| Summary: | <p>Abstract</p> <p>Background</p> <p>The purpose of this study was to determine the test-retest reliability of temporal and spatial gait measurements over a one-week period as measured using an instrumented walkway system (GAITRite<sup>®</sup>).</p> <p>Methods</p> <p>Subjects were tested on two occasions one week apart. Measurements were made at preferred and fast walking speeds using the GAITRite<sup>® </sup>system. Measurements tested included walking speed, step length, stride length, base of support, step time, stride time, swing time, stance time, single and double support times, and toe in-toe out angle.</p> <p>Results</p> <p>Twenty-one healthy subjects participated in this study. The group consisted of 12 men and 9 women, with an average age of 34 years (range: 19 – 59 years). At preferred walking speed, all gait measurements had ICC's of 0.92 and higher, except <it>base of support </it>which had an ICC of 0.80. At fast walking speed all gait measurements had ICC's above 0.89 except <it>base of support </it>(ICC = 0.79),</p> <p>Conclusions</p> <p>Spatial-temporal gait measurements demonstrate good to excellent test-retest reliability over a one-week time span.</p>
