Healing power - electrotherapy


Electricity, which children learn early, is dangerous. Because in case of accidents with electric current can cause heart rhythm disorders: muscles, including the heart, cramp together. There is less or no blood and thus too little oxygen transported in the body. This condition can lead to death within a few minutes. On the other hand, electrotherapy is very gentle: muscle contractions are specifically brought about by passing current through the body through electrodes that are stuck to the skin. In this way, electrotherapy, also called stimulation current therapy, is used to treat pain, discomfort and to strengthen weak muscles.

TENS stimulation current therapy

For over 30 years, doctors and physiotherapists have been using Transcutaneous Electrical Nerve Stimulation (TENS). A low-frequency, low-frequency alternating current (measured in hertz / hz), which is used primarily for the treatment of pain and muscle stimulation. The frequency is 10 to 100 Hz.

The electrodes are placed near the painful areas. The stimulus itself is not painful - you may feel a tingling sensation on the skin. Sometimes the electrodes are placed in the area of ​​the spine from which the affected nerve emerges. These skin areas are then stimulated with high frequencies and low currents and trigger non-painful sensations. Thus, a counter-irritant is created and the pain improves.

In principle, stimulation current therapy serves to strengthen the musculature. For a successful treatment, a daily treatment of 30 minutes is recommended over a period of at least six weeks.

Principle of counter irritation

As in acupuncture, the principle of stimulation current therapy is called counter-irritation: The actual pain stimulus should be reduced by means of a local touch or vibration stimulus.

Very often patients report an improvement in many chronic pain disorders. These include muscular rheumatism, neuralgia such as sciatic pain, osteoarthritis, and even paralysis is diminished by the stimuli. Even with muscle weakness and lack of muscle sensation, lack of circulation through circulatory disorders, bone disease as a result of accident damage and arterial occlusive diseases, the electrotherapy is indicated.

Phlebitis, decubitus ulcers, delayed wound healing, osteoporosis and delayed bone healing are other applications of electrotherapy.

Electricity and water: The Stangerbad

Electricity and water - a really dangerous combination. But that too can be beneficial. At the beginning of the 20th century, the master jug ​​Johann Jakob Stanger from Ulm developed a so-called hydroelectric bath, which today is mainly used for chronic articular rheumatism, neuralgia and ankylosing spondylitis (an inflammatory chronic disease of the spine). The DC current flowing through the body provides muscle relaxation and stimulates muscle and nerve activity.

The patient sits down in a tub, in the side walls are large, plate-shaped electrodes embedded: two left and right and one head and one foot electrode. This arrangement allows the current to flow through the body in different directions - very gently.

The circuit depends on the indications. Thus, in rheumatic diseases, a descending, ie a running in the body from top to bottom, current direction is selected. This is intended to reduce the excitability of the nerves and the muscle tension. In paralysis, on the other hand, ascending currents try to stimulate muscle and nerve activity. By using DC and the very high safety standards, the Stangerbad is completely harmless.

For cardiovascular diseases and the lungs, however, this therapy is not suitable. The Stangerbad is part of the electrotherapy for DC therapy, also called galvanization. Galvanization is basically used for pain relief and blood circulation promotion.


Improved blood circulation, pain relief and increased metabolism are the effects of ultrasound. Also this application counts in the broadest sense for the electrotherapy.

Ultrasound is also known as micro-vibration massage: electricity, converted into high-frequency mechanical vibrations of about 1 Mhz (vibrations), the patient does not feel is applied via a transducer with a contact gel on the diseased region and thereby moved in a circle.

This application can also be used in a sub-tub or container underwater, such as feet and hands. The sound is emitted continuously or pulsed. The pulsed sound produces less heat effect.

Shortwave therapy

Electrotherapy also includes short-wave treatment (diathermy). She works with waves in the high frequency range. This electromagnetic energy generates heat. Through deliberately applied warming to 40 to 41 degrees Celsius, the blood supply in the tissue increases and it begins the healing effect.

According to the Ärztezeitung, suitable devices can also be used to reach deep tissue if the performance of the devices is high enough and the electrodes can be placed one to two centimeters away from the body site to be heated. In particular, rheumatic diseases, but also diseases of the musculoskeletal system, the muscles and the skin and in certain forms of Turmorbildung the shortwave therapy has shown good results. Patients with muscle and soft tissue pain such as tension can also benefit from shortwave therapy.

The duration of use is between six and twelve treatments of ten to 15 minutes with different heat dosages.

Application at home possible

While ultrasound, shortwave therapy and Stangerbad by physiotherapists or in health clinics is offered, you can also apply the TENS well at home. The device for electrotherapy is about the size of a cigarette box, is driven by a battery and the electrodes used are only a few square centimeters.

Before use, the doctor explains how high the current should be, how often and at which point it is used. You stick the electrodes directly over the painful area or to the places indicated by the doctor. Then you choose the current so that feel only a slight pleasant tingling sensation.

Three to four treatments a day for half an hour are usually sufficient. After a few weeks, the effect may subside, then you should take a break or use the electrodes in other places. The prescribed by the doctor applications of electrotherapy are considered remedies and are paid by the health insurance. The device is rented, usually it is sent back to the manufacturer after treatment.

The electrical stimulation is almost always very well tolerated and almost free from side effects. Caution should be exercised only with pacemakers or larger metal implants. In individual cases, skin irritations, epilepsy, aversion to electricity and mental pain syndromes may speak against the use of TENS.
