What is PEMF therapy?

PEMF stands for Pulsed Electromagnetic Field therapy. It's a non-invasive treatment that uses controlled magnetic pulses to stimulate cellular repair, reduce inflammation, and restore normal cell function in your horse's body. Think of it as a tune-up at the cellular level.

How does PEMF work?

Every cell in your horse's body carries an electrical charge. When cells are damaged — through injury, overwork, or age — that charge drops, and the cell can't function properly. Waste builds up, nutrients can't get in, and inflammation sets in.

PEMF therapy sends brief, powerful magnetic pulses into the tissue. These pulses pass through skin, muscle, and bone to reach cells deep in the body. The energy from each pulse restores the cell's natural electrical charge, which in turn:

• Increases blood flow — more oxygen and nutrients reach the damaged area
• Reduces inflammation — swelling decreases as cells can flush waste products
• Accelerates tissue repair — bones, tendons, ligaments, and muscles heal faster
• Relieves pain — by addressing the cause, not just masking symptoms
• Promotes relaxation — most horses visibly lower their heads and relax during treatment

PEMF is not the same as a magnetic blanket

Static magnets and magnetic blankets produce a constant, low-level field. They may offer mild comfort, but they lack the power to drive cellular change. Professional PEMF devices like the Magna Wave generate pulsed fields at significantly higher intensities — strong enough to penetrate deep tissue and stimulate real healing at the cellular level. The difference is comparable to holding a flashlight versus a searchlight.

Is PEMF safe?

PEMF therapy has been used in human medicine since the 1970s and was approved by the FDA for bone healing in 1979. It has an excellent safety record in both human and veterinary applications. The treatment is completely non-invasive — there are no needles, no drugs, no sedation, and no recovery period. Your horse can return to normal activity immediately after a session.

The only contraindication is pregnancy — PEMF should not be used on pregnant mares. For all other horses, PEMF is considered extremely safe when administered by a trained practitioner.

What conditions does PEMF treat?

PEMF therapy is effective for a wide range of equine conditions, both acute and chronic. The most common conditions we treat include:

• Arthritis and joint stiffness
• Laminitis and hoof conditions
• Back pain and soreness
• Tendon and ligament injuries
• Post-competition recovery
• Navicular syndrome
• Wound healing
• Bone fractures
• Muscle spasms and tension
• General stiffness in senior horses

The science behind PEMF

Research published in peer-reviewed journals has demonstrated that PEMF therapy increases microcirculation, upregulates growth factors involved in tissue repair, and modulates inflammatory cytokines. A 2022 study published in the journal Animals found that PEMF was one of the most commonly used complementary therapies among equine practitioners, with the majority reporting positive outcomes for musculoskeletal conditions.

While research specific to equine PEMF is still growing, the underlying mechanisms — improved cellular energy, enhanced blood flow, and reduced inflammation — are well-established in the broader bioelectromagnetics literature.
