Abstract

Visual fidelity influences many aspects of daily living, including stabilizing wrist movements against environmental perturbations. Here, we present a pilot investigation to determine how visual feedback impacts wrist stabilization for populations with age related declines in motor function and chronic stroke. To quantify these interactions, behavioral performance and local brain activation were observed during a task requiring stabilization of the wrist against constant and stochastic extensor torque perturbations. All subjects were better able to stabilize their wrist when veridical visual feedback of their limb was provided. Examination of the neural activation maps in the Control and Aging populations revealed patterns of neural activity commonly associated with feedback control of limb position. The Stroke survivor, however, exhibited a different pattern of neural activity, possibly due to the lack of sensory feedback employment.
