What should you know about a TENS therapy device?

TENS, or transcutaneous electrical nerve stimulation, uses a small controller and adhesive pads. The pulses can change the way pain signals are experienced, often producing a steady tingling sensation. Some people use TENS before or during movement so that prescribed activity feels more manageable. Relief is variable and may stop when the device is removed; the device does not diagnose an injury or correct every source of pain.

The choice of programme depends on the painful area, skin sensation, movement goals, and medical history. A healthcare professional can help decide whether it belongs in your treatment plan.

Request clear instructions for pad placement, intensity, and session timing. Clean and dry the skin, attach pads securely, and increase the intensity only until the sensation is strong but comfortable. Switch the unit off before touching or moving the electrodes. Keep pads away from broken skin, the front of the neck, the head, and directly across the chest. Avoid using the device in water, during sleep, while driving, or near machinery. Pair symptom relief with the rehabilitation exercises and pacing advice provided for your condition.

Stop using the device if it causes burning, lasting redness, a rash, sharp pain, faintness, or an unusual heartbeat sensation. Seek urgent care for new severe weakness, chest pain, trouble breathing, loss of bladder or bowel control, or pain following serious trauma. Arrange an appointment if symptoms are progressing, repeatedly interrupting sleep, or limiting walking or arm use. Tell the clinician about implanted electronic devices, pregnancy, seizures, circulation problems, or reduced sensation before treatment.

Ask what the device is intended to help, where each pad belongs, how you will judge whether it is useful, and which warning signs require a call or examination. Confirm whether your medicines and medical devices affect its use.
