Joint, muscle, tendon pain or discomfort... and even cramps: Biopiezo comes from research in electrotherapy to quickly and naturally relieve the "mechanical" discomforts of the locomotor system. The head of the Biopiezo consists of 36 golden points with fine gold, which, applied to the area concerned, send a flow of electrons, stimulating the peripheral nervous system. The message is transmitted to the central nervous system and leads to the massive production of endorphins in the brain. Endorphins, or endomorphins, are endogenous opioid compounds secreted by the pituitary gland and hypothalamus during strenuous physical activity, excitement, or pain. They are similar to opiates in their analgesic ability and to provide a feeling of well-being. They exert immediate relaxing and anti-inflammatory effects. Directions for use: Turn on the device (turn the wheel on the right of the device). Select the lowest degree of intensity with this dial. Place the Biopiezo on the sensitive area. Stimulate by making slight circular movements. Adjust the degree of intensity as and when, preferably gradually during the application or several successive applications. Also adjust the pulse frequency (3 levels) for even more comfort, thanks to the button on the left of the device. The application is recommended over a period of 3 to 7 minutes depending on the need.
