Effect of blood flow restriction training under different intensities combined with low-intensity resistance training on motor function in elderly stroke patients with frailty
目的 探讨不同强度血流限制训练(BFRT)联合低强度抗阻训练(LIRT)对老年缺血性脑卒中伴衰弱患者运动功能的影响. 方法 2024年8月至2025年8月,华北理工大学附属医院200例缺血性脑卒中伴衰弱老年患者,随机分为对照组、观察1组、观察2组和观察3组,各50例.对照组采用30%1RM抗阻训练;在此基础上,观察1～3组均分别接受40%动脉闭塞压(AOP)、50%AOP和60%AOP的BFRT,共8周.训练前,训练4周和8周后,采用Fugl-Meyer评定量表上肢部分(FMA-UE)和下肢部分(FMA-LE)、握力测试、10米步行测试(10MWT)和Berg平衡量表(BBS)评估运动功能,采用Fried衰弱表型(FFP)评估衰弱状态,采用改良Ashworth量表(MAS)评估肌张力,测量血压和静息心率. 结果 4组各脱落1例.FMA-UE评分、FMA-LE评分、双手握力、10MWT和BBS评分的组内、组间和交互效应均显著(F>2.745,P<0.05).训练4周后,观察1～3组的各指标均高于对照组(P<0.05).训练8周后,观察3组FMA-UE、FMA-LE、左右手握力和BBS评分均优于观察1～2组(P<0.05),10MWT优于观察1组(P<0.05).FFP评分的组内效应显著(F=688.360,P<0.001),组间效应和交互效应均不显著(P>0.05).MAS评分的组内效应显著(F=7.171,P=0.008),组间效应和交互效应均不显著(P>0.05).收缩压、舒张压和静息心率的组内、组间和交互效应均不显著(P>0.05). 结论 BFRT联合LIRT可安全有效地改善老年缺血性脑卒中衰弱患者的肢体运动功能、握力、步行与平衡能力,60%AOP效果可能更优.
Objective To explore the effect of blood flow restriction training(BFRT)under different intensities combined with low-intensity resistance training(LIRT)on motor function in stroke patients with frailty. Methods From August,2024 to August,2025,200 elderly ischemic stroke patients with frailty from Affiliated Hospital,North China University of Science and Technology were randomized into control group and observation groups 1,2 and 3,with 50 cases in each group.All the groups received 30%1RM resistance training.In addition,the ob-servation groups received BFRT of 40%,50%and 60%arterial occlusion pressure(AOP),respectively.Before training,and four and eight weeks after training,their motor function was evaluated with Fugl-Meyer Assess-ment-Upper Extremities(FMA-UE)and Fugl-Meyer Assessment-Lower Extremities(FMA-LE),grip strength,10-Metre Walk Test(10MWT)and Berg Balance Scale(BBS);Fried Frailty Phenotype(FFP)was used to assess frailty status;and the score of modified Ashworth Scale(MAS),blood pressure and resting heart rate were record-ed. Results One case dropped out in each group.For the scores of FMA-UE and FMA-LE,the grip strength of both hands,the time of 10MWT and the score of BBS,the main effects of group and time,and interaction effect were all sig-nificant(F>2.745,P<0.05);four weeks after training,the above indexes were better in the observation groups than in the control group(P<0.05);eight weeks after training,the scores of FMA-UE and FMA-LE,the grip strength of both hand and the score of BBS were better in the observation group 3 than in the observation groups 1 and 2(P<0.05),and the time of 10MWT was better in the observation group 3 than in the observation group 1(P<0.05).For the score of FFP,the main effect of group was significant(F=688.360,P<0.001),however,the effects of time and interaction were not significant(P>0.05).For the score of MAS,the main effect of group was significant(F=7.171,P=0.008),however,the effects of time and interaction were not significant(P>0.05).For the blood pressure and resting heart rate,the main effects of group and time,and interaction effect were not significant(P>0.05). Conclusion BFRT under different intensities combined with LIRT can safely improve the motor function,grip strength,walking ability in elderly stroke patients,and 60%AOP may be more effective.
