| Abstract |
One possible contributing factor in fall injuries of heavy mobile equipment operators is a loss of postural stability during egress. Because many of these operators are exposed to prolonged periods of whole-body vibration (WBV), a study was conducted to determine if postural stability is impaired by WBV exposure. The WBV consisted of 40 minutes of vertical vibration generated by a motion platform, which emulated actual vibration levels of an underground shuttle car. Two independent variables, each at two levels, consisted of vibration and vision. The measured dependent variables were postural sway amplitude and velocity of sway. No significant difference between the vibration and no vibration conditions were found. Based on the results of this study, it cannot be concluded that WBV at the exposed frequencies influences postural stability. Other factors may contribute to falls during egress, such as problems with foot placement accuracy or system design. |
