PEMF Mats: What the Evidence Says

Last verified November 2, 2026. Every FDA record, grade and price on this page links to what we checked. Where we couldn't confirm something, we say so.

We have not tested any PEMF device, and we don't pick a PEMF mat for any health use.

The short answer

PEMF (pulsed electromagnetic field) therapy has two very different lives. In medicine, prescription PEMF bone stimulators are FDA-approved for fractures that won't heal¹, and a few small wearables are cleared for musculoskeletal pain². Even there, the evidence is mixed³. Consumer PEMF mats are another product. We found no FDA clearance for the popular mats, and no randomized trial of a consumer whole-body mat. For knee osteoarthritis, the most-studied use, the two most recent meta-analyses found no clear benefit for pain⁴⁵. If you want a mat for warmth and relaxation, that's fine. Don't buy one to treat a condition.

Status snapshot: what FDA has reviewed

"PEMF" covers everything from prescription bone stimulators to $500 mats. This is what FDA records show for each type.

Device type	FDA status	Example we looked up	What it tells you
Bone growth stimulator (worn over a fracture)	Premarket approval (PMA), Class III, product code LOF, prescription only	Orthofix Physio-Stim, PMA P85000716	FDA's strictest review. Used for fractures that haven't healed, under a surgeon's care.
Small wearable for musculoskeletal pain	510(k) under the shortwave diathermy regulation (21 CFR 890.5290), over the counter	ActiPatch: K152432 (knee osteoarthritis and heel pain), K192234 (musculoskeletal pain)72	Cleared as an add-on pain treatment. Based on small sponsor trials.
Whole-body consumer mats	No clearance found for the mats in our price table	HigherDOSE, HealthyLine, Bon Charge, Hooga, Grooni8	Sold as wellness products. Wareable calls them "wellness devices, not medical treatments"8.

Approved, cleared, registered. "Approved" (PMA) and "cleared" (510(k)) both mean FDA reviewed a specific device for a named use. "FDA-registered" means only that a company or factory is listed with FDA. A mat brand that is "registered" has had no review of its claims. Ask for a K or P number and look it up.

Other PEMF and pulsed shortwave devices are cleared under the same 890.5290 regulation as ActiPatch, mostly for clinic use. ActiPatch's own predicates include earlier pulsed devices⁷. We didn't review those records for this page, because none of them is a consumer mat.

Evidence map: graded by use

Grades: A consistent randomized trials or meta-analyses. B supported by randomized trials that are small or varied. C few, mixed or mostly negative trials. D lab, animal or anecdotal only, or no trials of the device type. X a safety signal.

Use	Grade	Best evidence	What the trials used
Knee osteoarthritis: pain	C	A 2013 Cochrane review (9 trials, 636 people) found 15 points more pain relief than placebo on a 0 to 100 scale9. Two newer meta-analyses disagree. One (8 placebo-controlled trials, 421 people) found no significant benefit for pain or stiffness4. A 2026 review (9 trials, 457 people) found no significant overall benefit for pain or function, and a high risk of bias in most trials5.	Clinic or prescribed devices applied to the knee, with varied settings
Knee osteoarthritis: function and strength	C	The 2019 meta-analysis found better WOMAC physical function4; the 2026 review found time-specific gains that didn't reliably reach clinically meaningful levels5. A 2026 placebo-controlled trial of 60 people found stronger knee extension at 6 months but not at 12, and no change in function, cartilage or joint space10.	1 mT, 50 Hz device, 30 minutes 3 times a week for 8 weeks10
Fractures that won't heal (non-union)	C	Cochrane review, 4 trials, 125 adults: healing rates were not significantly better (risk ratio 1.96, 95% CI 0.86 to 4.48). The authors call the evidence inconclusive3. FDA has approved prescription stimulators for this use1.	Prescription bone stimulators worn over the fracture
Heel pain and knee pain (small wearable)	C	Two sponsor trials in ActiPatch's 510(k) file. Knee osteoarthritis: 66 people, 36% vs 9% had at least a 30% drop in pain. Heel pain: 70 people, 7 days, 40% vs 7% less morning pain7. Both are summarized in the company's 510(k) file. The knee trial appears to have been published as a double-blind trial of a wearable PEMF device13; we didn't find a peer-reviewed version of the heel trial.	ActiPatch worn over the painful area
Recovery, sleep, energy, "inflammation" (mats)	D	We found no randomized trial of a consumer whole-body PEMF mat for these uses. Mat marketing borrows from trials of different devices at different settings.	No trials of mats

The pattern: the uses FDA has reviewed involve devices placed directly over one joint or fracture, under specific settings. Even those have mixed results. A mat under your whole body is a different device, and it hasn't been tested for the things it is sold for.

If you still want to buy something

We pick only where a device meets all four criteria, applied to every brand whether or not it pays us: (1) the use has at least C-grade evidence from randomized trials, (2) the device is FDA-cleared for that use and we could look up its number, (3) its price and return terms are published, (4) commission plays no part.

Knee or heel pain: a cleared wearable, not a mat

ActiPatch is the only over-the-counter PEMF-type device we found with a clearance for a named pain use: knee osteoarthritis and plantar fasciitis (K152432), later broadened to musculoskeletal pain (K192234)⁷². The evidence is grade C. We couldn't open ActiPatch's store to check its price or return terms, so it doesn't fully meet criterion 3. If you try it, buy where you can return it. For knee pain, a TENS unit is a cheaper alternative with more trials behind it¹¹; see our TENS unit picks.

Mats: no pick

No mat meets criterion 2, and none has trials for the uses it is marketed for. If you want one anyway, treat it as a heating pad you like lying on, and compare on price, warmth, size and return policy.

Mat prices and FDA status

Prices checked November 2, 2026 on Wareable's and Outliyr's roundups, because the brands' own stores didn't load for us. Brand prices change often, so check before you buy. We found no FDA clearance number for any of these mats.

Mat	Price	Source	FDA clearance found
Hooga Infrared PEMF Mat	$699	Wareable8	None
HigherDOSE Infrared PEMF Go Mat	$699	Outliyr12	None
HealthyLine TAJ	From $679	Outliyr12	None
Therasage TheraPro	From $546	Outliyr12	None
Grooni PEMF Infrared Mat Pro	$899.99	Wareable8	None
Bon Charge Infrared PEMF Mat Max	$974.25 (Wareable); from $349 by size (Outliyr)	Wareable, Outliyr812	None

HealthyLine Platinum Mat	$1,999 (Wareable); $999 to $4,999 by size (Outliyr)	Wareable, Outliyr812	None

No independent lab has published field-strength measurements for these mats that we could find, so there is no measured column. Most of them combine PEMF with infrared heat, which is the part you will actually feel.

How to read PEMF claims

• Ask for a K or P number. Look it up in FDA's 510(k) or PMA database and check that the device and use match. "FDA-registered" is not a review.
• Check which device the cited study used. Knee and fracture trials used devices placed on one body part at set field strengths and frequencies¹⁰³. Those results don't transfer to a full-body mat.
• Check the size of the effect. Even positive knee results were small or short-lived⁵¹⁰.
• Prefer a long return window. Without good evidence, your own trial is the test.

Safety

The trials we cite enrolled adults with knee osteoarthritis or fractures. They tell you nothing about pregnancy, children, or people with implanted electronic devices. If you have a pacemaker, defibrillator, pump or other implant, ask your doctor before using any device that produces a magnetic field. If the mat also heats, follow its heat-setting and time limits, especially if you have reduced feeling in your skin. Don't delay treatment for a fracture or joint problem to try a mat.

Myths

• "PEMF is FDA-approved." Prescription bone stimulators are¹. That approval doesn't extend to any consumer mat.
• "Studies prove PEMF reduces arthritis pain." An older Cochrane review was positive⁹, but the two most recent meta-analyses found no clear benefit for pain⁴⁵.
• "PEMF heals fractures, so a mat speeds recovery." Even for non-union fractures, the Cochrane review found the evidence inconclusive³. Mats haven't been tested for workout recovery.
• "Registered with FDA means safe and effective." Registration is a listing, not a review.

FAQ

Do PEMF mats work?

We found no randomized trial of a consumer whole-body mat for recovery, sleep, energy or pain. The evidence that exists is for other PEMF devices, and it is mixed.

Are PEMF mats FDA-approved?

We found no FDA clearance for the popular mats. FDA-approved PEMF devices are prescription bone stimulators¹; a few small wearables are cleared for pain⁷².

Does PEMF help knee arthritis?

Maybe a little, but the evidence is inconsistent. A 2013 Cochrane review was positive⁹; a 2019 meta-analysis found no pain benefit⁴; a 2026 review found no significant overall benefit⁵.

Does PEMF help broken bones heal?

Prescription stimulators are approved for fractures that won't heal¹, but a 2022 Cochrane review found the evidence inconclusive³. That decision belongs with your surgeon.

How much does a PEMF mat cost?

From about $350 to $2,000 for the mats we priced, and up to $4,999 for the largest sizes⁸¹².

Is PEMF safe?

Few harms were reported in the knee and fracture trials, mainly minor skin irritation with fracture stimulators³. Ask your doctor first if you have an implanted electronic device or are pregnant.
