Electrical stimulation (ES) is widely used to strengthen muscles following ligament and meniscal injuries. The aim of this study was to evaluate the effectiveness of ES for rehabilitation after soft tissue injuries of the knee treated surgically or conservatively.
Systematic review at the Brazilian Cochrane Center.
We searched the Cochrane Central Register of Controlled Trials (2010, Issue 12), Medline (Medical Analysis and Retrieval System Online) via PubMed (1966 to December 2010), Embase (Excerpta Medica database, 1980 to December 2010), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde, 1982 to December 2010), and PEDro (Physiotherapy Evidence Database, 1929 to December 2010). The studies included were randomized controlled trials using ES to increase muscle strength for rehabilitation of patients with soft tissue injuries of the knee. Two authors independently evaluated studies for inclusion and performed data extraction and methodological quality assessment.
Seventeen studies evaluating ES after anterior cruciate ligament reconstruction and two studies evaluating ES after meniscectomy were included. There was a statistically significant improvement in quadriceps strength through ES (mean difference, MD: -32.7; 95% confidence interval, CI: -39.92 to -25.48; n = 56) and in functional outcomes (MD -7; -12.78 to -1.22; n = 43) six to eight weeks after surgical reconstruction of the anterior cruciate ligament.
There is evidence that ES coupled with conventional rehabilitation exercises may be effective in improving muscle strength and function two months after surgery.
电刺激（ES）被广泛用于韧带和半月板损伤后增强肌肉力量。本研究旨在评估电刺激对手术或保守治疗的膝关节软组织损伤后康复的有效性。
巴西考科蓝中心的系统评价。
我们检索了考科蓝对照试验中心注册库（2010年第12期）、通过PubMed检索的Medline（医学分析与检索系统在线，1966年至2010年12月）、Embase（医学文摘数据库，1980年至2010年12月）、Lilacs（拉丁美洲和加勒比卫生科学文献，1982年至2010年12月）以及PEDro（物理治疗证据数据库，1929年至2010年12月）。纳入的研究为使用电刺激增加膝关节软组织损伤患者肌肉力量以进行康复的随机对照试验。两位作者独立评估纳入研究，并进行数据提取和方法学质量评估。
纳入了17项评估前交叉韧带重建后电刺激的研究以及2项评估半月板切除术后电刺激的研究。在前交叉韧带手术重建后6至8周，通过电刺激，股四头肌力量有统计学意义的改善（平均差，MD：-32.7；95%置信区间，CI：-39.92至-25.48；n = 56），功能结局也有改善（MD -7；-12.78至-1.22；n = 43）。
有证据表明，电刺激与传统康复锻炼相结合可能在术后两个月有效改善肌肉力量和功能。
