Abstract: An advanced fusion technology has been investigated to evaluate the injury risk in the healthcare sector by integrating a motion tracking system with digital human modelling (DHM) ergonomic tools. The proposed approach greatly overcomes the time-consuming process to create a full-body dynamic simulation where the DHM postures are set manually. This study provides a new method to evaluate the lumbar forces and physical demands for individuals during healthcare operations. In this study, we analysed the effect of key anthropometric and biomechanics variables on the low back loadings, such as body weight, body height, trunk and hip angular displacements, as well as genders. The relationship of such variables to the lumbar spine forces may provide insights on the occurrence of musculoskeletal disorders during patient handling tasks. The outcomes of this study can directly result in the design of better assistive device and workstation as well as the development of enhanced injury prevention programs.
