Electrotherapy represents the use of electrical energy or impulses in order to activate and stimulate natural processes of healing in the body. Electrotherapy found its use in medicine with the help of the discovery of positive effects on the muscle and nervous system. Electrotherapy can be divided into direct and indirect. Direct electrotherapy consists of: galvanization, diadynamic current, interferential current, electromagnetic therapy, ultra stimulation current, high frequency current, and the indirect one consists of all the methods that transform electricity into another source of energy that is used for therapeutic purposes , such as light energy, heat energy and mechanical energy (ultrasound, laser, heat wave, etc.) When it comes to chronic illnesses, post-operative recovery or taking care of an acute injury, electrotherapy is mixed with an array of other physiotherapeutic techniques, ranging from therapeutic exercises, massages, laser, ultrasound, etc. Only such a complex approach gives best results. This is how contemporary therapy has found its place as a meaningful component of the physiotherapeutic process.
