Pulsed Electromagnetic Field (PEMF) therapy also known as PEME -Pulsed electromagnetic energy is the application of intermittent magnetic field pulses, generated by an electric current flowing through a copper coil(s).
The Science Behind PEMF Therapy:
PEMF therapy involves the use of electromagnetic fields to deliver pulsating energy to cells, tissues, and organs. The electromagnetic fields generated during PEMF therapy are typically low-frequency and have been shown to have therapeutic effects on biological systems.
The main mechanism of PEMF therapy is it influences cellular activity, such as ion transport across cell membranes. Injury can cause a change in the potential difference across the cell membrane. The pulsating electromagnetic fields induce changes in the membrane potential, affecting the distribution of ions such as calcium, sodium, and potassium. These alterations in ion movement can modulate cellular activity and signal transduction helping to restore normal cell function and equilibrium.
Stimulation of cellular signalling pathways including those involving growth factors and cytokines can promote cellular repair, regeneration, and overall tissue healing.
PEMF therapy has an effect on mitochondrial function, including increased ATP production, which is the primary energy currency of cells, meaning increased cellular function.
PEMF therapy has been demonstrated to reduce oxidative stress within cells. By modulating the production of reactive oxygen species (ROS) and enhancing antioxidant defences, PEMF can mitigate cellular damage caused by oxidative stress.
Blood flow is also influenced by PEMF, depending on the Hz used depends on the effect. The most commonly used therapeutic settings have a vasodilatory effect increasing blood flow to the area. The increased circulation facilitates the delivery of oxygen and other nutrients as well as waste removal to and from tissues, helping support the healing process.
PEMF therapy may influence neurotransmitter release and activity. Studies have suggested that PEMF can affect the levels of neurotransmitters such as serotonin, dopamine, and acetylcholine, potentially contributing to its analgesic and mood-modulating effects. PEMF has been shown to modulate brainwave patterns. This neuro-modulation can have implications for cognitive function, sleep quality, and stress reduction.
Benefits of PEMF:
Pain Management: PEMF therapy can provide pain relief for pets suffering from a variety of conditions such as arthritis, soft tissue injuries, neurological conditions. This is achieved by blocking the propagation of the pain signal. It is a useful none invasive tool as part of a pain management program.
Reduces Inflammation and Oedema: Swelling and inflammation can be reduced using PEMF therapy due to its ability to alter the permeability of cell membranes and restore the normal potential difference created via ions meaning the direction of fluid flow is also returned (intra cellular, rather than a higher concentration in the extra cellular matrix).
Enhanced Recovery: After surgery, injury, or illness, PEMF therapy can help speed up the healing process, reducing recovery time and improving the chances of a full recovery this is achieved through multiple mechanisms such as vasodilation. it is often utilised in non-union fractures within human medicine due to these effects.
Stress Reduction/ Increased Stress Tolerance : Many pets experience stress and anxiety, which can lead to various health issues. PEMF therapy has been shown to help alleviate stress, promoting relaxation and well-being. This is achieved by reducing the sensitivity of stress receptors, and melatonin production.
Increased Energy Levels and Performance: By shifting the balance to oxidative processes, energy levels can be increased. Performance can be increased via these mechanisms as well as improved circulation which helps to warm up muscle tissues and help with recovery after sporting events.
Antimicrobial Effects: There is some suggestions that PEMF has an antimicrobial effect.
Depth of Treatment: PEMF is able to penetrate a lot deeper than some other therapies such as LASER, without creating harmful effects to the cells at the surface. Due to the mechanism of travel PEMF waves are able to penetrate between 38-46cms in comparison to LASER which penetrates around 2.5cms. PEMF waves are able to travel through most tissue types without loosing much effectiveness, this makes PEMF therapy perfect for those deeper tissue structures as well as providing a 'whole body' / large area effect, rather than a very specific area as with LASER.
Contraindications:
PEMF is an amazing none invasive therapy with many benefits and uses, however their are certain situation where we should not use PEMF. When should we not use PEMF;
Pregnancy: PEMF is not suitable if the animal is pregnant, we extend this to if any one in the immediate area is pregnant due to the field and multidirectional travel of PEMF waves. Owners or therapists who are pregnant should not be in the same area as an animal being treated with PEMF, you may be asked to leave the room in the case you are pregnant and PEMF is being used on your animal.
Active growth plates: Young animals or those who are still growing should not have PEMF therapy as it can interfere with growth plates and the rate of growth causing issues.
Metal Implants, Pacemakers, or Magnetic/ Electrical Material: PEMF is not suitable if the animal has a pacemaker, a magnetic or electrical controlled devise, and some metal implants or prosthesis, depending on the material they are made out of or if they have a magnet present. PEMF can interfere with these, if a magnet is near the PEMF you will feel the field (this is how we ensure the PEMF device is working).
Epilepsy: animals with epilepsy should not use PEMF therapy this is due to the effect it can have on neurotransmitters and brain waves.
Tumours and Cancer: If an animal has suspected tumours or cancer it is not advisable to use PEMF unless under instruction or approval of a veterinary surgeon. We may get exemptions for this in cases of older animals with multiple conditions, or depending on the location or type of cancer, A vet must approve the use of these in a patient with Cancer.
Caution should also be exercised using PEMF with animals that have acute infections, cardiovascular issues, or respiratory issues.
At Home PEMF:
PEMF is a really useful tool and can be used regularly to help improve overall health and wellbeing, performance and recovery. I will sometimes suggest PEMF as an at home therapy to be used regularly.
