Evaluation of cord central pain in patients with paraplegia before, 1 and 6 months after the surgery (visual analog scale, VAS). The VAS of one patient (SCF011) who had no spinal central pain before the surgery developed after the SNT. The VAS of seven patients (SCF001, SCF004, SCF005, SCF006, SCF008, SCF010, SCF012) after the surgery gradually decreased compared with that before the surgery. The remaining patients were unchanged (1–12 on the horizontal axis represents SCF001-SCF012, see in (A). The difference between VAS before and 6 months after the surgery was statistically significant by a paired sample t-test, p < 0.05 (B).
