About

Karim Hajjar’s research lies at the intersection of neurorehabilitation, robotics, and precision medicine, with a primary focus on developing objective biomarkers for motor recovery after stroke. His landmark 2013 paper, cited 156 times, demonstrated that robotic measurement of arm movements can establish reliable biomarkers of motor recovery, offering a high-resolution, quantitative alternative to subjective clinical scales. This work fundamentally advanced how researchers and clinicians track neurological recovery, providing a foundation for more rigorous clinical trial design. In his more recent 2021 study, Hajjar extended this approach by showing that robotic kinematic data can accurately predict standard clinical stroke scales and improve biomarker sensitivity, directly addressing the challenge of human rater variability in endpoint measurement. His contributions are particularly notable for bridging engineering and clinical neuroscience, translating sophisticated robotic metrics into actionable tools for rehabilitation assessment. Through these innovations, Hajjar has helped pave the way for more objective, data-driven stroke rehabilitation protocols, making him a key figure in the growing field of technology-enabled neurological assessment.
