The objective of this study is to establish test−retest reliability and minimal detectable change (MDC) of the timed up and go (TUG) test in older adults with peripheral vestibular hypofunction. A pragmatic descriptive design was used on the data collected on 16 patients. Inclusion criteria were age 65 years or older evaluated in physical therapy for symptoms of dizziness and/or postural instability, able to walk without the physical help of another person, and able to follow commands and perform the examination instructions in English. Exclusion criteria were unstable medical issues, orthostatic hypotension, uncontrolled metabolic disease; history of falls from syncopal origin; dizziness of central origin, active benign paroxysmal positional vertigo, and inability to walk without physical assistance. After the patients gave informed consent and met the inclusion criteria, the patients performed one practice trial followed by two final performances of the TUG that were included in the data analysis. The TUG test measures the time it takes to stand up from a chair, walk three meters, turn around, get back to the chair, and sit down. The TUG showed excellent reliability. TUG has small values for both standard error of measurement (0.46 seconds) and MDC90 (1.07 seconds). The generalization of results of TUG test−retest is limited among the older adults with subacute and chronic peripheral vestibular hypofunction. The test−retest reliability of the TUG for older adults with peripheral vestibular hypofunction is equivalent to that of older adults with other conditions.
