The effects of pretreatment of muscarinic cholinergic receptor agonist (neostigmine, EA+NSTM, n = 10) and antagonist (atropine, EA+ATRP, n = 10) in the CIOA rat treated by 2 Hz EA (EA+DMSO, n = 10) assessed by TFL (a) and PPT (b). DMSO, NSTM, and ATRP were pretreated 20 min before 2 Hz EA. *p < 0.05, **p < 0.01, ***p < 0.001: compared with EA+DMSO
