Claims of whole body vibration (WBV) have ranged from increasing power, strength, speed, flexibility, bone density, circulation and even balance. However, the findings in all of these areas have been equivocal at best. In the majority of studies, often as a limitation of the vibration platform, the frequency of vibration has ranged between 25-40Hz. It has been posited that the vibration causes the muscle spindle to increase its sensitivity and become primed for easier activation in future muscular contractions. To the area of posture and balance this could potentially result in faster activation of the somatosensory system in response to postural sway. In the current study we are assessing the impact of both frequency and amplitude of WBV on postural control in altered and unaltered sensory environments in healthy younger adults.
