Pain is complex, but it’s something we can all identify with. Not only are there different types, causes and severity levels, you can also experience pain in different areas of your body.
The treatment options are as varied as the causes, from acupuncture, herbal therapies and over-the-counter medications to injections, chiropractic treatments and in extreme cases even surgery.
Another pain management alternative currently gaining popularity is Transcutaneous Electrical Nerve Stimulation Therapy also known as TENS.
A TENS unit can be used to treat joint, neck and back pain, post-operative pain, period pain, migraines and even labour pain.
Furthermore, if you suffer from pain due to multiple sclerosis, endometriosis, arthritis, fibromyalgia or sport-related injuries, it might also prove helpful.
In this article, we’ll delve into the uses of a TENS unit, the benefits of owning one, and the important features to look for when purchasing this device.
Today we’ll be looking at the following best TENS units:
What is a TENS Unit?
This kind of treatment is achieved via a TENS unit.
It is a small, battery operated, electronic machine with adjustable settings. Attached to the device are electrodes which look like tiny cords with small adhesive pads at the end of each one.
The pads are stuck onto the body above the aching areas. Once the pads are stuck on, the TENS unit will send small electrical currents to stimulate the nerve endings to the areas of the body under the pads.
Purposely electrocuting oneself doesn’t sound appealing, nor does it sound like it would relieve pain, however, the jolts of electricity are small enough that it is safe to use.
Typically units are battery powered or charged via USB, and are not plugged straight into a mains supply.
The device has different channels, frequency modes and intensity levels which you can set according to your pain level.
Given that TENS units are small and portable, many people use them while on the move or when they are working. Some units can be attached to clothing, clipped onto a belt or held in a trouser pocket.
How Exactly Does a TENS Unit Work?
The TENS unit works by attaching the adhesive pads to the area on your body surrounding the painful area. Once attached, you then turn on the unit and set the appropriate level of intensity that you require.
The machine transmits electrical currents which travel through the electrodes and into your skin and the tissues underneath. These electrical currents or impulses then inundate the nervous system ultimately decreasing its ability to send pain signals to your brain.
A study published by the US National Library of Medicine shows that TENS can indeed prove effective in lowering or blocking pain signals travelling to the brain.
Additionally, depending on the frequency of the unit, the electrodes can cause your body to release endorphins -which act as natural pain relievers.
This pain management treatment is safe and non-invasive and there are no major side effects; some devices offer pain relief for up to 24 hours.
TENS vs EMS Treatment
If you’ve already heard of TENS, you may have come across the similar term EMS (electrical muscle stimulation). The two are often confused.
Both use electrical pulses to target areas of the body, but the difference between the two is in their names. Whilst the TENS will target nerves, EMS targets muscles.
The Benefits of Using a TENS Unit
If you’ve never used a TENS unit before, you might be wondering if it’s really worth investing in.
These portable machines have their benefits and are being used in countries around the world to treat varied pain-related conditions.
Some of the benefits include:
Aids in Muscle Recovery and Relaxation – Some units are designed to help athletes or persons who engage in daily exercise regimens and suffer from muscle aches and pain. A 2007 research, published in the Journal of Clinical Science concluded that TENS was effective in treating delayed onset muscle soreness (DOMS).
Produces Endorphins – These are described as the natural painkillers in your body. When you attach a TENS unit to your skin, the electrical impulses can signal these hormones in the brain for your body to produce endorphins to further aid in pain relief.
Minimal Side Effects – Unlike many other pain management treatments which often have several side effects (some worse than the pain itself) TENS does not. There have been a few instances where users had allergic reactions to the pads that attach to the skin, so if you have allergies you may want to pay special attention to the type of material used in these pads.
Portable and User-Friendly – The TENS units are smaller than many cell phones and can easily fit in your pocket or small bag. Due to the size and lightweight factor you can also travel with the device from home to work or even take it with you on vacation.
Offers Longevity – Unlike pills or injections that can wear off over time the TENS unit offers a long-term solution for pain management. These devices are meant to last for several years with proper care.
Pain Relief – A TENS unit is best used only for short-term pain relief and is not intended to deal with chronic pain. It may be useful for general, neck, knee and back pain.
It is also commonly used for helping pain associated with arthritis and period pains. People who are recovering from injuries sustained during sports may also find a TENS unit beneficial.
What to Look for When Choosing a TENS Unit
If you’ve never used or purchased a TENS unit before, the process might seem a bit daunting – especially with so many options now available.
Well, to make your life easier we’ve shared some of the best features to look for when purchasing your TENS unit.
Most TENS unit are battery powered. Some require one 9-volt battery and other models may require three AAA batteries. It all depends.
Given the day and age we live in, some of the more ‘tech-savvy’ buyers may prefer a TENS unit that is chargeable via USB. These type of TENS unit are becoming more available, however, the battery type still tend to dominate.
If you don’t want the hassle of having to spend money on buying batteries then the USB type of TENS unit will be a better choice. However, some people may prefer the simplicity of using batteries.
Number of Channels
A TENS unit which is ‘dual channel’ means that it is able to send two different intensities across its electrodes.
This is beneficial if you wish to work on two different parts of the body with two different intensities, or if you are feeling in a generous mood, a dual channel TENS unit can be shared them with someone else.
If you want to keep your sessions with your TENS unit simple you may not need a dual channel unit.
Different TENS units will come with a different number, and size of pads. This may be an important factor depending on the part of the body you plan to use them the most on.
A proper TENS unit is one that gives you the option of different therapy modes. This will allow you to set the unit to particular settings based on the type of pain you’re experiencing. The most common modes on a unit includes, burst, constant and modulation.
Some of the TENS units also come with different modes which mimic different types of massages.
For some people, this may not be necessary and may even make the whole process overly complexed. We have outlined one TENS unit with 24 of these modes. Does this seem like overkill to you?
You will need to decide whether these modes are of benefit to you or not. If you don’t need them then you can buy a simpler TENS unit and save some money in the process.
This is important because different types of pains and certain areas of the body will require a different intensity level to alleviate the pain. Most TENS units have 20 or more intensity level options so make sure to read the description before purchase.
The number of intensity levels is likely to be the most important factor. Ideally, you want a TENS unit with many levels so you can find the right intensity of electrical current you need to relieve your pain.
You’ll want to invest in a unit that is high quality and durable; especially since they don’t come cheap.
The material used to make the product is not always displayed in the description, but a money-back guarantee or some kind of warranty is an indicator of a good product.
Prices can range from about 30 bucks on the lower end, to over 300 dollars. Keep in mind that more expensive doesn’t necessarily mean that the product is a good buy, but many of the good ones are indeed on the higher end of the budget.
Compare the low and high-end options and look at the features that account for the price of the item, and then choose something that offers the best features and work within your budget.
