Working as a flight attendant involves significant risks. In this study, JACK Siemens ergonomic tool was used to assess and evaluate the L4/L5 spinal forces associated with pushing and pulling a service trolley. Xsens motion tracking system was used in conjunction with Unity 3D and an Oculus Rift to create a virtual environment of an aircraft. This study revealed that several individual factors, such as body weight and height, had strong correlations with compressive spinal force, as did hip and back flexion. These findings have important implications for developing training programs aimed at reducing the risk of lower back injuries in flight attendants who perform this task on a regular basis.
