This study was done to validate the results of our previous study [1] as well as analyze how the Soloflex Whole Body Vibration Platform translates vibration to the human body. The purpose of causing vibration within the human body is to increase bone density, possibly by activating osteoblasts within the bone. When the body is subjected to stress, it adapts as quickly as possible to counteract this stress. There is evidence that vibration caused by low magnitude mechanical signals (LMMS) increases bone in children with disabling conditions [2] and young women (15-20 years) with low bone mineral density [3]. Our results show that Soloflex dial settings of 0.8g or greater produce frequencies as expected by the manufacturer. Lower dial settings produce frequencies that are higher than expected values. The results obtained showed that vibration at the foot had no linear association with increased acceleration (R = 0.56, p = 0.20), but vibration frequencies increased with increased acceleration at the hip (R = 0.86. p = 0.01). The mean frequencies measured over the range of accelerations (0.3-1.1g) were not different between the foot and the hip (56 ± 5 vs. 52 ± 12 Hz, p = 0.45; mean ± SD; respectively). Mean frequencies measured at the four different locations on the plate over the range of accelerations (0.3 – 1.1g) were not different when tested by Tukey’s HSD test.
