Which TENS units are best?

There are many options available for pain control and relief. While pain pills, supplements, massage and other medical interventions may be helpful, many people are trying transcutaneous electrical nerve stimulation (TENS) therapy. TENS is based on the idea that low electrical currents sent to the nerves in areas where pain is present will lead to the creation of endorphins and convince the brain to detect less pain in that area.

Developed in the 1970s, TENS therapy is used around the world by health care professionals and individuals looking for fast, temporary pain relief. Portable, home-based units provide a convenient and safe method for applying TENS to your pain areas. For multiple operating modes and reusable electrode pads, the iReliev Premium TENS + EMS Pain Relief & Recovery is the top choice.

What to know before you buy a TENS unit

Which treatment mode is best for you?

Each person responds differently to TENS therapy. Variables include the part of the body being treated, your own sensitivity to nerve stimulation, and the type of pain that you are experiencing. Many TENS units have multiple treatment modes that focus on the neck, back, abdomen, feet or arms. They also deliver different types of impulses such as shiatsu, kneading, cupping and acupuncture. It will take some experimenting before you find the right mode for your particular pain and specific area of the body. 

Which intensity level is best for you?

Most TENS units have multiple levels of impulse intensity that you control. Some have as many as 20 levels or higher. Each individual responds differently to impulse strength so you will need to start low and work your way up to a therapeutic level. Look for TENS units with digital controls that require you to adjust by pushing a button versus those with dial controls. Digital controls are more specific and prevent you from accidentally bumping a dial.

Who shouldn’t use a TENS unit?

People with pacemakers, and pregnant women should not use TENS units. People with skin sensitivities wishing to use TENS units should take extra precautions to limit skin discomfort. Anyone with other significant conditions like heart disease, infectious diseases or diabetes should consult their health care professional before using a TENS unit.

What to look for in a quality TENS unit


Most TENS units come with a timer function that runs from 5-60 minutes. Look for TENS units with an automatic shut-off feature that ensures you don’t run the unit too long if you fall asleep. Most experts recommend not using a TENS unit for more than one hour.

Dual channel

Some TENS units offer a dual channel feature that allows you to send different impulse levels to different areas of the body at the same time. Your lower back may require more stimulation than your upper back, but dual channel allows you to treat both simultaneously with different impulse intensity.

Electrode pads

One of the most important features of TENS units are the electrode pads that attach to the skin. Pads that stay in place will deliver a much better treatment experience. Since some people are sensitive to the adhesive, you may need to experiment with different types. There are also hypoallergenic pads for sale if your unit’s pads cause irritation. Always make sure that your skin is clean, dry and free of any lotions when applying the electrode pads.

How much you can expect to spend on a TENS unit

Basic one-modality TENS units cost between $20-$25, and midlevel units with digital controls and electrodes are priced between $25-$40. TENS units priced above $40 typically offer the most treatment options and have more electronic console features.


How often can I use my TENS unit?

A. You should limit your TENS sessions to a maximum of three per day. Over time, the body can develop a tolerance to the treatment if it is used too often. Always check with your health care professional if you have concerns.

Does it matter which direction the electrode pads are positioned?

A. There is no right or wrong way to position the electrode pads. Your manufacturer’s manual may have some suggestions. However, you will get different sensations by placing pads closer together or farther apart. You also will get a different sensation by placing the pads vertically, horizontally or diagonally. Over time, you will discover the best position for your body and pain level.

Are there side effects from using a TENS unit?

A. The most commonly reported side effect is skin irritation from where the electrode pads adhere to the body. There are hypoallergenic pads available for people with skin sensitivities.
