Background

Blood flow restriction (BFR) is an effective clinical intervention used to increase strength in healthy individuals. However, its effects on pain and function in individuals with knee pain are unknown.

Objective

To determine the effectiveness of adding BFR to resistance exercise for pain relief and improvement of function in patients with knee pain.

Methods

Systematic review with meta-analysis of randomized clinical trials. Medline, Central, Embase, PEDro, Lilacs, CINAHL, SPORTDiscus, and Web of Science databases were searched from inception to May 2019. Randomized clinical trials that compared resistance exercise with or without BFR to treat knee pain and function in individuals older than 18 years of age with knee pain were included.

Results

Eight randomized clinical trials met the eligibility criteria and for the quantitative synthesis, five studies were included. The pooled standardized mean difference (SMD) estimate showed that resistance exercises with BFR was not more effective than resistance exercises for reducing pain (SMD: −0.37 cm, 95% CI = −0.93, 0.19) and improving knee function (SMD = −0.23 points, 95% CI = −0.71, 0.26) in patients with knee pain.

Conclusion

In the short term, there is low quality of evidence that resistance exercise with BFR does not provide significant differences in pain relief and knee function compared to resistance exercises in patients with knee pain.

在膝关节疼痛患者的抵抗运动中增加血流限制:系统评价和荟萃分析。

背景

血流限制(BFR)是一种有效的临床干预措施,可用于增加健康个体的力量。然而,其对膝痛患者的疼痛和功能的影响尚不清楚。

目的

确定在抵抗运动中添加BFR对缓解膝关节疼痛患者的疼痛和改善功能的有效性。

方法

对随机临床试验进行荟萃分析的系统评价。从开始到2019年5月,对Medline,Central,Embase,PEDro,Lillacs,CINAHL,SPORTDiscus和Web of Science数据库进行了搜索。随机临床试验比较了18岁以上有或无BFR的抵抗运动治疗膝盖疼痛和功能的患者包括膝盖疼痛的年龄。

结果

八项随机临床试验符合入选标准,为进行定量合成,纳入了五项研究。汇总的标准化平均差异(SMD)估计表明,BFR抵抗运动并不比抵抗运动对减轻疼痛(SMD:-0.37 cm,95%CI = -0.93,0.19)和改善膝盖功能(SMD = -0.23)更有效。膝痛患者的平均得分为95%CI = -0.71、0.26)

结论

短期内,证据质量低下,与膝关节疼痛患者的抵抗运动相比,BFR抵抗运动与疼痛缓解和膝关节功能没有明显差异。
