Reliability of gait performance tests in men and women with hemiparesis after stroke.
Author
Summary, in English
Objective: To assess the reliability of 6 gait performance tests
in individuals with chronic mild to moderate post-stroke
hemiparesis.
Design: An intra-rater (between occasions) test-retest
reliability study.
Subjects: Fifty men and women (mean age 586.4 years)
6–46 months post-stroke.
Methods: The Timed “Up & Go” test, the Comfortable and
the Fast Gait Speed tests, the Stair Climbing ascend and
descend tests and the 6-Minute Walk test were assessed 7
days apart. Reliability was evaluated with the intraclass
correlation coefficient (ICC2,1), the Bland & Altman
analysis, the standard error of measurement (SEM and
SEM%) and the smallest real difference (SRD and SRD%).
Results: Test-retest agreements were high (ICC2,1 0.94–0.99)
with no discernible systematic differences between the tests.
The standard error of measurement (SEM%), representing
the smallest change that indicates a real (clinical) improvement
for a group of individuals, was small (9%). The
smallest real difference (SRD%), representing the smallest
change that indicates a real (clinical) improvement for a
single individual, was also small (13–23%).
Conclusion: These commonly used gait performance tests
are highly reliable and can be recommended to evaluate
improvements in various aspects of gait performance in
individuals with chronic mild to moderate hemiparesis after
stroke.
