Transcutaneous Electrical Nerve Stimulation (TENS tens transcutaneous electrical nerve stimulation ) is a non-drug and non-invasive pain relief method.
The sensory nerve is stimulated by a mild and trace amount of current (usually no more than 25 microcoulombs per unit time) to block the transmission of pain nerve signals to achieve analgesic effect.
Clinical studies have proved that the dysmenorrhea pain-relieving instrument made of TENS principle is effective for the treatment of dysmenorrhea, and it is a method to replace the pain of medicine. Because it is non-invasive and has no side effects, it has been popularized and applied in European and American countries.
