Mean (± SE) walking ability as measured by time (sec) to traverse an elevated wooden beam prior to, and after, TBI or SHAM injury. During the first phase of the experiment a single drug injection was provided 1 hr prior to testing on post-operative day 1 (arrow), which was followed by daily administrations on days 19–23 during the second phase, and no treatments during the third phase, which consisted of days 24–26. (A) No significant differences were revealed among TBI groups, albeit all were markedly impaired relative to SHAM controls. (B) ⁺*p < 0.05 vs. all other groups, but not each other, during daily administration. (C) Assessment at three days after the discontinuation of daily treatment revealed no statistically significant differences among groups (p > 0.05, Bonferroni post-hoc).
