Observing the parameter-specific anti-hyperalgesic effects of EA with different stimulation times and frequencies on painful hyperalgesia mediated by the level of TRPV1 and P2X3 expression in DRG after CFA injection. ⋯ EA has a parameter-specific effect on chronic inflammatory pain relief, which primarily depend on the stimulation frequency and not on the stimulation time at a certain stimulation time. The parameter-specific analgesic effect of EA is at least partially related to mediation of the protein level of TRPV1 and P2X3 expression in DRG of CFA rats.
