抄録

Various lifting motions are expected at work sites, and lifting heavy luggage may cause lower back pain. Work-related back pain is a severe problem worldwide. In addition, the number of lower back pain is increasing. Therefore, Authors developed the lower back assistive device with pneumatic assistive system to reduce the rate of lower back pain cause. This device is lightweight to reduce the burden during lifting motions because it does not have external power supply such as battery or air tank. In this paper, we have developed a lower back assistive device that is suited to the actual conditions of the workplace by generating assistive force in accordance with human movements, adapting the device to various body sizes, and reducing the mass of the device to enhance the assistance effect.
