Official title: Engaging Mobile Prism Adaptation Treatment at Home

Interventions
- Behavioural therapy
Prism Adaptation - 15-degree prism goggles
Patients in the experimental condition will wear prism goggles while completing an iPad-administered aiming task. The prisms will shift the patients' vision 15 degrees rightward, causing a recalibration of visuo-motor information. Prism adaptation will be carried out for ten sessions for 15 minutes a day, over the span of two weeks.
- Other intervention
Prism Adaptation - 5-degree prism goggles
5-degree goggles are worn instead of the 15-degree prism goggles, while completing the same tasks as those assigned to the 15-degree condition.

About This Trial
Spatial neglect is a common disorder after stroke which leads to problems with noticing or responding to information from the left side of the body or space. This condition has been linked to reduced independence in a wide range of daily life activities including eating, dressing, and mobility. Despite its high prevalence in stroke patients, there is currently no standard of care for spatial neglect. Prism adaptation (PA) is a promising treatment, however, there are limitations to using PA in standard clinical care as it requires daily exposure for at least two weeks, yet access to equipment and supervision is limited. To solve this problem, the investigators have developed a new game-like PA treatment (Peg-the-Mole, PTM) that can be used at home without the need for daily in person therapist set-up and supervision. In this study the investigators aim to evaluate the feasibility and effectiveness of the gamified and portable PA procedure in an inpatient and home setting, with the hypothesis that the PA procedure will improve patient's neglect symptoms.
