ObjectivesTo examine: (1) the intra-rater, inter-rater and test-retest reliabilities of the timed up and go (motor) test (TUGmotor) in terms of the number of steps taken and completion time with a chronic stroke population; (2) the relationship between stroke-specific impairments and the number of steps taken in the test and the completion time; (3) the minimal detectable change in TUGmotor times; and (4) the cut-off time which best discriminates the performance of people with stroke from that of healthy older adults.DesignA cross-sectional studySettingA university-based rehabilitation centreParticipantsThirty-three chronic stroke survivors and 32 healthy older adultsMain Outcome MeasuresThe TUGmotor times and the number of steps taken; the Fugl-Meyer Assessment for the Lower Extremities (FMA-LE); hand-held dynamometer measurements of hip abductor, knee flexor and extensor, and ankle dorsiflexor and plantarflexor muscle strength; the 5-times-sit-to-stand test (FTSTS), the Berg Balance Scale (BBS); the conventional Timed Up and Go Test (TUG), and assessment using the Activities-specific Balance Confidence Scale (ABC) and the Community Integration Measures (CIM) questionnaire.ResultsTUGmotor completion times and number of steps demonstrated excellent intra-rater, inter-rater and test-retest reliabilities. The TUGmotor times correlated significantly with the FMA-LE and BBS scores, with hip abductor, knee flexor, ankle dorsiflexor and plantarflexor strength on the paretic side, with FTSTS times and with times on the conventional TUG test. The minimal detectable change in TUGmotor time was 3.53 seconds with the stroke survivors. A TUGmotor cut-off time of 13.49 seconds was found to best discriminate the performance of stroke survivors from that of healthy older adults.ConclusionsThe TUGmotor is a reliable, valid and easy-to-administer clinical tool for assessing advanced functional mobility after a stroke.
