Clinical Interpretation of a Lower-Extremity Functional Scale–Derived Computerized Adaptive Test

BACKGROUND: The increasing use of computerized adaptive tests (CATs) to generate outcome measures during rehabilitation has prompted questions concerning score interpretation. OBJECTIVE: The purpose of this study was to describe meaningful interpretations of functional status (FS) outcome measures estimated with a body part-specific CAT developed from the Lower-Extremity Functional Scale (LEFS).
