Title: Addressing post-stroke Stiff-Knee gait using biomechanics,neurophysiology, and robotics

Abstract: Stiff-Knee gait (SKG) after stroke is vaguely defined as reduced knee flexion during the swing phase of walking. People who cannot elicit enough knee flexion must compensate in other ways, leading to fatigue, pain and balance issues. The cause of SKG is much debated, as is its definition. In this talk I will describe our ongoing work showing that not all definitions of SKG are the same, that a likely cause is hyperreflexia of the rectus femoris from lack of spinal presynaptic inhibition, and posit a novel approach using exoskeletal assistance and self-regulation of reflex excitability. My underlying hypothesis is that dividing and conquering weakness and hyperreflexia using multidisciplinary approaches will help restore healthy gait post-stroke.
