About

Samuel B. Hopkins is a leading researcher in rehabilitation robotics and assistive mobility devices, with a focus on improving gait for individuals with neurological conditions such as cerebral palsy and stroke. His most impactful work centers on the design and control of adaptive ankle-foot orthoses (AFOs), where he has pioneered the concept of speed-adaptive stiffness. His 2024 paper on a quasi-passive robotic AFO with speed-adaptive stiffness, already garnering 15 citations, addresses a critical limitation of conventional AFOs—their inability to adjust to varying walking speeds. This innovation allows for optimal biomechanical support across different paces, enhancing mobility and comfort for users. Hopkins’ contributions bridge mechanical engineering and clinical rehabilitation, demonstrating how smart materials and passive mechanisms can create lightweight, energy-efficient devices that adapt in real-time. His work has significant implications for personalized assistive technology, offering a path toward more natural and functional gait restoration. By tackling the fixed-stiffness problem, Hopkins is shaping the future of orthotic design, making his research essential reading for engineers and clinicians alike.
