Influence of Procedural Factors on the Reliability and Performance of the Timed Up and Go Test in Older Adults

Document Type



“Timed up-and-go” (TUG) test is a clinical assessment commonly used to quantify functional mobility and fall risk in older adults. While the concept of the test is simple, procedural variations can significantly impact the reliability and the performance. The purpose of the study was to determine the influence of specific procedural factors on the test–retest reliability and TUG test performance in older adults.
