摘要：

      摘要 目的：探讨视动刺激对视空间偏侧忽略患者的治疗效果及长期疗效。 方法：将16例首次脑卒中后出现左侧视空间偏侧忽略的患者随机分为2组，治疗组（n=8）和对照组（n=8），治疗组应用视动刺激技术（optokinetic stimulation，OKS）及传统视空间偏侧忽略的针对性训练。对照组患者仅进行传统视空间偏侧忽略的针对性训练，治疗周期均为2周。分别在基线期、治疗前、治疗后及随访末4个阶段对两组患者进行偏侧忽略纸笔测试及行为学评定。 结果：OKS组患者治疗后纸笔测试和CBS评定明显优于治疗前(P<0.01)，且效果比对照组明显(P<0.01)，治疗后2周的随访，发现治疗组效果改善持续保持(P>0.05)。 结论：视动刺激可显著改善卒中后忽略患者的忽略症状及日常行为能力。

Abstract:

      Abstract Objective:To evaluate whether optokinetic stimulation(OKS) with active pursuit eye movements could lead to substantial and greater recovery from unilateral visual spatial neglect（VSN）. Method:Sixteen post-stroke patients with left unilateral VSN were divided into treatment group(n=8),who was treated with OKS as well as conventional rehabilitation therapy，and observation group（n=8）or a control group (n=8)，who only received conventional rehabilitation therapy,all for 2 weeks.All patients were assessed with conventional paper-pencil tasks（line bisection test and star cancellation test）and behavioral assessment(Catherine Bergego scale) in four different stages(baseline,before and after treatment,2 weeks follow-up). Result:The results showed superior effects of OKS for VSN after treatment（P<0.01） and remained stable at 2 weeks follow-up(P>0.05). Conclusion:Optokinetic stimulation had significant effect on the unilateral visual spatial neglect and activities of daily living.
