Figure 1: Diagram of establishment of rat models and treatments for each group. (A) The coordinates were determined according to an illustration by Paxinos and Watson (Paxinos et al., 1980). (B) A hole 0.8 mm in diameter was created in the rat cranium, 3.1 mm posterior to the bregma and 3.3 mm lateral to the midline. (C) A coronal T2-weighted magnetic resonance imaging (MRI) image indicates the hematoma in the posterior limb of the left internal capsule (pink arrow). (D) The experimental outline. (E) Sham-operation was conducted in the sham-operation group (bilateral L4 nerve roots were not severed intraoperatively, n = 10). (F) Bilateral L4 nerve roots were sharply transected in the Bi-L4 transection group (n = 10), and the stumps were secured to the psoas major muscles or capped with soft tissues. (G) The L4-to-L4 transfer was performed in the L4-to-L4 root transfer group (n = 10). Contralesional L4 was resected as distally as possible, and the ipsilesional L4 was severed proximally. Interrupted suture was applied to anastomosis of stumps. L: Left; R: right.
