Feasibility of a developed cognitive training system based on virtual reality with smart mirror for expert in community older cognitive disabled persons setting.

Abstract

BackgroundNumerous stroke survivors reintegrating into the community experience cognitive challenges that restrict their engagement, subsequently contributing to additional cognitive decline and adversely affecting their quality of life.ObjectiveThis study seeks to feasibility a cognitive training system based on virtual reality with a smart mirror designed for cognitive disabled persons with chronic stroke in the community setting.MethodsTen cognitive disabled persons with chronic stroke aged 60 years older, each with independent mobility in the community, were involved in this study. The validation process included a 30-min cognitive training session administered twice a week for eight weeks. The feasibility of cognitive function assessments employed the MoCA-K and CoSAS. Additionally, a usability test was performed at the end of the experiment using SUS and the Adapted IMI. The Wilcoxon signed rank test was then employed to compare pre- and post-cognitive function results.ResultsThe feasibility of the implemented cognitive training system based on virtual reality with smart mirror revealed significant differences in the total score, delayed recall, and orientation items of the MoCA-K (p < 0.05). Additionally, a notable improvement was observed in the accuracy and response time of task performance in the CoSAS (p < 0.05). Usability test results indicated an SUS mean score of 73.5 (SD 17.25) and an Adapted IMI score of 5.63 (SD 1.55), surpassing suggested thresholds for usability tests.ConclusionsProviding a cognitive training system tailored for the community, this approach aims to the prevention and recovery of cognitive issues in the older cognitive disabled persons with chronic stroke.
