Exploring the reliability and sensitivity of the EEG power spectrum as a biomarker.

Introduction: The slope of the electroencephalography (EEG) power spectrum (also referred to as 1/f noise) is an important consideration when calculating narrow-band power. However, psychophysiological data also suggest this slope is a meaningful signal itself, not merely background activity or noise. We present two different methods for quantifying the slope of the power spectrum and assess their reliability and sensitivity.

Power-Up: Exploration and Play in a Novel Modified Ride-On Car for Standing.

Purpose: The purpose of this study was to compare the physical activity and play behaviors of preschoolers without disabilities and 1 preschooler with physical disability.

Methods: Participants were 42 preschoolers without disabilities and 1 preschooler with physical disability (Child A). Child A used either crutches or a modified ride-on car while in the gymnasium and playground.

Why We Move: Social Mobility Behaviors of Non-Disabled and Disabled Children across Childcare Contexts.

Background: Social mobility is defined as the co-occurrence of self-directed locomotion and direct peer interaction. Social mobility is a product of dynamic child-environment interactions and thus likely to vary across contexts (e.g.

Real-World Performance: Physical Activity, Play, and Object-Related Behaviors of Toddlers With and Without Disabilities.

Purpose: To describe and compare the occurrence and co-occurrence of physical activity (PA), play, and object-related behaviors in toddlers with and without disabilities.

Methods: Participants included 23 toddlers (21 with typical development (TD) and 2 with disabilities). Direct observation was used to describe the type and level of PA, play interactions, and object-related behaviors through video recordings.
