Correlation between outcomes of timed up and go (TUG) and five times sit to stand (FTSS) tests with trunk stability

Raw data of completion time and trunk accelerometry for three versions of the TUG (conventional [TUG-C], dual-task [TUG-DT], and overline [TUG-OL] and the five times sit to stand (FTSS) tests. The first three columns (t1-t3) correspond to data of individual trials and the fourth column corresponds to means (M) for each participant (lines). In the current investigation, we assessed older individuals, with the following primary aims: (1) to evaluate the correlation of completion times observed in the FTSS and in different versions of the TUG test with a direct measurement of trunk stability given by accelerometry while performing these tests; (2) to compare completion time and trunk stability of a new version of the TUG test requiring increased dynamic balance with the versions being currently used of this test. As a secondary aim, we evaluated the correlation between tests for both completion time and trunk acceleration to estimate the extent to which performance in one test can predict performance in the others. The results indicated negative time-acceleration correlations for TUGC (rp = -.71, rp2 =.50, p
