How were these TENS units selected? 

Back pain is one of the most common referrals in physical therapy, affecting millions of individuals worldwide. 

In the majority of cases, recovery from back pain can take about 8-12 weeks, provided adherence to a comprehensive treatment approach. This approach often includes therapeutic exercises like core and hip strengthening, stretches for spinal mobility, activity and ergonomic modifications, behavioral adjustments, and…pain management strategies. 

This is where a TENS unit comes in. 

Electrical stimulation (e-stim) has various applications, including reducing pain and inflammation, promoting the growth of bone and tendon, facilitating wound healing, aiding in muscle reeducation, and strengthening muscles. TENS is a specific type of electrotherapy, which is used for pain management. 

I will be blunt: a TENS unit is not a miracle cure, and used alone, it is likely not going to cure your back pain. 

However, when used in conjunction with therapeutic exercises and lifestyle modifications, it can provide effective pain management and promote recovery, allowing individuals to adhere to their exercise regimen and maintain their daily activities, which are essential for chronic pain relief and long-term improvement in back pain.

Based on my clinical knowledge, experience, and user feedback, these five units stand out for their ability to deliver high enough intensity for effectual treatment while maintaining user-friendly features. I also took into account affordability and convenience in the selection process. 

What is the best TENS unit for back pain?

The best unit for you really does depend on your needs and priorities.

Below is a summary table of the specifications:

Note that for some of the units, the max intensity is not numerically specified. This is because the perception of intensity can vary between units manufactured by different companies. For instance, 60 mA of intensity on one unit may feel different compared to 60 mA on another unit from a different manufacturer. Consequently, some companies opt not to provide specific numerical values for intensity.

4. TENS 7000 2nd Edition Digital TENS unit by TENS pros

Overview

The TENS 7000 2nd edition digital TENS unit distinguishes itself from other units on this list because it has less pre-set programs, which allows you greater control over the settings. 

For instance, the user starts by selecting one of the five modes—let’s say you pick the normal mode. Then, you get to choose a pulse width ranging from 50 to 300 microseconds (I recommend 100-250 microseconds or higher for TENS). Next, pick your pulse rate from 2 to 150 hz—whether you go low or high, it’s up to you. Finally, set your therapy duration from 0 to 60 minutes.

Some of the modes in the TENS 7000 2nd Edition do come with preselected pulse width or pulse rate. 

Additionally, it includes modes where settings like pulse width and intensity automatically shift during the treatment session. The purpose behind this feature is to prevent users from becoming too accustomed to the sensation of TENS by introducing variability in the settings. 

Still, it’s worth noting that becoming accustomed to the TENS sensation isn’t necessarily a drawback, as the activation of nerve fibers remains effective. Ultimately, it boils down to user preference – whether you prefer the consistency of specific settings or the experience provided by automatic adjustments during your TENS session.

What is TENS? 

TENS, or transcutaneous electrical nerve stimulation, is a commonly used form of electrotherapy aimed at managing pain. 

Using adhesive pads placed on the skin, a TENS machine delivers electrical stimulation to regulate nerve signals. Operating through the peripheral nervous system, it engages nerve endings, particularly activating mechanical receptors. These receptors transmit signals to the brain, resulting in a decrease in input from pain receptors and a subsequent reduction in the perception of pain. There are also other proposed mechanisms behind how TENS works. It also helps improve blood circulation to the target area and promotes healing.

TENS is employed in various pain management scenarios, addressing issues such as muscle tension, nerve pain, chronic pain, or post-surgery discomfort. It is often integrated into clinical settings and can be incorporated into therapeutic exercises to aid in pain management and encourage engagement in activities crucial for long-term pain reduction.

What setting should I use on my TENS unit for back pain?

You may have questions about how to use a TENS unit for lower back pain, such as setting and electrode pad placements.

Many TENS units come with preset settings, where you’ll likely need to select a program and then adjust the intensity as needed. While there aren’t many confirmatory studies providing strict guidelines for maximizing the benefits of TENS therapy for individuals,one of the key factors to consider when using TENS is the intensity level.

You’ll want to adjust the intensity to a level where you feel a strong sensory perception, such as a strong buzzing or tingling sensation, without discomfort. If you experience muscle contraction, it’s advisable to lower the intensity to ensure you achieve optimal pain relief.

As for other settings, it is recommended to keep the pulse duration, or pulse width, between 100 to 250 microseconds or higher. Further, frequency or pulse rate is more dependent on the user. Some people prefer the sensation that high frequency TENS offers compared to low frequency TENS, but you can try it out for yourself. 

As for duration – TENS units are usually utilized for durations ranging from 15 to 30 minutes per session. The flexibility is noteworthy as you can incorporate it into your schedule multiple times a day. To highlight, there isn’t a rigid restriction on TENS usage, as it’s not linked to addiction.

Is TENS safe?

Yes, TENS is safe so long as you follow the provided instructions and suggestions for when TENS should not be used. Overall, TENS is non-addictive and side effects are rare. In some cases, people have had an allergic reaction to the gel electrode pads, which resolves after disuse. 

Since TENS devices are classified as medical devices, manufacturers must adhere to specific FDA guidelines for approval, ensuring regulated distribution.

That said, you should not use a TENS in following regions and cases:

• Abdomen of pregnant women
• Over regions of known or suspected malignant
• Over recently radiated tissue
• Over damaged or broken skin (such as open sores)
• If you have pacemaker or other electronic device implants (such as implanted defibrillator)
• If you are connected to high frequency surgical equipment
• Near or over eyes
• Front of neck region
• Over chest wall

Please be aware that this list is not comprehensive, and it is strongly recommended that users refer to the manual that accompanies their devices for detailed guidelines to ensure the safe and effective use of electrical stimulation for therapeutic purposes.

Also consider talking to a healthcare professional for further guidance if you are unsure. 

Will TENS cure my back pain?

TENS alone is not the solution to your back pain. It can be part of a pain management plan within a more comprehensive treatment approach which can include strengthening exercises, stretches for mobility and range of motion, endurance based exercises, functional activity reeducation, and lifestyle modification. 

Back pain can be caused by multiple factors, and you have been dealing with persistent back pain, I highly recommend seeking help from a medical professional. They can offer you further guidance or referral to the right professional so you can get the care suitable for your needs. 

In summary, while TENS can contribute to effective pain relief, it’s not the sole solution. Rather, consider it a facilitator – a TENS machine empowers you to manage pain, enabling you to partake in daily activities and prescribed exercises. Consistent participation in these exercises forms the cornerstone for achieving lasting, long-term pain relief. 

What is the difference between TENS and EMS?

TENS and EMS are often used interchangeably, which can lead to some confusion.

EMS encompasses various therapies utilizing electrical stimulation to induce muscle contraction, aiding in strength gain and addressing a range of physiological needs. While TENS can be considered a form of electrical muscle stimulation within exercise circles, this distinction may be unnecessary for our discussion. Beyond clinical contexts, EMS serves as an umbrella term for techniques that stimulate muscle contraction, promoting not only strength but also tendon growth, improved blood circulation, muscle reeducation, wound healing, and pain and inflammation reduction. Electrode pads are strategically placed over motor points within the target muscle, where nerves converge to initiate muscle contractions. In certain healthcare fields like physical therapy, EMS further divides into specific categories, notably NMES (Neuromuscular Electrical Stimulation) and FES (Functional Electrical Stimulation), each with distinct applications and benefits.

If you’re receiving treatment from a physical therapist for your back pain, there’s a possibility that NMES could be integrated into your routine, contingent on your specific presentation and the physical exams. 

NMES primarily aims at promoting strength gain, aiding in muscle recovery, and preventing muscle atrophy. To optimize its effectiveness, individuals undergoing NMES therapy are encouraged to tolerate the highest tolerable amplitude during stimulation. This approach makes intuitive sense: stronger muscle contractions typically yield greater strength benefits. 

On the other hand, there are three different types of TENS: sensory level TENS, motor level TENS, and noxious TENS. The primary type of TENS and most applicable to this article is sensory level TENS. 

Sensory TENS involves stimulation that doesn’t trigger muscle contractions but rather produces a gentle tingling or buzzing sensation. This approach can serve as an effective pain management strategy for individuals grappling with injuries or chronic pain, seamlessly integrating into daily routines, even during activities.

The intensity of TENS therapy varies from person to person, targeting a moderate tingling or buzzing sensation during application.

It’s important to note that within a few minutes of using TENS, you may experience a decrease in both the perceived intensity of the sensation and your pain levels. This adjustment is entirely normal and signifies your body’s adaptation to the stimulation; As I had mentioned earlier, this doesn’t indicate a decrease in effectiveness as pain management is still being addressed.

Bottomline

All of these TENS units offer solid options when selecting one as part of a pain management plan. Each unit comes with its own unique features and functionalities, catering to different preferences and needs. Remember to follow safety guidelines and consult the accompanying manuals for comprehensive usage instructions, ensuring a secure and effective incorporation of electrical stimulation into your therapeutic routine.
