Title: Feasibility and Effectiveness Study of Implementing Prism Adaptation as a Treatment for Spatial Neglect After Right Hemisphere Stroke
Brief Summary: Spatial neglect is a common attention disorder after right hemisphere stroke and is associated with decreased independence and quality of life. Despite its high prevalence in the stroke population, there is currently no standard of care for the treatment of neglect. Prism adaptation (PA) is a promising rehabilitation technique, however incorporation into clinical care has been limited likely due to the lack of standardized procedures. The investigators have developed a computerized PA technique designed to better engage patients and assist clinicians. In this study the investigators aim to evaluate the feasibility and effectiveness of the computerized PA procedure in a typical health care setting, with the hypothesis that the PA procedure will improve patient's neglect symptoms.
