The Reliability of the Timed Up and Go Test among Portuguese Elderly

Assessment of dynamic balance is typically completed through functional tests, such as the Timed Up and Go (TUG) test, which measures the time it takes for an individual to stand up from a chair, walk a set distance, turn around, and sit back down. This test has been validated in several countries. However, in the Portuguese population there is a gap on testing the reliability of this functional test in a sample of the elderly both living in the community or in nursing homes. Thus, this study aimed at examining the reliability of the TUG in a sample of Portuguese elderly. An Intraclass Correlation Coefficient (ICC) analysis was performed between the first time (T1) and the time score after 16 weeks (T2) in TUG test by 38 males and 79 females aged between 60 and 92 years. The results showed acceptable scores of ICC in community-dwelling and nursing home resident elderly in both moments. In addition, significant differences were found between these groups of older adults, showing that community-dwelling elderly show greater agility and balance capacity compared to those living in nursing homes. Thus, the TUG test can be applied in the Portuguese elderly in both community-dwelling and nursing home resident elderly.
