目的 探讨虚拟现实棱镜适应训练对脑卒中后视空间忽略的康复作用及其脑机制.方法 将脑卒中视空间忽略患者30例按随机数字表法随机分为治疗组和对照组,治疗组采用虚拟现实棱镜适应训练和常规康复治疗2周,对照组只进行常规康复治疗.2组患者均于治疗前和治疗2周后（治疗后）采用字直线二等分测试（LBT）、字母划销试验（LCT）、画钟试验（CDT）和注意网络测试（ANT）进行评定.结果 治疗前,2组患者间的LBT、LCT和CDT测试间比较,差异均无统计学意义（P＞0.05）；治疗后,治疗组患者的LBT、LCT、CDT测试结果分别为（4.27±1.39）分、（9.5±6.95）％、（8.80±1.01）分,与组内治疗前和对照组治疗后比较,差异均有统计学意义（P＜0.01）.治疗前,2组患者间ANT测试各项指标比较,差异均无统计学意义（P＞0.05）；治疗后,治疗组ANT测试各项指标与组内治疗前和对照组治疗后比较,差异均有统计学意义（P＜0.05）.结论 虚拟现实棱镜适应训练结合常规康复作业治疗能更好地改善脑卒中患者视空间忽略症状.

英文摘要：

Objective To investigate the effects of virtual reality prism adaptation on visuospatial neglect in stroke patients.Methods Thirty stroke patients with visuospatial neglect were studied.The subjects were divided into atreatment group and a control group.The subjects in the treatment group were treated with virtual reality prism adaptation and routine rehabilitation interventions for 2 weeks,while those in the control group were treated with routine rehabilitation interventions only.All the patients performed a battery of spatial attention tests including line bisection,letter cancellation,clock drawing and the Attention Network Test at the beginning and after 2 weeks of treatment.Results The virtual reality prism adaptation training had significant positive effects on all the measures of visuospatial neglect.Pair-wise comparisons confirmed significant differences between the treatment and control groups after 2 weeks of treatment with regard to all of the measures.Conclusions Virtual reality prism adaptation treatzment combined with routine rehabilitation can be more effective than conventional measures alone in improving the visuospatial performance of stroke survivors.
