PEMF, massage, laser, kinesiology taping, acupuncture, and many more are all modalities used in the treatment of equine injuries or illness in efforts to rehabilitate the horse, or to maintain a healthy horse's condition. I believe that the use of multiple modalities increases the horses chances of full recovery in many cases, and can even reduce the time required for recovery significantly. BEMER therapy is my go-to modality of choice due to its effectiveness, on my own personal horses and client horses, and its wide range of applications. BEMER treats the whole horse as it literally impacts all systems of the body (cells and circulation), helping the horse heal itself. 

As with ANY treatment or therapy, you should always consult with your Veterinarian beforehand.
