Assessment for unilateral spatial neglect using eye-tracking glasses

Unilateral spatial neglect (USN) is an impaired ability to respond to sensory stimuli within the environment on the contralateral side of brain lesion location resulting from stroke. Currently USN is most commonly assessed using standard pen-and-paper tasks such as cancellations tasks, figure copying and line bisection. Despite these assessments being widely used, results have been found to often be inconsistent in detection of USN. This trial uses Tobii Pro eye-tracking glasses in the observation of inpatients with and without USN in a 10-15 minute functional task (making a hot beverage). The glasses record where the participant is looking, what they see and the patterns of their eye-tracking during the task. This will be a single 10-15 session wearing the glasses whilst making a hot beverage in a standardised therapy kitchen in a rehabilitation hospital. Additionally pen and paper tests of USN will be completed by all participants and will take a further 10-15 minutes.
