OBJECTIVES: To examine (1) the intra-rater, interrater, and test-retest
reliabilities of the timed Up and Go test with a motor task (TUGmotor) in terms
of the number of steps taken in the test and completion time in a population with
chronic stroke ; (2) the relation between stroke-specific impairments and the
number of steps taken in the test and the completion time ; (3) the minimum
detectable change in TUGmotor times ; and (4) the cutoff time that best
discriminates the performance of people with stroke from that of older adults
without stroke. DESIGN: Cross-sectional study. SETTING: University-based
rehabilitation center. PARTICIPANTS: A sample (N=65) of chronic stroke survivors
(n=33) and healthy older adults (n=32). INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: TUGmotor times and number of steps taken; Fugl-Meyer Assessment
for the Lower Extremities score; handheld dynamometer measurements of hip
abductor, knee flexor and extensor, and ankle dorsiflexor and plantar flexor
muscle strength; 5-times sit-to-stand test time, Berg Balance Scale score;
conventional timed Up and Go test time, and Activities-specific Balance
Confidence scale and Community Integration Measure questionnaire scores. RESULTS:
The TUGmotor completion times and number of steps demonstrated excellent
intra-rater, interrater, and test-retest reliabilities. The TUGmotor times
correlated significantly with the Fugl-Meyer Assessment for the Lower Extremities
and Berg Balance Scale scores, with hip abductor, knee flexor, ankle dorsiflexor
and plantar flexor strength on the paretic side, with 5-times sit-to-stand test
times, and with times on the conventional timed Up and Go test. The minimum
detectable change in TUGmotor time was 3.53 seconds in stroke survivors. A TUGmotor cutoff time of 13.49 seconds was found to best discriminate the
performance of stroke survivors from that of older adults without stroke.
CONCLUSIONS: The TUGmotor is a reliable, valid, and easy-to-administer clinical
tool for assessing advanced functional mobility after a stroke.
