目的：我们报告了苹果测试验证和功能相关性的数据，该测试试图区分不同形式的单侧忽视。方法：研究1提供了25名慢性脑损伤患者的数据，他们完成了苹果测试和另一种忽视标准测量（星星取消）。评估了患者相对于86名对照者的表现，并比较了他们在两次测试中的相对表现。研究2招募了115名急性中风患者，他们完成了苹果测试，这是伯明翰大学认知筛查程序的一部分。我们评估了不同形式的忽视之间的关系。研究3考察了急性卒中患者忽视类型（用苹果测试测量）与其日常生活能力和活动影响的关系。结果：在研究1中，苹果的测试分数与星星抵消性能相关，同时也区分了忽略整个页面和忽略部分对象之间的差异。研究2证实了与研究1的分离。“纯粹”形式的忽视在左右脑损伤后同样普遍，而两种缺陷的存在都与右脑损伤有关。研究3表明，每一种形式的忽视也与其他认知指标相关。与纯粹的基于页面的忽视相比，以对象为中心的忽视与较低的Barthel评分相关（p < 0.001），而两种形式的忽视的患者比纯粹形式的忽视的患者有更高的抑郁水平（p < 0.001）。结论：我们得出结论，苹果测试提供了临床适用的不同形式的忽视措施。此外，它是一个有用的预测功能结果。我们讨论的性质两种形式的忽视诊断的测试和功能的影响。
Objective: We report data on the validation and functional correlates of Apples Test, which attempts to differentiate between different forms of unilateral neglect. Method: Study 1 presents data from 25 participants with chronic brain lesions who completed the Apples Test and another standard measure of neglect (Star Cancellation). The patients' performance relative to 86 controls was assessed and their relative performance across the two tests compared. Study 2 recruited 115 acute hospital stroke patients who completed the Apples Test as part of the Birmingham University Cognitive Screen procedure. We assessed the relations between the different forms of neglect. Study 3 examined neglect type (as measured by the Apples Test) among the acute stroke group in relation to their activities of daily living abilities and affect. Results: In Study 1 Apples Test scores correlated with Star Cancellation performance, while also differentiating between neglect across the page and neglect of parts of objects. Study 2 confirmed the dissociation from Study 1. "Pure" forms of each type of neglect were equally prevalent after right and left hemisphere lesions, while the presence of both deficits was associated with right hemisphere damage. Study 3 showed that each form of neglect also correlated with other measures of cognition. When compared with pure page-based neglect, object-centered neglect was associated with a lower Barthel score (p < .001), while patients with both forms of neglect had higher level of depression (p < .001) than those with the pure forms. Conclusions: We conclude that the Apples test provides a clinically applicable measure of different forms of neglect. In addition it is a useful predictor of functional outcome. We discuss the nature of the two forms of neglect diagnosed by the test and the functional implications.
