技術說明

睡眠是影響生活品質不可或缺的一環，人類一生會花上三分之一的時間在睡眠上，但並不是所有人都能擁有良好的睡眠品質，因此在臨床上多半會使用多通道睡眠紀錄儀器 (PSG) 紀錄並藉此觀察患者的睡眠品質以助症狀的診斷。然而，人工睡眠判讀是一項十分耗時的作業，此外睡眠紀錄儀器必需使用較多電極，不僅操作困難，對患者在睡眠品質上亦有較大的干擾，使得判讀結果無法真正反映病患平日的睡眠情況。因此本技術利用較不干擾睡眠的眼動電訊號(EOG)開發一套自動睡眠判讀演算法。 經過訊號的前處理後，我們使用眼動電訊號頻道來同時擷取眼動特徵與部分的睡眠腦電訊號的特徵，並使用正規化來減少特異特徵的差異性。接著把特徵輸入至一個決策樹分類器來達到自動分期的目的。最後再使用一些平滑化規則來提升準確率，其結果與專家的一致率可以達到83.08%的整體一致性，證明眼動訊號在睡眠階段分類上的可用性，未來勢必可取代一般腦電圖紀錄並應用於臨床或簡易居家健康照護系統等相關領域上。 Sleep is very important for human beings. However there’s not everyone who can acquire good sleep quality. Thus on the clinical diagnosis, doctors use polysomnographic (PSG) recording to analyze and evaluate sleep quality of patients and diagnosis specific sleep diseases. Nevertheless, visual sleep scoring is a time consuming and subjective process. Besides, the large amount of wires for conventional PSG often makes disturbance to user. Our goal is to design an automatic sleep staging method based on EOG which disturbs the user sleep much less than PSG recordings. We found that EOG can not only capture the eye movement activity but some patterns from EEG signs. This made the sleep scoring based on EOG become available. Our method reached overall 83.08% agreement. The result proved that the EOG channel is useful on sleep staging as EEG did and supports the development on self-applicable sleep monitoring device for further application.
