The CDC reports that 51.6 million US adults experience chronic pain (20.9% of the population).

And while studies show prescription medications work, they can have incredibly harmful side effects. The Faculty of Pain Medicine reports 50-80% of patients in clinical trials experience at least one opioid side effect. This includes:

  • Constipation
  • Itching
  • Nausea
  • Vomiting
  • And more.

If you're in search of drug-free methods of pain relief, chances are you've come across the miracle machines that are TENS units. These devices offer a safe, effective, drug-free alternative to prescription pain medications. While how these devices work is simple, selecting the right one can be complex if you’re new to this type of therapy.

Not only that but not every machine is the same. Depending on the brand, each manufacturer builds devices with different quality, features, uses, and more. Some promise TENS therapy but only deliver a massage-like sensation.

In this guide, we’ll direct you through the essentials of how to choose a TENS machine. We'll use our 45+ years experience to educate you on the different types of TENS units and key features to look for. By the end of this article, you'll be ready to choose the best device to meet your needs.

What is TENS Therapy?

TENS (transcutaneous electrical nerve stimulation) therapy is a drug-free method of pain relief. TENS therapy uses a device called a TENS unit. It sends mild electrical signals to the target area through electrodes. They achieve pain relief in two ways: endorphin release and pain gaiting.

When a TENS unit stimulates nerves, it causes the body to activate and release endorphins. The release of endorphins reduces pain and promotes feelings of happiness. This is commonly achieved with pain medication. However, TENS devices accomplish the same effect without the risk of addiction or dependence.

Have you ever started rubbing an area in pain? This is your body's way of pain gaiting. The sensation of pain works in the following ways:

  • An impact happens to cause physical pain (a bump, scratch, etc.).
  • The body’s small nerve fibers in the body part send sensory signals to the spinal cord.
  • Those signals are then sent to the brain to perceive the pain, and pain is felt.

Pain gating blocks pain signals from reaching the brain. It achieves the same sensation as rubbing or massaging an injury. TENS units perform pain gating by activating the large nerve fibers through a tingling or massaging sensation. This blocks the pain and minimizes the brain’s perception of the pain.

TENS machines are excellent for pain relief. Not only are they safe and effective, but they're universal and provide targeted pain relief. TENS devices effectively eliminate pain for a large variety of conditions, including:

Users can place the electrodes over target area, select their treatment settings, and continuously use their device whenever needed. If you’re interested in learning more about how these devices work, we recommend our Ultimate Guide to TENS Units. In it, we go further in-depth into how TENS therapy works, what it treats, and more.

Types of TENS Units

When selecting a TENS device, it's essential to understand the various types available and their specific applications. Each different type of TENS unit serves a unique purpose, catering to different therapeutic needs. The chart below provides a clear and concise overview of each device.

TENS Unit TypeDescriptionPrimary Uses/ConditionsKey AdvantagesPotential Disadvantages
TENS (Transcutaneous Electrical Nerve Stimulation)Delivers low-voltage electrical pulses to stimulate nerves, blocking pain signals and potentially releasing endorphins Chronic pain, acute pain, post-surgical painPortable, easy to use, drug-free pain relief May not be effective for all types of pain, relief may be temporary 
IFC (Interferential Current Electrical Stimulation)Delivers two medium-frequency currents that intersect in the body to stimulate deeper tissuesDeep tissue pain, muscle rehabilitation, reducing inflammationMay reach deeper tissues than standard TENS, potentially providing more effective relief for some types of deep painUnits may be more complex or require professional guidance
EMS/NMES (Electrical Muscle Stimulation/Neuromuscular Electrical Stimulation)Uses low-frequency signals to cause muscle contraction and relaxationMuscle strengthening/rehabilitation, preventing disuse atrophy, increasing circulation Can help strengthen muscles, improve range of motion, and reduce muscle spasmsPrimarily targets muscles, not directly for nerve pain relief
Russian StimulationUses a higher frequency electrical current for muscle strengthening and recoveryImproving muscle strength, size, endurance, and recoveryEffective for muscle strengthening and rehabilitation, often used by athletesNot primarily intended for pain relief in the same way as TENS

What to Look for in a TENS Machine

No device unit is the same. While they may look, feel, and act the same, differences may make or break their effectiveness. Not only that, but a suitable device will need to meet your needs depending on your pain type, level, and specific features you need. This section will cover key features to look for before buying.

Your condition (acute/chronic)

Your condition is the first thing to consider as it is going to overhaul any other factor to consider.

Cleveland Clinic defines acute pain as pain that "comes on suddenly and is caused by something specific."Chronic pain is a more severe and intense form of pain that lasts longer than six months. Unlike acute pain, chronic pain continues even after treatment.

With acute pain, almost any TENS unit will suffice. However, a decent quality device that delivers a moderate-high intensity is essential with chronic pain. Chronic pain will require more sessions, given it lasts longer. This requires a device that can provide consistent pain relief for numerous sessions.

Your target area

Most devices offer universal treatment for use on any (safe to use) area. However, there are a few which target specific areas.

Some target feet while others are for the lower back. If you only need to target a particular body part, this might be worth considering. However, these specialized devices limit where you can target.

Another aspect to consider is the target area’s size. To target large areas at once, devices need to have the ability to use more electrodes simultaneously. We’ll go further into this feature in the “channels” section.

Lifestyle (on the go, in an office, etc.)

Where will you primarily be using your device?

If you’re on the go often, then a compact unit (and even with a belt clip) might be ideal. Additionally, you’ll want one that comes with a carrying case for easy storage. If your sessions are primarily at home, these features may not matter as much.

Electrodes (stickiness, wired/wireless)

Electrodes also called TENS pads, are essential to factor in. How sticky are the electrodes, and how long do they last? Pads that aren’t sticky will struggle to adhere to the target area and be a hassle during sessions.

Types of TENS Unit Pads: Pig-tail and Snap-on

A key question frequently asked is, "are TENS pads universal?" While most devices use the same fitting, some are not. This depends on the manufacturer/brand. However, there are two standard types of TENS pads: pig-tail and snap-on.

Pig-tail style pads feature a slim end piece attachment. Their matching lead wires have a small piece of metal that slips right into the connecting element. Snap-on electrodes feature a button-style connecting portion that you press together to attach.

Sizes of TENS Unit Pads: 2" x 2", 2"x 4", and Round 3"

When it comes to size, you have a few options:

  • 2" x 2" - These are the industry standard and are what most devices come with. They're great for universal treatment but may not be ideal for larger target areas.
  • 2" x 4" - These rectangular shaped pads are ideal for larger target areas. However, they are not ideal to target joints as their larger size tends to cause them to bunch up or lift from the skin.
  • 3" Round - These are the smallest type of electrode. They're great for targeting smaller areas such as joints, fingers, and toes. Their shape and size keeps them pressed even when used over joints.

The electrode type chosen is entirely up to preference. Before deciding, consider the area you'll be primarily targeting and its size.

Wired vs. Wireless

Some TENS units feature wireless TENS pads. These options provide convenience by eliminating the risk of tangling and remaining less noticeable. This makes them great for public use. However, these can be more expensive and heavier than traditional pads.

TENS Unit Garments: A Great Alternative

Another option to consider is TENS unit garments. These specially lined gloves, knee sleeves, and socks connect to lead wires.

They require moisture to transfer the electric current.
They can be a great alternative to traditional electrodes as they don't have a stickiness to lose. However, they're not as portable as pads since they require moisture.

Do I need gel for a TENS unit?

No, most devices use pre-gelled electrodes. However, you can purchase additional gel to apply, which will extend the life of the pads.

TENS Unit Channels  Single, Dual and Quad Channels : Further details are provided below.

Channels

A TENS unit’s channels refer to the number of lead wires that can be plugged in simultaneously. More lead wires equate to more TENS pads to target a larger surface area at once. Most devices feature single, dual, or quad channels.

  • Single: Has one lead wire and can run two electrodes at once.
  • Dual: Has two lead wires and can run four electrodes at once.
  • Quad: Has four lead wires can run eight electrodes at once.

Dual channels typically suffices for most users.

Pulse duration

The TENS unit’s pulse duration is the length of the pulse it administers. Longer durations allow the device to stimulate longer. Standard devices feature an adjustable range for customizability. Pulse duration is measured in microseconds uS (1,000th of a second). 

A graphic of a pulse with text, pulse rate

Pulse rate

The unit’s pulse rate refers to the number of electrical pulses felt in one second. The frequency is measured in Hertz (Hz). Pain relief can be achieved at various frequencies, making this feature important.

For acute pain, the most effective range lies between 80 and 120 Hz. Meanwhile, a high-frequency TENS setting of 2 to 10 Hz is best for chronic pain to stimulate endorphin release. A range of 25-50 Hz is best for muscle stimulation.

Pain TypeBest Pulse Rate
Acute80-120 Hz
Chronic2-10 Hz
Muscle Stimulation25-50 Hz

Timer

Most TENS units feature a preset timer that shuts off the device after a specific period. This can add convenience or place limitations on sessions. Some feature a flexible timer or auto-shutoff, requiring you to restart the machine for extended treatments.

Intensity level

A device's intensity level delegates how powerful the treatment is. A higher intensity level from a professional grade machine delivers a more robust electrical current. Intensity levels are measured in microamperes (mA).

Most TENS units provide up to 80 mA, which is more than enough for most users. Some units deliver up to 100 mA, but most are prescription units. The more severe the pain, the stronger the intensity needed to block it.

Various TENS units with their buttons highlighted

Modes

Most TENS devices come with a set of predefined modes. These features make getting started easier by providing a set pulse duration, pulse rate, timer, and intensity. More expensive devices typically have more modes and let you select various modes for each channel. However, this may not matter if you’d prefer to customize your settings.

Portability

As mentioned earlier, your lifestyle may dictate which device is your best bet. TENS units come in all shapes and sizes and sometimes feature belt clips for hands-free use. Ask yourself, “how often will I be using my TENS unit outside of my home?” If your answer is often, then you’ll want a portable device.

Accessories

The suitable TENS unit accessories can add a lot of value to your purchase. Some kits include a:

  • Carrying case
  • Additional electrodes
  • Lead wires
  • And more.

While this can bump the price up, it can be well worth the added bang for your buck.

TENS + EMS

More advanced units feature TENS and EMS settings and capabilities. These capabilities allow them to relieve pain and strengthen muscles. A combination unit is an excellent feature if you’re looking to build and tone muscles and ease the pain. However, if pain relief is your only mission, a standard more easy-to-use device will suffice.

Various TENS brand logos

Brand

Reliable TENS brands have been making TENS devices for years; meanwhile, others are relatively new. Established brands are typically more trustworthy, make proper TENS devices, and don’t just massage your target area.

It’s also important to look into the price of their electrodes and if they’re compatible with pads that aren’t their brand. You don’t want to get stuck with a brand whose pads are expensive or not compatible with off-brand electrodes.

Reviews from customers

As with any purchase, you’ll want to look at the reviews. Look for in-depth reviews where users express their:

  • Experience with the device
  • Its features
  • And even the type of pain they’re treating. 

Looking at the types of pain treated gives you a good idea of the device’s effectiveness for specific pain types.

Reviews from experts (physical therapists, chiropractors)

TENS units are a ubiquitous device that professional physical therapists and chiropractors use. If you find a device you like, research what experts say about it. Their recommendations can provide more comfort with your decision as they are familiar with these devices. Many expert-recommended devices are readily available for purchase without a prescription.

Consider this recommendation from Therapeutic Associates Physical Therapy:

"The older style analog ones are the simplest to use and work very well. This one does not require a prescription and is the one I recommend most often. This one has more options for different areas of the body and inTENSity is a good brand and very common in physical therapy clinics."

Over the Counter vs Prescription TENS Units Comparison : Further details are provided below

Prescription or over the counter?

Does a TENS unit require a prescription?

Did you know TENS units were initially available only with a prescription? However, they’ve become more readily available over the counter over the years.

Prescription-strength devices typically feature a higher intensity setting (often up to 100 mA). They also have more treatment modes but are often more expensive. Over-the-counter units are usually more compact and not as robust. It’s best to talk to your doctor to see if a prescription is necessary.

FSA and HSA logo

Insurance Eligibility

One of the many perks of TENS machines is they're often eligible for insurance coverage. This makes them ideal for those on a tight budget. This might be worth considering when choosing a machine, as it can save money. There are a few things that may make a device eligible, including:

  • Medical necessity: The device must be prescribed as a medical necessity by a professional for a specific condition.
  • FDA approval: The device must be FDA-approved for the particular condition being treated.
  • Cost: The cost of the device must be reasonable and necessary for treatment
  • Coverage policy: Your policy must cover TENS units or other durable medical equipment.
  • Documentation: A healthcare provider must provide documentation of the medical necessity of the device and any other documentation required by the insurance company.

If getting insurance to cover your device is essential, check the TENS unit's eligibility with your insurance company before purchasing.

Frequently Asked Questions

What is a True TENS Unit?

As the popularity of TENS therapy continues to grow, it's essential to understand what a genuine TENS unit is. Many devices are labeled as true TENS but only deliver a massage-like sensation. These devices should be avoided.

A proper TENS device relieves pain through electrical impulses delivered via electrodes placed on the skin. These devices have multiple settings for intensity, frequency, and pulse duration. They feature different modes of stimulation for specific pain types.

Before purchasing any device, look at the reviews for feedback. Reviews will show you if it delivers true TENS and effective pain relief. It can also be helpful to look for medical expert reviews. If you're in doubt, consult your doctor to see if they recommend the specific device you're interested in.

How Much Does a Medical TENS Unit Cost?

As the popularity and availability of TENS units have grown, their cost has gone down. The most powerful TENS devices can be affordable in the $30 to $100 range. For prescription devices, these can be upwards of $500. The price will vary depending on features such as multiple channels, programmable settings, and wireless connectivity.

Insurance coverage eligibility is essential to know when looking for a device. Some insurance plans will cover the cost of a device that a healthcare provider prescribes as part of a treatment plan. For more information, we recommend reading our guide, "How to Get a TENS Unit Covered by Insurance."

How Often Should a TENS Unit be Replaced?

A device's lifespan varies depending on:

  • The brand/model
  • How frequently users operate it
  • And how well they maintain it

Generally, a well-maintained TENS unit can last for several years before you need to replace it.

However, the lifespan of electrodes used with a TENS unit is limited. They require replacement more frequently than the device. Electrode replacement frequency depends on a few factors, including:

  • The brand
  • How often you use them
  • How well you care for them
  • And if you wash your skin adequately before use

Electrodes can last anywhere between two to four weeks with regular use.

If you notice signs of wear and tear on your device or it's no longer effective, it might be time for a replacement. You can also check the brand's warranty to see if they will replace it for free. Many brands offer warranties that will replace the device should it malfunction within a given period.

Are All TENS Units the Same?

No, not all TENS units are the same. Each device is features distinct differences, including:

  • Different sizes
  • Different modes, intensity levels, and types of electrical stimulation provided
  • Different quality in materials, effecting the device durability, how it feels to touch, and more
  • If they're available over the counter or through a prescription
  • The type of power source: standard batteries vs rechargeable
  • And more.

Another key non-physical difference is the device's reputation. While there are many devices available, the truly exceptional machines shine through their reviews, warranty, and return policy.
