Consistency and test–retest reliability of stepping tests designed to measure self-perceived and actual physical stepping ability in older adults

Background Older adults with an incorrect perception of their physical abilities may fall more often, suggesting a need for tests to quantify self-perceived and actual abilities. Aims To determine between-test consistency and test–retest reliability of three tests that measure self-perceived and actual stepping ability in older adults. Methods Older adults performed three stepping tests, covering high (bar test) and far steps (river and step tests). We studied between-test consistency in the perceived ability and actual ability of 269 participants at each task and in the difference between these two (degree of misjudgment). We also studied test–retest reliability in 21 participants. Results Perceived ability showed moderate consistency ( r = 0.46–0.55, p
