應用於吞嚥困難評估的可攜式監測裝置

通常由中風引起的併發症，最常見的是吞嚥困難，而且吞嚥困難患者通常具有各種臨床問題，例如：營養不良，顯著的體重減輕和吸入性肺炎等…症狀。表面肌電圖（sEMG）提供了一種簡單的、非放射性的、非侵入性的方法來測量吞嚥期間肌肉活動的模式，可提供臨床醫生描述吞嚥行為的生理學。先前許多研究中已經描述了吞嚥行為的幅度和持續時間，但是沒有客觀和精確的方法來評估吞嚥時的異常會伴隨有多少潛在因子，影響患者未來可能中風的風險。為了更準確地評估吞嚥行為，本研究設計了用於吞嚥困難評估的簡易型嵌入系統之可攜式監測裝置，以便在吞嚥動作期間同時測量數個主要的肌肉群。在這種情況下，數個主要的肌肉群彼此之間互相關係的變化，其將是我們要探討的指標，該指標可以有效地反映吞嚥動作期間肌群的表面肌電圖模式之間的顯著差異。藉由研究的實驗結果，表現出吞嚥困難患者的變化指標明顯不同於健康受試者，這些關係變化之指標可作為有效的評估吞嚥肌肉之間差異跟影響患者未來潛在中風的風險。

並列摘要

One of the most common complications in patients with stroke is dysphagia swallowing difficulty. Also, such dysphagia patients usually suffer from several clinical challenges, such as malnutrition, significant weight loss, aspiration pneumonia, and so forth. Most of the previous studies have described the magnitude and duration of swallowing behavior. However, there is no objective and precise way to assess whether an abnormality in swallowing is accompanied by how many potential factors affect the risk of future stroke. To more accurately assess swallowing behavior, a simple embedded portable monitoring device for dysphagia assessment was designed for this study to simultaneously measure several major muscle groups during a swallowing session. In this case, the change in the relationship between several major muscle groups will be an indicator we will explore, which can effectively reflect the difference between the surface EMG patterns of the muscle groups during swallowing. The results of the study can show that the indicators of change in patients with dysphagia are significantly different from those in healthy subjects. These abnormal indicators can be used to effectively assess the differences between swallowing muscles and the risk of future potential stroke.
