Catwalk automated gait analysis of rats with a photothrombotic stroke compared to sham operated animals. Experimental groups were prepared and submitted to catwalk gait analysis as described in Materials and Methods. Depicted are mean ratios (± s.e.m.) of pawprint intensity (A), print area (B), print width (C) and max area (D) parameters of stroke animals vs. sham operated animals for each limb. All parameters showed lower values for the contralateral hindlimbs in comparison to the ipsilateral hindlimbs. * p < 0.05.
