Immersive Virtual Reality for the Cognitive Rehabilitation of Stroke Survivors

We present the results of a double-blind phase 2b randomized control trial that used a custom built virtual reality environment for the cognitive rehabilitation of stroke survivors. A stroke causes damage to the brain and problem solving, memory and task sequencing are commonly affected. The brain can recover to some extent, however, and stroke patients have to relearn how to carry out activities of daily living. We have created an application called VIRTUE to enable such activities to be practiced using immersive virtual reality. Gamification techniques enhance the motivation of patients such as by making the level of difficulty of a task increase over time. The design and implementation of VIRTUE is described together with the results of the trial conducted within the Stroke Unit of a large hospital. We report on the safety and acceptability of VIRTUE. We have also observed particular benefits of VR treatment for stroke survivors that experienced more severe cognitive impairment, and an encouraging reduction in time spent in the hospital for all patients that received the VR treatment.

Automated summary

This article presents the results of a double-blind phase 2b randomized control trial that utilized a custom built virtual reality environment for the cognitive rehabilitation of stroke survivors. The study introduces an application called VIRTUE, which enables stroke patients to practice daily activities using immersive virtual reality. The findings indicate particular benefits for stroke survivors with greater cognitive impairment and a positive reduction in hospital stay for all patients who received the VR treatment.
