Abstract
Fifty older and 50 young adults executed three trials of each test on day 1 test and day 2 retest Lateral and longitudinal displacements and body rotation relative to the starting position were measured Means and standard deviations SD were compared between the two groups with Mann–Whitney tests Test–retest reliability was assessed with intraclass correlation coefficients ICC Foot preference was determined from the score on the Waterloo Footedness Questionnaire and correlated with test scoresLateral and longitudinal displacements were significantly larger in older than young participants on the Fukuda stepping test p 01 and significantly smaller on the BabinskiWeil test p 001 Older participants displayed a significantly smaller SD on the three BabinskiWeil test trials p 001 Displacement and rotation measures ICC ranged between 025 and 077 in older and between 058 and 080 in young participants Foot preference correlated with rotation on the Fukuda stepping test in young p 05 but not in older participants p 05Linear displacements but not body rotation were different between older and young adults There was no clear agerelated differences in test–retest reliability but the moderate reliability indicates that performance can vary from day to day in both age groups
