Title: The transmission of vertical whole body vibration with different frequencies and postures in older adults
Abstract: Background: Increasing research evidence suggested that whole body vibration (WBV) could enhance physical functioning in elderly population. Studying the transmission of the vibratory signals is important, because the therapeutic effect should be highly related to the intensity of the vibration reaching the target treatment area. There are also safety considerations, as potentially destructive resonance and transmission of the vibrations to the head should be minimized. To date, there is a lack of research investigating the transmissibility of WBV and how it is affected by various vibration frequencies and posture in the elderly population.
