Electrotherapy Devices

Electrotherapy or electromedicine is the name given to the therapeutic use of electrical current in medicine and physiotherapy. The terms “stimulated current therapy” or “fine current therapy” are also used synonymously in certain procedures. What these processes have in common is that direct current or alternating current flows through the human body or different parts of the human body during use. The corresponding voltage is provided by electrodes that are conductively connected to the surface of the skin, or by electrodes in a water bath. If, on the other hand, the implant is used for functional electrical stimulation, the current transmission electrode is located in the tissue. The procedure (transcranial magnetic stimulation, pulse signal therapy, etc.), in which the magnetic field in the human body generates an alternating voltage according to the law of induction, has a special position.

Depending on the duration of denervation, the muscles respond differently to different types of currents. In general, long-term exponential current denervation treatment with longer triangular pulses can produce the best results because the muscles only respond to longer current pulses. Triangular pulses are used because healthy muscles do not respond to this type of pulse due to their adaptability. Faraday current and square wave current are also used. Constant direct current (called galvanizing) does not cause shrinkage. Electrotherapy (electrical stimulation) is one of the physical therapies. Among other things, it can be used to relax muscles, promote blood circulation, relieve pain, and improve healing. For this reason, physiotherapists usually provide power to the patient through glued electrodes.

The direct current that acts stimulates the nerves in the blood vessel wall to release the body's own vasodilator substances. The blood flowing into the skin can increase by up to 500% and the blood in the muscles by up to 300%. In addition, direct current therapy activates and relaxes the muscles, which is called tuning in physiotherapy. The low frequency treatment is carried out by a so-called pulsed current. Depending on the frequency, the treatment affects the body: In the high frequency range, it has a pain-relieving and anti-inflammatory effect. As with direct current therapy, the low frequency can be used to stimulate blood flow to the skin and stimulate muscle contraction. In addition, low-frequency electrical stimulation can stimulate lymph flow, which stimulates the tissue fluid (lymph) to return to the core of the body.

In intermediate frequency therapy, the therapist uses alternating currents with different frequencies. Like low-frequency therapy, this therapy also has obvious depth effects. In particular, it improves muscle metabolism and increases muscle endurance. Radiofrequency therapy can relax tense muscles. This treatment can warm the tissues, which speeds up the metabolism of the muscles and allows wounds to heal faster. Electrostimulation therapy can also take the form of a bath. In this case, water is used as a conductive medium. To do this, the patient has to sit or lie in a special bathtub in hot water and immerse it with a constant direct current. For example: Stangerbad (full hydropower bath), four-cell water bath (for arms and legs) and partially electric hydropower bath.
