摘　　要：目的观察脑损伤患儿反应时的特点。方法65例脑损伤患儿(脑瘫50例、脑外伤13例、其他2例)为试验组,29例正常儿童为对照组,测试两组对象的反应时,并对试验组患儿进行韦氏智力测试和残疾儿童综合能力测试。结果脑损伤患儿各项反应时成绩较正常儿童明显延长(P<0.01);脑瘫患儿各项反应时成绩与脑外伤患儿比较无显著性差异(P>0.05);重度脑瘫患儿较轻、中度患儿第2反应时成绩明显延长(P<0.01);反应时与智商、综合能力评分呈明显负相关。结论脑损伤患儿的注意力和反应速度均有异常。Objective To observe the characteristic of reaction times （RTs） in the brain injury children. Methods 65 children with brain injury, including 50 cerebral palsy （CP） cases, 13 brain trauma （BT） cases and 2 other cases, were selected as the experimental group, and 29 age-matched normal children as the control group. Children of two groups were tested by the eye-hand visual reaction times （VRTs）, and children of the experimental group were also tested with Wechsler preschool and primary scale of intelligence （WPPSI）, Wechsler intelligence scale for children （WISC-R） and comprehensive function assessment. Results The VRTs of the experimental group children was significantly slower than that of the control group （P 〈0.01）. There was no significant difference in VRTs test between CP and BT children （ P 〉0.05）. The motor time of VRTs of the severe subjects in the experimental group was significantly slower than that of moderate and light subjects （P 〈0.01）. There was a negative correlation between VRTs and the scores of IQ, PIQ and the comprehensive function assessment. Conclusion The attention and the motor speed of muscles are abnormal in children with brain injury.
