Unilateral spatial neglect (USN) is a frequent consequence of acquired brain injury, especially following right hemisphere damage. Traditionally, unilateral spatial neglect is assessed with cancellation tests such as the Bells test. Recently, a new cancellation test, the Apples test, has been proposed. The present study aims at comparing the accuracy of these two tests in detecting hemispatial neglect, on a sample of 56 right hemisphere stroke patients with a diagnosis of USN. In order to evaluate the agreement between the Apples and Bells tests, Cohen's kappa and McNemar's test were used to assess differences between the two methods of evaluation. Poor agreement and statistically significant differences emerged between the Apples and Bells tests. Overall, the Apples test was significantly more sensitive than the Bells test in detecting USN. Based on these results, the use of the Apples test for peripersonal neglect assessment is therefore highly recommended.
单侧空间忽略（USN）是获得性脑损伤的常见后果，尤其是在右半球损伤后。传统上，单侧空间忽略通过 Bell 测试等取消测试进行评估。最近，提出了一种新的取消测试，即 Apples 测试。本研究旨在比较这两种测试在检测半空间忽略方面的准确性，使用的样本是 56 名被诊断为单侧空间忽略的右半球中风患者。为了评估 Apples 测试和 Bell 测试之间的一致性，使用 Cohen 的 kappa 和 McNemar 的检验来评估两种评估方法之间的差异。Apples 测试和 Bell 测试之间的一致性较差，且差异具有统计学意义。总体而言，Apples 测试在检测 USN 方面比 Bell 测试更敏感。基于这些结果，强烈建议使用 Apples 测试进行近旁忽略评估。
