Microcomputers are widely used in cognitive rehabilitation of brain damage. Unilateral neglect is commonly a target of cognitive rehabilitation, both computer-based and non-computer-based. This study reports the results of a randomized controlled trial of computer-based rehabilitation with blind follow-up for six months. Thirty-six patients with unilateral neglect, as defined by the behavioral subtests of the Behavioural Inattention Test, were randomized into two groups. One group of 20 subjects received a mean of 15.5 (SD = 1.8) hours of computerized scanning and attentional training; the second group of 16 subjects received a mean of 11.4 (SD = 5.2) hours of recreational computing (selected to minimize scanning and timed attentional tasks). Blind follow-up at the end of training and six months after revealed no statistically or clinically significant results between groups. These findings argue against routine clinical use of this type of computerized training until further studies establish what type, frequency, and duration of training produces clinically significant changes in unilateral visual neglect if, indeed, computerized training can have an effect with this type of disorder.
微型计算机在脑损伤的认知康复中被广泛应用。单侧忽视通常是认知康复的一个目标，包括基于计算机的和非基于计算机的康复。本研究报告了一项为期六个月的盲法随访的基于计算机的康复随机对照试验的结果。根据行为疏忽测试的行为子测试定义，36名单侧忽视患者被随机分为两组。一组20名受试者平均接受了15.5（标准差=1.8）小时的计算机扫描和注意力训练；另一组16名受试者平均接受了11.4（标准差=5.2）小时的娱乐性计算机操作（选择此类操作以尽量减少扫描和定时注意力任务）。训练结束时和六个月后的盲法随访显示，两组之间在统计学或临床上均无显著结果。这些发现反对在常规临床中使用这种类型的计算机训练，除非进一步的研究确定何种类型、频率和时长的训练能在单侧视觉忽视中产生临床上显著的变化，以及计算机训练是否真的能对这类疾病产生影响。
