Table 3. The symmetry ratio of foot clearance for both groups while crossing an obstacle height corresponding to 10% of subjects’ leg length.

Group	High risk	Low risk
Heel clearance *	−1.1 ± 0.2	−0.9 ± 0.2
Peak heel clearance*	−0.2 ± 0.1	−0.2 ± 0.1
Toe clearance *	−0.2 ± 0.2	0.0 ± 0.2
Peak toe clearance *	−0.1 ± 0.1	0.0 ± 0.1

*p-values (<0.05) for the between-group variables; student t-test.
