摘　　要：目的:比较无手部抓握运动训练儿童和有手部抓握运动训练经历儿童在完成语义流畅性任务时大脑功能的不同,讨论抓握运动是否促进言语生成的表现。方法:将24名儿童按有无手部抓握运动经历,分为有运动经历和无运动经历两组,以汉语语义流畅性测验为言语任务,采用大脑功能磁共振成像(fMRI)方法,应用基于Matlab的统计参数绘图软件(SPM)分析脑区激活信息。结果:完成言语任务时两组被试产词量无显著性差异。有运动训练经历组儿童完成言语任务时大脑激活程度比无运动训练经历组强烈,激活区域范围广,主要体现在左脑岛、双侧额下回、左额叶(中央前回)。结论:抓握训练可能对汉语加工有明显影响。额叶中央前回是抓握技能对言语加工影响的重要脑区。Objective This study tried to know the differences in brain activation of children with and without grasp-related movement training while they were performing the semantic fluency task. Methods Twenty four children were divided into two groups in accordance to with or without grasp-related movement training. Semantic test was used as the verbal task. The brain activation of children was motored through functional magnetic resonance imaging while they were performing the semantic fluency task. Results Comparison of demographic and behavioral data showed no significant difference between the two groups in performance of the verbal fluency task. However, there was significant difference between two groups in statistical parametric mapping activation pattern. Significant activations were observed in left insula,bilateral inferior frontal gyrus,and the left frontal lobe （precentral gyrus）of brain. Conclusion Grasp-related movement training obviously influences the Chinese children language processing. The region for grasp-related movement that promotes speech processing locates mainly in the frontal central gyrus.
