Do these behaviors ring a bell with you?
Excessive panting when your dog knows you are leaving for work.
Your cat excessively grooming to the point that he creates bald spots in his fur
Anxiety in your horse before competition
Historically, Respond Systems, Inc has focused on PEMF therapy for pain relief, to reduce inflammation and to accelerate healing of both soft tissue and bone. Recently, however, we’ve seen a trend of positive reports of impacts on nervousness and anxiety in animals using the Respond Systems PEMF devices.
While bone and soft tissue healing pioneered the FDA approvals of PEMF, studies within the past decade have shown beneficial effects on the brain, including for treatment of depression and anxiety.
Two recent independent studies reported a reduction in “anxiety-like behaviors” when mice and rats were exposed to PEMF fields (Choleris, et al. Kalkan, et al). Other studies have moved out of the lab animal model to examine effects on human subjects as well. In one study (Martiny et al), the transcranial application of PEMF resulted in a 62% reduction on the Depression Rating Scale for patients suffering with treatment resistant depression.
This research is still young, and we aren’t making any claims of cure with PEMF therapy for the depressed dog or anxious horse. There does seem to be a promising trend that bears watching regarding PEMF’s positive impact on the conditions of those battling these types of mental conditions and illnesses.
For example, Deanna Rogers, PT, CCRP, CCFT, from Good Life Physical Therapy for Animals, shared her experience on the effect of PEMF on one of her geriatric patients.
“I had a very anxious and painful home care patient that I only saw twice who was a 130lb, overweight Malinois. He had severe left groin and knee pain so when I saw him the second time, when he was much worse after battling a tangle with a laundry basket, I recommended he see the vet again. It was the weekend, the vet office was closed, and the owners couldn’t get him in the car by themselves to get him to the ER clinic. So they wanted to manage him at home till that Monday.”
“I gave them my Respond PEMF bed in addition to other things to try. They told me he LOVED the bed at the 5 Hz frequency. They were thinking more is better and tried 15 Hz and he wouldn’t get on the bed. So they went back to 5 Hz and he would go and lie on it and become less anxious.”
For decades, we’ve heard of a similar effect in horses treated with the Bio-Pulse Sentry PEMF Blanket.
Tom Meyers, equine physiotherapist and U.S Team Physio for numerous Olympics and World Games, has been working with PEMF therapy for over 25 years, and had this to say:
“90% of the horses treated with Respond blankets get relief from anxiety. We treated Legolas, Steffen Peters’ (Multi-Time Dressage Olympic and World Game Medalist) horse, with the Sentry blanket before all competitions for his whole career, including World Games, Olympics and World Cup Aachen!”
While a method of activation or biochemical mechanism has not been defined yet, there are a few theories on the pathways PEMF therapy takes to combat depression and anxiety. These include improving neuroplasticity processes (Cichoń et al), decreasing higher EEG frequencies (Amirifalah, et al) and positively impacting the electrical activity of neurons and neurobiological processes effecting local brain activity and connectivity.
Respond will continue to follow the research on the topic as it emerges! In the interim, don’t be surprised if you find yourself using your PEMF equipment to not only promote soft tissue healing and reduction in inflammation, but also for addressing anxiety!
