From arthritis relief to frozen shoulder treatment, our Perfect TENS unit grants pain relief with the touch of a button. Small but powerful, the Perfect TENS unit comes with two separate channels and 8 preset and 1 manual pain relief programmes, each with its own combination of settings to suppress pain in different ways. The unit is so small and light you can take it anywhere and comes with lead wires, self-adhesive electrodes and batteries, making it available to use immediately. When the electrodes are placed on the skin, they deliver small electrical impulses to stimulate the nerves in the affected area. The pain relief comes because TENS acts by blocking pain signals from reaching the brain. In addition, TENS stimulates the body to produce its natural pain killers endorphins. Back pain, arthritis or even period pain all can be tackled by a session using Perfect TENS. Perfect TENS is scientifically proven to provide safe and effective drug-free pain relief and is approved for use in the UK and worldwide by the NHS, EU and FDA. Additionally, it has an open circuit system integrated, which ensures that if an electrode is not attached correctly to the skin , the strength automatically resets to zero. SKU: K-PERFECT
