COP characteristics

	Forward	Backward
COP amplitude (cm)
Initial, away from the target	3.1 ±0.2	3.3 ± 0.2
Toward the target	9.5 ±0.6	11.1 ±0.8
Median (IQR)
Initial, away from the target	3.3 (1.25)	3.4 (1.0)
Toward the target	8.6 (3.11)	10.4 (3.6)
[dCOP/dt]MAX (cm/s)
Initial, away from the target	19.01 ±2.6	15.2 ±1.5
Toward the target	51.5 ±4.3	69.8 ±7.4
Median (IQR)
Initial, away from the target	20.7 (13.8)	16.7 (6.8)
Toward the target	49.8 (20.6)	61.4 (44.9)

[dCOP/dt]_MAX represents the absolute value of the peak rate of COP shift.
