		Normal Walk
		Total		FU		FTU		Significance

Spatio-temporal gait parameters		Mean	± SD	Mean	± SD	Mean	± SD	p
Velocity	(cm/s)	73.1	±21.3	65.8	±20.5	83.4	±18.0	<0.001

Stride time variability	(%CV)	4.2	±2.5	4.7	±2.8	3.4	±1.7	0.005
Double support time variability	(%CV)	7.6	±4.0	8.0	±4.6	7.0	±3.0	0.234
sagittal plane gait parameters		n = 96		n = 58		n = 38
Toe off angle	(°)	42.1	±8.1	40.6	±8.8	44.8	±6.2	0.005
Heel strike angle	(°)	11.8	±4.9	10.7	±4.9	13.5	±4.5	0.009
Max. toe clearance	(cm)	6.1	±2.0	5.6	±1.9	6.9	±2.1	0.003

FTU = first time WW user, FU = frequent WW user, (°) = degree, (cm) = centimeter, (% CV) = coefficient of variation, calculated by the formula: [CV (%) = SD/Mx100]; Significance was calculated for the difference in gait parameters between FU and FTUs (unpaired t-test, 2-sided)
