胸部支持機構を用いた中腰姿勢支援装具の開発

抄録

Lumbago may be caused by the muscle fatigue and muscle tension of the erector spinae in the Half-Crouching Position[HCP]. In this study, we developed a HCP supporting device to maintain the HCP by supporting the chest with structural materials without using power and suppress the muscle activity of the erector spinae. In addition, since the reaction force to the chest is not oriented in the compression direction of the lumbar intervertebral disc, it can be considered that the load of the intervertebral disc by the device is suppressed. Furthermore, we could confirm reduction of activity of the erector spinae muscle by equipping the HCP supporting device from ARV.
