Within the scope of physical therapy and for pain relief, patients may be treated by electric current, the so-called electrotherapy. (Other terms include stimulation or fine current therapy.)
In addition to manual therapy, electrotherapy is used primarily to loosen muscles and to promote blood circulation within the joints and muscles. Such stimulation can improve healing processes and reduce pain.

The form of electrotherapy is particularly suitable for patients who have pain in the joints and muscles and for patients who have had illnesses or accidents and, as a result, a limitation of the musculoskeletal system or the peripheral nervous system is experienced.

Electrotherapy can also help with paralysis, chronic inflammation, non-activated osteoarthritis and muscle pain.

Electrotherapy is not suitable for patients with a cardiac pacemaker, patients with metallic implants or women with hormonal IUDs in their bodies or who have an early pregnancy.
