TENS Unit Therapy (Transcutaneous Electrical Nerve Stimulation)
A drug-free option that uses mild electrical pulses through skin pads to help manage certain types of pain.
Treatments & therapies
What it is
A TENS unit is a small, battery-powered device connected to adhesive pads placed on the skin. It delivers low-voltage electrical pulses that may reduce how pain signals are felt and may encourage the body’s own pain-relieving responses. It is usually used alongside other treatments, not as a cure.
Who it may help
- Some types of chronic nerve-related (neuropathic) pain, such as certain neuropathy symptoms
- Neck or back pain with muscle tension
- Some musculoskeletal and post-injury pain
- Patients looking for a non-medication option to add to their care plan
Results vary from person to person, and TENS does not work for everyone. Your neurologist will tell you whether it is appropriate for you.
What to expect
Your clinician shows you where to place the pads and how to adjust intensity to a comfortable tingling sensation — it should not be painful. Sessions often last 15–30 minutes. If it helps, you may be shown how to use a unit at home.
Safety & who should not use TENS
- Do not use if you have a pacemaker, implanted defibrillator or other implanted electronic device unless your cardiologist or physician approves
- During pregnancy, do not place pads over the abdomen, pelvis or lower back unless directed by your obstetric clinician
- Never place pads on the front or sides of the neck, over the eyes, on the head, or across the chest
- People with epilepsy should not place pads on the head or neck and should discuss TENS with their neurologist first
- Avoid broken, irritated or numb skin, areas with known cancer, or areas with a known blood clot (DVT)
- Do not use while driving, operating machinery, sleeping or in water
