Development of a Simple Wearable Device Capable of Keeping a Half-crouching Position

Abstract

There are a lot of caregivers who suffered lumbar pain. Although the main cause is thought to be transfer aid, meal assistance also cause the lumber pain because this assistance import burden on the lumber spine for a long time. Therefore, we develop a wearable device which can reduce load on the lumber spine in this research. The device under development can keep a halfcrouching position with using exoskeleton mechanism, so that flection of the spine is diminished during work and stress of the intervertebral disc is decreased. Because the device adapts linear mechanism for increase manipulability of legs, it has an advantage over the other developed exoskeleton device.
