Decompression motion support for the prevention of pressure ulcers using exoskeleton robot

We previously proposed a motion assist robot and conducted experiments with a C5-level cervical cord injury patient. In this paper, we support decompression motion support to prevent pressure ulcers in C5 level cervical cord injury patients. Many types of wearable robots use motors, and there can often be issues with safety. Accordingly, we developed an active cast that can lock/unlock the user´s elbow joint. When they compress their hip, we fix the angle of the elbow joint to make a rigid model of 3 links. As a result, our subject was able to disperse pressure by about 30% when sitting in a wheelchair.
