Local transcutaneous electrical stimulation (TENS) effects in experimental inflammatory edema and pain.

Few studies in the literature associated transcutaneous electrical stimulation (TENS) use with an antiinflammatory activity. The purpose of this study was to investigate the effects of low (10 Hz)- and high (130 Hz)-frequency TENS on hyperalgesia and edema that occur after injection of carrageenan in rat paw. After induction of inflammation, either low- or high-frequency TENS was applied in the rat paw for 20 min, and the effect of TENS treatment on escape or paw withdrawal and edema was measured.
