Join us as we provide expert insights and first-hand experiences to help you make an informed decision about this groundbreaking medical device.
Our team of health experts and pain management specialists has extensively researched and tested the Zynex NexWave TENS unit. Additionally, we have consulted patients who have used the device to gain a deeper understanding of its performance and efficacy.
Let’s start the review with one of our resident patient’s personal experience.
“When I had an accident that resulted in the paralysis of one side of my body, I thought it was the end of my world. I experienced so much pain that often made me scream and cry at the same time. That’s why my physical therapist sought solutions other than drugs to help relieve my pain and build up my atrophied muscle. That’s when I discover the Zynex NexWave” – David
Injuries, muscle atrophy and other pain-inducing conditions often make one depend on opioids, muscle relaxants, over the counter drugs (OTC) etc. These medications often have side effects and other long-term issues. Therefore, medical devices that incorporate technologies such as neuromuscular electrical stimulation (NMES), interferential current (IFC) or transcutaneous electrical nerve stimulation (TENS). The Zynex NexWave is a good example and a lifesaver.
What’s more, they are often portable and can be used at home, work etc.
What is IFC, NMES and TENS? How do they apply in my condition? What is Zynex NexWave? How does it work? Those popular questions and more are what we will be answering in this review article.
Let’s begin by exploring the three technologies integrated into the Zynex NexWave TENS unit…
What is Interferential Current (IFC) or Interferential Therapy?
Interferential current or therapy is the use of electric current to stimulate nerves for the purpose of pain relief and other benefits.
It is a type of therapy that takes advantage of low frequency instead of superficial nerve stimulation, and it is known for its deeper penetration. Hence, consequently, its therapeutic effects.
The use of low frequency to stimulate nerves is often associated with discomfort and pain due to the difference in the skin and the electrical stimulation. What this means is that:
Low frequency = greater impedance (greater resistance)
Higher frequency = lower impedance (lower resistance)
However, unlike other types of treatment modalities that make use of this principle (Low frequency), interferential current machines deliver higher frequencies that interfere to give a beat frequency (resultant low frequency). These higher frequencies can penetrate the skin and cause fewer discomfort or pain.
The principle behind this IFC machines is that the electrodes delivering these high frequencies are crossed to give a resultant medium or low frequency.
For example:
When two electrodes of 4100Hz are crossed with other electrodes of 4000Hz, the resultant or beat frequency that will finally stimulate the nerve is 100Hz.
IFC works like a TENS unit; it’s just that it yields better results and a more intense therapeutic effect.
The best it can explain by comparing it with TENS.
Tip: NeuroTrac TENS Device can relieve pains too.
What is Transcutaneous Electric Nerve Stimulation (TENS)?
Transcutaneous Electric Nerve Stimulation or TENS is the process of administering voltages or electrical stimulation to superficial nerves for the purpose of pain relief etc. It can be used both in the hospital and at home.
They are used for relieving pain from injuries, period pain, lower back pain, arthritis, fibromyalgia etc.
There is not much difference between IFC and TENS units, except the fact that IFC currents interfere to give a resultant frequency or electric current. The overall results and use are the same except that IFC effects are more intense.
Compared with IFC and TENS, the NMES is a bit more different.
Tip: XFT 320A TENS Machine comes with an Acupuncture Pen.
What is Neuromuscular Electrical Stimulation (NMES)?
NMES denotes neuromuscular electrical stimulation and can also be called electrical muscle stimulation (EMS).
It is the use of electrical current to stimulate muscle contractions. It mimics the stimulating action of the central nervous system.
EMS is particularly useful for people with partial or full paralysis, used in muscle building or strength training for trainers and for testing muscular function etc.
Notice the similarities between IFC, TENS and NMES? All of them utilize electrical stimuli or impulses to deliver their impact within the body.
How Do They Work?
IFC, TENS and NMES (EMS) technologies and home-based innovations usually come in a portable form. They deliver their impulses through electrodes. These electrical impulses are generated by the battery.
The electrodes are adhesive pads with wire attached at the ends.
Now, let’s compare the IFC, TENS, and NMES Technologies.
| Technology | Application | Therapeutic Effect | Intensity |
|---|---|---|---|
| IFC | Deeper pain relief | More intense therapeutic effect | Higher |
| TENS | General pain relief | Mild therapeutic effect | Moderate |
| NMES | Muscle stimulation | Muscle building and function | Moderate to High |
Tip: Are you with migraine? Then Cefaly Anti-migraine Device might be a better option.
What are the Side Effects of IFC, TENS, NMES?
They are generally safe for most people, but here are some possible side effects.
- You may experience a tingling feeling or pin-pricks in the area that it is being utilized
- Some people can be allergic to the adhesive pads.
- This often presents as itchiness or redness in the area that the electrodes were attached. However, you can choose electrodes with hypoallergenic adhesive pads.
- As a pregnant woman, you may experience possible complications. Therefore, pregnant women are advised not to use them without the advise of their doctor.
- People with pacemakers and heart problems are to contact their doctors before using, since it may lead to complications.
Now let’s turn into the device we review in this article, which is based on the above 3 technologies.

Zynex Rep calls an gives you a rental price of $25 per month if your insurance co won’t cover the use of this unit. Sounds ok right? The rep does not tell you that most likely insurance will not cover the unit and once Zynex adds on charges for wires, sensors and batteries (which you do not use all of these & return the still sealed unused ones) for a 2 month charge they 1st try collecting from insurance is now $396 instead of the $50 you were told it could be. insurance CO denies the claim so now Zynex sends you a bill for $250. Lots of “Bait & Switch” goes on with this deal. Plus you can either purchase like units online or even Walmart for way less dollars an then you own it. Yes, Zynex sells these same units online, an any needed supplies for less than rental costs. So check out what’s needed an what’s out there before doing a rental from Zynex. Check with your insurance CO to see if they will even cover a rental.
