Abstract
Aim: This study aimed to compare the effectiveness of a hospital-based sports rehabilitation program (SRP) versus a home-based exercise program (HEP) on motor function, participation-related, and therapy engagement outcomes in children with developmental disabilities and to evaluate feasibility and safety.
Methods: This exploratory randomized pilot study allocated 16 children to SRP or HEP (1:1) using block randomization stratified by Gross Motor Function Classification System (GMFCS) level. Both interventions were delivered for 8 weeks. Outcomes included Gross Motor Function Measure (GMFM), Pediatric Balance Scale (PBS), Canadian Occupational Performance Measure (COPM-Performance/Satisfaction), Pediatric Volitional Questionnaire (PVQ), and Goal Attainment Scaling (GAS; T-score). A 2×2 mixed ANOVA (group × time) was used for most outcomes, and an independent t-test was used for GAS T-scores.
Results: Both groups showed significant improvements over time in GMFM and PBS (p < 0.001). Group-by-time interactions favored SRP for COPM–Performance (p = 0.038), COPM–Satisfaction (p = 0.025), and PVQ (p = 0.038). The GAS T-scores did not differ between the groups (p = 0.645). Feasibility criteria were met (≥75% adherence, fidelity, and exercise dose).
Conclusion: Both interventions were feasible and safe over 8 weeks. The SRP may confer greater benefits for participation-related outcomes. Future adequately powered trials with a longer follow-up period are warranted to confirm these findings.
