Footprint characteristics of the forepaw.

<p>Mean values±SD of the gait parameters print area (A), lengths of the print (C), stride-lengths (B) and track-widths (D) for young (black) and aged rats (red), * p<0.01. (A+C): The limb-specific parameter print area was reduced and print lengths remained unchanged in aged rats, which was not the case for the hindpaw (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003399#pone-0003399-g005" target="_blank">Fig. 5</a>). (B+D): The global walking parameters stride-lengths decreased and track-widths increased in aged rats. This was also observed for the hindpaw (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003399#pone-0003399-g005" target="_blank">Fig. 5</a>).
