IGF1 and stroke disorder: Treatment with 1 mg/kg of PEG-IGF-I, 3 hrs post-stroke was found to decrease the number of foot-faults from 2-weeks post-stroke (F(3,180) = 21.65; P < 0.0001: Fig. 3C), and a small improvement in the use of the impaired limb in the cylinder task was observed by week 6 post-stroke (F(3,180) = 4.098; P = 0.0076: Fig. 3F).
