Your body is programmed with different reflexes, like blinking your eye. A deep-tendon stretch reflex occurs when an examiner taps your knee with a hammer and your leg extends one tap, one contraction. In contrast, whole body vibration therapy induces a continuous stretch reflex called the Tonic Vibration Reflex.The vibrating platform causes minute stretches within the muscles that activate this reflex. Because WBV platforms vibrate from 30-50 times per second (30-50 Hz) and in 3 dimensions, these involuntary muscle contractions occur at this accelerated rate as well. This corresponding body response also means that the deep postural and stabilizing muscles, that are difficult to rehabilitate, can be safely and effectively addressed.
