Change in speed, percent weight support, and walking time over twelve weeks (𝑁=8).

	Week one	Six weeks	Twelve weeks	𝑃 value*
	Mean ± SD	Mean ± SD	Mean ± SD
Walking speed (m/s)	0.80±0.27	0.89±0.27	0.94±0.13	0.01
% of body weight supported	5.6±2.8	3.4±3.9	0	0.02
Walking time (min)	11.5±4.3	18.0±2.4	20.0±0	<0.001

SD: standard deviation; m/s: meters per second; min: minutes; *for change over twelve weeks, controlling for baseline value of outcome variable and count of baseline diseases/symptoms.
