Abstract

Purpose: To explore efficacy of the "Rey-Osterrieth complex figure (ROCF) tracing task" as a new test to detect unilateral spatial neglect (USN).

Methods: Subjects were 40 healthy control (HC) and 20 right brain-damaged patients with (USN + , n = 10) or without USN (USN - , n = 10). After the ROCF copying task, the tracing task was performed under conditions that did not leave any tracing lines on the sample figure. Evaluation used the conventional 36-point scoring system, laterality index (LI) as the ratio of the left and right structure scores, and the number of overlaps for each of the left and right structures scored.

Results: In the tracing task, USN + showed a lower LI than HC. Furthermore, left-sided neglect was sometimes more evident than in the copying task. Regarding the total overlapping score, USN + showed a greater score than HC. The right-sided overlapping scores in USN + and USN - were also greater than that in HC. In the right brain-damaged subjects, clinically meaningful correlations were not found between evaluations in the ROCF tracing task and in conventional USN screening tests. Receiver-operating-characteristic analysis to test the power of detection showed moderate performance for the tracing LI (AUC = 0.76, 95% CI = 0.54-0.97), which was greater than that of other tests. Further, the total overlapping score in the tracing task showed sensitivity 0.9 (highest among the tests performed), specificity 0.5, and AUC 0.68 (95% CI = 0.43-0.92).

Conclusion: The ROCF tracing task might be a convenient method to detect USN and to reveal the extent of spatial working memory impairment.

利用雷伊-奥斯特里赫斯复合图形追踪任务检测单侧空间忽略的新方法：一项试验研究。

目的：探讨 "Rey-Osterrieth复合图形（ROCF）追踪任务 "作为检测单侧空间忽略（USN）的新测试的有效性：受试者为40名健康对照组（HC）和20名右脑受损患者（USN + ，n = 10）或无USN患者（USN - ，n = 10）。在完成 ROCF 复制任务后，在样本图形上不留下任何描记线的条件下进行描记任务。评估采用传统的 36 分制，侧向指数（LI）为左右结构得分之比，左右结构的重叠次数为得分：结果：在追踪任务中，USN + 的侧位指数低于 HC。此外，左侧忽视有时比复制任务更明显。在重叠总分方面，USN + 的得分高于 HC。USN + 和 USN - 的右侧重叠得分也高于 HC。在右脑受损的受试者中，ROCF 追踪任务和常规 USN 筛选测试的评估结果之间没有发现有临床意义的相关性。用于测试检测能力的受体运算特征分析表明，追踪 LI 的性能适中（AUC = 0.76，95% CI = 0.54-0.97），高于其他测试。此外，追踪任务中的重叠总分显示灵敏度为 0.9（在所有测试中最高），特异度为 0.5，AUC 为 0.68（95% CI = 0.43-0.92）：结论：ROCF追踪任务可能是检测USN和揭示空间工作记忆障碍程度的一种便捷方法。

期刊介绍： Neurological Sciences is intended to provide a medium for the communication of results and ideas in the field of neuroscience. The journal welcomes contributions in both the basic and clinical aspects of the neurosciences. The official language of the journal is English. Reports are published in the form of original articles, short communications, editorials, reviews and letters to the editor. Original articles present the results of experimental or clinical studies in the neurosciences, while short communications are succinct reports permitting the rapid publication of novel results. Original contributions may be submitted for the special sections History of Neurology, Health Care and Neurological Digressions - a forum for cultural topics related to the neurosciences. The journal also publishes correspondence book reviews, meeting reports and announcements.
