No clinical device simply yet effectively reduces loads placed on the lower back. We report on a prototype device developed for practical use that reduces the load on the low back. This paper discusses the theoretical analysis based on a mechanical model, motion analysis by measuring joint angle variations in typical nursing movements and the evaluation of the exertion encountered in nursing from EMG signals of the erector spinae when loads are applied. In addition, the device was tested to evaluate the device's potential restrictions to daily activities, i.e. walking and sitting on chair. The results showed that the device does not constrain body movement and that the required exertion of subjects to support a large load is substantially reduced by use of the device, especially in the deep fore-leaning posture as targeted.
