Response characteristics of spinal dorsal horn neurons to plantarflexion (PF) of the foot in normal and ankle-sprained rats. PF was initiated from the tibiotarsal-tarsometatarsal (TT-TM) angle of 90° (baseline) and ended at 190°. The neurons responding exclusively to PF were recorded in normal (A) and sprained (B) rats. Insets show raw recordings of single spikes. C: mean evoked responses to PF. D: afterdischarges of the dorsal horn neurons recorded from normal rats (n = 16) and 1 day postankle-sprained rats (n = 21). Asterisks indicate values significantly different from the normal value (*P < 0.05; **P < 0.01).
