Researchers from the Medical University of Vienna, working with collaborators from ETH Zurich, the Technical University of Munich, and the University of Belgrade, have developed a wearable neurorobotic system designed to restore hand function in people with severe neurological impairments. The system combines a lightweight robotic hand exoskeleton with functional electrical stimulation (FES), which activates weakened muscles through carefully timed electrical impulses. By synchronizing robotic assistance with the user's own muscle activity, the device enables more natural and coordinated grasping and finger movements than conventional rehabilitation approaches.
The researchers evaluated the system in individuals with spinal cord injuries and stroke-related hand paralysis, demonstrating significant improvements in performing everyday tasks such as grasping and manipulating objects. Unlike existing rehabilitation devices that often rely solely on robotics or electrical stimulation, the hybrid approach leverages the strengths of both technologies, promoting functional recovery while encouraging active patient participation. The team believes the wearable system could support both clinical rehabilitation and home-based therapy, offering a practical solution for improving independence and quality of life for people with impaired hand function.
