STORY AT-A-GLANCE
- Pulsed electromagnetic field (PEMF) therapy interacts with body tissues, aiming to stimulate natural healing in muscles, bones, tendons, and joints in pets
- The therapy works by restoring electrical cell signals disrupted by injury or illness, reducing inflammation, improving circulation, and supporting tissue repair and growth
- Veterinary applications include treating osteoarthritis, bone fractures, soft tissue injuries, intervertebral disc disease (IVDD), post-operative pain, and wounds
- Treatment sessions typically last 10 to 60 minutes on a therapy mat or with a loop device, which is done daily or several times weekly. Improvements develop gradually over several days to weeks
- PEMF therapy is noninvasive and generally safe, but is unsuitable for pets with pacemakers, pregnancies, or active infections, and works best as part of a broader treatment plan
Watching your dog or cat deal with pain, stiff joints, or slow healing after an injury is hard, and as a pet parent, you naturally want to do everything you can to help them feel better right away. Now, a novel solution has entered the picture — pulsed electromagnetic field (PEMF) therapy.
PEMF has gained attention in veterinary medicine in recent years, as integrative veterinarians and pet parents believe it can help reduce pain, improve mobility, and support healing. But what exactly is it? And more importantly, could it really help your pet?
The Basics of PEMF Therapy
While the name may sound complicated, the basic idea is fairly simple. A PEMF device sends gentle magnetic pulses into the body using an electrical current. These pulses create electromagnetic fields that interact with tissues in the muscles, bones, tendons, and joints with the goal of stimulating natural healing processes in the body. PEMF devices may come in different forms, including:
- Therapy mats or beds your pet lies on
- Small loops placed over an injured area
- Wearable jackets designed for animals
- Portable home-use devices
Each device produces electromagnetic pulses at specific frequencies and strengths. These differences can influence how deeply the fields penetrate the body and how they affect different tissues and create healing.
While PEMF therapy is becoming more popular, it is still considered an emerging therapy, and research is ongoing to fully understand how well it works.1
How PEMF Therapy May Support Healing
To understand how PEMF therapy may help your pet, it is vital to know how your pet’s body functions. Your pet’s body relies on tiny electrical signals to control many processes. These signals help regulate nerve communication, muscle movement, heart rhythm, and cell repair and growth.
The electrical signals occur because cells contain charged particles called ions. When these move, they create small electrical currents that, in turn, also produce magnetic fields. These fields exist naturally throughout the body and play a role in how cells communicate with one another.
When injury, aging, or illness disrupts the communication, cells may not function as efficiently. With this in mind, PEMF therapy aims to help restore these signals so that cells can communicate and heal more effectively. Researchers believe PEMF therapy may influence several important processes inside the body. These include:2
- Reducing inflammation — PEMF therapy may help lower inflammation levels in tissues, which could reduce pain and swelling.
- Improving circulation — Better blood flow means tissues receive more oxygen and nutrients.
- Supporting tissue repair — PEMF therapy may stimulate cell growth and collagen production, which are essential for healing tissues like muscles, ligaments, and skin.
Application of PEMF Therapy in Veterinary Settings
PEMF therapy has been studied among humans for decades. In 1979, the U.S. Food and Drug Administration (FDA) approved it for non-union bone fractures and stimulating bone growth. As of 2019, it has been approved for adjunctive treatment of postoperative pain.3
Naturally, veterinarians became curious about using PEMF therapy in animals. They found out that it has been able to help in the following conditions:4,5,6
- Osteoarthritis — One of the most common joint conditions in dogs, causing joint pain, stiffness, and reduced mobility. Considering this, PEMF therapy may help improve mobility and reduce discomfort in dogs with osteoarthritis by supporting joint health and reducing inflammation.
In a study published in BMC Veterinary Research,7 scientists followed dogs with chronic osteoarthritis over six weeks. They received PEMF therapy and showed improvements in walking symmetry and movement by the end of the study period, suggesting improved joint function and reduced pain.
- Bone healing — As noted earlier, PEMF therapy has been studied for its ability to help support bone healing, especially in fractures that are slow to heal.
- Soft tissue injuries — Affected areas involve muscles, tendons, and ligaments. PEMF therapy may help reduce inflammation and support tissue repair, making it a possible supportive treatment for these types of injuries.
- Intervertebral disc disease (IVDD) — This occurs when the discs between spinal bones become damaged or slip out of place, causing pain and nerve problems. According to VCA Animal Hospitals, PEMF therapy can help support nerve protection and healing in these cases, although careful monitoring is required because certain situations could worsen with improper treatment.8
- Post-operative pain management and healing — Numerous studies on both the human and animal sides have shown benefit when PEMF is used post-operatively both for speeding the healing of the incision and for reducing pain.
- Wound healing — PEMF therapy may help support circulation and tissue regeneration. Better blood flow can help deliver nutrients and oxygen to injured tissues, which are essential for recovery.
What a Typical PEMF Treatment Looks Like
Many veterinary rehabilitation centers offer PEMF therapy as part of physical therapy programs. If your veterinarian recommends it, treatments may take place either in a veterinary clinic or at home.
Your pet will lie on a therapy mat or bed that emits gentle electromagnetic pulses. Another method is using loops placed around specific joints or injuries. Treatment sessions can vary depending on the device and condition being treated. In many cases, sessions last between 10 and 60 minutes and may occur daily or several times per week.
One important reminder is that PEMF therapy often works gradually, although some pets may experience pain relief after a single session. Either way, long-term improvements typically develop over several weeks as healing processes continue in the body. Several factors influence how quickly your pet may respond, such as:9
- Their age
- Overall health
- Activity level
- Severity of the condition
- Any other ongoing adjunctive treatments
Is PEMF Therapy Safe?
PEMF therapy is appealing to many pet owners because it is noninvasive and does not require surgery, injections, or medications, making it generally safe to use. However, there are some situations where it is not ideal, such as:10
- Your pet has a pacemaker or electronic implant
- Your pet is pregnant
- There is an active fungal infection
- There is uncontrolled bleeding in the treatment area
If you are considering PEMF therapy for home use, it is important to understand that not all devices are the same, as mentioned above. They vary in strength, frequency, and treatment design. Important factors to consider include:11
- The intensity of the magnetic field
- The range of frequencies available
- Device quality and reliability
- Support from the manufacturer
- Veterinary guidance
Your veterinarian can help you choose a device that is appropriate for your pet’s condition. But again, remember that PEMF therapy is rarely used alone — it is often a part of a broader treatment plan,12,13,14 which includes weight management, exercise programs, and physical therapy sessions. Using multiple approaches together can often provide the best results for chronic conditions like arthritis.15
