First used in the space program to offset the loss of bone strength and muscle mass as a result of minimal gravitational forces, and then in the health industry to reduce the effects of osteoporosis, Whole Body Vibration (WBV) is now widely used in physical therapy and rehabilitation for many conditions and injuries, and as a way to improve fitness in the competing athlete. Vertical vibration improves circulation and increases the oxygen uptake in muscles, helping alleviate pain and inflammation in soft tissue injuries and accelerating hoof growth. Vibration also maintains bone integrity and density when a horse has little or no exercise. We particularly like the TheraPlate's unique 4 Zone Vortex Wave design for its zero impact experience. Under the rubber top there are four separate metal plates, one for each of the horse's legs. Each plate is driven in a planar orbital motion by a separate motor. The controller allows you to vary the frequency of this motion. These fast, tiny motions travel through the entire body, but there is no vertical compression or rocking, so no risk of further injury or aggravating existing conditions. Treatments recommended for a particular issue can be found on the FREE Google Play App - Theraplate.
