Acupuncture treatment on idiopathic trigeminal neuralgia: A systematic review protocol

INTRODUCTION: The objective of this systematic review protocol is to provide the methods for evaluating the effectiveness and safety of acupuncture on the treatment of idiopathic trigeminal neuralgia (ITN). METHODS AND ANALYSIS: We will search randomized controlled trials (RCTs) on this subject in 8 electronic databases and they are Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), the Wan-Fang Database, and Chinese Scientific Journal Database (VIP database). Other relevant literatures will be manually searched as a complement. Only RCTs related to acupuncture for ITN in English or Chinese will be included, without limitation of publication types. The risk of bias and trial quality will be assessed by the Cochrane collaboration's tool. All data will be analyzed by RevMan V.5.3.3 statistical software. ETHICS AND DISSEMINATION: Ethical approval is not necessary as this paper does not involve patient data. This protocol will be disseminated by a peer-review journal or conference presentation. TRIAL REGISTRATION NUMBER: PROSPERO CRD42015022173 STRENGTHS AND LIMITATIONS OF THIS STUDY: This systematic review will evaluate the effectivity and safety of acupuncture treatment on idiopathic trigeminal neuralgia. Two authors will perform independently study selection, data extraction and quality assessment, in order to ensure that all included studies are not personal bias. The result of this systematic review may give clinicians more ways to assist patient in relieving trigeminal neuralgia. This shortage of systematic review is due to language barriers, only 2 languages of the trials can be included, other related studies may be missing. Different methods of acupuncture and quality of methodologies may result in essential heterogeneity.
