Figure 2

Crossed-withdrawal reflex measured by the response of the injured paw to stimulation of the uninjured paw on day 14 postoperatively. The frequency of the paw withdrawal was expressed as means ± S.E.M. and compared between actual applications (Stim) of von Frey filament and sham stimulation (Sham). (Control: control rats, Injured: neuropathic rats). An asterisk () indicates significant differences between actual applications of stimuli and sham stimulation, according to the paired t-test ().
