		Number of perturbations per platform translation direction
		Forward	Backward	Left	Right
Day 1	*First perturbations	1		1
	Determination of step threshold	3	3	3	3
	‡Baseline lateral stepping			5	5
	‡Postural motor training	25	25
Day 2	*First perturbations	1		1
	Determination of step threshold	3	3	3	3
	‡Generalization lateral stepping			5	5
	‡Retention postural motor training	5	5

^*One toes up rotation was also included in the first perturbations, data not reported.

^‡Perturbation sequence was randomly ordered across directions.
