Prism Adaptation Therapy (PAT) for Right Brain Stroke Rehabilitation

After a right brain stroke, \>50% of Veterans experience problems with dressing, eating, self-care or steering their wheelchairs because their ability to move, orient, and respond toward the left side is limited: spatial neglect. Spatial neglect prevents them from functioning independently, and their needs in the hospital and at home are greatly increased. An effective treatment for spatial neglect is 10 days of visuomotor training while wearing optical prisms (PAT), however many clinicians \[fail to diagnose spatial neglect and use this approach. In this study, the investigators will develop a brain scanning test that could objectively identify the Veterans with spatial neglect after stroke who are the best candidates to receive PAT and recover their ability to function. When the research is complete, the investigators expect that brain scans done in the hospital can guide the team to refer Veterans to PAT rehabilitation: improving daily life function\] and quality of life.
