Background:Insomnia is a highly widespread sleep disorder in the general population. Electroacupuncture (EA) has been widely received attention as a potential treatment for primary insomnia. However, few previous studies are available to report that EA is a beneficial therapeutic approach to primary insomnia. In addition, there is no critical systematic review or meta-analysis published regarding the effectiveness of this treatment. Here, we provide a protocol to systematically evaluate the efficacy and safety of EA for primary insomnia.Methods:The reference lists of included studies for relevant randomized controlled trials and 8 electronic databases will be systematically searched by 2 review authors in January 2018, including 4 English databases (PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Cumulative Index to Nursing and Allied Health Literature) and 4 Chinese databases (Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, VIP Database, and Wanfang Database). The primary outcomes will be assessed according to the Pittsburgh Sleep Quality Index. Data synthesis will be computed with the use of RevManV5.3 software when a data-analysis is allowed. Methodological quality will be evaluated with the risk of bias according to Cochrane Handbook.Results:This study will provide a high-quality synthesis of current evidence of EA for primary insomnia.Conclusion:The conclusion of this systematic review will provide evidence to judge whether EA is an effective therapeutic intervention for patient with primary insomnia.
