Virtual Reality Technology in Cognitive Rehabilitation Application: A Bibliometric Analysis
ABSTRACT
Background:
In recent year, with the development of computer science and medical science, virtual reality (VR) technology has been regarded as a promising tool to improve cognitive function. Research on VR-based cognitive training has gained more and more attention.
Objective:
This study aimed to investigate the application status, research hotspots, and emerging trends of VR in cognitive rehabilitation in the past 20 years.
Methods:
Articles on the application of VR in cognitive rehabilitation from 2001 to 2021 were retrieved from the Web of Science Core Collection. CiteSpace software was used for visual analysis of authors and countries/regions, and Scimago Graphica software was used for the geographic visualization of published countries/regions. Keywords were clustered by gCLUTO software.
Results:
A total of 1,259 papers were included. In recent years, research on the application of VR in cognitive rehabilitation has been continuously hot, and the annual publication of relevant literature has shown a positive trend. The United States ranked first with 328 papers, and Italy ranked second with 140 papers. Giuseppe Riva, an Italian academic, was the most prolific author with 29 publications. The most frequently cited reference was Using Virtual Reality to Characterize Episodic Memory Profiles in Amnestic Mild Cognitive Impairment and Alzheimer's Disease: Influence of Active and Passive Encoding. The most common keywords used by researchers include virtual reality, cognition, rehabilitation, performance, and older adult. The largest amount of research was funded by the European Commission.
Conclusions:
The studies on the application of VR in cognitive rehabilitation have maintained an increasing trend, with research hotspots focusing on stroke, Alzheimer's disease, attention deficit hyperactivity disorder, and post-traumatic stress disorder. The cooperation among authors and countries has been carried out to a certain extent. Remote rehabilitation based on VR will likely become the focus of future research. To achieve the wide application of virtual reality technology, we should pay attention to the requirements of patients, strengthen multidisciplinary cooperation, increase the fund investment, perfect the incentive mechanism.
