About

Pang Hung Lim is a leading figure in rehabilitation robotics, specializing in the design and control of robotic exoskeletons and overground gait training systems. His work directly addresses the critical challenge of restoring walking ability in individuals with stroke and spinal cord injury (SCI). Lim’s most significant contribution is the development of the "NaTUre-gaits" (Natural and TUneable rehabilitation gait system), an innovative overground gait rehabilitation robot. This system, detailed in his most-cited paper (36 citations), uniquely integrates robotic orthoses with a pelvic arm and mobile platform to replicate the benefits of manual-assisted training while allowing natural, overground ambulation. He further advanced the field by tackling the "open question" of exoskeleton balance, proposing a novel balance stabilizer mechanism in a subsequent highly-cited work (20 citations). His research has demonstrated tangible clinical impact, with studies involving both healthy subjects and SCI patients showing the positive effects of ground contact during robotic-assisted walking. By focusing on both the mechanical design and the critical control challenges of stability, Lim has laid essential groundwork for making robotic gait training safer, more effective, and more accessible for patients with severe motor impairments.
