Rehabilitation following anterior cruciate ligament (ACL) reconstruction surgery is essential to regain functionality and return to previous activity level. Electromyographic biofeedback may be an effective intervention for rehabilitation of patients following ACL surgery.
To synthesize the available evidence on the effect of electromyographic biofeedback in the treatment of quadriceps strength following ACL surgery.
Systematic review with meta-analysis.
PubMed, EMBASE, CENTRAL and Epistemonikos were searched.
Randomized clinical trials with patients undergoing ACL reconstruction surgery comparing biofeedback with a standard rehabilitation control group.
Two authors selected articles and performed data extraction. The analysed outcomes were strength, function, pain, knee extension and balance. The risk of bias of individual studies was assessed using the Cochrane Risk of Bias Tool. Results were combined through random-effects meta-analysis, reporting mean differences.
Eight articles were included in the qualitative analysis, and four articles were included in the quantitative analysis. The interventions lasted between 4 and 12 weeks. Three studies evaluated the effect of biofeedback on quadriceps strength; of these, two studies showed a significant difference in favour of the biofeedback group. In addition, biofeedback was found to improve knee extension [standardized mean difference - 1.3, 95% confidence interval (CI) - 1.74 to -0.86] and balance (one study). There was no significant difference in Lysholm score (mean difference -6.21, 95% CI -17.51 to 5.08; I =59%) or pain between the biofeedback group and the control group.
Electromyographic biofeedback in knee rehabilitation could be useful following ACL reconstruction surgery.

前交叉韧带（ACL）重建手术后的康复对于恢复功能和重返之前的活动水平至关重要。肌电图生物反馈可能是 ACL 手术后康复患者的有效干预措施。
综合现有证据评估肌电图生物反馈在 ACL 手术后治疗股四头肌力量的效果。
系统评价和荟萃分析。
PubMed、EMBASE、CENTRAL 和 Epistemonikos 进行检索。
比较 ACL 重建手术后接受生物反馈与标准康复对照组的随机临床试验。
两位作者选择文章并进行数据提取。分析的结果是力量、功能、疼痛、膝关节伸展和平衡。使用 Cochrane 偏倚风险工具评估单个研究的偏倚风险。结果通过随机效应荟萃分析进行合并，报告平均差异。
8 篇文章进行了定性分析，4 篇文章进行了定量分析。干预时间从 4 周到 12 周不等。三项研究评估了生物反馈对股四头肌力量的影响；其中两项研究表明生物反馈组有显著差异。此外，生物反馈被发现可以改善膝关节伸展[标准化均数差 -1.3，95%置信区间（CI）-1.74 至 -0.86]和平衡（一项研究）。生物反馈组和对照组在 Lysholm 评分（平均差 -6.21，95%CI -17.51 至 5.08；I =59%）或疼痛方面没有显著差异。
肌电图生物反馈在 ACL 重建手术后的膝关节康复中可能有用。
