Innovation in technology has reduced our dependence on drugs for pain management. TENS and EMS units are safe, non-invasive, and drug-free methods to provide relief from musculoskeletal pain. These small, portable devices have been recommended and employed by medical professionals for decades now.
The market is brimming with several varieties of TENS units. Choosing one that suits your needs the best is not an easy deal. This article provides all the information that will help you in your quest . We have listed the 7 best TENS units available on the market right now, along with a buying guide.
What Is A TENS Unit?
Transcutaneous Electrical Nerve Stimulation(TENS) is a small, battery-operated device that is used for pain relief. It involves the use of mild electrical current.
The device features a lead that is connected to small pads known as electrodes. For therapy, the pads are directly attached to your skin. As you switch the machine on, small electrical impulses are delivered to the pain affected areas of your body.
You may feel a tingling sensation as the machine runs. TENS therapy may reduce the pain signal going to your spinal cord and brain, which may help relieve pain and relax your muscles.
TENS machines may stimulate the production of endorphins. Endorphins are the body’s natural painkillers. This machine may help reduce pain and muscle spasms caused by arthritis, period pain, endometriosis, back pain, knee pain, neck pain, and sports injuries.
How Does A TENS Unit Work And Where To Buy One?
To start the TENS therapy, you first need to plug the pad wires into the A and B channels that are located at the top of the device.
- Snap the wire onto the pads for powered muscle stimulation. Ensure that each part is connected firmly.
- Peel off the protective film on the electrode pads and place them on the targeted area of pain relief. The pads have to be placed 3 cm apart, on each side of the desired area to avoid overlapping.
- Once the electrode pads are securely placed, switch on the machine. It will start automatically from mode 1 and level one. You can select the mode of your choice.
- Use the intensity buttons located on the left-hand side of the device to control the A1/A2 ports. For dual channels, alter the intensities on A and B channel (left side/right side).
- Increase the intensity gradually and gently to test your acceptance level of intensity.
- After using the device, turn it off completely and then unplug it. Make sure to keep the pads back into the pad holders to ensure the longevity of the pads.
Though you can buy a TENS machine online, it is best to consult your general physician. This way, you can get a proper assessment done and know whether you need a TENS machine or not. Also, your doctor may refer you to a physiotherapist or pain clinic.
You can first try TENS therapy at the physiotherapy center, and if it works for you and provides relief, you can buy the device.
Getting yourself acquainted with TENS therapy at the physiotherapy center will not only help you in making the purchase decision, but you will also learn how to operate the device. The therapy will be most effective only when the settings are adjusted correctly according to you and your condition.
Let us now take a look at the best TENS units you can buy.

- The conductive pads should only be used on normal, healthy, clean, and dry skin. Never use the pads on open wounds or rashes or over swollen, red, infected, or inflamed skin.
- If you are a first-time user and notice symptoms like red and itchy skin, discontinue using the TENS unit.

TENS units can be easily purchased at local retail stores and on the internet. You have several options to choose from. This might also confuse you, though, as to which one to buy. We have listed below a few important factors that you need to keep in mind to make your TENS purchase decision easier.
Buying Guide – How To Choose The Best TENS Unit
- Modes: TENS units are available with different modes and programs you can use. They offer two types of therapy: predefined massage programs and other units that allow you the possibility to create your own massage program using a combination of their features. Some models of TENS units come with predefined modes and programs for every part of your body. Buying a TENS unit that offers multiple modes and programs will add to your therapy experience.
- Intensity Levels: TENS units offer multiple intensity levels that allow you to personalize your therapy experience. Depending on your needs, you can adjust the intensity of the device on high or low. For a relaxing massage, you can set the device on low intensity, while for a reinvigorating massage, you can increase the intensity. This adjustability feature of the machine does not make it user-specific and can be shared with other members of the family.
- Timer: TENS units come equipped with a timer that makes for safe user experience. This feature also helps to preserve the life of the unit’s battery and that of its electrode pads. The timer helps you time your session. Using the unit for too long can be uncomfortable and may lead to bruising if you have no previous experience of using the unit. On the other hand, shorter sessions will not be able to provide adequate relief. Hence, the timer will help you to keep a tab on the duration of your massage.
- EMS Feature: Most of the TENS units come equipped with an EMS feature. This feature is better at treating chronic and acute pain than a simple TENS unit.
- Screen: Though the screen may not seem to be an important factor to consider while buying a TENS unit, its importance shouldn’t be overlooked. Look for a TENS unit that has a big screen and backlight. A small screen can be inconvenient as you have to squint your eyes to read it. Moreover, it is not the ideal option if you plan to use your TENS unit while commuting or working. Having a large screen with a backlight option is more beneficial and easy to adjust even in low light conditions.
- Battery Life: The battery lifespan and the battery type are important factors to consider. A few TENS units feature built-in rechargeable batteries, while others use two or three AA or AAA batteries. If you are buying one with built-in rechargeable batteries, it will give you the benefit of low operating costs. On the other hand, AA or AAA batteries are easy to find and relatively inexpensive.
- Accessories: The lead wire and electrode pads are the most important accessories that come with a TENS unit. The lead wire length and the gap between the pads should be factored in. A long lead wire will allow you to use the device for any part of your body. Also, the distance between the pads is important as too short a distance will result in placing the pads too close to each other, which can result in an uncomfortable experience.
- Portability: A portable TENS unit is easy to carry. Most TENS devices are small and portable, which makes it easy to use them anywhere. A few models are smaller than a mobile phone, and you can easily carry them in your pocket. Other models are slightly bigger than the mobile phone, and you will be required to carry them in your purse or backpack. Thus, the shape and size of a TENS unit are important considerations, so choose a model you will feel comfortable using.
- Warranty: When investing in a TENS unit, consider the warranty period of the device. A good warranty period reflects the manufacturer’s confidence in their products. Some devices come with a lifetime warranty, while others only offer a 30-day refund guarantee.
- Cost: The cost of a TENS unit is reflected in its replacement patches and batteries. Choose a unit that has a low operating cost and one that meets your requirements.
We hope this article has supplied you with all the relevant information that you need to know before buying a TENS unit. Make sure you consult your physician before opting for one from our list of top 7 TENS units.
