About

Chee Leong Teo is a researcher whose work sits at the intersection of rehabilitation robotics, assistive technology, and human-machine interaction. His most significant contributions center on the development and clinical evaluation of robotic devices designed to restore upper limb function in stroke survivors and individuals with neurological conditions. Most notably, Teo played a central role in the HapticKnob project — a two-degree-of-freedom robotic interface for retraining hand grasping and forearm pronation/supination — which has garnered over 196 citations and inspired subsequent clinical trials demonstrating measurable functional improvements in chronic stroke patients. His longitudinal pilot studies, accumulating over 145 additional citations, helped establish the feasibility of end-effector-based robotic rehabilitation for distal upper limb joints, an area historically underserved by research. Beyond hand rehabilitation, Teo has made meaningful contributions to intelligent wheelchair systems, developing the Collaborative Wheelchair Assistant (CWA), which blends user intent with automated path guidance — work that has been evaluated across populations including cerebral palsy and traumatic brain injury users. His more recent efforts extend into pediatric rehabilitation robotics and EMG-driven human-machine interfaces. Across his portfolio, Teo's research reflects a consistent commitment to translating engineering innovation into clinically meaningful assistive and rehabilitative solutions.
