BACKGROUND This study will appraise the effectiveness and safety of suprascapular nerve block (SNB) for the treatment of frozen shoulder (FS). METHODS This study will incorporate studies relevant to SNB on FS. Articles will be searched in the electronic databases (MEDLINE, EMBASE, CINAHL, Web of Science, PsycINFO, Cochrane Library, WANGFANG, and CNKI) from inception to the present. In addition, this study will also retrieve conference proceedings and reference lists of included studies. All literature source searches will not be restricted by date and language. The Cochrane Risk of Bias Tool will be utilized to evaluate the quality of retrieved trials. Data will be collected independently by 2 authors. All collected data will be analyzed by RevMan 5.3 software. RESULTS This study will synthesize the most recent published high quality trials on assessing the effectiveness and safety of SNB in treating FS. CONCLUSION The findings of this study will provide a genuine understanding and helpful evidence to determine whether SNB is effective or not in treating FS. STUDY REGISTRATION NUMBER INPLASY202050084.
