| Research Abstract |
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.
