Conditions spatial neglect, aphasia, stroke
Treatment prism adaptation treatment
Phase phase 1/phase 2
Sponsor Kessler Foundation
Start date February 2014
End date December 2016
Trial size 105 participants
Trial identifier NCT02068664, R-802-13


The purpose of this study is to determine if stroke survivors with aphasia have spatial neglect (Phase 1). If they are determined to have the condition Phase 2 will be offered: which is prism adaptation treatment. This is a pilot study that will be performed with 4-5 subjects.

prism adaptation treatment prism adaptation treatment
Prism goggles shift the image one sees toward the left (because the thicker portion of the glass lens is on the right). This will change the perception of where the image is in space, causing the person to adapt. The after-effects of the treatment is what is important. It has been shown to make it easier for people to move in the right space (if have right neglect) or improves ability to complete other functional tasks.

Additional Information

Official title An Assessment of the Prevalence of Spatial Neglect in Stroke Survivors With Aphasia With Option of Prism Adaptation Treatment (PAT) Protocol
Principal investigator Kimberly Hreha, OT
Description Spatial neglect is a disorder that may occur after a brain injury such as stroke. Spatial neglect may affect stroke recovery. One example of this heterogeneous condition: Individuals with spatial neglect often pay more attention to one side of what they are looking at, even though they have no difficulty seeing. The study investigators would like to screen stroke survivors with aphasia because they may also have spatial neglect (right neglect after left hemisphere stroke), which is said by the literature to occur in 25% of cases. If it is identified, a treatment approach will be offered, to attempt to remediate the condition using prism goggles, following a prism treatment protocol based on previous studies.
