How Does a TENS Unit Work?

TENS units send electronic pulses into your nerves. Do not worry; the pulses are very small in size. You will not be electrocuted.

Most devices come with patches which are attached to the skin. These patches have electrodes which pass on the current to your nerves. The device will provide a tingling sensation, which feels similar to a massage.

The electronic pulses reduce the pain signals to the spinal cord and brain, which may help relieve pain and relax muscles.  It may also help to stimulate the production of endorphins, which are the body’s natural painkillers.

It takes a little getting used to at first. When used as per the manufacturer’s instructions, Transcutaneous Electrical Nerve Stimulation can provide safe and drug-free pain relief.

What Should I look for When Buying a TENS unit?

Before you purchase a TENS unit, it is worth doing a little research. Without this information, you cannot tell if a TENS unit will be right for you. Once you know what a TENS unit does, you will be able to understand how it can begin to impact your life.

Ease of Use

Some TENS machines are easier to use than others? How intuitive are the controls? Can they be mistakenly adjusted when in use? Do you prefer buttons, knobs, or a touchscreen? Does it use batteries that need to be replaced or are they rechargeable?

The Display

Does the TENS unit have a display? Is it too big or too small? Is the screen clear and readable? Is it backlit? Are the controls labelled clearly?


Check what comes with your TENS unit. Does it come with spare electrodes? Spare batteries? Rechargeable batteries? Gels? A case?  You may need to purchase some TENS unit accessories.

Number of Channels

If possible, you want a device with more than one channel.  This allows you to treat different parts of the body at the same time.

How Often Can You Use a TENS Unit?

As we discussed, there is no real threat to using a TENS unit for a prolonged period. This means that there is no real threat to using a TENS unit multiple times throughout your day. A TENS unit can be used as many times as you deem necessary.

TENS units are designed to provide immediate pain relief to the user. If you have pain, then it is a good time to use the device. TENS units also release your endorphins, naturally killing the pain in your body. The way we see it, there are benefits to using it as much as you want to.

  • If you are pregnant, or believe that you may be pregnant it is important that you speak with your doctor before using one.
  • If you have epilepsy or a heart issue.
  • If you have a rash, wound, or sore skin, you should not use the device on that area.
  • If any skin condition develops while using the device, you should stop use immediately, and consult your doctor.  (Note: If you have sensitive skin you could use these pads that are latex-free and non-irritating.)

Is a TENS Machine Worth It?

Yes, TENS machines can make a big differnce in your pain levels which can be priceless.  Also keep in mind that there is a wide range of TENS devices on the market and some are quite affordable.

TENS vs EMS: What is the difference?

TENS and EMS machines have different purposes:

  • TENS stimulates your nerves, keeping pain signals from reaching your brain.
  • EMS contracts your muscles, strengthening them.

Is a TENS and EMS combination unit worth it?

Yes as long as it is in line with your budget and you want to relieve pain and strengthen muscles.  You get the benefits of two treatments from one machine.  The TENS and EMS combination devices tend to be a little higher in price but do offer great versatility.  The TENS function to relieves back pain and the EMS settings help strengthen their muscles.

How do I know where to place the pads?

Pad placement for the TENS unit is key.  In general, you need to put the pads where you feel the pain, but there may be additional areas where you can also use the TENS unit.  We recommend discussing the position of the pads with your doctor as it will be different for each individual.

7 Reasons to Buy a Tens Machine

If you’re on the fence about whether or not you should buy a TENS unit.  Consider these reasons:

1. Pain Relief
Muscle pain can be relieved with electrical impulses. Anywhere there is access to a muscle, like the back, arms, or legs, a TENS unit can be used. So, how does this work?

Well, the body reacts to the impulses to release endorphins. Endorphins are the body’s natural painkiller. All you are doing is prompting your body to send these painkillers out. The best part? There are no nasty side effects.

2. Nerve Retraining
If your body suffers nerve damage, those nerves can become damaged, leading to pain and loss of movement. The nerves become unable to send the needed signals to your brain to request endorphins. TENS units can help to retrain nerves through electrical stimulation, leaving them working as they should.

3. Massage
If the intensity of the unit is high enough, the TENS unit can provide massage to the muscles below (some units are specifically built to do this through EMS). What could be better than relieving pain and retraining nerves while receiving a relaxing massage?

4. Ease of Use
When you buy a TENS unit, you are essentially investing in a medical tool. One which will change your life. One of the greatest things about one of these units is how easy they are to use. Press a few buttons and let the machine do the rest.

5. Reduced Inflammation
If muscles are inflamed, the inflammation will no doubt be accompanied by pain and discomfort. A TENS unit can greatly reduce inflammation.

6. Affordable Treatment 
A TENS unit is an investment, but as investments go, it is an affordable one. If you are managing pain with medication or visits to a medical professional, your bills will be increasing and increasing. A one-time investment in a TENS unit can give you the same relief at a fraction of the cost.

7. Quick Rehabilitation
When you suffer from pain, the simplest tasks can become daunting and often impossible. You want the quickest and safest recovery possible. A TENS unit can be used whenever and wherever. No need to schedule appointments and wait a week between them. A TENS unit may be the best purchase you ever make.
