Vibration Exercisers - The development of vibration training came from a desire to improve bone density and muscle integrity in cosmonauts. The technology was originally developed to counteract the lack of gravity in space by the Soviet Union. After decades of research, vibration machines and hand-held oscillators have received endorsement by many professional athletes and are ensured to produce effective results for your physical therapy and rehabilitation needs. Vibration machines and blades are thought to help increase muscle strength, flexibility and range of motion. They can also help enhance balance and coordination, improve circulation and blood oxygenation, increase bone density and strength, reduce stiffness and much more.
