An international team of researchers has designed a wearable lower-limb robot exoskeleton to help patients with stroke and spinal cord injury walk again.
The wearable robot, developed by scientists from Beihang University in China and Aalborg University in Denmark, features natural knee movement to greatly improve patients comfort.
It has been designed to help stroke patients strengthen their physical fitness, aid the rehabilitation training of paralyzed patients, or to assist those who need help performing daily activities.
Our new design features a parallel knee joint to improve the bio-imitability and adaptability of the exoskeleton, said Weihai Chen, a professor at Beihang University, who was involved in the research.
To improve the transparency of the robot, we studied the structure of the human body, then built our model based on a biometric design of the lower limb exoskeleton, the researcher added.
Unlike previous exoskeletons, which simplified the knee joint as a pin joint, the new innovation provides 2-DOF to make the exoskeletons movement consistent with a patients natural movement.
The research was published recently in the journal Review of Scientific Instruments.
