PEMF Therapy for Large Animals (Equine): An Expert Discussion on Performance and Recovery 

Champion Horses and Cutting-Edge Therapy

In the world of competitive equine athletes, every advantage in recovery counts. After a grueling cross-country course or an intense showjumping round, top equine veterinarians and trainers turn to Pulsed Electromagnetic Field therapy to help their horses rebound. Dr. Michael Roberts, DVM, an equine sports medicine expert, shares that he uses PEMF on his competition horses as part of the cool-down routine. “You can actually see the horses relax – sometimes they even yawn or lower their heads – when we apply the PEMF coils along their back and legs,” he says. The goal is to reduce muscle soreness, inflammation, and fatigue after strenuous exercise. Many in the industry echo Dr. Roberts’ approach. In fact, a recent survey of the equine industry revealed that an overwhelming majority of performance horse owners and caretakers are using PEMF: over 85% of riders had tried PEMF therapy on their performance horses, and 96% of trainers/grooms reported using PEMF on horses under their care. Most observed positive effects, often within a day of treatment, such as calmer behavior and improved comfort. This widespread adoption speaks to PEMF’s reputation as a trusted tool for equine recovery and wellness. 

Enhancing Recovery and Managing Injuries

What can PEMF do for large animals like horses? Dr. Roberts explains that the therapy’s benefits are multi-fold. By pulsing magnetic fields into tissues, PEMF improves circulation and reduces inflammation in a horse’s muscles, joints, and tendons. “After a hard workout, one PEMF session can help flush out lactic acid and reduce swelling. It’s like an electro-massage at the cellular level,” he notes. For injured horses, PEMF is used to support healing of soft-tissue strains or even bone injuries. The technology originally gained foothold in equine medicine decades ago when studies showed it could aid bone repair – a 1980s study on young ponies suggested PEMF modestly sped up the incorporation of bone grafts in healing fractures. Today, anecdotal reports abound of faster tendon and ligament healing when PEMF is added to rest and conventional therapy. 

One high-profile area of interest is arthritis and chronic lameness in horses. Osteoarthritis is a leading cause of diminished performance in older equine athletes. Encouragingly, emerging research indicates PEMF might help manage these issues. In an Equine Science symposium presentation, researchers found that a single PEMF treatment temporarily reduced lameness and lowered inflammatory cytokine levels in horses with arthritis, about one hour post-treatment. The treated horses showed a short-term improvement in pain indicators, though the effect faded by the next day. “This hints that PEMF can reduce pain and inflammation in the short term – which is fantastic for post-workout recovery – but it also tells us we need to apply it consistently for lasting benefits,” Dr. Roberts explains. Indeed, experts agree that regular PEMF sessions (for example, before and after competitions, or several times a week during rehab) may yield the best outcomes in controlling inflammation and promoting tissue repair in horses. Consistency is key: just as with conditioning exercises, the biological effects of PEMF are cumulative and protocol-dependent. 

Science, Safety, and Standardization 

Despite the enthusiasm, veterinarians remain grounded in evidence. Dr. Roberts points out that while plenty of positive case studies and small trials exist, large-scale research in horses is still catching up. The good news is that what has been learned in human and small-animal studies often carries over to equines. For instance, PEMF’s known effects include enhanced microcirculation, reduced inflammatory mediators, and stimulated cellular repair, as documented in various species. These translate well to the physiology of horses. Moreover, safety studies and decades of practical use indicate that PEMF is very safe for large animals – it’s non-thermal and non-invasive, causing no discomfort. Horses typically stand quietly during treatment, often untethered, because they find it tolerable or even soothing. Standard precautions are simple (avoid using PEMF over an area of acute hemorrhage or in pregnant mares, similar to small-animal guidelines). 

A recurring theme in the field is the need for standardized treatment protocols. The equine research presented by Colorado State University highlighted that there is “no one-size-fits-all” yet – their trial used a certain power and duration based on what horses would tolerate. Some studies with very low-intensity PEMF showed minimal effects, whereas practitioners using higher-powered systems often report more dramatic improvements. To address this, ongoing studies are examining different frequencies, intensities, and session lengths to optimize outcomes for conditions like tendon injuries or back pain in horses. Until then, vets like Dr. Roberts rely on experience: “We might do a 30-minute session at a moderate setting for general recovery, but for a specific injury like a bowed tendon, I’ll use a targeted loop daily on a higher setting per the manufacturer’s guidance.” 

Magnus Magnetica: Leading Equine PEMF Technology

Behind many of the PEMF units seen at barns and equine hospitals is the innovation of companies such as Magnus Magnetica. Magnus Magnetica has been a pioneer in equine PEMF therapy, marketing FEI-compliant PEMF devices for horses since 2007. This means their equipment meets the strict safety standards of the international equestrian federation, so it can even be used at competitions without violating regulations – a critical factor for professionals. The company’s flagship EquiPulse systems are well-known in the horse world; Dr. Roberts mentions that his clinic uses a Magnus Magnetica unit because “it’s robust and built for barn conditions, yet also finely tunable.” The ability to adjust intensity and use large loops (to cover a horse’s big muscle groups) or smaller attachments (for legs and hooves) is a result of Magnus Magnetica’s design innovations. Additionally, in 2021 the company achieved FDA Establishment Registration for its manufacturing – a first among high-powered PEMF device makers in the U.S. – reflecting their commitment to quality and safety. This kind of progress is paving the way for more clinical research, too. Magnus Magnetica has supported studies, including collaborations with veterinary schools, to further validate PEMF for equine therapy. 

In Dr. Roberts’ view, the partnership between veterinary expertise and industry innovation bodes well for horses: “We have the know-how and the tools. With leaders like Magnus Magnetica continually improving PEMF technology, my hope is that in a few years, we’ll have even more evidence-based protocols. But even now, I’ve seen enough in my practice to be confident using PEMF daily. It keeps our horses feeling their best and shortens downtime when injuries happen.” For competitive and working horses, that edge can make all the difference – the power to heal, recover, and perhaps extend their athletic careers, all thanks to a therapy that harnesses physics in service of physiology.
