Research summary
Visual neglect commonly occurs following a stroke and is defined as the inability to acknowledge things on one side. Many pen-and-paper screening tools are available to test for visual neglect, one of them being the star cancellation test (SCT) in which the patient is asked to cancel a number of small targets (stars) spread over a page. This study will investigate whether an A4- or A3-size SCT is more sensitive for detecting visual neglect in patients who have had a stroke. In addition, this study will investigate whether the A4- or A3-size SCT is more efficient by measuring the time it takes for the patient to complete each of the A4- and A3-size tests. The results of this study will allow clinicians to adapt their screening method to ensure that it is as sensitive as possible for detecting visual neglect post-stroke. To take part in the study, a patient must have a known or suspected diagnosis of visual neglect post-stroke. The study will be conducted in an NHS hospital by Orthoptists working in stroke rehabilitation. Participants will undergo two additional assessments of their visual neglect, during which they will be required to complete the SCT once on A4-size paper and once on A3-size paper. It is anticipated that data collection will begin in November 2019 and participants will be in the study until August 2020.
