Introduction: Tension-type headache (TTH) refers to a type of functionalism disease, which is commonly characterized by recurrent headaches of mild to moderate intensity, bilateral location, pressing or tightening quality, and no aggravation by routine physical activity. Has significantly impacts on people's work and life. Ear acupuncture as a traditional Chinese therapy, showing several advantages (e.g., safety, economy, and less side effects), has been extensively used to treat TTH. However, its curative effect is supported by limited evidence. Accordingly, the present study aims to comprehensively assess the reliability of ear acupuncture in TTH.
Methods and analysis: The study will conduct a systematic review and meta-analysis. Seven databases, including the Embase, Cochrane Library, Pubmed, SinoMed, CNKI, VIP, and Wanfang Data, will be searched using predefined search terms to identify relevant studies. The primary outcomes will be the pain intensity, the pain frequency and the impact of headache. The methodological quality of the included studies will be assessed with a previously established checklist. The Cochrane Collaboration's bias risk tool will be used for assessing the bias of included RCTs. Stata 17.0 software is used for meta-analysis.
