The instrumented Timed "Up and Go" Test (iTUG) has the potential for playing an
important role in providing clinically useful information regarding an
individual's balance and mobility that cannot be derived from the original
single-outcome Timed "Up and Go" Test protocol.
The purpose of this study was to
determine the reliability and validity of the iTUG using body-fixed inertial
sensors in people affected by stroke. For test-retest reliability analysis, 14
individuals with stroke and 25 nondisabled elderly patients were assessed. For
validity analysis, an age-matched comparison of 12 patients with stroke and 12
nondisabled controls was performed. Out of the 14 computed iTUG metrics, the
majority showed excellent test-retest reliability expressed by high intraclass
correlation coefficients (range 0.431-0.994) together with low standard error of
measurement and smallest detectable difference values. Bland-Altman plots
demonstrated good agreement between two repeated measurements. Significant
differences between patients with stroke and nondisabled controls were found in 9
of 14 iTUG parameters analyzed. Consequently, these results warrant the future
application of the inertial sensor-based iTUG test for the assessment of physical
deficits poststroke in longitudinal study designs.
