半側忽略症是腦神經系統發生問題，而出現難以察覺、探索腦傷對側的空間的一種疾病。因腦傷的範圍廣泛不定，它常常與其他症狀一起發生，如半側癱瘓、病覺缺失等問題，所以是一種複合型的症候群。因此傳統的單一療法其實是不夠的，應該結合多種療法才能對應到不同的症狀。本篇研究之主要目的是發展一套電腦化、具有自身影像之視覺回饋的即時互動復建軟體，幫助半邊忽略症患者的復健。受試者為二位患有左側視覺忽略症的中風患者與一位正常人，兩位病患在8周內使用本軟體做了18次實驗，正常人則做了10次實驗，兩者再互相做比較。本軟體利用影像處理演算法，將患者的上半身身體影像與背景環境分離，僅投射個人影像到電腦螢幕中，使患者能夠看到自身影像，如此一來不但增加視覺回饋使整體感覺一致性提高，也能減輕病覺缺失和重建空間表徵。透過手勢判別技術辨別患者所做的手勢，患者能與螢幕上利用軟體所顯示的刺激進行互動，達到復健效果。此軟體將近幾年來所發展的多種忽略症療法概念結合，患者可同時接受多種不同的刺激，有助於腦神經連結重塑。結果顯示兩位病患在專注力、星星刪除測驗、線二分段測驗與簡易心智量表都有進步，但線刪除測驗則沒有太大的差別。與近幾年來的研究比較，本軟體改善了病人的忽略症情形，依照本研究的結果來看，是幫助改善忽略症的一種新穎的療法。

Visual spatial neglect is a neurological syndrome characterized by a lack of awareness and explorative behaviors toward the patients’ contralesional hemispace. It is a multicomponent disorder that is often combined with hemiplegia and anosognosia. Therefore, this multicomponent disorder should be treated with multiple therapies. The purpose of this study was to develop a real-time interactive training system to rehabilitate patients with visual spatial neglect. Two cases of left visual spatial neglect and one normal case were included. The patients were trained 18 times over 8 weeks, and the results were compared to those of the normal subject who received 10 training sessions. The interactive software uses an image processing algorithm to separate the body image of the patient from a background image, thus revealing only the patient’s image on the screen. The patient sees their image, which increases visual feedback and enhances the integrity of their sensory inputs. Therefore, this therapy decreases the severity of anosognosia, allowing the patient to reconstruct their spatial representation. The hand gesture recognition technique allows the patient to interact with the application. This software combines concepts from different therapies to reconstruct brain neurons. The results showed that patients improved attention ability, Star Cancellation, Line Bisection, and Mini Mental State Examination test scores, but no improvements on the Line Cancellation Test was observed. This software helped the patients free themselves from the symptoms of visual neglect and may be a beneficial therapeutic technique.
