How Does a TENS Unit Relieve Back Pain?

A TENS unit (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.

👉 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.

Wireless TENS Machines Pros & Cons

TENS units with no cables are simpler to use (and those with remote control are easiest to use and adjust), they are completely discrete (you can wear them under your clothes), and they are lightweight and highly portable. Cons include fewer programs, less power (some devices), and having to purchase the manufacturer’s own replacement pads.

Lightweight yet sturdy carrying case

The EMS programs are for exercise preparation, post-exercise recovery, building endurance, and strengthening your muscles.

What is EMS?

EMS stands for “Electrical Muscle Stimulation”. This electrical stimulation gently contracts the muscles and helps warm them and activate them to increase strength and endurance and promote recovery – without you having to move at all.

Once the electrode pads are applied to your skin, the electrical impulses activate your motor nerves to send signals that cause your muscles to contract. This is the same natural process you feel when you work out your muscles.

The iReliev is the most versatile wireless TENS machine on this list.

How to Use a TENS Unit for Back Pain & Sciatica

Generally, you should apply the TENS unit directly to the pain area. See the short video below for instructions:

(👉 A TENS unit is one of the best back pain gifts for people you care about)

How Long Does Pain Relief from a TENS Unit Last?

Pain relief duration from a TENS unit can be different for each person. Some people report that their pain returns as soon as they switch off the device. Others continue to feel pain-free for up to 24 hours. A 2012 study suggests that the duration of pain relief increases after repeated TENS treatments. However, this can also increase the chances of a person building up a tolerance to the treatment.

👉 We recommend combining TENS therapy with heat therapy for a complete back pain relief natural treatment. See the best portable heating pads you can wear and use on the go!

Is a Wireless TENS Machine Safe?

Wireless TENS machines are available without a 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.

 How Often Can You Use a TENS Unit in One Day?

Beginners can start with one or two 15-minute treatments per day, and it is recommended to rate the pain reduction after each treatment. However, studies have shown that repeated application of TENS at the same frequency, intensity, and duration daily can reduce effectiveness over time.

We recommend changing treatment time and intensity and altering with EMS modes to prevent your body from becoming used to the treatment and thus less responsive to it.

 Conclusion

TENS has been a therapeutic alternative pain management staple in physical therapy and chronic pain clinics for dozens of years and has a huge following of believers.

We’ve researched and found the 5 best wireless, portable, small TENS units in the market, all of them are reasonably priced and of high quality, and our top pick is the iReliev TENS & EMS machine.
