Effect of CIMT on body weight and plasma corticosterone levels. (A and B) A CIMT-treated rat, with restraint to the unaffected forelimb by wearing a pouch, forcing the use of the affected limb on a motorized treadmill. (C) Timeline of the experimental design. (D) Body weight was monitored from 3 weeks after HI injury, and measured up to 6 weeks after HI injury. Groups were as follows: HI, HI injury and non-treated group (HI/vehicle: n=12); 10, HI injury and CIMT for 10 min (n=12); 20, HI injury and CIMT for 20 min (n=12); 30, HI injury CIMT for 30 min (n=12). (E) Corticosterone concentration in plasma was determined by ELISA assay at 7 weeks after HI. *P<0.05 vs. sham group (unpaired t-test). HI, hypoxic-ischemic; CIMT, constraint-induced movement therapy.
