The purpose of this research study with a randomized controlled design is to examine the effects of prism adaptation treatment on two visual-spatial recovery components. After a stroke, an "internal GPS", locating where objects or people lie in a particular area of space, may be impaired. Alternately, a stroke may impair precise visual-spatial hand and body aiming movements. The research team wishes to discover whether prism adaptation treatment (two weeks of daily 20-min sessions of goal-directed movement with prism goggles) affects visual-spatial where or aiming errors selectively after stroke.

This research represents one of the first attempts to apply what we know about the brain from neuroscience research, to modern clinical rehabilitation practices.

Primary Outcome Measures:
  • Improvement in Spatial Neglect [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 160
Study Start Date: October 2012
Estimated Study Completion Date: January 2020
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Prism Adaptation Treatment
Two weeks of prism adaptation treatment followed by 4 weekly assessments and long-term follow-ups at the 3rd and 6th months.
Behavioral: Prism Adaptation Treatment
Wearing prism goggles and performing visuomotor tasks during therapy sessions.
No Intervention: Control: Standard Rehabilitation Care
Participants will continue with their standard inpatient rehabilitation care. They will be assessed with cognitive and functional scales for tracking their recovery.
