Systemic gabapentin administration alleviated TRR-induced spontaneous pain. (A) preconditioning times spent in the saline- or gabapentin-paired chambers were equivalent across all groups and all data were pooled across groups for preconditioning graphical representation (mean ±SE, n=22). After conditioning, TRR rats spent more time in the gabapentin-paired chamber than in the saline-paired chamber. Naïve and sham rats showed no preference for the saline- or gabapentin-paired chamber. (B) TRR rats showed significantly increased of difference scores in the gabapentin-paired chamber. *P<0.05 compared with sham group (Kruskal-Wallis analysis with multiple comparisons with post hoc Dunn's test).
