These devices can help the consumer relieve the pain almost instantaneously, and you won’t even have to do any lengthy procedures. We have been reviewing the best TENS unit for a long time to share with you only the best results.

What is the TENS Unit?

It is a battery-powered device that delivers high or low-intensity electric pulses via electrodes attached to adhesive pads to a person’s skin. TENS is a short form of Transcutaneous Electrical Nerve Stimulation.

These electric impulses pass through your skin and flood your nervous system, which loses its ability to send pain signals to the brain or spinal cord.

The electric pulses stimulate the body so that it starts producing endorphins – which are known as natural pain relievers.

When you are feeling pain, it’s your nervous system that transmits pain signals. These electric pulses won’t let the nervous system do this job. Instead, these pulses stimulate the body to produce pain relievers. Thereby, when you use a TENS unit, then it offers instant pain relief.

When to Use a TENS Unit?

You can use this portable therapy device when experiencing pain in your back, neck, and joints. Many women get pain relief through tens units during labor and period pain. This device works great for people dealing with medical conditions such as arthritis, fibromyalgia, spinal cord injury, multiple sclerosis, and endometriosis.

When to Avoid a TENS Unit?

If you have a heart problem or a pacemaker, or a metal implant of any kind, please don’t use this device. Pregnant women should never use it.

Never place electric pads on your neck. If you do so, it will cause spasms and lower your blood flow. Another place not to put these pads is your eyes as it may cause injury by increasing pressure on your eyes.

Are there any side effects of tens unit?

You may feel a tingling, buzzing, and trickling sensation while using this device, but you will get used to it. Some people experience redness and irritation in the place where they set adhesive pads. If you encounter the same problem, try using hypoallergenic pads. 

Does TENS Unit Work? Is it really effective? Research

TENS Unit isn’t studied much during high-quality clinical trials or medical research. So, there isn’t enough evidence regarding the effectiveness of this machine. 

Although there is a lack of medical evidence that explains the unit’s effectiveness, some factors make you consider this electric therapy to deal with pain relief.

People taking opioids can find more benefits from a high-Frequency HF TENS unit. According to a review https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4186747/pdf/nihms620660.pdf, HF unit works better than an LF unit.

Another thing to note is that this therapy works great and effectively only when electrodes are placed directly at acupuncture points. 

TENS Units for Back Pain

Back pain issues are pretty common among people all around the globe. So, when it comes to its solutions, people use painkillers, therapies, meditation, and stretching. Pain medications make you addicted in the long run, so you need to rely on a TENS unit that works as a supplement.

It offers temporary back pain relief. If a person starts using a TENS unit regularly, he can depend less on pain medications and more on TENS units. When you use this electrode therapy, it reduces your focus from pain up to 30-40 percent when the machine is on and almost 5-10 hours afterward.

Does TENS Unit work effectively for Back Pain?

Two theories support the use of TENS units during back problems. Let’s find out more about them.

  • The Gate Control Theory: As soon as you experience back pain, it activates smaller diameter pain fibers. For getting relief from this pain, you turn on your Low-frequency TENS unit that stimulates large-diameter pain fibers. Your brain doesn’t get signals from tiny fibers as large fibers are active. It’s a way of diverting brain signals through electric pulses.
  • The lesser of the Two: According to this theory, when you turn on your High-Frequency TENS unit, electric pulses stimulate your body’s nerves that start releasing local neurotransmitters known as endorphins, which block pain signals. 

TENS Unit for Chronic Pain

Chronic pain is defined as pain that lasts for three to six months and after passing the expected healing period. Many people get relief from this pain through the regular use of TENS units.

You should use this unit for at least 30 minutes to get some great results. It will work for you when you are active. It won’t work effectively when you are lying down, resting, or sitting still.

How Long Should You Use a TENS Unit?

If you have muscle spasms, you can stimulate your muscles with this unit for almost 10-15 minutes when you experience total spine pain like tension in your lumbar, cervical and thoracic parts.

It’s better to use this machine for up to two hours on every part for getting better results.

Is TENS Unit Work for Everyone?

The way you respond to this therapy depends on your medical condition, pain level, and other personal characteristics. Some people don’t respond well to this therapy, while other experience ultimate pain relief to the extent that they stop relying on pain medication too much.

If this unit works for you, you can focus on your routine life and keep this handy device with you. Whenever you experience some pain, you can start treating yourself. No need to take a pill every time to feel better. You can resume and improve the normal functioning of your life through regular use.

Is it safe to use the TENS Unit?

Yes, it is safe to use this unit as long as you know how to apply adhesive pads correctly. If you place pads improperly, it may cause electric burns on your skin or lead to skin irritations. Please don’t set these pads on some areas where you feel numbness, as you may burn yourself by doing so.

Unsure how to use it? Do this therapy under the supervision of a doctor or physical therapist to prevent side effects and get desirable results.
