TABLE 2.

Absolute mean values of the spatiotemporal gait parameters and stride duration variability assessed during Overground Walking (OW), Treadmill Walking (TW), and immersive Virtual Reality on Treadmill Walking (iVRTW) conditions and comparison between TW and iVRTW conditions.

	OW	TW	iVRTW	p-Value
Speed (m.s–1)	1.31(0.10)	1.14(0.13)	1.14(0.13)	1.000
Cadence (#steps.min–1)	110.3(6.4)	109.9(7.5)	105.2(5.6)	0.009
Step length (m)	0.71(0.05)	0.62(0.07)	0.65(0.06)	0.008
Mean stride duration (s)	1.09(0.06)	1.08(0.08)	1.14(0.06)	0.020
Coefficient of variation (%)	1.95(0.53)	2.98(1.34)	2.46(0.72)	0.177
α exponent	0.77(0.07)	0.85(0.07)	0.76(0.09)	0.016

Absolute value is expressed as mean (± SD). Bold data indicates if the comparison between TW and iVRTW (paired t-test) was significant (p < 0.05).
