| Research objectives:In recent years,with the aging of China's population,the incidence of senile diseases hasbeen increasing year by year.A large number of studies show sports exercise can delay the incidence of this disease.In this paper,brave wave data is used to verify and analyze the effect of Health Qigong Baduanjin on the improvement of the old people's cognitive function.Research methods:The elderly with mild cognitive impairment were subjected to a 16-week Health Qigong exercise intervention and brain power spectrum analysis was performed after.Before the experiment,all subjects were evaluated by the Montreal Cognitive Function Scale,the Minimal Spiritual Scale,and the brain electrical signals.They were randomly divided into two groups.The first group was designed to do Healthy Qigong exercise with group members of 15 while the other group is the control group of 15 people.The changes in brain power distribution before and after the experiment were observed.All data were statistically analyzed with SPSS17.0 software.Differences were considered statistically significant when the P value was less than 0.05.Research results:1.Both the MMSE and MoCa scale score do not have statistic significance(P>0.05)before and after the experiment.However,in the MoCA scale,the experimental group scored higher than the control group in terms of spatial execution ability,which was of statistical significance(P<0.05).Comparison between groups before and after the experiment shows that the absolute power values of the four wave bands in the experimental group increased in a quiet,eyes closed state(P<0.05).2.Compared with the control group after the experiment,the relative power values of?wave,?wave and?wave of the experimental group were lower than that before the experiment,for the?wave,the control group was 0.422±0.110,and the experimental group was 0.370±0.055(P<0.01);For the relative power valuesof the?wave,the control group was0.054±0.012 and the experimental group was 0.047±0.009(P<0.01);For the relative power values of the?wave,the control group was 0.118±0.025 and the experimental group was 0.106±0.017(P<0.01);However,the relative power values of the?wave increased,the control group was 0.404±0.092and the experimental group was 0.476±0.056(P<0.01).3.Through a comparison among different brain regions,it has been found that the power value of?wave in frontal region is 0.252±0.053?v~2 in experimental group and 0.408±0.117?v~2(P<0.01)in control group,as the subjects kept their eyes closed.However,in central region,the value is 0.281±0.051?v~2in experimental group and 0.218±0.027?v~2(P<0.05)in control group.There was no statistical significance in the rest of the brain regions as the eyes open or closed.The power value of?wave in frontal region is 0.095±0.023?v~2 in experimental group and 0.056±0.005?v~2(P<0.01)in control group as the eyes closed.The?wave was of statistical significance(P<0.01)in all the five brain regions as the eyes open;The?wave was of statistical significance(P<0.01)in all the five brain regions as the eyes closed.Conclusion:1.Health Qigong Baduanjin can improve the spatial execution ability of patients with mild cognitive impairments.2.The practice of Health Qigong Baiduanjin can improve the power of the?wave and restrain the increase of the?wave,so that the patients with mild cognitive impairments can feel more relaxed in spirit,and reduce the occurrence of nervousness and their neurological function is more stable.3.The power value of each wave is relatively larger and the brain wave is forwarded after practicing Health Qigong Baduanjin.The practice of Health Qigong can activate the frontal lobe activity. |
