运用α和β频带脑电功率分析八段锦对不同神经质人格大学生“调心”效应差异

Neurotic Personality Specific Study on Psychological Adjustment Induced by Baduanjin by using α and β band Electroencephalogram Power

目的基于α、β频带脑电功率分析八段锦的"调心"效应及其人格特征。方法根据艾森克人格问卷简式量表中国版(EPQ-RSC)中的N量表(代表神经质,即情绪稳定性)将符合入组标准的大学生分成不同人格组,均接受八段锦训练,比较两组α、β频带平均功率在总体和空间(导联)的差异。结果八段锦训练后,在α1、α2和β1、β2频带总体平均功率,中间型人格组显著高于训练前(皆P≤0.01),情绪稳定型人格组与训练前比较皆无统计学差异(皆P>0.05),且情绪稳定型人格组在训练后各频带的总体平均功率皆显著低于中间型人格组(皆P≤0.01);训练后,中间型人格组在α1和α2频带平均功率皆呈全脑区同步性显著增高的特征,在顶区、右枕区和后颞区尤为明显;β1和β2频带平均功率在大部分脑区也呈同步性增高的特征,在顶区或颞区增高明显。情绪稳定型人格组除了α1频带平均功率在大部分脑区普遍同步性增高趋势外,其余频带平均功率则普遍呈同步性降低趋势。结论八段锦训练能够诱发"调心"作用,在大学生α1和α2、β1和β2频带平均功率的总体及空间变化上皆存在明显人格特异性,这可能是八段锦能够改善不同神经质人格大学生不良心理状态的大脑生理机制之一。

Objective To analyze the neurotic personality-dependent differences of the psychological adjustment induced by baduanjin(eight-section brocade) by comparing the changes of α and βelectroencephalogram(EEG) power among different neurotic personality students before and after performing baduanjin. Methods College students were recruited as volunteers, and were divided into different neurotic personalities group according to N scale(representing the neuroticism) in EPQ-RSC. All volunteers received baduanjin training. α and βEEG average power of different groups was measured and compared with NT9200 electroencephalograph before and after performing baduanjin. The results were collected to analyze the differences of absolute power in different groups before and after baduanjin training.Results Compare with before training the average power of theα1, α2 and β1, β2 band were increasing in the intermediate personality group after training(all P < 0.01), while there was no significant difference in the absolute power of theα1, α2 and β1, β2 band of emotional stability personality group after training(all P > 0.05). In addition, the absolute power of theα1, α2 and β1, β2 band in the emotional stability personality group were significantly lower than that in the intermediate personality group after training(all P < 0.01). And the distribution ofα1 and α2 bands in the intermediate personality group presented an increasing tendency on the whole brain region after training, especially in the parietal region, right occipital region, and posterior temporal region. And the distribution of β1 and β2 bands in the intermediate personality group also presented an increasing tendency on the most of brain region after training,especially in the parietal region and temporal region. While the distribution ofα1 in the emotional stability personality group presented an increasing tendency on the most of brain region after training, but the distribution of other bands in the emotional stability personality group presented an decreasing tendency on the most of brain region after training.Conclusion "Psychological adjustment"may be induced by baduanjin training in college students with different neurotic personality, which effect shows obvious personality specificity in the total and spatial changes of α1, α2 and β1,β2 bands average power. This may be one of the brain regulating mechanisms that can comprehensively improve the mental health of college students with different neurotic personality who practicing baduanjin training.
