About

John Jairo Villarejo Mayor is a leading researcher in rehabilitation robotics, specializing in the development of intelligent assistive devices for individuals with neurological and mobility impairments. His work centers on integrating biosignal processing, particularly surface electromyography (sEMG), with robotic control systems to create intuitive, patient-responsive therapies. His most impactful contribution is the design of a robotic knee exoskeleton controlled by motion intention from sEMG signals, using admittance control to assist locomotion for people with reduced mobility—a paper that has garnered 45 citations and is foundational in the field of human-robot interaction for rehabilitation. He has also advanced post-stroke rehabilitation by assessing the applicability of robotic walkers through muscle pattern analysis, offering new insights into hemiparetic gait correction. Additionally, Villarejo Mayor developed a biofeedback system for exoskeleton-assisted gait therapy, enhancing training intensity while reducing therapist strain. His research bridges engineering and clinical practice, aiming to restore autonomy and improve quality of life for patients with motor disabilities. Through these innovations, he has established himself as a key figure in the development of next-generation rehabilitation technologies.
