Official title
Accuracy and Utility of the Oxford Visual Perception Screening (OxVPS), a Screening for Visual Perception Difficulties in Stroke Survivors
Overview
The goal of this observational study is to learn how well the Oxford Visual Perception Screening (OxVPS) tool can identify stroke survivors with visual perception difficulties. The main aim is to determine the accuracy and utility of the OxVPS compared to the current gold standard assessment in stroke survivors. In other words, how well can the Oxford Visual Perception Screening tool (OxVPS) identify stroke patients with visual perception problems? Participants will completed the OxVPS and the current gold standards visual perception screening tool.
Detailed description
This is a non-experimental cross-sectional study. It aims to compare the new screening test OxVPS to the gold standard tests for visual perception difficulties.
Patients will be recruited at stroke rehabilitation units at hospitals in the North East of England and in Oxfordshire.
Following consent:
* Participants will complete the paper version of the Oxford Visual Perception Screen OxVPS (\~15 min). * Participants will complete screening for visual perception problems with a validated screening tool (\~30-120 min). * Participants will complete screening for cognition alterations and sensory vision with validated screening tools. (\~30 min) * Stroke details (time since stroke, severity) and demographic data (age, socio-economic status) will be collected to evaluated representativeness of the sample.
