Symmetry indices for mean (M) and peak (P) as well as the sum (S) of the braking (Fy-) and propulsive (Fy+) forces for the sound condition and when lameness was induced.

Prefect symmetry is represented by SI = 0. Negative values indicate the respective parameter was greater for the contra- than the ipsilateral limb; positive values indicate a greater value for the ipsi- than the contralateral side. Significant differences between sound and lame conditions at * p
