Wrist ankle acupuncture in the treatment of acute lumbar sprain A protocol for systematic review and meta-analysis

Background: Acute lumbar sprain (ALS) frequently occurs in the young and middle-aged people, causing great harm to people's quality of life. The systematic review program was designed to describe a meta-analysis to evaluate the efficacy and safety of wrist-ankle acupuncture (WAA) in treating patients with ALS. Methods and analysis: Our systematic review will search electronically and manually for WAA treatments for ALS by August, 2020, regardless of publication status and language. Databases include: MEDLINE, PubMed, EMBASE, Springer, Web of Science, Cochrane Library, WHO International Clinical Trial Registration Platform (ICTRP), Chinese Medicine Database (TCMD), China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), China Science Journal Database (VIP), and Wanfang Database. Other sources of information, including bibliographies and meeting minutes for identified publications, will also be searched. Manually search for grey literature, including unpublished conference articles. Any clinical randomized controlled trials related to WAA treatments for ALS, regardless of publication status and language limitations, will be included in the study. Study selection, data extraction, and research quality assessment will be done independently by 2 researchers. The primary outcome included the effective rate and visual analogue scale (VAS) or other validated scales used to relieve pain after the treatment. If possible, meta-analysis will be performed using RevMan V.5.3 statistical software. If it is not suitable for meta-analysis, a descriptive analysis or subgroup analysis is performed. Results: This study will provide a comprehensive review and evaluation of the available evidence for the treatment of ALS using WAA. Conclusion: This study will provide new evidence to evaluate the effectiveness and side effects of WAA on ALS. Because the data is not personalized, no formal ethical approval is required.
