Fig. 3. Post-injury administration of PFT-α or PFT-α (O) given at 5h but not 7 h improved functional outcomes as revealed by behavioral evaluation.

(A) Motor coordination measured by beam walking test. (B) Neurological function measured by mNSS. (C) Motor asymmetry measured by elevated body swing test (EBST) (D) Sensory-motor function measured by tactile adhesive removal test. Data represent the mean ±SEM. *P <0.05, ***P <0.001 versus sham group; ^#P<0.05, ^###P<0.001 versus TBI +veh group. (n=5 in each group). Note that when PFT was given at 7h post injury, it was much less effective.
