About

Sigal Portnoy is a leading researcher in neurorehabilitation, specializing in post-stroke motor recovery and assistive technologies. Her work bridges the gap between traditional physiotherapy and cutting-edge robotic interventions, with a particular focus on understanding how stroke subtype influences rehabilitation outcomes. In her highly cited 2017 study (34 citations), Portnoy challenged clinical dogma by demonstrating that hemorrhagic and ischemic stroke survivors respond differently to blended conventional physiotherapy with robotic-assisted gait therapy, providing critical evidence that ischemic patients can achieve comparable functional gains to those with hemorrhagic strokes. This finding has significant implications for personalized rehabilitation protocols. Expanding on this theme, her 2019 work (20 citations) examined muscle activity and fatigue patterns in the upper limb during task-specific training versus robot-assisted training, offering valuable insights into the physiological mechanisms underlying different therapeutic approaches. Portnoy’s research is instrumental in optimizing rehabilitation strategies, ensuring that patients receive the most effective, evidence-based interventions tailored to their specific neurological deficits. Her contributions are shaping the future of stroke rehabilitation by integrating biomechanical analysis with clinical practice.
