TENS One is an accurate and versatile, digital TENS unit that is easy to use and designed to provide drug free pain relief from a wide range of conditions. Having recognized that potential users of this unit might be suffering from motor difficulties, we have designed the unit with simple settings and rotating strength control knobs which provides easy drug-free pain relief to those who struggle the most. The way TENS One unit works is pretty simple. It blocks the pain signal from reaching one\'s brain, instead releasing endorphins (hormones of happiness) and thus dealing with the pain drug-free, using nothing but electric current. TENS One is intended for the relief of pain associated with sore or aching muscles of the lower back, arms, or legs due to strain from exercise or normal household and work activities. Additionally, it has an open circuit system integrated, which means if the electrode does not have full contact, the power will be cut off automatically. Our TENS unit 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. SKU: K-TENSONE
