舌骨和喉复合体的运动对于防止误吸以及使药物顺利通过咽是至关重要的。我们已经开发了一种非侵入性系统，用于使用弯曲传感器测量吞咽过程中的喉部运动，并且已经报道了传感器信号波形与舌骨运动之间的时间协调。目的探讨吞咽过程中传感器输出值与舌骨运动之间的定量关系。方法13例健康男性（平均年龄30.8±4.5岁）沿颈部中线皮肤表面固定小弯曲传感器。在吞咽5ml水的过程中，通过弯曲传感器和荧光影像同步记录喉部和舌骨的运动。利用Pearson相关系数分析了所有任务和每个任务的弯曲传感器输出值（LM值）与舌骨位置（x轴位移）之间的关系，通过荧光显影从信号波形的开始到偏移。结果所有任务的LM值与舌骨位置呈正相关（x轴位移：r= 0.647，y轴位移：r= 0.233）。特别是，每个任务的LM值和x轴位移之间存在中等到高度的相关性。453≤r≤.934)。结论LM值可作为吞咽过程中舌骨前部运动的定量参数，可能与丸流和食管上括约肌开口有关。
BackgroundMovement of the hyoid and laryngeal complex is critical for preventing aspiration, as well as smooth bolus passage through the pharynx. We have developed a non‐invasive system for measuring laryngeal movement during swallowing with a bend sensor and have already reported the time coordination between the signal waveform from the sensor and hyoid movement.ObjectiveThe aim of this study was to clarify the quantitative association between the output value of the sensor and hyoid movement during swallowing.MethodsA small bend sensor was fixed on the skin surface along the midline of the neck of 13 healthy men (mean age, 30.8 ± 4.5 years). Laryngeal and hyoid movements during swallowing of 5 mL of water were recorded synchronously by the bend sensor and videofluorography. The relationship between the bend sensor output value (LM value) and hyoid position (x‐ andy‐axis displacements) by videofluorography from the onset to the offset of the signal waveform was analysed for all tasks and for each task using Pearson's correlation coefficients.ResultsThere was a positive correlation between the LM value and hyoid position for all tasks (x‐axis displacement:r= .647,y‐axis displacement:r= .233). In particular, there was a moderate to high correlation between the LM value andx‐axis displacement for each task (.453 ≤r≤ .934).ConclusionThe LM value can be a quantitative parameter of anterior hyoid movement during swallowing that might be associated with bolus flow and upper oesophageal sphincter opening.
