Effects Of Aerobic Exercise On Blood Pressure Level And Individual Activity Ability In The Elderly With Stroke And Hypertension

Objective The study attempts to investigate the effects of adding aerobic exercise to the conventional rehabilitation therapy on the blood pressure level,activities of daily living,limb motor function and balance ability in elderly stroke patients with hypertension,and to compare with the differences between the supervised and unsupervised target intensity aerobic exercise in blood pressure,daily living activities,limb motor function and balance ability in elderly stroke patients with hypertension,and to provide a more effective rehabilitation treatment program for the clinic.Methods A total of 48 elderly stroke patients with hypertension were randomly divided into control group(conventional rehabilitation group),conventional rehabilitation group+unsupervised treadmill group(unsupervised treadmill group)and conventional rehabilitation group+supervised treadmill group(supervised treadmill group),with 16 cases in each group and finally 45 subjects completed the trial.The control group was given conventional rehabilitation training;The unsupervised treadmill group was on the basis of conventional rehabilitation training,and carried out not supervised the medium intensity treadmill training;The supervised treadmill group was on the basis of conventional rehabilitation training,and carried out supervised the medium intensity treadmill training,which needed a professional therapist.The patients both the supervised treadmill group and the unsupervised treadmill group were participated in the intervention at the frequency of 30 min per session,one session every day,five days per week,and a total of 6 weeks of treadmill training intervention.Before and after six-weeks intervention,using the dynamic blood pressure indicators,the Modified Barthel index(MBI)scale,the Berg Balance Scale(BBS)and “Brunnstrom,s Recovery Stages of Stroke” as the measures.The data were analyzed by SPSS20.0 statistical software.Levels of statistic significant were set as p < 0.05.Results 1.24 Hours Dynamic Blood Pressure Indicators After six-weeks the intervention,the 24 h mean systolic blood pressure and 24 h mean diastolic blood pressure indexes,and night systolic blood pressure and diastolic blood pressure indexes in supervised treadmill group were more obvious decreased than that of the control group and the unsupervised treadmill group,the difference was statistically significant(p<0.05).Before and after 6 weeks the intervention,the 24-hour dynamic blood pressure monitoring indexes of the unsupervised treadmill group and the control group decreased,however,there was no difference between groups(p>0.05).2.Activities of Daily Living Activities After six-weeks of intervention,the MBI scale of the supervised treadmill group was significantly higher than that of the control group and the unsupervised treadmill group,the difference was statistically significant(p<0.05);Although the MBI scale scores inthe unsupervised treadmill group and the control group were also improved,there was no difference between groups(p>0.05).3.Balance Ability The results of the Berg Balance Scale(BBS)in both the supervised treadmill group and the unsupervised treadmill group was significantly higher than that before the intervention(p<0.05),but there was no significant difference between the two groups.The balance ability of the supervision treadmill group and the unsupervised treadmill group was significantly higher than that of the control group(p<0.05),and the difference was statistically significant.4.Limb Movement Function Before and after six-weeks intervention,the Brunnstrom,s Recovery Stages of Stroke scores were changed in the three groups,but there was no significant difference(p>0.05).Conclusion 1.For elderly stroke patients with hypertension that obvious increase in night systolic blood pressure and the pulse pressure difference,adding the supervised treadmill exercise to the conventional rehabilitation and drug therapy can more effectively reduce the night systolic blood pressure and the pulse pressure difference. 2.Adding aerobic exercise to conventional rehabilitation therapy can more effectively improve the balance ability of elderly stroke patients with hypertension. 3.Adding aerobic exercise under the supervision of professional therapists to the conventional rehabilitation therapy can effectively improve the daily living activities of elderly stroke patients with hypertension.
