Stairs and curbs often present as an exhausting environmental barrier for individuals with bilateral cerebral palsy (CP) due to their lower limb motor impairments. Indeed, performance in stair-climbing in this population has a higher correlation with disruption of mobility than walking. Community members affected by CP consider impaired mobility a...
Assistive robots have the potential to support motor recovery after an injury as well as to alleviate the burden of physical tasks for both impaired and able-bodied individuals. Over the last few decades assistive robots have become increasingly more capable. Many can now provide task-specific assistance and can be safe...
Visual information plays a critical role in controlling movement. People use visual information to plan future actions and correct current actions through feedforward and feedback processes, respectively. We can gain insights into these visually guided motor control processes by quantifying where people look during movement and measuring how much they...
Simple sensorimotor tasks, such as lifting a cup or balancing a tray, requires not only controlled motor output, but also the ability to accurately perceive sensory information. After a hemiparetic stroke, individuals often experience sensory deficits in addition to motor impairments. However, research on the extent of changes in sensory...

Before initiating a walking movement, the central nervous system forms a motor plan, a set of motor commands predicted to accomplish task-specific goals. To be effective, motor plans must be continually updated to consider an ever-changing external environment. Despite being an inherent part of walking, how the nervous system adapts...
Humans have a remarkable ability to create stable walking patterns that can resist and recover from perturbations. Unfortunately, this ability is substantially impaired after a stroke, limiting mobility and contributing to a high fall rate. To facilitate gait training during post-stroke rehabilitation, clinicians often incorporate body-weight support (BWS) systems that...
