What Is a Nursal TENS Unit?

TENS stands for transcutaneous electrical nerve stimulation. Adhesive electrodes sit on intact skin near, but not directly over, the painful area. The device delivers a controlled tingling sensation that may change how pain signals are processed and may support comfortable movement. It does not repair a torn tissue, remove a fracture, or diagnose the reason for pain.

Response varies between people and depends on the pain pattern, pad placement, intensity, and duration of use. A TENS Unit may be offered as part of a broader plan that includes movement, rehabilitation, and treatment of the underlying condition.

Follow the device instructions and any guidance from a physiotherapist or clinician. Place pads on clean, dry, intact skin; start with a low intensity and increase only to a strong but comfortable tingling. Turn the unit off before moving electrodes. Check the skin after use and stop if there is burning, marked irritation, pain, dizziness, or worsening symptoms.

Do not place electrodes across the front of the neck, head, eyes, or broken skin. Ask a clinician before use if you have a pacemaker or other implanted electronic device, a seizure disorder, reduced sensation, or are pregnant. Do not use it while bathing, sleeping, driving, or operating machinery.

Seek urgent assessment for new severe weakness, loss of bladder or bowel control, numbness around the groin, chest pain, breathing difficulty, or pain after a serious injury. Stop using the unit and seek advice for a persistent skin reaction, electrical shock, or symptoms that are rapidly worsening. Arrange a clinical review when pain persists despite self-care or limits normal activity.

Ask: Is TENS suitable for my diagnosis? Where should the electrodes go? What intensity and session length should I use? Could my medicines or implanted device affect safety? What rehabilitation should accompany pain control?
