Virtual Reality for the Rehabilitation of Acquired Cognitive Disorders: A Narrative Review

This review article explores the use of Virtual Reality (VR) technology in cognitive rehabilitation for individuals with neurological conditions, such as stroke, traumatic brain injury, and neurodegenerative diseases. The introduction highlights the challenges posed by cognitive impairments and the limitations of traditional rehabilitation methods. VR is presented as a transformative tool that immerses individuals in interactive environments, offering promising opportunities for enhancing cognitive functions and improving quality of life. This article covers the foundational principles of VR, its applications across different clinical conditions and cognitive domains, and evaluates empirical evidence supporting its efficacy. It also discusses the advantages, limitations, challenges, and ethical considerations in the use of VR for cognitive rehabilitation. This review concludes by exploring future developments, including advancements in VR technology, the integration of Augmented Reality (AR) and artificial intelligence (AI), and the importance of standardized assessment tools for the objective evaluation of rehabilitation outcomes.

A narrative review of the use of a cutting-edge virtual reality rehabilitation technology in neurological and neuropsychological rehabilitation

BACKGROUND

Virtual reality (VR) interventions have been increasingly used in the rehabilitation of a wide range of neurological and neuropsychological dysfunctions. Findings of previous reviews showed positive and promising effects of VR-based interventions. However, they summarized findings on VR-based intervention carried out through different VR systems and tasks.

OBJECTIVE

We carried out a narrative review with the aim of qualitatively synthesising the results of previous studies that used specific VR systems, i.e. the Khymeia -Virtual Reality Rehabilitation System, for treatment purposes.

METHODS

We searched the literature in various databases (i.e. EMBASE, Web of Science, SCOPUS, PubMed and PubMed Central) for studies published until November 23, 2023.

RESULTS

30 studies were selected. The VRRS was used for neuromotor rehabilitation only in 13 studies, for cognitive rehabilitation in 11 studies, and for both neuromotor and cognitive rehabilitation in six studies. The study design was heterogeneous including 15 randomised controlled trials.

CONCLUSION

After discussing each study according to the type of rehabilitation we concluded that the use and efficacy of VRRS rehabilitative intervention for increasing the neurological and neuropsychological functioning of patients are promising but more evidence is needed to make a comparison with conventional treatment. Future studies should also include long-term follow-up as well as cost-effectiveness analysis.
