导言。开发一种治疗吞咽障碍的自动化诊断和治疗仪器需要能够可靠地检测和评估吞咽的程序。我们测试了一种基于肌电/生物阻抗(EMBI)联合测量系统的两阶段检测程序。EMBI能够检测燕子，并将它们与健康测试对象的类似动作区分开来。研究设计。这项研究是作为病例对照研究计划和进行的(EA 1/019/10和EA1/160/09、EA1/161/09)。方法。这项研究观察了健康受试者和口咽吞咽障碍患者在吞咽过程中吞咽参数的总体差异和穿透情况。提出了一种利用肌电(EMG)和生物阻抗(BI)对燕子进行可靠检测的两阶段自动燕子检测方法。结果。以前用于区分吞咽和头部运动的吞咽参数在健康受试者和吞咽障碍患者之间发现了统计上的显著差异。基于这些差异，我们的两阶段算法能够可靠地检测燕子(敏感性=96.1%，特异性=97.1%)。讨论。使用两阶段检测程序，EMBI测量程序能够自动和可靠地检测和评估燕子。这两个程序(EMBI+吞咽检测)可能在未来形成吞咽障碍的自动诊断和治疗(刺激)的基础。
Introduction. Developing an automated diagnostic and therapeutic instrument for treating swallowing disorders requires procedures able to reliably detect and evaluate a swallow. We tested a two-stage detection procedure based on a combined electromyography/bioimpedance (EMBI) measurement system. EMBI is able to detect swallows and distinguish them from similar movements in healthy test subjects. Study Design. The study was planned and conducted as a case-control study (EA 1/019/10, and EA1/160/09, EA1/161/09). Method. The study looked at differences in swallowing parameters in general and in the event of penetration during swallows in healthy subjects and in patients with an oropharyngeal swallowing disorder. A two-stage automated swallow detection procedure which used electromyography (EMG) and bioimpedance (BI) to reliably detect swallows was developed. Results. Statistically significant differences between healthy subjects and patients with a swallowing disorder were found in swallowing parameters previously used to distinguish between swallowing and head movements. Our two-stage algorithm was able to reliably detect swallows (sensitivity = 96.1%, specificity = 97.1%) on the basis of these differences. Discussion. Using a two-stage detection procedure, the EMBI measurement procedure is able to detect and evaluate swallows automatically and reliably. The two procedures (EMBI + swallow detection) could in future form the basis for automated diagnosis and treatment (stimulation) of swallowing disorders.
