Identifying a cut-off point for Timed Up and Go Test and 30-second Chair Stand Test in dual-task condition: Effects of cognitive status

Abstract

A decline in mental function is a common problem associated with aging. The most commonly used tests for evaluating functional mobility, fall risk, and lower limb strength of older adults in the clinic are ‘Timed Up and Go Test’ and ‘30-second Chair Stand Test’. This study was planned to determine the cut-off point of these tests in cognitive declines. A total of 204 older adults aged 65 years and over participated in this study. To examine the cut-off points of tests for single and dual-tasks, count off by twos was added as a cognitive task. The cut-off points of tests without and with an additional task were determined as 10.54, 12.21 second, 10.5, and 8.5 stands respectively. These results are important to reveal the effects of mental declines should be taken into account when interpreting the results of clinical functional mobility assessments in older adults.
