Effect of Repeated Electroacupuncture Intervention on Hippocampal ERK and p38MAPK Signaling in Neuropathic Pain Rats

Figure 1

Effect of EA of ST36-GB34 on pain scores in CCI rats of different groups. Thermal pain thresholds after injury and EA are presented as mean ± SD ( in each group; compared with the sham control group; , compared with the CCI group; , compared with the CCI + EA2D group; , compared with the CCI + EA1W group). Pain score = the paw withdrawal latency (PWL) of the healthy side (right) – PWL of the affected side (left).
