Patients suffering from Unilateral Spatial Neglect (USN) fail to pay attention to, respond to, and report sensory events occurring in the contralesional side of space. The traditional neuropsychological assessment of USN is based on paper-and-pencil tests, whose data recording and scoring may be subjected to human error. The utilization of technological devices can be expected to improve the assessment of USN. Therefore, we built Neurit.Space, a modified digital version of three paper-and-pencil tests, widely used to detect signs of USN, namely: Bells Cancellation, Line Bisection and Five Elements Drawing Test. Administration and data processing is fully automatic. Twelve right brain-damaged patients (six with and six without USN) and 12 age- and education-balanced healthy participants were enrolled in the study. All participants were administered both the computerized and the paper-and-pencil versions of the tests. The results of this preliminary study showed good sensitivity, specificity, and usability of Neurit.Space, suggesting that these digital tests are a promising tool for the evaluation of USN, both in clinical and in research settings.
患有单侧空间忽视（USN）的患者无法注意到、对发生在空间对侧的感觉事件做出反应并进行报告。传统的USN神经心理学评估基于纸笔测试，其数据记录和评分可能会出现人为错误。预计使用技术设备可以改善USN的评估。因此，我们构建了Neurit.Space，这是三个纸笔测试的改进数字版本，广泛用于检测USN的体征，即：铃声消除、线段二等分和五行绘图测试。管理和数据处理完全自动化。12名右脑损伤患者（6名有USN，6名无USN）和12名年龄和教育程度均衡的健康参与者参与了该研究。所有参与者都接受了测试的计算机化版本和纸笔版本。这项初步研究的结果显示了Neurit.Space良好的敏感性、特异性和可用性，表明这些数字测试是在临床和研究环境中评估USN的一个有前景的工具。
