The role of motion platform on postural instability and head vibration exposure at driving simulators

{This paper explains the effect of a motion platform for driving simulators on postural instability and head vibration exposure. The sensed head level-vehicle (visual cues) level longitudinal and lateral accelerations (a(x,sensed) a(x_head) and a(y,sensed) = a(y_head), a(yv) = a(y_veh) and a(yv) = a(y_veh)) were saved by using a motion tracking sensor and a simulation software respectively. Then, associated vibration dose values (VDVs) were computed at head level during the driving sessions. Furthermore, the postural instabilities of the participants were measured as longitudinal and lateral subject body centre of pressure (X-CP and Y-CP. respectively) displacements just after each driving session via a balance platform. The results revealed that the optic-head inertial level longitudinal accelerations indicated a negative non-significant correlation (r=-.203
