经颅直流电刺激对健康青年军人注意训练效果的提升作用

Effect of Transcranial Direct Current Stimulation on Attention Training in Healthy Young Soldiers

目的探讨经颅直流电刺激(transcranial direct current stimulation,tDCS)对健康青年军人注意训练的提升效果。方法采用两因素完全随机设计,选取42名被试者随机分为tDCS+训练组、单纯训练组,完成了3次干预,干预方式为tDCS联合注意训练与单纯注意训练。结果(1)通过重复测量方差分析发现,两组被试的注意功能均有不同程度提升(P均<0.05)。(2)tDCS+训练组成绩第2次干预时就发生了显著改变,较单纯训练组早。结论tDCS联合注意训练与单纯注意训练均能提升健康青年军人的注意功能,但tDCS能够促进注意训练效果提前出现。

Objective To investigate the effect of transcranial direct current stimulation(tDCS)on attention training of healthy young soldiers.Methods A total of 42 subjects were randomly divided into tDCS+training group and training group by a two-factor completely random design,and 3 interventions were completed,including tDCS combined with attention training and attention training alone.Results(1)The attention function of two groups was improved(all P<0.05)by repeated measure analysis of variance.(2)The results of tDSC+training group were significantly changed earlier than that of training group,and significant changes occurred at the second intervention in tDSC+training group.Conclusion tDCS combined with attention training and attention training alone can both promote the attention function of healthy young soldiers,but tDCS can promote the effect of attention training in advance.
