Comparing Telerehabilitation and Home-based Exercise for Shoulder Disorders: A Systematic Review and Meta-analysis

Objective: This systematic review and meta-analysis aimed to quantitatively compare the effects of telerehabilitation and home-based exercise for shoulder disorders. Data Sources: We conducted a search for eligible studies in PubMed, EMBASE, Web of Science, Cochrane Library, and MEDLINE databases following Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. Study Selection: Independent reviewers selected randomized controlled trials that compared the effects of telerehabilitation and home-based exercise in individuals with shoulder disorders. Data Extraction: Two reviewers independently conducted data extraction and assessed the risk of bias using the Cochrane Risk of Bias tool. Data Synthesis: A total of 7 studies with 508 participants were included. Compared with home-based exercise, telerehabilitation showed superior improvements in range of motion (flexion: standardized mean difference [SMD] 0.35, 95% confidence interval [CI] 0.14 to 0.56; abduction: SMD 0.37, 95% CI 0.16 to 0.58; external rotation: SMD 0.43, 95% CI 0.22 to 0.64; internal rotation: SMD 0.33, 95% CI 0.08 to 0.58), functional outcomes (Shoulder Pain and Disability Index: SMD -0.37, 95% CI -0.61 to -0.12; shortened Disabilities of the Arm, Shoulder and Hand questionnaire: mean difference [MD] -4.51, 95% CI -8.70 to -0.32), and quality of life (EuroQol Five Dimensions Questionnaire: MD 0.04, 95% CI 0.01 to 0.07). Telerehabilitation was not different from home-based exercise in terms of pain relief (SMD -0.19, 95% CI -0.60 to 0.23). Subgroup analysis demonstrated that telerehabilitation provided significant pain relief when sustained for over 12 weeks (SMD -0.46, 95% CI -0.81 to -0.11). Conclusions: Telerehabilitation is more effective than home-based exercise in improving range of motion, functional outcomes, and quality of life for patients with shoulder disorders. Telerehabilitation significantly outperforms home-based exercise in relieving pain when continued for over 12 weeks.
