About

Matthew Krutky’s research lies at the intersection of human motor control, biomechanics, and neurorehabilitation, with a focus on how the nervous system coordinates multi-joint movement and adapts after injury. His most influential work investigates how the brain uses kinematic redundancies—the excess degrees of freedom in our limbs—to regulate stiffness and posture during unconstrained tasks, a paper that has garnered over 100 citations. Krutky made significant contributions to understanding the separate neural control of hand movements and contact forces, a fundamental question in manipulation that has been cited nearly 80 times. His translational impact is particularly evident in stroke research, where he demonstrated that altered stretch reflex coordination contributes to the stereotyped muscle synergies that impair arm function. With over 70 citations, this work bridges basic motor control theory and clinical rehabilitation. Krutky’s studies consistently show that reflex modulation is tightly linked to the orientation of arm mechanics relative to the environment, revealing how the nervous system tunes limb impedance for task success. His research provides a rigorous, mechanistic framework for understanding both healthy motor behavior and post-stroke impairments, making him a key figure in the field of motor neuroscience.
