Transcutaneous means "across the skin". In simple terms, a tens machine stimulates your nerves via an electrical current through your skin. What Does a TENS Machine Do? A TENS machine may assist you in modest short-term pain relief. The use of a TENS machine should be as one part of a pain management program under the guidance of your doctor or healthcare practitioner. Your health practitioner should always be consulted before using a TENS machine. How Could a TENS Unit Decrease Pain? Pain is thought to be controlled by TENS in one of two ways: Sensory Level Stimulation - The Gate Control theory of pain means that the electrical input of the TENS machine interferes with the transmission of pain signals, by blocking the neural “gate” through which the pain travels. Motor Level Stimulation - The goal of motor level stimulation is to cause the release of the body’s own opiate-like substances to achieve pain relief. Basically, this is the easiest treatment machine at home. But i cant cure the cause. Today we have much more deeper penetrating rays like tecar and laser.
