OBJECTIVES: To investigate the intra- and interrater reliabilities of the
Expanded Timed Up and Go (ETUG) test with subjects with stroke and to compare the
ETUG scores between subjects with stroke and healthy control subjects.
DESIGN : Cross-sectional.
SETTING : Research laboratory. PARTICIPANTS:
Stroke participants
(n=48; mean age +/- SD, 59.29+/-15.84y) and healthy controls (n=48), matched by
age, sex, and levels of physical activity. INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: The time spent to complete the ETUG in absolute (s) and ratio
values regarding the percentages of the total time. Intraclass correlation
coefficients (ICCs), Student t tests, and 95% confidence intervals were employed
to investigate the reliability and differences between the groups (alpha<.05).
RESULTS: Both intra- and interrater reliabilities showed significant and
excellent results for both groups for the absolute values (0.86</=ICC</=1.00;
P<.001) and ratio values (0.55</=ICC</=0.99; P<.001). The mean time, in seconds,
for all of the ETUG activities was higher for the subjects with stroke than for
the control subjects (3.15</=t</=5.78; P<.001). However, when the comparisons
considered the ratio values, no significant differences between the groups were
found (0.45</=t</=1.15; 0.25</=P</=0.65). These results were confirmed by the 95%
confidence interval. CONCLUSIONS: Subjects with stroke spent more time in all of
the ETUG activities when compared with control subjects. All of the activities
appeared to contribute similarly to the poorer performances observed in subjects
with stroke, because the ratio values were similar between the groups.
Considering the positive intra- and interrater reliability results, the ETUG
could be applied to assess the functional mobility of both groups.
