What should you know about an OBI TENS unit?

TENS stands for transcutaneous electrical nerve stimulation. Adhesive electrode pads are placed on intact skin near, rather than directly over, the painful area. The device settings control the pulse pattern and intensity. You should feel a noticeable tingling, not a painful shock.

TENS may change how pain signals are processed, but it does not identify or correct the underlying cause. Relief varies, and a device should not delay assessment of new weakness, injury, infection, or unexplained pain.

Read the manufacturer instructions, check the leads and pads, and begin at a low intensity while seated. Do not place electrodes over broken or infected skin, the front of the neck, the head, or across the chest. Keep the device away from water and remove it before sleeping unless a clinician specifically advises otherwise.

People with a pacemaker, implanted electrical device, reduced sensation, epilepsy, pregnancy, or significant skin problems should obtain medical advice before use. Replace pads when they no longer adhere and stop if burning, dizziness, worsening pain, or skin damage occurs.

Seek medical assessment for severe or rapidly worsening pain, new numbness or weakness, loss of bladder or bowel control, fever with a painful area, or pain after a serious injury. Stop TENS and seek advice for a burn, persistent rash, palpitations, or unusual symptoms during stimulation.

Is TENS suitable for the cause and location of my pain? Where should the electrodes go, and which settings are reasonable? Could my medicines, implanted device, pregnancy, or skin condition affect safe use?
