Background: Shoulder impingement syndrome is a common musculoskeletal condition in which exercise therapy is widely used; however, its effectiveness depends largely on patient adherence. Tele-rehabilitation strategies have been proposed to improve adherence in home exercise programs. Objectives: To compare the effects of a home coaching–based home exercise program (HCHEP) with a standard home exercise program (HEP) on exercise adherence, pain intensity, and shoulder disability. Design: A randomized controlled trial. Methods: Thirty participants with shoulder impingement syndrome were randomly assigned to either the HCHEP group (n=15) or the HEP group (n=15). Both groups performed a standardized home exercise program for 6 weeks. The HCHEP group additionally received structured tele-recovery coaching sessions focusing on feedback, goal setting, and problem-solving strategies. Outcomes included exercise adherence (%), pain intensity (Numeric Rating Scale), and shoulder disability (SPADI), assessed at baseline, post-intervention (6 weeks), and follow-up (12 weeks). Linear mixed models and repeated measures ANOVA were used for statistical analysis. Results: The HCHEP group showed significantly higher adherence and greater improvements in pain and shoulder disability compared with the HEP group (P<0.01). Significant interactions (group, time) were observed for all outcomes. Conclusion: Tele-recovery coaching enhances adherence and improves clinical outcomes in individuals with shoulder impingement syndrome.
