Electrotherapy involves the use of direct or alternating current for therapeutic purposes. The most commonly used are galvanic current, diadynamic current, interference currents and Russian currents. Transcutaneous electrical nerve stimulation (TENS) has a special analgesic effect, which can be used for pain relief in the most severe diseases.

Interference currents can also be applied to segments where there is osteosynthetic metal material.

The most important therapeutic effects are:
A) pain reduction and relief
B) improving local circulation
C) improvement of local and general metabolism
D) reduction of swelling
E) improving tissue elasticity
F) overcoming contractures, limited mobility (bone, muscle, skin)
G) preventing the formation of scars
H) stimulation of bone healing
I) regulation of the tone of the sympathetic and parasympathetic nervous systems
J) functional recovery after deprivation or immobility
K) improving respiratory function and heart function.

The duration of these procedures is from 6 to 30 minutes.
