|Abstract: ||Abstract: Background: Simple field tests such as the Timed Up and Go test (TUG) and 30 s Chair
Stand test are commonly used to evaluate physical function in the elderly, providing crude
outcome measures. Using an automatic chronometer, it is possible to obtain additional kinematic
parameters that may lead to obtaining extra information and drawing further conclusions.
However, there is a lack of studies that evaluate the test-retest reliability of these parameters, which
may help to judge and interpret changes caused by an intervention or differences between
populations. Thus, the aim of this study was to evaluate the test-retest reliability of the Timed Up
and Go test (TUG) and 30 s Chair Stand test in healthy older adults. Methods: A total of 99 healthy
older adults participated in this cross-sectional study. The TUG and the 30 s Chair Stand test were
performed five times and twice, respectively, using an automatic chronometer. The
sit-to-stand-to-sit cycle from the 30 s Chair Stand test was divided into two phases. Results: Overall,
reliability for the 30 s Chair Stand test was good for almost each variable (intraclass correlation
coefficient (ICC) >0.70). Furthermore, the use of an automatic chronometer improved the reliability
for the TUG (ICC >0.86 for a manual chronometer and ICC >0.88 for an automatic chronometer).
Conclusions: The TUG and the 30 s Chair Stand test are reliable in older adults. The use of an
automatic chronometer in the TUG is strongly recommended as it increased the reliability of the
test. This device enables researchers to obtain relevant and reliable data from the 30 s Chair Stand
test, such as the duration of the sit-to-stand-to-sit cycles and phases.|
