The purposes of this paper are to provide an overview of the state of the science of sleep in children with autism spectrum disorder (ASD), present hypotheses for the high prevalence of insomnia in children with ASD, and present a practice pathway for promoting optimal sleep. Approximately two thirds of children with ASD have chronic insomnia, and to date, the strongest evidence on promoting sleep is for sleep education, environmental changes, behavioral interventions, and exogenous melatonin. The Sleep Committee of the Autism Treatment Network (ATN) developed a practice pathway, based on expert consensus, to capture best practices for screening, identification, and treatment for sleep problems in ASD in 2012. An exemplar case is presented to integrate key constructs of the practice pathway and address arousal and sensory dysregulation in a child with ASD and anxiety disorder. This paper concludes with next steps for dissemination of the practice pathway and future directions for research of sleep problems in ASD.

BACKGROUND AND PURPOSE: DTI data of the normal healthy spinal cord in children are limited compared with adults and are typically focused on the cervical spinal cord. The purpose of this study was the following: to investigate the feasibility of obtaining repeatable DTI parameters along the entire cervical and thoracic spinal cord as a function of age in typically developing pediatric subjects; to analyze the DTI parameters among different transverse levels of the cervical and thoracic spinal cord; and to examine the sex differences in DTI parameters along the cervical and thoracic spinal cord.

Magnetic resonance based diffusion imaging has been gaining more utility and clinical relevance over the past decade. Using conventional echo planar techniques, it is possible to acquire and characterize water diffusion within the central nervous system (CNS); namely in the form of Diffusion Weighted Imaging (DWI) and Diffusion Tensor Imaging (DTI). While each modality provides valuable clinical information in terms of the presence of diffusion and its directionality, both techniques are limited to assuming an ideal Gaussian distribution for water displacement with no intermolecular interactions. This assumption neglects pathological processes that are not Gaussian therefore reducing the amount of potentially clinically relevant information. Additions to the Gaussian distribution measured by the excess kurtosis, or peakedness, of the probabilistic model provide a better understanding of the underlying cellular structure. The objective of this work is to provide mathematical and experimental evidence that Diffusion Kurtosis Imaging (DKI) can offer additional information about the micromolecular environment of the pediatric spinal cord. This is accomplished by a more thorough characterization of the nature of random water displacement within the cord. A novel DKI imaging sequence based on a tilted 2D spatially selective radio frequency pulse providing reduced field of view (FOV) imaging was developed, implemented, and optimized on a 3 Tesla MRI scanner, and tested on pediatric subjects (healthy subjects: 15; patients with spinal cord injury (SCI):5). Software was developed and validated for post processing of the DKI images and estimation of the tensor parameters. The results show statistically significant differences in mean kurtosis (p < 0.01) and radial kurtosis (p < 0.01) between healthy subjects and subjects with SCI. DKI provides incremental and novel information over conventional diffusion acquisitions when coupled with higher order estimation algorithms.

Study design: The items and response scales of the Spinal Cord Independence Measure (SCIM-III) self report (SR) were exposed to formal cognitive testing with children with SCI, and in parallel a survey using the modified Delphi Technique was conducted to engage content experts in an iterative critical review of the SCIM-III SR. Objectives: To evaluate the validity of the SCIM-III SR for pediatric utilization. Setting: United States of America. Methods: Formal cognitive testing was conducted with 17 youths with SCI and required them to read and answer each SCIM-III SR item aloud. Think aloud methodology was used to record details about how youths understood and interpreted items and why they selected a given response. The interviews were audiotaped and transcribed verbatim. Content analysis focused on identifying words that children could not read or understand. In parallel, the Modified Delphi Technique engaged expert therapists to critically review the SCIM-III SR for pediatric utilization. Results: Every SCIM-III SR item and response scale required modification before children were able to read, understand and respond to them. Youth encountered difficulties because of vague terms, medical jargon and complex words and phrases. Three iterative Delphi rounds were required before achieving 80% agreement that items and response scales were written well for children. Conclusion: Our findings informed modifications to every SCIM-III SR item and response scale, producing a pediatric version of the tool that we formally refer to as the SCIM-III SR-Youth (SCIM-III SR-Y).

The Capabilities of Upper Extremity Test (CUE-T) and the Graded Redefined Assessment of Strength, Sensibility and Prehension (GRASSP) were both developed to detect change in upper extremity (UE) function in persons with tetraplegia. To compare the responsiveness and minimal clinically important difference (MCID) of the CUE-T and the quantitative prehension (QtP) scale of the GRASSP. Subjects included 69 persons with tetraplegia: 60 with acute and 9 with chronic injuries. Subjects were assessed twice 3 months apart using the CUE-T, QtP-GRASSP, and upper extremity motor scores (UEMS). Subjects rated their impression of change in overall and right/left UE function from -7 to +7. The standardized response mean (SRM) was determined for acute subjects. MCID was estimated using a small subjective change (2-3 points) and change in UEMS. Subjects were 41.9 ± 18.1 years old, neurological levels C1-C7; 25 were motor complete. For acute subjects, the SRMs for total/side CUE-T scores were 1.07/0.96, and for the QtP-GRASSP they were 0.88/0.78. MCIDs based on subjective change for total/side CUE-T scores were 11.7/6.1 points and for QtP-GRASSP were 6.4/3.0 points. Based on change in UEMS, MCIDs for total/side were 11.9/6.3 points for CUE-T and 6.0/3.3 points for QtP-GRASSP. Some subjects had changes in the CUE-T due to its arm items that were not seen with the QtP-GRASSP. Both the CUE-T and QtP-GRASSP are responsive to change in persons with acute cervical spinal cord injury with large SRMs. The CUE-T detects some changes in UE function not seen with the QtP-GRASSP.

Background: Minimal attention has been given to the perspectives and experiences of individuals post incarceration regarding stigma and its impact on reintegration and occupational engagement. This research aimed to understand how stigma is experienced among individuals who were formerly incarcerated and its influence on occupational engagement, specifically social participation, work, and school occupations. This research also examined the role of occupational therapy as an intervention in addressing stigma from the perspectives of individuals who were formerly incarcerated to inform practice and mitigate the influence of stigma. Method: Interviews were conducted with 10 participants of a work rehabilitation program for people who had previously been incarcerated. A thematic analysis was performed to identify major themes. Themes were organized into concept maps related to stigma as experienced by those who were formerly incarcerated. Results: Four overarching themes emerged. These themes, internal and external perceptions, and family and community systems, served to enable as well as disable the impact of stigma on daily life post incarceration. Conclusion: The themes presented increased the understanding of stigma as experienced by individuals who were formerly incarcerated and supported the need for further research and occupational therapy programming specifically aimed at minimizing the impact of stigma. Comments This study was approved by the university's institutional review board and completed in partial fulfillment of the university's occupational therapy postprofessional doctorate program. No conflicts of interest are declared.

Date Presented 4/8/2016 The experiences of ex-offenders regarding stigma and its effect on reintegration and occupational engagement were explored. Results inform occupational therapy’s understanding of stigma and areas to further explore for future program development and research aimed at minimizing stigma and facilitating reintegration.
