About

Dr. Yee Sien Ng is a leading figure in rehabilitation robotics and neurorehabilitation, whose work bridges engineering and clinical medicine to restore mobility after stroke. His research centers on developing intelligent robotic systems and brain-computer interfaces (BCIs) for gait rehabilitation, with a strong emphasis on translating these technologies from the lab to outpatient and home settings. Dr. Ng’s most impactful contribution is his pioneering work on neural network control for rehabilitation robots, detailed in his highly cited 2014 paper (253 citations), which enables state and output feedback for safer, more responsive therapy. He further advanced the field by demonstrating that transcranial direct current stimulation can significantly enhance motor imagery-based BCIs with robotic feedback for stroke recovery (157 citations). Notably, he led the mechanical design of a portable, modular knee-ankle-foot robot featuring a novel compact compliant actuator, aimed at delivering intelligent gait training outside clinical environments. His work also includes developing impedance control strategies for interactive training and using EEG coherence analysis to measure motor recovery patterns. With a portfolio of papers accumulating hundreds of citations, Dr. Ng’s research is shaping the future of accessible, technology-driven rehabilitation medicine.
