Introduction Previous systematic reviews have identified the multiple factors impacting on the prognosis of shoulder pain. However, the typical clinical course of subacromial shoulder pain remains unclear. The aim of this systematic review is to assess the clinical course of pain and disability in patients with subacromial shoulder pain.
Method and analysis We will systematically search electronic databases (Medline, Embase and AMED (via Ovid), Web of Science, Cochrane Library and Scopus) from the date of inception to 28 February 2018 for randomised controlled trials (RCTs) and observational studies with patients with subacromial shoulder pain. We will follow patient groups measured with pain and disabilities with no intervention or usual care treatment. Two reviewers will extract the data, and assess the risk of bias within included studies. We will use the Cochrane Risk of Bias tool for RCTs, and a methodological quality assessment tool for observational studies. We will perform meta-analyses for changes in pain and disability scores for each group (usual care and no intervention) at different time categories (up to 6 weeks, 6–12 weeks, 12–26 weeks or more). If there are 10 or more studies, we will perform a meta-regression for each planned analysis. The outcomes of the included studies will be described individually if the above statistical methods are not possible. Findings from this review will be of interest to clinicians and researchers, and will describe the expected clinical course of subacromial shoulder pain. This study may indicate the potential differences between the clinical courses of pain and disability over time.
Ethics and dissemination This review will not gather original data, hence ethical approval is not required. The results of this systematic review will be published in a peer-reviewed journal and presented at a scientific conference.
