Fig. 3.

A: comparison of a weight-supported step where the animal clears the surface of the treadmill and a nonweight-supported step. B: average time differences in sequential forepaw footfalls between spinalized and normal rats. During treadmill induced locomotion, the average time between forepaw footfalls was less than that for spinalized rats. C: average time differences in sequential forepaw placements of spinalized rats negatively correlated with percentage of weight-supported steps (%WSS) during treadmill-induced locomotion. R = -0.66; P < 0.05. For the spinalized rats with lower %WSS, more time elapsed between sequential right and left forepaw placements.
