Purpose: Develop and pilot an iPad-based intervention for improving visual-motor coordination, visual-spatial processing/reasoning, and visual attention in children with surgically treated hydrocephalus (HCP).
Methods: We developed an intervention protocol targeting visual-motor coordination, visual-spatial processing/reasoning, and visual attention. Fourteen participants with HCP completed 30 h of training over 6 weeks. The primary outcome measure was the Perceptual Reasoning Index from the Wechsler Abbreviated Scale of Intelligence, Second Edition. Secondary measures included subtests from the Wechsler Intelligence Scale for Children, Fourth Edition, Developmental NEuroPSYchological Assessment, Second Edition (NEPSY-II), and Purdue Pegboard.
Results: Children with HCP demonstrated gains with statistical significance on the Perceptual Reasoning Index. We also observed significant improvement on a timed test of visuo-motor coordination (Wechsler Intelligence Scale for Children, Fourth Edition, Coding).
Conclusion: Our iPad-application-based intervention may promote visual-motor coordination, visual-spatial processing/reasoning, and visual attention skills in children with HCP, offering an engaging and economical supplement to more conventional therapies.

Objective: The purpose of this study was to quantitatively measure the split-step skills of the world's top badminton players to clarify the characteristics underlying these skills when moving into the forehand position in the rear court.
Methods: We analyzed the four best ranking players (1st to 4th) in the men's singles competition at the World Badminton Federation (BWF) World Championships 2023, a world tournament whose match videos are available online. Analysis 1 was conducted to determine the location of the players' feet on the court when performing a split-step while moving to the forehand rear court, as well as the width of the stance and the reaction time from that stance to taking the first step.

We propose a novel approach to investigate the brain mechanisms that support coordination of behavior between individuals. Brain states in single individuals defined by the patterns of functional connectivity between brain regions are used to create joint symbolic representations of brain states in two or more individuals to investigate symbolic dynamics that are related to interactive behaviors. We apply this approach to electroencephalographic data from pairs of subjects engaged in two different modes of finger-tapping coordination tasks (synchronization and syncopation) under different interaction conditions (uncoupled, leader-follower, and mutual) to explore the neural mechanisms of multi-person motor coordination.

Background: Recent studies have shown that the Rey Complex Figure Test (RCFT) is useful for early detection of Alzheimer's disease (AD). While RCFT is known as a test for visuoconstruction and memory, it demands executive components during copying and recalling of the complex figure. This study aims to explore which features of executive function are involved in RCFT performance and which of them are clinically significant indicators in older adults.

Background: Unsupervised high-frequency cognitive-ecological momentary assessment (EMA) on smartphones is increasingly used to assess preclinical risk for Alzheimer's disease and related dementias (ADRD). While these tests are reliable and valid for individuals with preclinical ADRD, it is unclear whether administering cognitive EMAs to people living with ADRD is feasible and valid. Our study explored the feasibility and validity on cognitive EMA tests in people living with moderate to severe ADRD.

Background: Individuals with Down syndrome (DS) typically develop Alzheimer's disease (AD) at an early age. Estimates of the age of decline vary, but typically place it in the early-mid 50s. As AD onset can be difficult to identify in intellectually impaired cohorts, understanding the expected timing of decline may help individuals and caregivers prepare.
