Time to peak force (TPF) and the duration of the braking force (TFy−) are given in percent of stance duration. Significant differences between sound and lame conditions at * p<0.05; n.s. = not significant. Fi = ipsilateral forelimb, Fc = contralateral forelimb, Hi = ipsilateral hindlimb, Hc = contralateral hindlimb.
