Electroacupuncture (EA) has been proved to be effective in treating certain neuropathic pain conditions. The mechanisms of pain relief by EA are not fully understood.

However, information about possible systemic changes in the PNS and CNS after nerve injury is scarce. ⋯ Sciatic neuralgia, cobra venom, demyelination, electroacupuncture, pregabalin, rat model.
