The illusionary sensation of movement directly influences motor control through internal models. As a component of perceptual mapping of the limb muscles we are using a modified matching protocol intentional binding to examine how the brain responds to different visualizations of movement with respect to the vibration-induced illusionary input. This will help us to understand which muscles need to be vibrated to most effectively influence motor control. We are developing novel socket designs EMG and Suspension Focused Design, and Vibration Tactor Focused Design capable of integrating vibration tactors while accommodating or improving upon existing function. Gait assessment in amputees is limited because established marker sets placement is not clearly defined for prosthetics. We developed a simplified motion capture Cluster Marker Set that generates sufficiently accurate gait kinematics while allowing fast and easy marker attachment for gait assessment on the CAREN. We developed Sensory Organization Test based modules that will be stacked in an assessment package to provide outcome measures related to balance performance characteristics required to evaluate lower limb prosthesis function. Each module includes standing or walking condition sets and perturbations allowing access to different aspects of balance performance such as balance corrective response strategies and reaction times.
