目的探讨8种国内、外较常用的单侧空间忽略检测方法的敏感性及影响因素。方法应用删除试验、数字消去法、平分直线法、画钟试验、自由画图、字体试验、临摹画图、目测黑点数等8种单侧空间忽略检测方法对400名正常人进行量化评定,同时对随机选择的33例脑卒中患者进行临床检测。结果正常人字体试验和目测黑点数的检测结果全部正常,其它方法的检测结果均有不同程度的异常。自由画图、画钟试验、平分直线法和临摹画图的异常率随被检者年龄的增长、文化程度的降低而增高。临床应用中,数字消去法、目测黑点数和字体试验检出率较低,分别为71.43%、57.13%和42.86%,其他方法检出率均为100%。结论不同的检测方法的敏感性和影响因素不同,单纯采用一种检测方法不能明确被检者是否存在单侧空间忽略,多种方法同时应用可提高检出率。
Objective To explore the sensitivity and influencing factors of eight unilateral spatial neglect detection methods commonly used at home and abroad. Methods Eight unilateral spatial neglect detection methods such as deletion test, digital subtraction method, bisect straight line method, draw bell test, free drawing drawing, font test, copy drawing and visual black spots were used to quantify and evaluate 400 normal persons. Meanwhile, Selected 33 cases of stroke patients for clinical testing. Results The results of fonts test and black spot test of normal people were all normal. The test results of other methods had different degrees of abnormalities. Free drawing, drawing bell test, bisect straight line method and copy the abnormal rate of painter with the age of the subjects increased, lower education level increased. Clinical application, digital elimination method, visual black spots and font test detection rate was low, respectively, 71.43%, 57.13% and 42.86%, other methods were 100% detection rate. Conclusion The sensitivity and influencing factors of different detection methods are different. Simply using one detection method can not make clear whether the subjects have unilateral spatial neglect. Multiple methods can be used simultaneously to improve the detection rate.
