Research behind the Therapy
Pulsed Electromagnetic Field (PEMF)
In the last 30 years clinicians and scientists have developed a significant volume of research involving cell models, animals and humans demonstrating the biological effects and clinical value of PEMF treatment for a variety of conditions. This research has revealed the significant effects of PEMF treatment in the areas of pain management, mitigation of inflammation, bone healing, and wound healing.
Science has proven that damaged, weak cells caused by stress, injury or overuse have an imbalanced electrical charge. When the voltage of a cell is compromised, the body is unable to rejuvenate itself which is when physical dysfunction manifests. PEMF therapy results in the return of electrical balance within the cell and increases nutrient circulation and oxygen flow. When cells are properly charged and functioning, soreness is reduced, inflammation is decreased, range of motion is increased, stress is reduced, and the body’s restoring abilities are accelerated allowing the horse to perform at its personal best.
The response to PEMF treatment is only observed in injured tissues. PEMF does not cause bone growth or tissue regeneration outside of the context of injured tissue. Therefore, there are no adverse events or detrimental side effects of PEMF treatment.
PEMF mimics the natural electromagnetic fields found throughout nature and operates via a few biological cascades rather than one narrow signaling pathway. PEMF treatment results in increased calcium ion signaling, causing release of intracellular calcium. This leads to increased binding of calcium to calmodulin and a variety of downstream signaling pathways related to metabolism, inflammation, apoptosis, vascular tone among others. Additionally, PEMF induces downstream production of nitric oxide, a vasodilator which influences cells of the immune system and nervous system.
Scientific research and clinical trials in the United Kingdom, Europe, Russia and the United States have investigated the applications of PEMF and have shown excellent rates of success, with no side effects. It is evident that PEMF exposure increases the rejuvenation of bone, muscle, tendon, ligament and skin tissues. The following are a few of the diverse range of therapeutic PEMF applications.
Bone healing
PEMF is associated with faster recovery of load-bearing ability, increased bone formation, and greater mechanical strength of the healing bone. PEMF exposure increases expression of bone morphogenetic proteins 2 and 4, induces osteogenesis and promotes differentiation of osteoblast cells, all of which are required for bone repair.
SOFT TISSUE WOUND HEALING
PEMF accelerates the healing of chronic wounds, it enhances blood flow and increases production of growth factors for repairing tissue. Research has shown that PEMF exposure can accelerate growth of new blood vessels by 5-fold. It enhances vascular performance and vascularization and associated tissue perfusion and oxygenation which are all important for wound repair. Further, PEMF drives the release of the growth factors that support neovascularization, tissue regeneration and tissue remodeling. Clinical findings of increased tensile strength at tendon repair sites have been reported. Additionally, PEMF exposure has shown to result in a significant reduction in wound infection, inhibits bacterial growth and production, decreases staphylococcus aureus colony forming units, and stimulates macrophages and body immunity.
INFLammation, PAIn and EDEMA
PEMF induces gene expression changes associated with resolution of inflammation and has shown to result in production of low concentrations of nitric oxide, which are associated with diminished inflammation and enhancement of vasodilation. PEMF treatment lowers pain levels and results in lower concentrations of inflammatory biomarkers and improved proprioceptive function. Clinical findings of reduced pain, swelling and inflammation have all been reported through the use of PEMF therapy.
health and wellbeing
PEMF results in the improvement of quality of life and decreases clinical signs of degenerative disease, decreases overall pain and improves function. PEMF treatment results in the upregulation of nitric oxide production which reduces inflammatory gene expression in immune cells, reduces programmed cell death, and promotes dilation of blood vessels and enhances circulation. After injury, pro-inflammatory cytokines are quickly released imitating a complex inflammatory cascade, this response helps ward off infection and reduces use of the affected area. Further, PEMF stimulates bacteriostasis and enhances overall body immunity.
PSYCHiatric and NEUROLOgical
PEMF therapy helps improve mood and behavioral disorders. It has been shown to reduce inflammatory cytokine production in the brain and promotes brain healing. Further it has been reported to reduce clinical signs of depression and anxiety.
