What this Trial Is About
The trial investigates the effects of reverse total shoulder arthroplasty on shoulder movement and function in adults who have undergone this surgery about two years earlier. This procedure is used to improve shoulder stability and mobility in patients with osteoarthritis, especially when deep shoulder muscles are damaged. The study aims to compare the operated shoulder's movement with the non-operated side to better understand long-term outcomes. Participants have previously received reverse total shoulder arthroplasty performed by a specific surgeon and will undergo imaging exams called EOS scans. These scans take X-rays of both shoulders in various arm positions to evaluate shoulder angles. Additionally, participants will complete questionnaires assessing pain and shoulder function. The study focuses on measurements taken one month after the assessment visit. During the study, participants will have six X-ray images taken while standing with their arm at 0°, 45°, and 90° elevations. They will also fill out two questionnaires about pain and daily shoulder function. The research team will measure shoulder movement coordination and functional scores on both shoulders. The total participation time includes the imaging and questionnaire completion at the study visit, with follow-up outcomes assessed one month later.
