【摘要】 目的 观察重复经颅磁刺激对甲基苯丙胺依赖者注意偏向的影响。方法 将50例甲基苯丙胺依赖者按总反应时的高低次序,随机分为研究组和对照组,研究组用重复经颅磁真刺激,对照组则用重复经颅磁假刺激。在治疗前后应用成瘾Stroop任务测试甲基苯丙胺依赖者的注意偏向。结果 治疗后,研究组较对照组甲基苯丙胺相关字词平均反应时要快(P <0.05),但两组中性字词平均反应时及错误数差异均无统计学意义(P>0.05);与治疗前相比,研究组治疗后甲基苯丙胺相关字词平均反应时和中性字词平均反应时更快(P<0.05),错误数差异无统计学意义(P>0.05),而对照组各指标治疗前后比较差异均无统计学意义(P>0.05)。结论 重复经颅磁刺激可以在一定程度上改善甲基苯丙胺依赖者的注意偏向。更多还原

【Abstract】 Objective To explore the effect of repetitive transcranial magnetic stimulation(rTMS)on the attention bias of methamphetamine-dependent patients.Methods A total of 50 methamphetaminedependent patients were randomly divided into two groups in the order of total reaction time:the experimental group and the control group.Real rTMS was used in the experimental group and fake rTMS was used in the control group.The Addictive Stroop Task was used to test the attention bias of methamphetaminedependent patients before and after the treatment.Results After the treatment,the average reaction time of methamphetamine-related words in the experimental group is significantly shorter than that in the control group(P <0.05).However,there was no statistically significant difference in the average reaction time of neutral words between the two groups(P> 0.05).In the experimental group,the average reaction time of methamphetamine-related words and neutral words after the treatment was shorter than before the treatment(P <0.05),while the accuracy rate showed no significant difference before and after the treatment(P> 0.05).In the control group,there was no difference in the average reaction time of methamphetamine-related words and neutral words and the accuracy rate before and after the treatment(P> 0.05).Conclusions To some extent,the rTMS treatment can improve the attention bias of methamphetamine-dependent patients.更多还原
