[Electrotherapy].

Abstract

Physical therapy offers various modalities of treating back pain, one of them is electrotherapy. Besides the long known, low-frequency currents (galvanization, iontophoresis, impulse galvanization, diadynamic currents, TENS), medium-frequency currents (interference current) are increasingly applied today, as they cause patients to a far lesser degree to experience the often unpleasant "sensation of current". In chronic pain, short and microwave treatment (high frequency), which are to be counted among the thermal therapies, have again and again proved to be beneficial.
