This randomized controlled trial will compare the effectiveness of static progressive splinting versus dynamic splinting for treating persistent wrist stiffness in adults ≥18 years old at least 8 weeks post distal radius fracture (DRF) injury. Both splinting modalities are provided as an adjunct to one weekly supervised therapy session over a 6-week period. The primary outcomes are wrist active and passive range of motion (AROM/PROM) measured using goniometry, with secondary outcomes including patient-reported wrist function (PRWE), overall satisfaction, and adverse events.
