Different types of electric current are used depending on the purpose of application.
The currents have a pronounced:
The most commonly used types of current for electropy in practice are TENS (transcutaneous electrical nerve stimulation), Interferencing current and low frequency currents
TENS - This indicates the application of electrical impulses through the skin that suppress the transmission of pain in a nervous path. The method is widely used due to its good tolerability, safety and easy application. frequencies in the range 1 -200Hz are used.
Interference current The interference current decreases to the medium frequency currents, which are widely used due to their therapeutic effect, good tolerability and penetration.
The interference current is obtained on the principle of the interference of the waves, in which a third average frequency current is obtained from two medium frequency currents, with a frequency of the difference between the two, which acts in depth of the tissues.
Depending on the frequency, it can be said that the lowest frequencies up to 50Hz act as a stimulus to the muscles, and 50-100Hz are associated with the analgesic effect.
Low frequency currents -For therapeutic purposes, a direct and variable low frequency current with a frequency of up to 800 Hz is used.
Different current parameters such as shape, frequency and modulation of impulses also determine its specific effect on the body.
In general, low-frequency currents are divided into analgesic currents for muscle stimulation and currents for pulsed galvanization.
Analgesic currents are used in muscle, joint and neurological pain, and the most common in practice are diadynamic currents.
Muscle stimulation currents are used to strengthen weak muscles due to immobilization, neurological dysfunction such as paresis, paralysis and more.
Pulse galvanization is based on galvanic current and is used for electrophoresis, improved blood circulation and the removal of edema.
