About
Justin Drogos is a leading researcher in stroke rehabilitation, whose work centers on understanding and treating upper limb motor impairments, particularly the debilitating loss of independent joint control known as **flexion synergy**. His major contributions lie in characterizing the neurophysiological mechanisms behind this abnormal muscle coactivation—demonstrating how neuromodulatory inputs to motoneurons and modified stretch reflexes contribute to weakness and impaired reaching. Drogos is perhaps best known for developing and testing **Progressive Abduction Loading Therapy (PALT)** , a novel intervention that systematically targets flexion synergy to restore function. His landmark 2018 randomized clinical trial (62 citations) showed that PALT significantly improves upper limb function in chronic hemiparetic stroke survivors. With over 200 total citations, Drogos’s work has reshaped clinical understanding of post-stroke motor control, bridging robotic assessment (e.g., the ACT-4D device) with targeted therapy. His ongoing research continues to explore device-assisted practice of activities of daily living, aiming to translate these insights into accessible, high-impact rehabilitation protocols for individuals with moderate to severe stroke.
