Scores from measures of walking ability

Variable	Baseline	3 Months	Measured Change scores	P-value for measured change over time*	Perceived change
Ability to walk leisurely
Self-paced 5-m gait speed, m/s	0.83 ± 0.42 (0.12, 1.52)	0.89 ± 0.46 (0.14, 1.7)	0.06 ± 0.13 (−0.22, 0.32)	0.03**	1.9 ± 2.2 (−2, +6)
Ability to walk fast
Fast-paced 5-m gait speed, m/s	1.16 ± 0.64 (0.16, 2.4)	1.22 ± 0.71 (0.16, 2.54)	0.06 ± 0.14 (−0.18, 0.41)	0.04**	1.5 ± 2.2 (−2, +7)
Ability to walk for long period of time
6MWT distance, m	297.9 ± 175.3 (39, 593)	320.9 ± 179.8 (44, 628)	23.0 ± 41.1 (−53, 105)	0.02**	1.4 ± 2 (−2, 5)

Values are mean ± SD (min, max). Abbreviation: 6MWT – 6-Minute Walk Test

^*Paired t-tests were used to compare the mean baseline scores to mean scores at 3 months
