Comparison of “No Perceived Improvement” versus “Perceived Improvement” groups

	No Perceived Improvement Group	Perceived Improvement Group	P-value*
Ability to walk leisurely
n	11	11
Self-paced 5-m walk speed change, m/s	0.03 ± 0.13 (−0.22, 0.27)	0.1 ± 0.14 (−0.14, 0.32)	0.30
Ability to walk fast
n	13	9
Fast-paced 5-m walk speed change, m/s	0.05 ± 0.1 (−0.9, 0.2)	0.09 ± 0.18 (−0.18, 0.41)	0.60
Ability to walk long period of time
n	13	9
6MWT distance change, m	8.9 ± 40.7 (−53, 105)	43.3 ± 34.3 (−7, 82)	0.04**

No Perceived Improvement Group where Self-reported change +1 and below; Perceived Improvement Group where Self-reported change +2 and above. Values are n or mean ± SD (min, max). Abbreviation: 6MWT – 6-Minute Walk Test.

^*Mann-Whitney U tests were performed to compare measured change in each outcome between the Perceived versus No Perceived Improvement groups
