌骨三步运动（S1, S2, S3）的潜伏期。10名健康志愿者（平均年龄42岁，7名男性，3名女性）参加了研究。每个受试者吞下5毫升水三次，用于VF和压电传感器监测。综上所述，利用压电传感器测量的S1和S2波潜伏期可以预测舌骨第一和第二次动态运动的潜伏期。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。
