What should you know about TENS 7000 Digital?

A digital TENS unit is a small controller connected to adhesive electrodes. It sends low electrical stimulation across the skin, commonly producing a rhythmic tingling. The display and controls may help you select a programme or adjust intensity, but a digital setting is not automatically right for every injury or pain pattern. TENS may influence pain signalling and can be one part of a broader plan that may include movement, rehabilitation, rest, or treatment of an identified condition. It does not show what is causing pain and should not delay an examination when symptoms are new or changing.

Inspect the wires and pads, wash and dry the skin, and follow the supplied instructions for connecting the leads. Have a clinician show you the electrode positions if you are unsure. Begin with the lowest comfortable level and change one control at a time so you can recognise how your body responds. Turn the unit off before touching the electrodes. Keep pads away from the eyes, mouth, front of the neck, and broken or inflamed skin; do not position them so current passes across the chest. Do not use the unit in water, while asleep, while driving, or when you cannot monitor your skin and sensation.

Discontinue stimulation if you notice burning, a rash that persists, swelling, troublesome dizziness, a racing or irregular heartbeat, or pain that becomes clearly worse. Seek urgent care for sudden weakness, new difficulty speaking or breathing, loss of bladder or bowel control, severe pain after trauma, or rapidly spreading numbness. A planned review is sensible when pain has no clear explanation, interferes with sleep or function, or continues despite the advised programme. Ask before use if you have an implanted electronic device, altered sensation, epilepsy, pregnancy, or a significant skin condition.

Ask which digital programme and intensity suit your symptoms, where each pad should go, and how to space sessions around exercises or other treatments. Check whether your medicines, implants, pregnancy, reduced sensation, or skin condition change the safety advice. Ask how to recognise an electrode reaction and how to replace or store the pads.
