Small flexible force-sensing resistor (FSR) sensors can detect laryngeal excursion during swallowing, but the detected laryngeal excursion has not been correlated with videofluoroscopic swallowing study (VFSS) results. Here, we tested the correlation of temporal parameters between the laryngeal excursion recording by FSR sensor and the hyoid motion recording by VFSS under simultaneously swallowing test recordings. Swallowing measurements were recorded in a radiological suite by simultaneously using VFSS and FSR sensors to detect hyoid motion and laryngeal excursion, respectively. Volunteers sat with their head vertical to the Frankfort plane. Two FSR sensors, each for detecting thyroid cartilage excursion and thumb pressing, were placed. VFSS images and FSR sensor signals during single 5-mL barium liquid (30% wt/volume %) bolus swallowing were collected and analyzed for four swallows per participant. In total, 15 men (28.0 ± 4.1 years old); 14 women (28.4 ± 4.2 years old) were recruited. Temporal parameters between VFSS and noninvasive system demonstrated a strong correlation by Pearson's correlation analysis: in men (R = 0.953-0.999) and in women (R = 0.813-0.982), except for VT1-V1 compared with FT1-F1, which demonstrated a moderate correlation in women (R = 0.648; all p < 0.001). Only VT1-V1 and FT1-F1 in women displayed a significant difference (p = 0.001). Therefore, this is the first study to simultaneous record VFSS and noninvasive signals by FSR sensor. The correlation of temporal parameters between these two tests was strong. This finding is valuable for future applications of this noninvasive swallowing study tool.
小型灵活力敏电阻（FSR）传感器可检测吞咽过程中的喉部运动，但检测到的喉部运动尚未与视频透视吞咽研究（VFSS）结果相关联。在这里，我们测试了 FSR 传感器记录的喉运动时间参数与 VFSS 下的舌骨运动记录之间的相关性，这些记录是在同时吞咽测试记录下进行的。在放射科套件中，通过同时使用 VFSS 和 FSR 传感器分别检测舌骨运动和喉运动，记录吞咽测量值。志愿者头部垂直于法兰克福平面坐着。放置两个 FSR 传感器，每个传感器用于检测甲状软骨运动和拇指按压。收集并分析每个参与者的四次吞咽的单个 5 毫升钡液（30%重量/体积）吞咽时的 VFSS 图像和 FSR 传感器信号。共招募 15 名男性（28.0±4.1 岁）；14 名女性（28.4±4.2 岁）。通过 Pearson 相关分析，VFSS 和非侵入性系统之间的时间参数显示出很强的相关性：在男性（R=0.953-0.999）和女性（R=0.813-0.982）中，除了 VT1-V1 与 FT1-F1 相比，在女性中显示出中度相关性（R=0.648；所有 p<0.001）。仅女性中的 VT1-V1 和 FT1-F1 显示出显著差异（p=0.001）。因此，这是第一项同时记录 VFSS 和 FSR 传感器非侵入性信号的研究。这两项测试之间的时间参数相关性很强。这一发现对未来这种非侵入性吞咽研究工具的应用具有重要价值。
