The Efficacy Of Low Load Blood Flow Restriction Training On Balance Function In Patients With Posterior Circulation Ischaemic Stroke

Objective:To observe the efficacy of blood flow restriction combined with low load resistance training on balance function in patients with posterior circulation ischaemic stroke.Methods:According to the nadir criteria of this study,28 patients with unilateral posterior circulation ischemic stroke within 2 months of first onset who were hospitalized in the Department of Rehabilitation Medicine of the First Hospital of Shanxi Medical University from October 2019 to February 2023 were selected and were divided into a control group and a test group according to the random number table method,with 14 patients in each group.Patients in the control group were given conventional rehabilitation training and low-load resistance training,while patients in the trial group were given conventional rehabilitation training and low-load blood flow restriction training.Patients in both groups underwent balance assessment before treatment,after 3weeks of treatment and after 6 weeks of treatment.The assessment methods included static stability and multi-axis proprioceptive assessment with the aid of a Pro-Kin254 P dynamic-static balance machine,Berg Balance Scale(BBS)score and the Timed ‘Up and Go’ Test(TUGT).Results:There was no statistically significant difference between the general information of the control group and the test group from the pre-treatment indicators(P > 0.05).After 3 weeks of treatment,there was no statistically significant difference in the static stability score(length of movement,area of movement,standard deviation front-toback,standard deviation left-to-right),multi-axis proprioceptive score(average track error,average force variation,stability index),BBS score and time spent on the TUGT between the test group and the control group(P >0.05).After 6 weeks of treatment,the test group had better static stability scores,multi-axis proprioceptive scores,BBS scores and time spent on the TUGT than the control group,and the difference was statistically significant(P < 0.05).In both the test and control groups,there were statistically significant differences in static stability scores,multi-axis proprioception scores,BBS scores and time spent on the TUGT between the three time points(P < 0.05),and balance function was significantly better in patients with posterior circulation ischaemic stroke after 6 weeks of treatment compared with pre-treatment and after 3 weeks of treatment(P < 0.05),and after 3 weeks of treatment The balance function of patients with ischaemic stroke was better than before treatment(P < 0.05).Conclusion:Low-load blood flow restriction training significantly improves dynamic and static balance and improves walking stability in posterior circulation stroke patients.
