A PEMF blanket for horses is a rug-style pad with built-in coils that produce a low-intensity pulsed magnetic field over the horse's back and hindquarters. Owners use it as part of a yard routine, usually before or after work, running one of the controller's preset programmes. It isn't a treatment for lameness or injury, and research in horses is still small-scale, so treat it as a wellbeing tool and keep your vet in the loop.
This guide explains how equine PEMF blankets work, what to check before you buy one, how to introduce it on the yard, and what the latest research does and doesn't tell us. If you're weighing up PEMF against light therapy, our red light therapy for horses guide covers the other option.
What is a PEMF blanket for horses?
PEMF stands for pulsed electromagnetic field. A small controller sends short pulses of current through copper coils sewn into the blanket, and each pulse creates a brief magnetic field that passes through the coat, skin and underlying tissue. Unlike light therapy, it doesn't need bare skin or direct contact, so a winter coat, a clip or light mud makes little practical difference.
The field is weak. Our OMI™ PEMF Blanket for Horses, for example, runs three programmes between 1 and 99Hz at up to 220µT (roughly 2.2 gauss), using eight coils. Most horses don't appear to react to the field itself, which is one reason many accept it quickly.
PEMF blankets for horses vs leg and neck wraps
A blanket covers the largest area in one go: the back, loins and hindquarters, where many ridden horses carry tension. Wraps target smaller areas.
- Blanket: back, loins and quarters. The usual first purchase.
- Neck and shoulder wraps: for horses whose routine focuses on the front end.
- Leg wraps: front or rear, fastened like a stable boot.
Most systems share one controller across applicators, so you can start with a blanket and add wraps later. The OMI PEMF Horse Complete Pack bundles a blanket, neck, shoulder and two leg wraps, and our equine range shows everything we carry.
What does the research say about PEMF for horses?
Honestly: not much yet, and what exists is small. Two recent pieces of work are worth knowing about.
In August 2026, Hungarian researchers published a pilot study in the Journal of Veterinary Medical Science in which five sport horses had whole-body PEMF delivered by a full-body blanket on five consecutive days. They measured 72 blood values before and after. Several blood values shifted, but cortisol (a stress hormone) and thyroxine didn't change significantly, and the authors reported no detectable adverse effects over the five days. With five horses and no long-term follow-up, it's a safety signal worth having rather than evidence of benefit.
Separately, a Colorado State University team presented a small study at the 2025 Equine Science Society Symposium, reported by The Horse, looking at six mares with joint changes after a single 30-minute PEMF session. A vet's subjective scores changed briefly at one hour, but objective motion sensors showed no improvement, and the researchers called for more standardised treatment protocols. In short, PEMF in horses is an area of active interest, but there isn't yet good evidence that it treats any condition. Anyone who tells you otherwise is getting ahead of the science.
How to use a PEMF horse blanket on the yard
OMI™ PEMF Blanket for Horses
Introducing it
- Let your horse see and sniff the blanket with the controller off.
- Put it on like a light rug and do it up, then take it off again after a couple of minutes.
- Run a first session at the gentlest programme, somewhere your horse is relaxed, ideally with a haynet.
- Stay with your horse for every session. Don't leave equipment with cables on an unattended horse.
How long is a session, and how often?
Follow the programme times supplied with your system, and if a blanket arrives without clear session guidance, ask the supplier which programme to use and for how long before you start. Owners commonly use a blanket a few times a week, fitted around existing routine: after grooming before work, once the horse has cooled down after work, or on rest days. As with any yard routine, the one that actually happens consistently is better than an ideal one you can't keep up.
Can you use it under a rug or while travelling?
Because the field passes through fabric, a PEMF blanket can usually sit under a light sheet. Don't use it under heavy rugs that could make the controller or cables overheat, and follow the manufacturer's guidance. Portable systems can be used at shows or in the lorry, but never while the horse is being ridden, lunged or travelling on the road.
When not to use a PEMF blanket
Manufacturers list contraindications for good reason. The OMI system, for example, should not be used on mares in foal, horses with electronic implants, horses with a fever or infection, or horses receiving cancer treatment, and it shouldn't sit over the eyes. Beyond that:
- Any new lameness, heat, swelling or a wound needs a vet first. PEMF is not a way to find out whether something is serious.
- Suspected laminitis or colic is an emergency – call the vet, don't reach for equipment.
- Stop if your horse becomes unsettled or objects to an area it previously accepted.
- If you compete, check your governing body's current rules on therapy devices before and during events.
Frequently asked questions
Do PEMF blankets for horses work?
There's limited published research in horses, mostly small pilot studies, and no good evidence yet that they treat any condition. Many owners use them as part of a routine. Talk to your vet about whether it suits your horse.
Is PEMF safe for horses?
At the low intensities used in equine blankets, a 2026 pilot study found no detectable adverse effects over five days. Follow the manufacturer's contraindications and get veterinary advice for any horse with a medical condition.
Can a horse feel a PEMF blanket?
Most horses show no obvious reaction to the field itself. They react to the blanket being fitted, which is why a gradual introduction helps.
How much does a PEMF blanket for horses cost in the UK?
Equine PEMF blankets range from several hundred pounds to several thousand for professional systems. The OMI blanket is £799, with the complete pack of applicators at £2,339.
PEMF or red light therapy for horses: which should I choose?
They work differently. Light needs a clean coat and close contact; PEMF passes through coat and fabric. Some yards use both. Our guide to PEMF devices explains the technology in more depth.
Choosing a PEMF blanket for your horse
OMI™ PEMF Blanket for Horses
If you'd like to add PEMF to your yard routine, start with a blanket that states its frequency and intensity clearly and runs on power you can actually get to the stable. Have a look at the OMI™ PEMF Blanket for Horses, or ask us about fit, programmes and power before you buy.
