  • Proposal of ground contacting type assistive device for lifting heavy objects aimed to prevent low back pain

抄録

<p>Low back pain is a typical occupational illness, and wearable assistive devices have been studied for its prevention. These wearable assistive devices assist extension of the waist or hip joint, however, they can not assist other joints such as elbow. Also, wearer has to support the weight of the device itself during an action other than lifting-up motion such as walking. In this research, to solve the problem above, a ground contacting type assistive device which assists lifting-up motion is proposed. The proposed device aims at a lightweight construction and high assist efficiency by letting the weight of the heavy object transmit directly to the ground. In this paper, we describe the concept, and the effectiveness of the proposed method is verified by ex0periment with a prototype.</p>
