摘要
目的研究线分法与行为偏侧忽略的相关性,探讨线分法能否预测行为偏侧忽略。方法根据行为偏侧忽略的评估量表——凯瑟林-波哥量表将30例脑卒中致左侧偏瘫的患者分为4组严重偏侧忽略组,中度偏侧忽略组,轻度偏侧忽略组和无偏侧忽略组。11例年龄匹配的健康成人作为对照组。进行线分法检查时,在A4纸的左侧、中央和右侧分别画6条水平线段,让患者用右手持圆珠笔在线的中央划一垂直分隔线。计算分隔线右侧长度占该线段全长的百分比。结果除轻度偏侧忽略组外,被分割线段空间的位置对其它各组人员的线分结果有明显影响。严重偏侧忽略组、无偏侧忽略组、对照组出现线分法中的位置“反转效应(crossovereffect)”。严重偏侧忽略组的患者在分隔A4纸左侧及中央的线段时出现向右的偏差,而在分隔A4纸右侧的线段时出现向左的偏差。在无偏侧忽略组及对照组,被检人员在分隔A4纸左侧线段时出现向左的偏差,而在分隔中央及右侧线段时出现向右的偏差。结论本研究表明线分法中的位置“反转效应”若出现在位于患者右侧的线段,则强烈提示患者有重度行为偏侧忽略。
Objective To investigate the relationship between the bisection test and the severity of behavioral hemineglect and to verify if this test can predict the behavioral hemineglect. Methods Thirty. stroke patients with left hemiparesis were divided into 4 groups according to the Catherine Bergego Scale which assessed the behavioral hemineglect: severe unilateral neglect(UN) , moderate UN, mild UN and lack of UN. Eleven healthy subjects served as age-matched control subjects. In the bisection test, eighteen lines were presented on the left, middle and right of a A4 paper respectively. The subjects were asked to place a short cross mark in the exact middle point of each line on the paper using their right hand. The proportion of the right part to the length of line for bisecting was calculated. Results In the bisection test, the main effect of space was significant in every group except the mild neglect group. The crossover effect of space location was found in the severe UN group, the group without UN and the con- trois. In the severe UN group, the patients bisected the left and middle lines with rightward bias ( percentage 〈 50% ) but bisected the right lines with leftward bias ( percentage 〉 50% ). In the group without UN and the controls, the subjects bisected the left lines with leftward bias ( percentage 〉 50% ) but bisected the middle and right lines with rightward bias ( percentage 〈 50% ). Conclusion This study showed that if the spatial crossover effect occurred in the right space condition, it was strongly supported that this patient had moderate to severe behavioral hemineglect.
