In our aging world, the need to measure and evaluate motor and cognitive functions and to automate physical and occupational therapy will increase in the future. Many studies on VR-based rehabilitation systems are already underway. However, there are some issues such as the risk of falling or crashing due to the complete blockage of visual information, VR sickness, and lack of reality. The purpose of this research is to develop a system that simultaneously measures and evaluates multiple abilities and functions, such as motor function, cognitive function, and prediction ability, by using mixed reality (MR) smartglasses technology that enables interaction with spatially arranged objects while maintaining real-world information. In this study, we focused on the motor function of the upper limbs and cognitive function, and measured finger and gaze movements during a reaching task. In addition, we developed a game-based task for occupational therapy in a MR environment and reported the results.

Purpose: We aimed to verify the impact of functional remediation (FR) on serum brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB) levels, to explore the biomechanism of FR intervention in patients with euthymic bipolar disorder (BD).
Patients And Methods: This is a randomized controlled, 12-week intervention study with participants randomized into the FR group (n=39) and the treatment as usual group (TAU, n=42) at the 1∶1 ratio. 17-Hamilton Depression Rating Scale-17 (HDRS-17), Young Mania Rating Scale (YMRS), and Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) were used to assess affective symptoms and cognitive functioning both at baseline and week 12, respectively.

This mini-review examines the available papers about virtual reality (VR) as a tool for the diagnosis or therapy of neurodevelopmental disorders, focusing on Attention Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), and Specific Learning Disorders (SLD). Through a search on literature, we selected 62 studies published between 1998 and 2024. After exclusion criteria, our synoptic table includes 32 studies on ADHD (17 were on diagnostic evaluation and 15 were on therapeutic interventions), 2 on pure ASD, and 2 on pure SLD.

Executive dysfunction has been widely reported in children with autism spectrum disorder (ASD). Although studies have demonstrated the intervention effect of sports game and pretend play on children's executive function, few studies have examined the effect of Comprehensive games, and similar studies in children with ASD are scarce. In order to investigate the effect of different games on the executive functions of preschool children with ASD, 24 preschool children with ASD were selected in this study.
