Mobility assessment: sensitivity and specificity of measurement sets in older adults.

ABSTRACT:

Objective

To identify quantitative measurement variables that characterize mobility in older adults, meet reliability and validity criteria, distinguish fall risk, and predict future falls.

Design

Observational study with 1-year weekly falls follow-up.

Setting

Mobility laboratory.

Participants

Community-dwelling volunteers (N=74; age, 65-94y) categorized at entry as 27 nonfallers or 47 fallers by using Medicare criteria (1 injury fall or >1 noninjury fall in the previous year).

Interventions

None.

Main outcome measures

Test-retest and within-subject reliability, criterion and concurrent validity; predictive ability indicated by observed sensitivity and specificity to entry fall-risk group (falls status), Tinetti Performance Oriented Mobility Asses
