Abstract

Franchignoni F, Orlandini D, Ferriero G, Moscato TA. Reliability, validity, and responsiveness of the Locomotor Capabilities Index in adults with lower-limb amputation undergoing prosthetic training. Arch Phys Med Rehabil 2004;85:743-8. Objective To assess the reliability, validity, and responsiveness of both the standard and revised Locomotor Capabilities Index (LCI) in people with lower-limb amputation who undergo prosthetic training. Design Reliability and validity study. Setting Two freestanding rehabilitation centers. Participants Fifty inpatients with a recent unilateral lower-limb amputation. Interventions Not applicable. Main outcome measures The standard LCI and a new version with a 5-level ordinal scale (LCI-5) were tested for internal consistency, test-retest reliability, ceiling effect, and effect size. The construct validity of both versions was analyzed by correlation with the Rivermead Mobility Index, a timed walking test, and the FIM instrument. Results The Cronbach α of both LCI versions was .95. The item-to-total correlations (Spearman ρ) ranged from .50 to .87 (P
