Understanding PEMF & TENS

What is PEMF?

PEMF stands for pulsed electromagnetic field. A PEMF device uses coils to create changing magnetic fields that reach the area being treated.

The setup depends on the device. You might lie on a full-body mat or place a smaller applicator near a particular area. PEMF devices also vary in their intensity, frequency, waveform and session settings, so “PEMF” does not describe one standard treatment.

What is TENS?

TENS stands for transcutaneous electrical nerve stimulation. A TENS machine sends a mild electrical current through sticky electrode pads placed on the skin, usually near the area where you feel pain.

During a session, you’ll usually feel a tingling or buzzing sensation. TENS is generally used for temporary pain relief by influencing pain signals; it does not use magnetic fields.

PEMF vs TENS: The Main Differences

How They Work

PEMF: Coils create changing magnetic fields. As these fields pulse, they can induce small electrical fields within the tissues being exposed.
TENS: Electrode pads deliver a mild electrical current through the skin to stimulate sensory nerves.

How You Use Them

PEMF: Depending on the device, you might lie on a full-body mat or place an applicator near a particular area.
TENS: You attach sticky electrode pads to the skin, usually near the area where you feel pain.

What a Session Feels Like

PEMF: Low-intensity devices may produce little to no sensation. Higher-intensity systems can be felt and can cause tingling or muscle contractions.
TENS: Usually creates a tingling or buzzing sensation.

What They’re Studied For

PEMF: PEMF has been studied for pain, inflammation, bone health and fracture healing, blood flow, sleep, and cellular energy processes such as ATP production.
TENS: TENS is mainly used for temporary pain relief, including some muscle and joint pain, sports injuries, period pain and labour pain.

Low & High Intensity PEMF: Why The Difference Matters

PEMF devices range from low-intensity mats to higher-intensity systems with focused applicators. The difference can affect both how a session feels and the kinds of effects researchers are studying.

Low-intensity mats can produce little or no noticeable sensation. Research on low-intensity PEMF covers pain and a wider range of areas, including inflammation, bone health and repair, blood flow, and cellular energy. These devices are commonly designed for home use.

Higher-intensity PEMF can be felt more clearly. Depending on the device and settings, you may notice tingling or muscle contractions. Research on higher-intensity PEMF focuses more on pain and muscle-related applications, such as muscle soreness. It can feel more active than low-intensity PEMF and, in that respect, may have more in common with TENS although PEMF uses magnetic fields, while TENS uses electrical current through skin pads.

Higher-intensity PEMF systems are available for home use, but many are designed for professional clinics, rehabilitation and sports settings. Compared with low-intensity PEMF, there is less research on broader areas such as bone repair, inflammation and cellular energy.

What Does The Research Say About Pain?

Both PEMF and TENS have been studied for pain, but research uses different devices and treatment plans for different conditions. One trial directly compared them in people with sciatic post-herpetic neuralgia. Both groups reported less pain after treatment, with no significant difference between the two therapies.

That study gives us a useful comparison, but it can’t tell us which therapy is better for every type of pain. Research has also looked at PEMF for conditions such as back pain and osteoarthritis, while TENS is mainly studied and used for pain relief.

A Closer Look at the PEMF & TENS Comparison

The trial included 56 people with sciatic post-herpetic neuralgia. Everyone received conventional physiotherapy, with one group also receiving TENS and the other PEMF. Sessions lasted 20 minutes, three times a week, for eight weeks. Both groups reported reduced pain, and the researchers found no significant difference between them.

Could TENS & PEMF Be Used Together?

TENS and PEMF have both been included in physiotherapy programmes. In one study involving people with cervical disc herniation, participants received TENS and heat alongside either PEMF or sham PEMF. This shows the therapies have been used together in a clinical study, but it doesn’t establish a standard home routine or show that combining them works better for everyone. Read the study.

People may be interested in TENS for its use in pain relief and PEMF for the wider range of areas it has been studied in. The research doesn’t yet show that the two have to be combined, or that using them together adds a specific benefit. If you want to include both in your routine, check the instructions for each device and confirm with the manufacturers whether they can be used at the same time.

Safety & Who Should Be Cautious

Both PEMF and TENS are non-invasive, but each has its own safety guidance. TENS pads should not be placed over broken or irritated skin or on areas such as the front of the neck. People with a pacemaker or another implanted electronic device should check with a healthcare professional before using TENS.

PEMF guidance depends on the specific device. If you have a pacemaker or another implanted electronic device, check the manufacturer’s instructions and speak with your healthcare professional before using PEMF. Follow the guidance supplied with either device, especially if you have a medical condition or are unsure whether it is suitable for you.

Cost & Everyday Use

TENS machines are generally a more affordable and widely available option for people interested in temporary pain relief. Their electrode pads may need replacing over time.

PEMF systems vary much more in price, from portable applicators and home mats to higher-intensity systems. Most do not use disposable electrode pads, although the overall cost depends on the type of device you choose.

Which Might Suit Your Routine?

TENS may suit you if you want a portable device with pads placed near a particular area and are comfortable with a tingling sensation. It is mainly used for pain relief, and some people use it during activities when pain is affecting their movement.

PEMF may suit you if you prefer using a mat or applicator without electrode pads. Low-intensity mats are commonly used at home and may fit a relaxed session, while higher-intensity PEMF is more targeted and can feel more noticeable.

Think about the type of session you would actually use, the area you want to focus on and the device’s settings. Neither approach is automatically the better choice; they offer different experiences and have been studied in different ways.

PEMF vs TENS: The Key Takeaway

TENS delivers electrical current through pads on the skin and is mainly used for temporary, targeted pain relief. PEMF has also been studied for pain, but research extends to areas such as bone health, inflammation, circulation and cellular energy.

For a pain-focused routine, we would favour PEMF because it offers a broader potential use case. TENS can be a more affordable starting point, while PEMF usually costs more upfront; TENS pads also need replacing over time.

FAQs

Is PEMF better than TENS?

There isn’t one answer for every person or type of pain. In one small study of people with sciatic post-herpetic neuralgia, both groups reported improvement, with no significant difference between the PEMF and TENS groups. That result applies to the specific condition and treatment programme studied. In our view, PEMF has a broader potential use case, with research exploring areas such as bone health, inflammation, circulation and cellular energy alongside pain relief.

Can you use PEMF and TENS together?

They have been used together in clinical treatment programmes, but that doesn’t establish a standard routine for using home devices at the same time. Check the instructions for both devices and ask the manufacturers if you’re unsure whether your specific systems can be used together.

Does PEMF feel like TENS?

TENS usually creates a tingling or buzzing sensation from the electrical current delivered through its pads. Low-intensity PEMF may produce little sensation, while higher-intensity PEMF can feel stronger and may cause tingling or muscle contractions, depending on the system and settings.

Do PEMF and TENS use the same technology?

No. TENS delivers electrical current through pads on the skin. PEMF uses coils to create pulsed magnetic fields. The technologies are different, even though both have been studied for pain.

Are all PEMF devices the same?

No. PEMF devices vary in their intensity, frequency, waveform, applicator and session settings. Research on one device or protocol may not apply to every PEMF system.

What if I’m still unsure which one to choose?

Think about the kind of session you prefer, whether you want to use electrode pads, and what you want the device to fit into your routine. If you have a question about a specific device or using PEMF and TENS together, send it to us below.
