Figure 2.

Each graph shows single subject behavioral data describing the step length symmetry of sequential strides in each condition. (A) The rectangular dotted area demonstrates the step symmetry during the catch trial after 10 min of split adaptation; this reflects retention of the new locomotor pattern. (B) Note that during the tied random condition asymmetric steps were present. These occurred when there were transitions between speeds. (C) During the tied constant condition, there is little variability in step symmetry. (D) Group data showing the step symmetry variance during each condition. Please note that variance during split adaptation and tied random conditions were similar and higher than tied constant condition. *P < 0.05.
