Sequential Changes in Scapular Range of Motion After An Intervention Using the KOJI AWARENESS Original “Wall Angel Slider” Exercise

Context : We aimed to evaluate the sequential changes in the scapular range of motion (ROM) after an intervention using the KOJI AWARENESS Original Wall Angel Slider exercise in which reverse motion is applied. Design : This study used a single-group, pretest–posttest design to evaluate changes in scapular ROM following an intervention. Methods : Participants (n = 54) underwent a 2-week intervention in this study. Scapular mobility was screened using the KOJI AWARENESS Self-Screening Scapula Mobility test, and participants with scapular mobility restrictions were recruited (n = 48). The participants performed the Wall Angel Slider exercise involving reverse motion tasks with dynamic sliding movements against a wall. They performed 3 sets of 8 repetitions for 6 sessions in 2 weeks, and adherence to the exercise regimen was monitored using a checklist. The scapular upward rotation and glenohumeral joint external rotation ROM were measured before the intervention, immediately after the first session, and after 2 weeks of the intervention. Results : The participants exhibited significant improvements in scapular upward rotation and glenohumeral external rotation ROM after the first session of an intervention using the Wall Angel Slider exercise and after 2 weeks of the intervention. Conclusion : The KOJI AWARENESS Original Wall Angel Slider exercise effectively improves scapular upward rotation and glenohumeral joint external rotation ROM over a 2-week intervention period, suggesting its potential utility in enhancing scapular mobility and function in clinical practice.
