The 3 Best Small & Wireless TENS Units for Back Pain (2017 Reviews)

small wireless tens therapy units for back pain

TENS units are one of the most popular drug-free, non-invasive and non-addictive ways to continuously relieve back pain whenever and wherever you need to.

Small, wireless TENS machines allow you to use your TENS unit with a remote control – without attaching any wires to the electrodes, and without any wires hanging out of your pocket.

But:

With so many wireless TENS units available (and so many technical terms) it can get pretty difficult finding the best wireless TENS units for back pain.

To make your life easier and reduce your research to minimum, we’re created this easy guide to help you make the right choice, no matter if you’re looking for your first Transcutaneous electrical nerve stimulation unit, or wanting to upgrade your current one.

What is a TENS Unit and How Does it Relieve Back Pain?

Did you know? The physician to the Roman Emperor Claudius in AD46 was the first to document that standing on an electric fish could relieve some symptoms of pain (Walsh, 1997).

Luckily, these days you don’t need to go fishing.

Thanks to technological advances, we’ve been zapping ourselves in some form for decades.

A TENS unit (an electric stimulation unit) delivers low-voltage, non-painful electrical pulses via electrodes placed directly onto the skin around the area of pain.

These pulses control pain signals in the body, creating temporary (from 5 minutes to 18 hours) relief from pain.

They can control abnormally excited nerves and release endorphins – natural pain relieving hormones.

TENS units differ in frequency and intensity.

Through my research I’ve found that low-frequency TENS may take longer to relieve pain, but the relief will last longer than using high-frequency TENS machines.

The frequency of the currents coming from a TENS unit can be turned up or down, ranging from about 10 Hz to 50 Hz. Most TENS sessions last from 15 to 30 minutes and can be administered as often as needed.

Now:

Why go for wireless units?

Benefits of Wireless TENS Therapy Units (vs. Wired)

Wireless and portable TENS units are a great fit for people with an active lifestyle, who need this drug-free on the go pain relief tool to not interfere with their day.

  1. With a wireless TENS machine, which runs on batteries, you won’t need to attach cables to electrodes and plug them into the machine.
  2. You don’t need to find a wall receptacle to plug it into
  3. You can conveniently and discreetly wear them underneath clothing – without anyone else seeing them (or the wires hanging outside your pocket) – for a quick back pain relief.

All you have to do is switch your TENS device on with the remote – whenever you need it.

Note: make sure to check with your physician to make sure TENS treatments are right and safe for you.

  • Doesn’t come with a remote, a bit difficult to adjust intensity when placed on your back, but the + and – buttons are raised you can find them when you feel your way around.

3. Hollywog WiTouch Wireless TENS Unit

The WiTouch portableTENS machine covers a relatively large treatment area and comes with a wireless hand-held remote control and 10 reusable replacement pads.

What we like about the WiTouch TENS unit:

  • Automatically starts on a low intensity level when turned on
  • The pads that this unit uses are very strong, and the device stay on for hours, if not all day
  • Larger treatment area than the other 2 TENS on this page

  • Comfortable for all situations – sitting, moving around etc.

What we didn’t like:

  • Auto shut off after 30 minutes (but can be re-started without waiting)

  • Price is relatively higher (but the pads last longer and so does the battery, so everything evens out in long term use)

Wireless TENS Units Safety and Side Effects

Wireless TENS machines are available without prescription and are generally safe to use, if the device is not faulty.

Consumer TENS units are too weak to be dangerous and the risk of a mild shock is extremely low.

However:

There are a few things you should know before you start electrotherapy:

  1. Overdoing it can cause some skin irritation around the electrodes.
  2. Pregnant women and people with heart conditions should avoid using it.
  3. People with infusion pumps, pacemakers, defibrillators or similar devices should not use a TENS unit for back pain.
  4. People with implanted medical devices containing metal should also avoid TENS therapy.
