A Split-belt paradigm. B Schematic of a typical response of a neurologically intact subject to the split-belt paradigm. Dashed lines represent the fast leg step length and solid lines represent the slow leg step length for both the Tied Belt and Split Belt conditions. With the tied belt condition both slow and fast leg step lengths are similar. Asymmetry between the fast and slow leg step length is noted in early adaptation, with reduction in step length asymmetry during late adaptation.
