研究目的:

本研究旨在建立隐性误吸实时动态监测系统,为脑卒中后隐性患者的早期诊断和精准干预提供依据。首先,通过多源传感器提取吞咽过程中的声音、鼻气流、肌电图、压力和加速度等多源信号;其次,利用视频透视吞咽研究(VFSS)对提取的信号进行标记,建立数据集。第三,建立并训练基于半监督深度学习的隐性误吸实时动态监测模型。第四,通过静息态功能磁共振成像(rsfMRI),基于多源信号与岛心脑皮质-脑干功能连通性的映射关系进行模型优化。最后,通过模型优化建立隐性误吸实时动态监测系统,并通过临床应用提高敏感性和特异性。  

Objectives of Study:

The study aims to establish a real-time dynamic monitoring system of SA in five different steps, which provides evidence for the early diagnosis and precise intervention of SA patients after stroke. First, the multi-source signals including sound, nasal airflow, EMG, pressure, and acceleration signals are extracted by multi-source sensors during swallowing events. Second, the signals extracted are labeled by the videofluoroscopic swallowing study (VFSS) to establish a dataset. Third, the real-time dynamic monitoring model of SA is established and trained based on semi-supervised deep learning. Fourth, the model optimization is performed based on the mapping relationship of multi-source signals and insular-centered cerebral cortex-brainstem functional connectivity through resting state functional Magnetic Resonance Imaging (rsfMRI). Last, establish the real-time dynamic monitoring system of SA after model optimization, and increase the sensitivity and specificity by clinical application.
