PURPOSE: To test the reliability of Timed Up and Go Tests (TUGTs) in cardiac
rehabilitation (CR) and compare TUGTs to the 6-Minute Walk Test (6MWT) for
outcome measurement. METHODS: Sixty-one of 154 consecutive community-based CR
patients were prospectively recruited. Subjects undertook repeated TUGTs and
6MWTs at the start of CR (start-CR), postdischarge from CR (post-CR), and 6
months postdischarge from CR (6 months post-CR). The main outcome measurements
were TUGT time (TUGTT) and 6MWT distance (6MWD). RESULTS: Mean (SD) TUGTT1 and
TUGTT2 at the 3 assessments were 6.29 (1.30) and 5.94 (1.20); 5.81 (1.22) and
5.53 (1.09); and 5.39 (1.60) and 5.01 (1.28) seconds, respectively. A reduction
in TUGTT occurred between each outcome point (P </= .002). Repeated TUGTTs were
strongly correlated at each assessment, intraclass correlation (95% CI) = 0.85
(0.76-0.91), 0.84 (0.73-0.91), and 0.90 (0.83-0.94), despite a reduction between
TUGTT1 and TUGTT2 of 5%, 5%, and 7%, respectively (P </= .006). Relative
decreases in TUGTT1 (TUGTT2) occurred from start-CR to post-CR and from start-CR
to 6 months post-CR of -7.5% (-6.9%) and -14.2% (-15.5%), respectively, while
relative increases in 6MWD1 (6MWD2) occurred, 5.1% (7.2%) and 8.4% (10.2%),
respectively (P < .001 in all cases). Pearson correlation coefficients for 6MWD1
to TUGTT1 and TUGTT2 across all times were -0.60 and -0.68 (P < .001) and the
intraclass correlations (95% CI) for the speeds derived from averaged 6MWDs and
TUGTTs were 0.65 (0.54, 0.73) (P < .001). CONCLUSIONS: Similar relative changes
occurred for the TUGT and the 6MWT in CR. A significant correlation between the
TUGTT and 6MWD was demonstrated, and we suggest that the TUGT may provide a related or a supplementary measurement of functional capacity in CR.
