Electromyographic biofeedback (EMG-BF) has been applied to treat different types of peripheral nerve injuries (PNI). However, despite the clinical practice widespread use its evidence is controversial. With the objective of summarize the available evidence on the electromyographic biofeedback effectiveness and efficacy to help motor function recovery after PNI an integrative review was performed. A secondary objective was to identify the conceptual framework and strategies of EMG-BF intervention, and the quality of technical description of EMG-BF procedures. To conduct this integrative review a systematic search of the literature was performed between October 2013 and July 2018, in PUBMED, ISI and COCHRANE databases for EMG-BF original studies in PNI patients of any etiology, in English, Portuguese, Spanish or French, published after 1990. Exclusion criteria were poor description of EMG-BF treatment, associated treatment that could impair EMG-BF effect, inclusion of non-PNI individuals and case studies design. The PEDro scale was used to evaluate study quality of randomized clinical trials (RCTs) included. This resulted in 71 potential articles enrolled to full reading, although only nine matched the inclusion criteria. PNI included facial paralysis, acute sciatic inflammation and carpal tunnel syndrome. The average quality score of the included RCTs was five, corresponding to low methodological quality. Due to the small number of included articles, low quality studies and heterogeneity of interventions, outcomes and population we concluded that there is limited evidence of EMG-BF effectiveness and efficacy for motor function recovery in PNI patients.

周围神经损伤后运动功能恢复中的肌电生物反馈：文献综述。

肌电生物反馈（EMG-BF）已用于治疗不同类型的周围神经损伤（PNI）。然而，尽管临床实践被广泛使用，其证据仍存在争议。为了总结有关肌电图生物反馈有效性和功效的可用证据，以帮助PNI后恢复运动功能，进行了综合评估。次要目标是确定EMG-BF干预的概念框架和策略，以及EMG-BF程序的技术描述质量。为了进行这项综合性综述，我们于2013年10月至2018年7月之间在PUBMED，ISI和COCHRANE数据库中进行了文献检索的系统检索，以针对任何病因的PNI患者进行EMG-BF原始研究，以英语，葡萄牙语，西班牙语或法语出版1990年以后。排除标准对EMG-BF治疗，可能损害EMG-BF效果的相关治疗，非PNI个体的纳入以及案例研究设计的描述不充分。PEDro量表用于评估随机临床试验（RCT）的研究质量。尽管只有9篇符合入选标准，但仍有71篇潜在的文章入读。PNI包括面瘫，急性坐骨炎和腕管综合症。纳入的RCT的平均质量得分为5，这与方法学质量较低相对应。由于收录的文章数量少，研究质量低下，干预措施，结果和人群的异质性，我们得出结论，对于PNI患者，EMG-BF对运动功能恢复的有效性和功效的证据有限。
