Effect of BoNT-A on mechanical hypersensitivity induced by ION-CCI. Rats underwent either ION-CCI or sham operation. Fourteen days after the operation, BoNT-A (3, 10 U/kg) or normal saline was injected into the whisker pad ipsilateral to the operation site. Measurement were performed on the ipsilateral to the nerve injury. *P < 0.05 versus control group and #P < 0.05 versus CCI group
