OBJECTIVE: To evaluate the classic psychometric and clinical profile of the Unified Balance Scale, a novel Rasch-based measure of balance. METHODS: The Unified Balance Scale was administered to 219 neurological patients (providing 302 observations) admitted to rehabilitation, together with: Timed Up & Go, 10-meters walking test, Functional Ambulation Classification (FAC), Walking Handicap Scale, FIM™, Trunk Control Test, Motricity Index, and posturographic indexes. Analyses included: concurrent validity, external construct validity (convergent, divergent and discriminant validity), responsiveness, interpretability, predictive validity and usability. RESULTS: External construct validity (e.g. correlation with FAC: rho=0.80Downloads
