OBJECTIVES: To compare the ability of Timed Up and Go (TUG) and usual gait speed
(UGS) to predict incident disability completing basic activities of daily living
(ADL) and instrumental ADL (IADL) in older adults free of disability at baseline,
and to provide estimates for the probability of incident disability at different
levels of baseline mobility performance. DESIGN: Data from the first 2 waves of
The Irish Longitudinal Study on Ageing, a study assessing health, economic, and
social aspects of ageing in adults aged >/=50 years. SETTING: A nationally
representative, population-based sample of community-dwelling adults.
PARTICIPANTS: Participants aged >/=65 years who completed mobility tests during a
health assessment, had no reported difficulty in ADL/IADL, and had a Mini-Mental
State Examination score >/=24 were re-interviewed after 2 years (n=1664).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants completed the
TUG and UGS at baseline and indicated difficulty in a number of basic ADL and
IADL at follow-up. RESULTS: Receiver operating characteristic analysis indicated
that TUG and UGS are acceptable tools to predict disability in ADL and IADL (area
under the curve [AUC]=.65-.75) with no significant difference between them
(P>.05). Both were excellent predictors of difficulty in higher-level functioning
tasks such as preparing hot meals, taking medications, and managing money
(AUC>.80). Predictive probabilities were obtained across a range of performance
levels. CONCLUSIONS: TUG and UGS have similar predictive ability in relation to
incident disability in basic ADL and IADL. Predictive probabilities can be used
to identify those most at risk and in need of particular services. Since
improving physical function can prevent or delay dependence in ADL/IADL, TUG and
UGS can also provide performance goals and feedback during exercise
interventions.
