The effects of electroacupuncture (EA) on mechanical allodynia induced by chronic constrictive injury (CCI) in Sprague-Dawley (SD) rats. EA treatment was applied at day 8 after CCI. The rats received EA stimulation once every other day for 8–28 days (total of 11 times). Evaluations of mechanical withdrawal thresholds in the sham group, CCI-induced neuropathic pain (NeuP) model group (CCI group), and CCI-induced NeuP model with EA treatment group (EA group). All data are expressed as the mean ± SEM (n = 13 per group). **p < 0.01, ***p < 0.001 vs. the sham group; #p < 0.05, ##p < 0.01, ###p < 0.001 vs. the CCI group.
