TENS stands for Transcutaneous Electrical Nerve Stimulation and is recognised as a safe method of easing pain. TENS treatment is recommended by doctors, physiotherapists and pharmacists. The mini TENS works by passing harmless electrical signals into the body from the gel pads (controlled by the user). This eases pain by blocking the body's pain signals. These are normally transmitted from the area of damage through the nerve fibres to the brain. TENS interrupts these pain signals. TENS stimulates the body's production of endorphins, its own natural painkillers. Please read the enclosed user manual carefully before use. Can be used alongside medication.
