Abbreviations: min, minimum; max, maximum; AD, assistive device; RW, rolling walker; SSWS, self-selected walking speed; MWS, maximal walking speed; WSRdiff, walking speed reserve calculated as a difference (MWS – SSWS); WSRratio, walking speed reserve calculated as a ratio (MWS/SSWS)

Units of measure: age, years; SSWS, MWS, WSRdiff, m/s
