What this trial studies

This project investigates the effects of prism adaptation as an early rehabilitation technique for treating unilateral spatial neglect in patients who have recently suffered a brain injury. Participants will be assigned to either an experimental group receiving prism treatment or a control group receiving neutral prisms, with both groups engaging in visuo-motor activities. The study will assess the effectiveness of the treatment through cognitive, functional, and motor-related measures, with follow-up evaluations conducted three months later. The goal is to improve long-term functional outcomes for patients affected by this cognitive disorder.

Who should consider this trial

Good fit: Ideal candidates are individuals experiencing their first neurological event, such as a stroke or brain tumor surgery, who exhibit signs of unilateral spatial neglect.

Not a fit: Patients with previous neurological disorders or cognitive deficits may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance rehabilitation outcomes for patients suffering from unilateral spatial neglect.

How similar studies have performed: While the use of prism adaptation is a novel approach in this specific context, similar interventions have shown promise in other studies addressing spatial neglect.
