mobility in people with stroke.

AB - BACKGROUND: The Timed Stair Test (TST) was originally designed to measure
advanced functional mobility in patients who have undergone a total hip
replacement. Its psychometric properties have not been examined systematically in
people with stroke. AIM: The aims of this study were to: 1) determine the
intra-rater reliability of TST under loaded and unloaded condition; 2) identify
the minimal detectable changes (MDCs) in TST completion times; 3) investigate the
concurrent validity between TST completion times and stroke-specific outcome
measures; and 4) determine the cut-off TST completion time to differentiate the
performance between people with stroke and healthy older adults. DESIGN:
Cross-sectional study. SETTING: A university-based rehabilitation center.
POPULATION: Ninety-four people with stroke and 34 healthy older adults. METHODS:
TSTs were conducted under loaded and unloaded conditions. Two trials of the TST
for each of the two conditions were performed on the same day. The Fugl-Meyer
Assessment of Lower Extremity (FMA-LE), lower-limb muscle strength test assessed
by a hand held dynamometer, Berg Balance Scale (BBS), Limit of Stability (LOS)
Test, Timed Up and Go (TUG) Test, and the Cantonese version of the Community
Integration Measure (CIM) were also used to assess the subjects. RESULTS:
Excellent intra-rater reliability was demonstrated for TST completion times under
loaded (intraclass correlation coefficient [ICC2,1]=0.991) and
unloaded (ICC2,1=0.985) conditions. The MDCs in TST completion times
were 6.55 seconds and 7.25 seconds under loaded and unloaded conditions,
respectively. FMA-LE scores, mean strength of the affected-side dorsiflexors and
plantar flexors, BBS scores, and LOS movement velocity and maximum excursion
scores demonstrated fair to excellent negative correlations with TST completion
times under both loaded (r=-0.314 to -0.786) and unloaded (r=-0.296 to -0.794)
conditions. TUG results demonstrated good to excellent positive correlations with
TST completion times under both loaded (r=0.875, P<0.001) and unloaded (r=0.872,
P<0.001) conditions. The TST completion times of 26.3 seconds and 23.4 seconds
under loaded and unloaded conditions, respectively, differentiated between people
with stroke and healthy older adults. CONCLUSIONS: The TST is a reliable clinical
tool for evaluating advanced functional mobility in people with stroke. CLINICAL
REHABILITATION IMPACT: TST is a fast and simple test that does not require
sophisticated equipment, making it suitable for busy hospital and rehabilitation
settings.
