Efficacy of hydrodistension for frozen shoulder: A systematic review and meta-analysis

Abstract

Background: The aim of this study was to provide comprehensive and reliable evidence for the treatment of pain and motor function in patients with frozen shoulder (FS) with hydrodistension Methods: The research including randomized controlled trials (RCTs) for FS that compared hydrodistension with routine treatments to controls was searched and screened in the PubMed, Library of congress, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, China Science and Technology Journal Database. Constant-Murley score (CMS) for shoulder function and visual analog scale (VAS) for pain must be assessed. RevMan 5.3 software was used to evaluate the bias and quality of the included studies. Results: We found that analgesic effects (MD: −1.07; 95% CI: −1.94 to −0.20; P < .00001; I 2 = 99%) and function (MD: 8.54; 95% CI: 3.35 to 13.71; P < .00001; I 2 = 97%) were better in the groups where hydrodistension plus routine treatments were used to treat FS compared to other interventions. Conclusion: The result suggests that hydrodistension is of great clinical significance in alleviating pain and improving function to patients with FS.
