Abstract — This study assessed inter- and intrarater reliability and sensitivity to change of the 2-, 6-, and 12-minute walk tests following stroke. A convenience sample of patients enrolled in an inpatient stroke rehabilitation program participated in the standardization protocol. The 2-, 6-, and 12-minute walk tests were performed and inter- and intrarater reliability and responsiveness to change assessed. The interrater intraclass correlation coefficients (ICCs) for the 2-, 6-, and 12-minute walk tests were, respectively, 0.85, 0.78, and 0.68 (p < 0.0007 for each). The intrarater ICCs were 0.85, 0.74, and 0.71 (p < 0.0003 for each). Responsiveness to change as measured by standardized response mean (SRM) scores was, respectively, 1.34, 1.52, and 1.90 (F = 24.24, p < 0.001). Pearson correlations for the 2-, 6-, and 12-minute walk tests by the same rater on the same day were 2 versus 6 minutes, r = 0.997; 2 versus 12 minutes, r = 0.993; and 6 versus 12 minutes, r = 0.994 (p < 0.0001 for each). The 2-, 6-, and 12-minute walk tests show acceptable inter- and intrarater reliability and high intertest correlations when they are used for the assessment of walking following stroke. The SRM statistic indicates that the 12-minute walk test is the most responsive to change.
Key words: cerebrovascular disorders, exercise, gait, outcomes assessment, rehabilitation, stroke, walking endurance, walking speed.
