Executive function (EF) and motor deficits have consistently been documented in studies of people with autism spectrum disorders (ASD). We investigated the effects of a pilot 30-session Makoto arena training intervention, a light and sound speed-based exergame, on response speed, EF, and motor skills in school-aged children with ASD. Strong correlations were seen between certain EF and motor scores, suggesting a relationship between the two constructs. Participants increased their average reaction speed (effect size = 1.18). Significant improvement was seen in the EF areas of working memory and metacognition and the motor area of strength and agility. Findings suggest that use of exergaming, specifically the Makoto arena, has the potential to be a valuable addition to standard intervention for children with ASD who have motor and EF impairments.

The purpose of this study was to examine the perceived preparedness of practitioners in the early identification of children ages birth to 6 yr with autism spectrum disorder (ASD). Both occupational therapists and occupational therapy assistants were included in this survey study. The online survey instrument consisted of 29 questions within six sections capturing participant demographics, delivery of occupational therapy services, action when autism is suspected, service delivery experience, resource sharing, and barriers to conducting autism screening. The results of the study provide baseline information concerning identified skills, practices, and barriers among 1,396 practitioners. Additionally, opportunities are revealed for professional development necessary to support practitioners in the early identification of children at risk for ASD through surveillance and screening among children ages birth to 6 yr.

A substantial body of evidence links differences in brain size to differences in brain organization. We have hypothesized that the developmental aspect of this relation plays a role in autism spectrum disorder (ASD), a neurodevelopmental disorder which involves abnormalities in brain growth. Children with ASD have abnormally large brains by the second year of life, and for several years thereafter their brain size can be multiple standard deviations above the norm. The greater conduction delays and cellular costs presumably associated with the longer long-distance connections in these larger brains is thought to influence developmental processes, giving rise to an altered brain organization with less communication between spatially distant regions. This has been supported by computational models and by findings linking greater intra-cranial volume, an index of maximum brain-size during development, to reduced inter-hemispheric connectivity in individuals with ASD. In this paper, we further assess this hypothesis via a whole-brain analysis of network efficiency. We utilize diffusion tractography to estimate the strength and length of the connections between all pairs of cortical regions. We compute the efficiency of communication between each network node and all others, and within local neighborhoods; we then assess the relation of these measures to intra-cranial volume, and the differences in these measures between adults with autism and typical controls. Intra-cranial volume is shown to be inversely related to efficiency for wide-spread regions of cortex. Moreover, the spatial patterns of reductions in efficiency in autism bear a striking resemblance to the regional relationships between efficiency and intra-cranial volume, particularly for local efficiency. The results thus provide further support for the hypothesized link between brain overgrowth in children with autism and the efficiency of the organization of the brain in adults with autism.

Many children within the autism population also have food selectivity, and it is not clear how this comorbid difficulty affects the mealtime experience for families. The purpose of this qualitative interview study was to gain an understanding of the mealtime experience of mothers of children with autism and food selectivity. The transcribed interviews were analyzed using a phenomenological approach. Mothers in this study described mealtime as difficult and stressful. Reasons for mealtime stress included the child’s self-restricted diet and difficulty sitting at the table. The mothers described attempts to improve mealtime but little success. Implications of the findings are discussed in the context of the literature.
