康复训练对脑损伤患儿视觉反应时的影响

目的了解康复训练对脑损伤患儿视觉反应时的影响及其在残疾儿童脑功能评价和康复疗效分析中的作用。方法观察组为51例脑损伤患儿，对照组为29例正常儿童，均进行光刺激的复杂视觉反应时测试，并比较观察组康复训练前、后的反应时成绩。结果观察组训练前各项反应时成绩明显较对照组延长（P〈0．01）。训练后观察组的反应时成绩则明显改善（除左侧第二反应时），第一反应时与对照组差异无统计学意义（P〉0．05）；中度障碍的观察组患儿训练后反应时的改善程度最明显。结论脑损伤患儿注意力和反应速度均有异常，但经过训练后可有明显改善。反应时作为一种简单、易测、灵敏、客观的神经心理活动指标，在残疾儿童高级脑功能评价和康复疗效分析中具有重要意义。

The effect of the rehabilitation on reaction times of children with brain injury

Objective To elucidate the effect of rehabilitation training on visual reaction times of children with brain injury. Methods Fifty-one children with brain injury recruited for the observation group were observed, 29 age-matched normal children served as the controlsubjects. All the children in both groups were tested in terms of the eye-hand visual reaction times(VRTs). All the patients were given rehabilitation treatment. Results Before rehabilitation treatment, the VRTs of the observation group were significantly slower than those of the control group (P<0.01). After treatment, the scores of VRTs, except for the motor-reaction time of the left side, of the observation group were significantly increased (P<0.01). And the score of premotor time of VRTs of the observation group was not significantly different from those of the control group (P>0.05). Conclusion The attention and the motor speed were abnormal in children with brain injury, rehabilitation treatment can improve the reaction times significantly. The test of RTs could be of great importance in the evaluation of neurobehavior and therapeutic effect for children with brain injury, because of its easiness, sensitiveness and objectiveness in clinical application.
