The purpose of this study was to provide a practical guide to the proper way of lifting a patient using various types of stretcher that rescue crews use by analyzing the load on the lumbar region. The experiment was conducted with working male and female rescue crews. Having mixed groups of gender complete tasks such as lifting, moving, and unloading a patient using four different types of stretcher, we recorded variations of the lumbar bending angle and calculated the load on the lumbar region using 3D SSPP. The data showed, in terms of the lumbar bending angle, it was greater when only females were involved in the work, and there were very significant differences in the angle depending on the types of stretcher used and body sizes of each subject. In the analysis of the load on the lumbar based on the bending angle, NIOSH was over the recommended limit in certain groups. Utilizing the analysis, it is recommended, in the medium and long term, to improve equipments for rescue personnel and to guide them to the proper way of working.
