The purpose of this study was to determine the test-retest reliability and concurrent and construct validity of the 6MWT in patients who were actively undergoing inpatient rehabilitation poststroke. 37 patients underwent two 6MWT trials with 1-3 days between trials. The 6MWT exhibited high test-retest reliability and was strongly to moderately correlated with gait speed and Functional Independence Measure.
The 6MWT is a clinically useful measure of walking ability poststroke. It is reliable and is related to other measures of walking ability and function that are commonly used during rehabilitation after stroke.
