Effect Of Health Qigong Baduanjin On Executive Function And Physical Function In Patients With Mild Cognitive Impairment

Objective: The patients with mild cognitive impairment were treated with Health Qigong Baduanjin training for 16 weeks.Using executive function evaluation tasks,Chinese mini-physical performance test(CM-PPT)and Static balance ability test to observe the changes in executive function and physical function in the patients before and after the intervention.The effect of Health Qigong Baduanjin on executive function and physical function in patients with mild cognitive impairment will be investigated in this study.Subjects and Methods: A total of 30 patients with mild cognitive impairment aged 60-70 years old from Yangchun garden,Heping district,Shenyang city and their surrounding communities were selected as subjects.Patients were randomly grouped.Among them,15 were in the control group and 15 in the experimental group.The control group did not perform any exercise.The experimental group performed 16-week Health Qigong Baduanjin exercises.Result 20 cases completed the experiment.Subjects were tested for executive function,physical function and static balance ability before and after 16 weeks' intervention.Three sub-functions of inhibition function,shifting function,and the updating function of the executive function were tested by using the flanker task,the more-odd shifting task,and the 2-back task.Physical function was tested using the Chinese Mini-physcial performance test(CM-PPT).Static balance ability was tested using the METITUR system.SPSS22.0 statistical software was used to statistically analyze the research data.The intragroup differences were significantly analyzed by paired sample t test.Independent sample t-test was used to test the difference between groups.When the P value was less than 0.05,the difference was statistically significant.The results were expressed as ?x±s.Results: It was observed that after 16 weeks of Health Qigong Baduanjin exercise,(1)Compared with pre-intervention,the indexes of executive function were significantly improved except for the accuracy of the flanker task in the experimental group(P <0.05 or P <0.01).Compared with control group,the reaction time of flanker task,more-odd shifting task and 2-back task in the experimental group were significantly shorter(P<0.05 or P<0.01),and the accuracy of more-odd shifting task and 2-back task in the experimental group were significantly improved(P<0.05).(2)Physical function: Compared with the pre-intervention,the indexes of physical function were significantly increased except for the standing balance and 6m walking scores in the experimental group(P<0.05 or P<0.01).Compared with control group,the indexes were significantly improved except for the standing balance and 6m walking scores in the experimental group(P<0.01).(3)Compared the indexes(Vx,Vy,and velocity moments)of static balance ability before and after the intervention,Vx,Vy,and velocity moments in the experimental group were significantly improved in the state of two foot open eye standing(P<0.01);Vx,Vy,and velocity moments were significantly improved in the state of two foot close eye standing(P<0.01).Vx,Vy,and velocity moments were significantly improved in the state of semi tandem standing(P<0.01);the indexes were significantly improved except for the velocity moments in the state of tandem standing(P<0.01);the indexes were significantly improved except for the velocity moment in the state of left foot eye open standing(P<0.01);Vx,Vy,and velocity moments were significantly improved in the state of right foot eye open standing(P<0.01).Compared with the indexes in the control group,Vx and Vy in the state of two foot eye open standing,Vy in the state of two foot eye close standing,Vx in the state of semi tandem standing,Vx in the state of tandem standing,Vx in the state of left foot eye open standing,and Vy in the state of right foot eye open standing were all significantly improved in the experimental group(P<0.05 or P<0.01).Conclusion:(1)Health Qigong Baduanjin exercise improved the inhibition function,shifting function and updating function of patients with mild cognitive impairment,and significantly improved the executive function of patients with mild cognitive impairment.(2)Health Qigong Baduanjin exercise has a significant effect on the physical function of patients with mild cognitive impairment.(3)Health Qigong Baduanjin exercise can improve the static balance ability of patients with mild cognitive impairment.
