Table 1.

Margin of stability (MOS) values during the first half of the swing phase (minimum value) and at heel strike for ‘normal’ and extreme steps (both length and width). Values presented are least square means (adjusted for walking speed) with 95% confidence intervals in brackets.

	Normal steps	Long steps	Short steps	p-value
Min. MOSA in swing (cm)	−21.4 [−21.7, −21.1]	−22.2 [−22.5, −21.9]		0.0003*
MOSA at heel strike (cm)	10.3 [10.0, 10.6]	10.8 [10.5, 11.1]		0.0018*
Min. MOSP in swing (cm)	32.3 [31.8, 32.8]		32.4 [31.9, 32.9]	0.82
MOSP at heel strike (cm)	71.0 [70.6, 71.3]		69.3 [69.0, 69.7]	<0.0001*
	Normal steps	Wide steps	Narrow steps	p-value
Min. MOSM in swing (cm)	−4.3 [−4.6, −4.0]	−5.1 [−5.4, −4.8]		<0.0001*
MOSM at heel strike (cm)	17.1 [16.9, 17.2]	17.3 [17.2, 17.5]		0.019
Min. MOSL in swing (cm)	11.1 [10.8, 11.4]		11.1 [10.8, 11.3]	0.77
MOSL at heel strike (cm)	19.0 [18.7, 19.4]		18.4 [18.1, 18.8]	0.0008*
