Subacromial pain syndrome, in the absence of operative pathologies (e.g. rotator cuff tears), can be difficult to treat. Physiotherapy is an important part of this treatment. It is unclear whether there is added benefit to having supervised physiotherapy compared to home exercise programs. In this study, the authors performed a meta-analysis of four randomized controlled trials aimed at answering this question. At a mean of 15 weeks follow-up, they found that on the outcomes of pain, function, and range of motion, there was no significant difference between home and supervised physiotherapy programs.
