Abstract

The neurogenic oropharyngeal dysphagia is a prevalent functional swallowing disorder resulting from neurological causes. The conventional diagnosis involves ionizing radiation in Videofluoroscopy Swallowing Studies (VFSS). Surface electromyography (sEMG) offers a non-invasive alternative by recording muscle activity. This research compares bolus passage timing through anatomical structures using VFSS and sEMG-related activation times. Fifty confirmed oropharyngeal dysphagia patients underwent synchronized VFSS and sEMG, evaluating muscle groups during cracker and fluid ingestion. sEMG revealed activation patterns in masseters, suprahyoid, and infrahyoid muscles, occurring before bolus passage through the mandibular line and concluding near the upper esophageal sphincter complex. sEMG identified differences in dysphagia severity (EAT-10 score), age, and diagnosis, contrasting VFSS results. Results indicate potential complementarity between sEMG and VFSS for dysphagia screening, diagnosis, and monitoring.

作为 VFSS 辅助工具的 sEMG:对神经源性口咽吞咽困难患者的同步研究
神经源性口咽吞咽困难是一种普遍存在的由神经原因引起的功能性吞咽障碍。传统的诊断方法是利用电离辐射进行视频荧光吞咽检查(VFSS)。表面肌电图(sEMG)通过记录肌肉活动提供了一种无创的替代方法。这项研究使用 VFSS 和 sEMG 相关激活时间比较了栓剂通过解剖结构的时间。50 名确诊为口咽吞咽困难的患者接受了同步 VFSS 和 sEMG 检查,评估了摄入饼干和液体时的肌肉群。sEMG 显示了肌肉群、舌骨上肌和舌骨下肌的激活模式,发生在栓子通过下颌线之前,在食管上括约肌复合体附近结束。结果表明,sEMG 和 VFSS 在吞咽困难筛查、诊断和监测方面具有潜在的互补性。
