%X To evaluate the clinical efficacy of smartphone-assisted self-rehabilitation in patients with frozen shoulder. A single-center, randomized controlled trial. Orthopedic department of a university hospital. A total of 84 patients with frozen shoulder were recruited. Patients were randomly divided into two groups: a smartphone-assisted exercise group (n£¿=£¿42) and a conventional self-exercise group (n£¿=£¿42). The study was performed over three months, during which each group performed home-based rehabilitation. Visual analogue scale for pain and passive shoulder range of motion were assessed at baseline and after 4, 8, and 12£¿weeks of treatment. Technology Acceptance Model¨C2 and Usefulness, Satisfaction, and Ease of Use scores were evaluated in the smartphone group. Initial visual analogue scale for pain of the smartphone group was 6.0£¿¡À£¿2.2 and ended up with 1.8£¿¡À£¿2.5 after 12£¿weeks, whereas the self-exercise group showed 5.8£¿¡À£¿2.3 for the baseline visual analogue scale for pain and 2.2£¿¡À£¿1.7 at the end. Significant time-dependent improvements in all measured values were observed in both groups (all Ps£¿<£¿0.001), but no significant intergroup difference was observed after 4, 8, or 12£¿weeks of treatment. In the smartphone group, Technology Acceptance Model¨C2 and Usefulness, Satisfaction, and Ease of Use scores showed high patient satisfaction with smartphone-assisted exercise. There was no difference between home-based exercise using a smartphone application and a conventional self-exercise program for the treatment of frozen shoulder in terms of visual analogue scale for pain and range of motions
