Our nerves, which radiate throughout the entire body as a complex network, perform various tasks which are indispensable for maintaining proper functioning. They conduct impulses between the central nervous system and an organ or a part of the body. They also transmit commands from and to the brain, and they regulate the body functions, as well as muscle contraction and relaxation. Using the TENS method, Transcutaneous (i.e. passing through the skin) Electrical Nerve Stimulation, the important nerve functions can be activated effectively. The frequency impulses, which are comparable to the natural bioelectricity, stimulate the body pain-relieving mechanisms. In this way, the transmission of pain by the nerve fibres is inhibited and secretion of pain-relieving, morphine like substances such as endorphins, are triggered. Furthermore, the blood flow through the treated body zones is improved. For active people, it provides a massaging experience which has a very beneficial effect on muscle and shoulder or neck stiffness. It is very good for soothing overall bodily fatigue and improves the blood circulation in the treated areas.
