在正常生理条件下，及时和充分的喉提升沿着舌骨运动是吞咽运动的重要组成部分。本研究的目的是通过评估咽部间和咽部内的可靠性来验证使用超声评估吞咽过程中舌骨移位的可重复性，并通过与视频透视吞咽研究（VFSS）的结果进行比较来检查其准确性。将自行设计的水囊固定在换能器上，使换能器与颏下皮肤接触良好。招募了10名吞咽困难的参与者。两位作者使用超声检查测量舌骨位移。所有参与者在24小时内接受超声检查和VFSS检查。两名检查者的组内相关系数（ICC）分别为0.996和0.959（p < 0.01），两名检查者之间的评分者间ICC为0.892（p < 0.05）。两名研究者的VFSS与超声之间的ICC分别为0.815和0.916（p < 0.01）。颏下超声检查是评估舌骨运动的可靠和准确的方法。
Timely and adequate laryngeal elevation along with hyoid bone movement is an essential component of the swallowing movement under normal physiological conditions. The purpose of this study was to verify the reproducibility of using ultrasonography to evaluate hyoid bone displacement during swallowing through the assessment of inter- and intrarater reliability and examine its accuracy by comparing the results with videofluoroscopic swallowing study (VFSS). A self-designed water balloon was fixed to the transducer, which provided good contact between the transducer and the submental skin. Ten participants with dysphagia were recruited. The measurements of hyoid bone displacement using ultrasonography were performed by two of the authors. All the participants underwent ultrasonographic examinations and VFSS within 24 hours. The intrarater intraclass correlation coefficient (ICC) of the two examiners was 0.996 and 0.959, respectively (p < 0.01); the interrater ICC between the two examiners was 0.892 (p < 0.05). ICCs between VFSS and ultrasonography for two researchers were 0.815 and 0.916 (p < 0.01). Submental ultrasonography is a reliable and accurate method for assessing the hyoid bone movement.
