The Neural Circuitry Of Sensory Processing In Post-Traumatic Stress Disorder, Sherain Harricharan

Electronic Thesis and Dissertation Repository

Background: Traumatic experiences can have severe emotional and psychological consequences, which may affect the capacity to process both internal and external sensory information. Such aberrations may have cascading effects in individuals with post-traumatic stress disorder (PTSD), where alterations in sensory processing may hinder the capacity for higher-order executive functions, including emotion regulation. Delineating the neural circuitry of subcortical and cortical structures thought to be central to sensory processing is therefore critical to the study of PTSD and may help to develop an understanding of the neurobiological mechanisms underlying this often debilitating disorder.

Methods: Various neuroimaging approaches were employed to investigate …

Use Of The Star Process For Children With Sensory Processing Challenges, Sarah A. Schoen, Lucy Jane Miller, Stephen Camarata, Andrea Valdez

The Open Journal of Occupational Therapy

Background: This study examined the effectiveness of the STAR PROCESS, an intensive, short-term intervention that combines principles of sensory integration, relationship-based therapy, and parental-therapist collaboration for children with sensory processing challenges.

Method: A nonconcurrent multiple baseline, repeated measures design was used. Four boys, aged 5 years 0 months to 7 years 9 months, participated in this study. The mean length of intervention was 22 sessions delivered 3 to 5 times per week. A behavioral coding system was used to measure change in four areas: play level, positive affect, joint attention, and novel use of equipment. The theory of …

Neural Foundations Of Ayres Sensory Integration, Shelly J. Lane, Zoe Mailloux, Sarah Schoen, Anita Bundy, Teresa A. May-Benson, L. Diane Parham, Susanne Smith Roley, Roseann C. Schaaf

Department of Occupational Therapy Faculty Papers

Sensory integration, now trademarked as Ayres Sensory Integration^® or ASI, is based on principles of neuroscience and provides a framework for understanding the contributions of the sensory and motor foundations of human behavior. The theory and practice of ASI continues to evolve as greater understanding of the neurobiology of human behavior emerges. In this paper we examine core constructs of ASI identified in the seminal work of Dr. Jean Ayres, and present current neuroscience research that underlies the main patterns of sensory integration function and dysfunction. We consider how current research verifies and clarifies Ayres’ propositions by describing functions …

The Sensory Processing 3-Dimensions Scale: Initial Studies Of Reliability And Item Analyses, Shelley Mulligan, Sarah A. Schoen, Lucy Jane Miller, Andrea Valdez, Deborah Magalhaes

The Open Journal of Occupational Therapy

Background: The Sensory Processing 3-Dimensions Scale (SP-3D) is a performance-based measure for assessing sensory processing abilities and challenges, including sensory modulation, sensory discrimination, and sensory-based motor disorders. Initial studies of reliability were conducted, and item response theory was applied to assist in refining the measure.

Methods: Descriptive and correlational methods were used to examine internal consistency of the scales and inter-rater reliability. Item response theory using Rasch analyses was applied to examine unidimensionality of scales, model fit, and item difficulty.

Results: Internal consistency for most measures was acceptable, demonstrating the subtests, domains, and behavior scales as distinct …

Use Of The Alert Program® In A Sensory Room At An Emergency Children's Shelter, Sarah May Bautista

OT Student Capstones

Children who have experienced trauma have difficulty with behavioral self-regulation which effects social participation, play, and academics (Petrenchik & Weiss, 2015). Young children learn through exploration of their environment and gather information from the senses of taste, sight, touch, smell, sound, proprioception, and body movement (vestibular). As sensory information is gathered, the brain and body organize and interpret these sensations. The manner in which these senses are experienced determine which sensory experiences are preferred, and the nature of behavioral reactions. Children who have experienced trauma have difficulty managing stress, emotions, and daily routines. In the community occupational therapists can encourage …

Effects Of A Sensory Diet On Attention And Participation In Children With Autism, Leighanne Smith-Mrkaja

Theses and Dissertations

This applied dissertation was designed to provide initial knowledge regarding sensory diets and sensory-based interventions. The need for classroom-based sensory interventions are not always considered, especially with the high number of students diagnosed with ASD at the researcher’s school. Often sensory intervention may not be considered educationally relevant, especially in the prekindergarten level. With the proper training and materials, as well as the guidance of the school-based occupational therapist, teachers, other therapists, classroom assistants, parents, and school-based staff might be able to utilize sensory-based activities like sensory diets to increase participation, positive behaviors, and attention. The following applied research study …
