中文摘要：

目的探讨偏侧忽略患者线段划消（Lc）和直线二等分（LB）评测表现的特点。方法对30例偏侧忽略患者进行康复治疗前、后的LB和Lc评定结果进行回顾性分析。结果在治疗前，患者在LB和Lc测试表现的偏侧忽略的差异无统计学意义（P〉0．05）。治疗后，患者在LB和LC测试表现的偏侧忽略的差异有统计学意义（P〈0．01）；LB检测出97％的偏侧忽略患者，Lc检测出73％的偏侧忽略患者。结论随着偏侧忽略的恢复，患者在LB和LC测试中所表现出的偏侧忽略程度不同。采用一种测试可能漏检偏侧忽略患者，联合两种测试对偏侧忽略的检测更加敏感。

英文摘要：

Objective To investigate the performances in line bisection （LB） and line eaneellation（ LC ） tasks of patients with unilateral neglect. Methods The unilateral neglect patients, performances in LB and LC tasks before and after rehabilitation treatment were retrospective]y analyzed. Results Before treatment, statistical analyses revealed the patients, performances in LC and LB tasks did not differ from each other （P = 0. 902）. After treatment, statistical analyses revealed a significant difference between the two tasks （P = 0. 007 ）. With LB only, 29/30 （97%） patients with neglect were detected; with LC only, 22/30 （73%） patients with negleet were detected. Conclusions As the performances of unilateral neglect patients improved, patients revealed difference between the performances in LI：I and in LC tasks. One test alone would miss some subjects with neglect. Combinative use of the two tests was more sensitive than either of the 2 tests alone.
