A follow-up study covering two years after a closed head injury was carried out on a group of 57 young males. Their reaction time was tested on both a simple and a four choice visual reaction task. The group was divided into three subgroups according to length of unconsciousness after the injury. Reaction time discriminated between subgroups, and a highly significant improvement during follow-up was shown. Choice reaction time discriminated better and continued to do so throughout the whole period of follow-up. Some relations of reaction time with clinical variables and outcome are discussed. The choice reaction in particular seems to have some value for monitoring recovery and predicting final outcome.
对一组57名年轻男性进行了一项关于闭合性头部损伤后两年的随访研究。在简单和四选一视觉反应任务中测试了他们的反应时间。根据受伤后昏迷时间长短将该组分为三个亚组。反应时间在亚组间存在差异，且随访期间显示出高度显著的改善。选择反应时间的区分度更好，并且在整个随访期间一直如此。讨论了反应时间与临床变量和结果的一些关系。特别是选择反应似乎对监测恢复情况和预测最终结果具有一定价值。
