左侧空间忽略患者远空间忽略的表现与评定研究

Far space neglect in left spatial neglect patients:features and assessment

目的探讨右脑卒中后左侧空间忽略患者的远空间忽略特点和评定。方法2021年1月至10月,北京博爱医院30例右侧脑卒中后左侧空间忽略患者(n=30,患者组)与性别、年龄和文化程度匹配的健康人(n=30,对照组)行近空间和远空间线段划销测验、星星划销测验、线段二等分测验。方便抽取对照组25例于第二天同一时间行远空间线段二等分测验。结果对照组近空间和远空间漏划线段数和百分比、漏划星星数均为零;患者组二等分测验偏离中点长度和百分比均显著大于对照组(|t|>4.319,P<0.001);患者组远空间除二等分测验的偏离中点长度显著大于近空间测验外(t=-4.994,P<0.001),其余指标与近空间测试无显著性差异(|Z|<1.638,t=-1.282,P>0.05)。二等分测验重测ICC>0.462(P<0.01)。结论左侧近空间忽略脑卒中患者可同时存在远空间忽略,二等分测验可以用于远空间忽略的评定。

Objective To explore the features and assessment for far space neglect in left spatial neglect patients after right brain stroke.Methods From January to October,2021,30 left unilateral spatial neglect(USN)patients after right stroke(patients,n=30)from Beijing Bo'ai Hospital and healthy volunteers matching with gender,age and level of education(con‐trols,n=30)were evaluated with line cancelation(LC),star cancelation(SC)and line bisection(LB)tests,near‐ly and far away.The 25 controls were evaluated with LB on the second day.Results No line or star was omissed in the controls.Both the deviation and percentage were more in the patients than in the controls(|t|>4.319,P<0.001).Both the deviation and percentage were less different for all the test(|Z|<1.638,t=-1.282,P>0.05)between nearly and far away,except the deviation of LB(t=-4.994,P<0.001).The ICC of test-retest was above 0.462(P<0.01).Conclusion Right brain stroke patients with USN may present far spatial neglect,which can be assessed with LB.
