Abstract:
ObjectiveTo estimate the total effect size and the proportion of contextual effect (PCE) of non-surgical treatments for rotator cuff injury. MethodsRandomized controlled trial (RCT) on non-surgical treatments for rotator cuff injuries was retrieved from PubMed, Embase, Cochrane Library, Web of Science, CINAHL, CNKI, and Wanfang Data from the establishment to October, 2020. Two researchers conducted independent literature screening, data extraction and quality evaluation, and used STATA 15.0 software for meta-analyses. ResultsForty studies involving 2 976 participants were included. The total PCE of pain was 0.61 (95% CI 0.54 to 0.69). PCE of treatments from the largest to the smallest were corticosteroid injection, extracorporeal shockwave therapy, oral non-steroidal anti-inflammatory drugs (NSAIDs), manual therapy, hyaluronic acid injection therapy, platelet-rich plasma injection therapy, laser therapy, NSAIDs injection therapy, and acupuncture therapy. Total PCE for function and range of motion was 0.69 (95% CI 0.61 to 0.77) and 0.62 (95% CI 0.48 to 0.81), respectively. Blinding, studies in developed countries, and longer courses of treatment increased the PCE of pain. ConclusionUp to 61% of PCE for the non-surgical treatments for rotator cuff injuries means instable research. A higher proportion of PCE may be the cause of inconsistencies between clinical practice and clinical research conclusions.
