Effect of Smartphone Application-Supported Self-Rehabilitation for Frozen Shoulder: A prospective randomized control study

Not Applicable

Completed

Conditions: Diseases of the musculo-skeletal system and connective tissue

Registration Number: KCT0002682

Lead Sponsor: Seoul National University Hospital

Brief Summary: o follow-up loss occurred during the study and data collection was complete. Baseline VAS scores in the smartphone and conventional treatment groups were not significantly different; scores exhibited continuous improvements throughout the follow-up period in both groups (Table 2 and Fig. 3), and both showed significant reductions in VAS scores between baseline and final follow-up after treatment for 3 months (both Ps < 0.001). No intergroup difference was observed between VAS scores after 4, 8, or 12 weeks of treatment by RM ANOVA (p = 0.750). With regard to secondary outcomes, the ROM (forward flexion, abduction, external rotation, and internal rotation) improved over time in both groups, and intergroup differences were non-significant (Table 2 and Fig. 4). Furthermore, RM ANOVA showed forward flexion (p = 0.481), abduction (p = 0.911), external rotation (p = 0.283), and internal rotation (p = 0.276) were not significantly different in the two groups at any time point. Five patients, that is, 3 in the smartphone group and 2 in the self-exercise group received an intra-articular steroid injection during follow-up, but this did not constitute a significantly intergroup difference (P = 0.645). The results of the usability questionnaires are summarized in Table 3. In the smartphone group, TAM-2 and USE scores indicated patients were highly satisfied with the smartphone application.
