Design and Preliminary Experiment of Head Support Device to Reduce Neck Burden in Overhead Work

Overhead work in many industries causes a heavy burden on the neck because the head is always facing upward, and fatigue tends to accumulate in the neck and shoulders. In order to solve this problem, this study proposes the development of a head looking up posture support device to reduce the burden on the neck during upper overhead work. In this paper, we propose the device together with experiments in which the designed device is attached to a subject and electromyograms are measured. The experimental results show that the device can reduce the burden on the neck.
