Table 1

Gait parameter average for all valid steps.

Weeks	Foot	Parameter	Parameter description
T2_1: differences between T2 and T1	R: right	XCoP	Center of pressure (-coordinate)
		YCoP	Center of pressure (-coordinate)
		PFT	Peak pressure at the first toe sensor
		PHL	Peak pressure at the heel sensor
T3_2: differences between T3 and T2	L: Left	PM1	Peak pressure at the 1st metatarsal sensor
		PM5	Peak pressure at the 5th metatarsal sensor
		SPT	Stance phase time
