Abstract:
(1) Objective: To examine the effects of blood flow restriction (BFR) training on muscle strength, cross-sectional area and knee-related function in patients selected for anterior cruciate ligament reconstruction (ACLR). (2) Methods: A literature search was conducted in PubMed, PEDro, Cochrane Library, Web of Science, SCOPUS, and ProQuest databases until 20 May 2024. Controlled clinical trials comparing the effects of BFR training with unrestricted training in patients before or after ACLR were selected. The GRADE approach was used to assess the degree of certainty for each meta-analysis. (3) Results: Ten studies were included (n = 287 participants). Standardized mean differences in favor of BFR training applied postoperatively were observed in knee extensor (SMD = 0.79; 95% CI = 0.06 to 1.52; I2: 68%) and flexor isokinetic strength (SMD = 0.53; 95% CI = 0.04 to 1.01; I2: 0%), and quadriceps cross-sectional area (SMD = 0.76; 95% CI = 0.27 to 1.26; I2: 0%). No changes were found in knee extensor isometric strength and knee-related function. The degree of certainty according to the GRADE was very low. (4) Conclusions: Very low degree of certainty suggests that BFR training provides additional benefits to unrestricted training on isokinetic strength and quadriceps cross-sectional area in patients undergoing ACLR.
摘要:
(1)目的:探讨血流受限(BFR)训练对肌力的影响,选择前交叉韧带重建(ACLR)的患者的横截面积和膝关节相关功能。(2)方法:在PubMed进行文献检索,PEDro,科克伦图书馆,WebofScience,Scopus,和ProQuest数据库,直到2024年5月20日。选择在ACLR之前或之后比较BFR训练与无限制训练对患者的影响的对照临床试验。GRADE方法用于评估每个荟萃分析的确定性程度。(3)结果:纳入10项研究(n=287名参与者)。在膝关节伸肌(SMD=0.79;95%CI=0.06至1.52;I2:68%)和屈肌等速肌力(SMD=0.53;95%CI=0.04至1.01;I2:0%)中观察到了有利于术后BFR训练的标准化平均差异,股四头肌横截面积(SMD=0.76;95%CI=0.27至1.26;I2:0%)。没有发现膝关节伸肌等轴力和膝关节相关功能的变化。根据等级的确定程度非常低。(4)结论:非常低的确定性表明,BFR训练为接受ACLR的患者的等速肌力和股四头肌横截面积的无限制训练提供了额外的好处。
