Prism adaptation (PA) is one of the most effective treatments for the rehabilitation of unilateral spatial neglect. Optokinetic stimulation (OKS) has also been demonstrated to be effective in ameliorating symptoms of neglect. The aim of this study is to compare the effectiveness of these two methods in a group of neglect patients using a crossover design. A group of 13 post-acute brain-damaged patients with unilateral spatial neglect, who had never been rehabilitated, were treated using PA and OKS. Each treatment was applied for 10 sessions, twice a day, to all patients with both treatments in crossed order (i.e., PA followed by OKS or vice versa). Neuropsychological assessments were performed: before the first (T1), at the end of the first/beginning of the second (T2) and at the end of the second training sessions (T3), and two weeks after the end of treatment (T4). Both procedures produced a significant improvement in clinical tests at T2, independent of the type of training. The results suggest that either PA or OKS induces a significant amelioration of neglect in right brain-damaged patients, mainly in the first block of treatment. Since no differences between treatments were found, they could be applied in clinical practice, according to the requirements of the individual patient.
棱镜适应（PA）是单侧空间忽视康复治疗中最有效的方法之一。视动刺激（OKS）也已被证明在改善忽视症状方面有效。本研究的目的是采用交叉设计比较这两种方法在一组忽视患者中的有效性。一组13例急性脑损伤后单侧空间忽视且从未接受过康复治疗的患者接受了PA和OKS治疗。每种治疗对所有患者均进行10次，每天两次，两种治疗以交叉顺序进行（即PA后接OKS或反之）。进行了神经心理学评估：在第一次治疗前（T1）、第一次治疗结束/第二次治疗开始时（T2）、第二次训练结束时（T3）以及治疗结束后两周（T4）。两种治疗方法在T2时的临床测试中均产生了显著改善，与训练类型无关。结果表明，PA或OKS均可使右脑损伤患者的忽视症状得到显著改善，主要在治疗的第一阶段。由于未发现治疗之间的差异，可根据个体患者的需求将它们应用于临床实践。
