Validity data of postural stability variables for slip–trip perturbation tests.

Variable	R Value	ICC	RMSE	Limits of Agreement
SLIP
Stability at TD of the recovery foot	0.59	0.56 *	0.20	−0.48–0.56
Stability at TD of the slipping foot	0.81	0.72 *	0.17	−0.23–0.45
Step length at TD	0.68	0.64 *	0.11	−0.24–0.39
TRIP
Stability at TD of the recovery foot	0.61	0.50 *	0.16	−0.21–0.43
Stability at TD of the slipping foot	0.77	0.71 *	0.15	−035–0.42
Step length at TD	0.68	0.64 *	0.11	−0.29–0.22

Abbreviations: TD = Touchdown, R = correlation coefficient, ICC = intraclass correlation coefficient, RMSE = root mean square error, significant level of validity was shown by * denoting p < 0.05.
