Comparison of the limb symmetry index for different directions and different velocities. The LSI at 60°/s in plantar flexion was significantly lower than that in dorsiflexion. LSI, limb symmetry index; DF, dorsiflexion; PF, plantar flexion; IV, inversion; and EV, eversion. *** Significant difference with p < .001
