Background. With the increasing incidence of Alzheimer disease (AD), determining the validity and reliability Of Outcome measures for people with this disease is necessary.
Objective. The goals of this study were to assess test-retest reliability of data for the Timed "Up & Go" Test (TUG), the Six-Minute Walk Test (6MWT), and gait speed and to calculate minimal detectable change (MDC) scores for each outcome measure. Performance differences between groups With mild to moderate AD and moderately severe to severe AD (as determined by the Functional Assessment Staging [FAST] scale) were Studied.
Design. This was a prospective, nonexperimental, descriptive methodological study. …
