iTENS – Wearable Electrotherapy TENS Unit For Pain Relief?


iTENS is an electrotherapy device you can control from your smartphone. Find out how it works today in our iTENS review.

What is iTENS?

iTENS is a “smart” version of a TENS therapy device. Transcutaneous Electrical Nerve Stimulation (TENS) therapy devices are adhesive pads that are placed around your body and use electrotherapy to stimulate your muscles.

If you’ve ever worked with an occupational therapist or physical therapist, then you’ve probably seen TENS devices before. Many people have also been told to use TENS devices after experiencing back pain.

iTENS promises to be a smart version of that device you can control from your smartphone.

This isn’t just some flash-in-the-pan device from a brand new startup company. iTENS has been cleared by the FDA. It’s also the world’s first truly wireless TENS therapy device that can be controlled using an iOS or Android app.

iTENS is available for anybody to purchase. You don’t need a prescription. It’s being advertised as an effective, easy-to-use, drug-free way to combat pain.

How Does iTENS Work?

iTENS works using an easy three step process:

  • Step 1) Peel the adhesive lining off the gel pads
  • Step 2) Place the pads on your pain site
  • Step 3) Launch the Android or iOS app

You can actually use iTENS underneath your clothing. The pads come with thin, lightweight wings that make them virtually undetectable. You can control programs on your smartphone for discreet electrotherapy while you work or run errands.

Another convenient thing about iTENS is that there are no wires. It just fits discreetly underneath your clothing and communicates with the app over Bluetooth.

iTENS Features

iTENS includes all of the following features:

iTENS Products

There are large wing and small wing options available. The small wing options are recommended for treating pain in small or flexible parts of your body, while the large wing options are more suited for areas like your chest or back.

iTENS gives you up to 24 hours of continuous use per charge. Each gel pad is good for 10 to 12 applications before the adhesive coating wears off.

-Small Wings ($99.99): Grip and move easily on your ankle, knee, elbow, wrist, and other small treatment areas. They’re 1.75” x 5.5” in size.

-Large Wings ($99.99): Provide maximum coverage over larger pain sites, like your back, shoulder, or chest. The wings are 2.5” x 6.5” in size.

Both the large and small options come with the same accessories, including:

  • Rechargeable lithium ion battery
  • Laser-printed silver conductive surface
  • Charging dock with USB charging cable
  • One set of reusable gel pads (good for 10 to 12 uses)

You can also choose between different colors. The small wings come in colors like green or yellow, while the large wings come in colors like indigo and silver.

Both the large and small wings promise to provide medical grade strength.

iTENS Accessories

The gel pads you get with your original iTENS purchase will only last for 10 to 12 uses. You’ll need to order replacement strips and gel pads from time to time.

You can buy these replacements from the iTENS online store, where the following items and prices are available:

-Long Strip ($26.99): This can be used with the main iTENS device. You can use the long strip to provide pain relief on areas of your body where the pain radiates downwards.

It’s especially recommended for the sciatic nerve, IT band, tendons, and other longer treatment areas. Each $26.99 package includes a long strip (1.5” x 7”) along with one box of gel pads containing 3 sets of gels.

-Small Wings ($26.99): The small wings accessory is the same used in the full small wings package.

You can use the small wings pad to treat smaller areas of your body, or flexible areas. Each small wing is 1.75” x 5.5” and includes one box of gel pads with 3 sets of gels.

-Large Wings ($26.99): The large wings accessory provides maximum coverage for pain sites and is identical to the one you receive in the large wings iTENS package.

It includes one large wings pad (2.5” x 6.5”) along with one box of gel pads that contains 3 sets of gels.

-Refill Gel Pads ($6.99): These are the reusable gel pads you can use with your iTENS device. Each gel pad is good for 10 applications. Each $6.99 package contains 3 sets of gel pads.

-AC Wall Charger ($6.99): Your iTENS purchase includes a USB charging cable. You can buy this AC wall adapter that contains an AC plug at one end and a USB adapter on the other, letting you charge your iTENS through a conventional outlet.
