The aim of this study was to investigate the reliability of temporal and spatial
gait parameters in patients dependent on walking assistance after severe stroke,
and to examine agreement between simple and advanced methods. Twenty-one
patients, admitted for in-patient multidisciplinary rehabilitation, were assessed
repeatedly for walking function, both in a test corridor and a gait laboratory
(3D camera system) before and after 11 weeks of rehabilitation. The test-retest
reliability was examined using intraclass correlation (ICC1.1), and measurement
error was reported by within-subject standard deviation (Sw). The agreement
between different methods for assessing walking speed, cadence and step length
was explored by Bland-Altman plots. High to excellent test-retest reliability was
found between trials, both when assessed in the corridor (ICC: 0.93-0.99) and in
the laboratory (ICC: 0.88-0.99). Agreement between methods was satisfactory at
baseline and was higher after the rehabilitation period. Agreement was found to
be slightly better at lower walking speeds and for shorter step lengths. The results implicate that temporal-spatial gait parameters may be measured reliably
by both simple and advanced methods in dependent walkers after stroke. A high
level of agreement was found between the two methods for walking speed, cadence
and average step length at both test points.
