Facilitating Inclusion for Neurodiverse Students Using Evidence-Based Practices: A Strengths-Based Approach to Sensory Regulation

ABSTRACT Educational inclusion aims to support all students through instructional and contextual designs that promote learning. Educators are assigned the task of teaching an increasingly neurodiverse population with varying neurological processes and perceptions. Traditional school-based settings are designed for individuals with less neurodivergence, and, therefore, may not adequately facilitate an environment supportive of learning for all students. Additionally, neurodiverse learners, including those with autism, may have sensory processing differences that impact occupational participation and performance. Understanding the processing differences of neurodivergent students and interventions that support those needs may facilitate successful inclusion programs. Research and data analysis confirmed the Ready to Learn and Play (RtLP) as an evidence-based framework to facilitate participation and performance for individuals with neurodiversity and sensory processing challenges, both for in-person (statistical significance p = .001) and virtual presentation of the RtLP content (statistical significance p = .00000607). Through a neuroaffirming approach to teaching, coaching, and training, RtLP may assist in supporting individuals with sensory regulation challenges to participate to the greatest extent possible in inclusive education.

Characteristics of Adults With Sensory Differences: An Exploratory Study Using the Multidimensional Assessment of Interoceptive Awareness, Version 2

Interoception was explored in adults with sensory integration and processing differences Retrospective data were collected from 57 adults. Data included presenting problems, diagnoses, and self-report using the Multidimensional Assessment of Interoceptive Awareness, Version-2 (MAIA-2). Frequencies were computed. Data from the MAIA-2 were described and correlated. One hundred percent of the sample had interoceptive difference from norms. Common presenting problems were emotional regulation, social relationships, activities of daily living, and mental functions. Commonly reported diagnoses were anxiety and depression. This study highlights the importance of interoception and the usefulness of the MAIA-2.

Relaxed performances: supporting aural diversity and neurodiversity among classical concert audiences in the United Kingdom

ABSTRACT Current discourse at the intersection between sound studies and disability studies has highlighted the phonocentric nature of conventional understandings of listening – especially in relation to engagement with classical music performance. The perpetuation of ableist notions of “normal” and “expert” listening risk overlooking multimodal and embodied listening practices of the kind advocated by aurally-diverse and neurodiverse concert audiences. In this article, we evaluate the extent to which Relaxed Performances (RPs) may offer opportunities for such diverse ways of listening, through surveying the existing provision of RPs in the United Kingdom and reviewing three examples of performances by the Graeæ Theatre Company, the English National Opera, and the BBC Proms. We conclude that further work needs to be undertaken for emergent RP practices to be codified and become widespread, but highlight the importance of this work in making classical music performance more accessible and beneficial for people who experience differences in sensory processing.

A Pilot Study Exploring Caregivers' Experiences Related to the Use of a Smart Toothbrush by Children with Autism Spectrum Disorder.

Research on caregivers for children with intellectual disabilities, particularly those with autism spectrum disorder (ASD), has highlighted several obstacles to achieving better oral health. These include challenges with tolerating oral care, sensory processing differences, uncooperative behaviors, and communication impairments. There is limited understanding of what caregivers would consider "successful assistance" in improving oral health for these children. This pilot study aimed to examine caregivers' and user's experiences with a Kids Smart Electric Toothbrush used by children with ASD. It involved open-ended interviews and questionnaires with caregivers prior to utilization of the toothbrush and after 4 weeks of product use by the child. Seventeen children with ASD, aged 5-12, participated. A total of 58.8% of caregivers said their child brushed more often, and all reported brushing at least twice a day by week 4. Caregivers reported that children became more independent while brushing their teeth and achieved better quality brushing. Caregivers' frustration with the brushing process, satisfaction with the device, and need to assist the child with brushing were improved. Caregivers did encounter some technical difficulties with the app. This study will assist in exploring "smart" toothbrush technologies for oral hygiene in children with ASD.

Mothers' Perspectives: Daily Life When Your Child Has Sensory Differences.

A child's sensory processing and sensory integration (SP-SI) differences can be a barrier to participation in daily life for both child and mother. Supporting mothers is advocated for, but little is known about the everyday experiences of these mothers. To gain an understanding of daily life for mothers and their children with SP-SI differences. Qualitative semi-structured interviews with six mothers were analyzed through thematic analysis. Theme 1 described the impact of child SP-SI on daily life, including challenges in occupations across environments, adaptations required, and the lack of knowledge and understanding from social and professional networks. Theme 2 identified what helps: empowering mothers through relationships based on listening, gaining knowledge, and understanding, and adapting the activity and the environment. Mothers report that their child's SP-SI differences impact daily occupations and social relationships. In addition, supportive relationships, adapting activities, and adapting the environment, support participation.

Broad autism phenotype traits and self-reported sensory processing across sensory modalities

BackgroundDespite a longstanding connection between sensory processing and autism, sensory processing differences did not become part of the diagnostic criteria for autism spectrum disorder (ASD) until the DSM-5. Emerging research suggests that differences in sensory processing may be related to broad autism phenotype traits in the general population. The present study adds to this literature by including a more comprehensive analysis of sensory modality and a measure of sensory gating that has not previously been related to ASD traits. MethodThrough Qualtrics, 152 participants met inclusion for the study and completed the Broad Autism Phenotype Questionnaire (BAPQ), Autism Spectrum Quotient (AQ), and several sensory questionnaires. ResultsAs predicted, ASD traits were significantly related to all sensory questionnaires, suggesting that as ASD traits increased, sensory reactivity differences increased. Similarly, participants who scored over established cut-offs on the AQ and BAPQ endorsed a significantly higher number of sensory difficulties. Interestingly, some, but not all, sensory modalities, measured by the Adult Sensory Processing Scale (ASPS), predicted scores on the AQ and BAPQ. ConclusionsThese findings provide additional support for sensory processing being included in the broad autism phenotype and suggest that sensory processing may have consequential impacts, in both ASD and individuals without a diagnosis.

Neurophysiological and Clinical Outcomes in Episodic Migraine Without Aura: A Cross-Sectional Study.

The aim of this study was to assess differences between people with episodic migraine and healthy controls in some neurophysiological and clinical outcomes, which, in turn, may highlight the differences in sensory processing, especially in cortical excitability, pain processing, and executive function. A cross-sectional study was performed, including the following outcomes: pressure pain thresholds with algometry; resting motor threshold, short-interval intracortical inhibition, and intracortical facilitation with transcranial magnetic stimulation; and executive functions with the trail making test and the frontal assessment battery. Thirty adults with migraine (36 ± 10 years) and 30 healthy controls (29 ± 14 years) were included in this study. Compared with the healthy controls, participants with migraine presented lower pressure pain thresholds values in all the assessed muscles ( P < 0.001), lower resting motor threshold (-10.5% of the stimulator output, 95% CI: -16.8 to -4.2, P = 0.001, Cohen d = 0.869) and higher short-interval intracortical inhibition motor-evoked potential's amplitude at 3 ms (0.25, 95% CI: 0.05 to 0.46, P = 0.015, Cohen d = 0.662), and worse performances both in trail making test (7.1, 95% CI: 0.9 to 13.4, P = 0.027, Cohen d = 0.594) and frontal assessment battery (-1.1, 95% CI: -1.7 to -0.5, P = 0.001, Cohen d = 0.915). Participants with migraine presented significant differences in cortical excitability, executive functions, and pressure pain thresholds, compared with healthy controls.

AGEING WELL WITH AUTISM

Abstract Autism is characterized by patterns of neurological development that can cause differences in social interactions and sensory processing; restricted and repetitive patterns of behavior; and difficulties in identifying and describing feelings. The highly sociable and unpredictable environments typical of most societies are poorly suited to autistic people*, leading to disadvantage and exclusion. Despite increasing numbers of people aging with autism, little is known about the needs and experiences of middle-aged and older autistic adults. This is important given that autistic people experience higher rates of health and functional difficulties, and express a need for appropriate, accessible forms of support as they age. In this study, we interviewed seventeen autistic adults, aged from 46-72 years, about their views and experiences of aging, and how services could better support them to age well. The transcribed interviews were analyzed using inductive thematic analysis. The findings revealed several potential ways that autism affected people’s ability to age well. This included difficulties in accessing formal and informal supports; interactions between autism and health conditions; and negative attitudes and low understanding about autism encountered within services and society. Recommendations for supporting autistic adults to age well included involving autistic people in the design of services, and introducing specialized advocate/coordinator roles or ‘one-stop-shop’ hubs that could help autistic people navigate services more easily. * Our use of the terms ‘autistic people/adults’ is in-line with evidence-based guidance for writing about autism research, and is preferred by autistic people to ‘person-first’ terms like ‘person with autism’ (https://journals.sagepub.com/pb-assets/cmscontent/AUT/Autism-terminology-guidance-2021-1626860796.pdf)

Effects of Increased Temperature on Brain and Sensory Development in the Port Jackson Shark (Heterodontus portusjacksoni)

Morphological differences in the peripheral (sensory) and central (brain) nervous system may confer sensory and/or behavioral variation in elasmobranchs, both across taxa and throughout ontogeny. Over the last century, sea surface temperatures have increased over 0.5 °C and are predicted to rise 1–4 °C by the year 2100, potentially affecting species’ physiological performance negatively. As the nervous system of fishes grows continually throughout their lives, it may be highly plastic in response to environmental changes. This study examined the effects of increased rearing temperature on nervous system development in Port Jackson sharks (Heterodontus portusjacksoni). Egg cases (n = 21) were collected from Gulf St. Vincent (Adelaide, SA) and placed into either ambient (17.6 °C) or 3 °C above ambient seawater conditions through hatching and reared for up to five months post-hatch. Relative volumes of the eyes and nose (olfactory rosette) were quantified using magnetic resonance imaging, and relative brain size and size of major brain regions were compared between the two treatment groups. The size of the olfactory bulbs and tegmentum varied significantly between the treatment groups, which suggest differences in primary, secondary, or tertiary sensory processing and/or motor functions at elevated temperatures. While studies on acute responses to environmental conditions cannot inform true adaptation across broad timescales, understanding the effects of increased temperature on the brain phenotype can aid in predicting how elasmobranchs may fare in response to changing ocean conditions.

Alexithymia in Adult Autism Clinic Service-Users: Relationships with Sensory Processing Differences and Mental Health.

Mental health difficulties commonly co-occur with autism, especially in autistic people accessing clinic services, impacting substantially on quality-of-life. Alexithymia (difficulty describing/identifying feelings) and sensory processing differences are prevalent traits in autism that have been associated with depression/anxiety in autistic community samples. However, it is important to better understand interrelationships between these traits in clinical populations to improve identification of service-user needs. In this study, 190 autistic adults (65.3% male), seen in a tertiary autism clinic, completed self-report measures of alexithymia (20-item Toronto Alexithymia Scale), sensory processing differences (Adolescent/Adult Sensory Profile) and depression/anxiety (Hospital Anxiety and Depression Scale). Multiple linear regression models and mediation analyses were used to examine associations between alexithymia, sensory processing differences, and depression/anxiety severity. Across the sample, 66.3% of individuals (N = 126) were classified as alexithymic (score ≥ 61). Total alexithymia and difficulty describing/identifying feelings were significantly associated with depression severity (β = 0.30-0.38, highest p < 0.002), and difficulty identifying feelings was significantly associated with anxiety severity (β = 0.36, p < 0.001). Sensory processing differences were also significantly associated with depression severity (β = 0.29, p = 0.002) and anxiety severity across all models (β = 0.34-0.48, highest p < 0.001) Finally, difficulty describing/identifying feelings partially mediated the relationships between sensory processing differences and both depression/anxiety severity. Overall, these results highlight that interventions adapted for and targeting emotional awareness and sensory-related uncertainty may improve mental health outcomes in autistic service-users.

Sensory Processing Preferences in an Adult Acute Mental Health Setting: A Retrospective Study.

Sensory processing patterns may inform mental health diagnosis-specific treatment plans. To compare sensory processing preferences of patients admitted with depression and substance use disorder diagnoses. Retrospective cohort study. Acute inpatient mental health center. Patients ages 18 to 64 yr with a primary diagnosis of depression or substance use disorder who completed the Adolescent/Adult Sensory Profile (AASP). Comparison of AASP quadrant scores between subgroups. Participants (n = 211; M age = 33.8 yr) had a primary diagnosis of depression (n = 121; 57%) or substance use disorder (n = 90; 43%). The depression and substance use disorder groups yielded the following AASP quadrant scores, respectively: low registration, Ms = 38.2 and 34.3 (SDs = 9.4 and 8.0), p = .002; sensation seeking, Ms = 46.8 and 50.6 (SDs = 8.1 and 9.1), p = .002; sensory sensitivity, Ms = 43.4 and 39.8 (SDs = 10.3 and 9.9), p = .013; and sensation avoiding, Ms = 45.6 and 40.1 (SDs = 9.5 and 10.3), p < .001. These differences persisted when scores were normalized against standard population scores. The majority with a primary diagnosis of depression ranked "more/much more than most" for low registration (69; 57.0%), sensory sensitivity (61; 50.4%), and sensation avoiding (79; 65.3%). Those with a primary diagnosis of SUD ranked most frequently as "similar to most" in all quadrants. Sensory processing preferences differ by primary mental health diagnosis and may provide insight into treatment planning. What This Article Adds: This study identifies differences in sensory processing between patients with a primary diagnosis of depression and those with a primary diagnosis of substance use disorder, suggesting that clinical interventions should account for sensory preferences. Providing appropriate sensory experiences (sensory room, sensory boxes, etc.) may allow patients to function at an optimal level by improving their ability to self-regulate emotions and behaviors.

Sensory Processing Differences in Individuals With Autism Spectrum Disorder: A Narrative Review of Underlying Mechanisms and Sensory-Based Interventions.

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with social interaction and restricted, repetitive patterns of behavior. Altered sensory processing and perception are consideredcharacteristics of ASD. Sensory processing differences (SPDs) are commonly observed in individuals with ASD, leading to atypical responses to sensory stimuli.SPDs refer to the way in which individuals receive, process, and respond to sensory information from the environment. People with SPDs may be hypersensitive (over-reactive) or hyposensitive (under-reactive) to sensory input, or they may experience fragmented or distorted perceptions. These differences can make it difficult for individuals with SPDs to filter out irrelevant sensory information, and to integrate sensory information from different sources. This study intends to investigate the underlying mechanisms contributing to SPDs in individuals with autism and determine the effectiveness of sensory-based therapies in addressing these challenges. The literature suggests that altered neural pathways, sensory gating dysfunction, and atypical sensory modulation contribute to SPDs in individuals with ASD. Assistive technology, environmental changes, and sensory-based interventions like sensory integration therapy (SIT) have all shown promise in improving sensory functioning and reducing associated behavioral issues. However, further research is needed to improve our understanding of sensory processing in autism and to optimize interventions for individuals with ASD.

Sensory processing, emotional and behavioural challenges in children with autism spectrum disorder and attention deficit hyperactive disorder

Background Previous studies have found sensory processing abnormalities, behavioural, and emotional challenges in children with developmental disorders, particularly autism spectrum disorder (ASD) and attention deficit hyperactivity disorder. There is little research on the sensory, emotional, and behavioural differences between individuals with autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD) across age cohorts. Aim This study examined the correlation and differences in sensory processing, emotional, and behavioural challenges in children with autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), and typically developing children. This study also examined these characteristics in two age groups: 4–11-year-olds and 12–18-year-olds. Methodology The study included 362 mothers of their children among three groups: 123 with ASD, 100 with ADHD, and 139 from the typical population. The Short Sensory Profile (SSP) and Child Behaviour Checklist were administered to participants along with a demographic profile. The participants were between 25–50. Pearson correlation, MANOVA and MANCOVA were used to fulfil research objectives. Results and discussion The study found a link between tactile sensitivity, sensation seeking, auditory filtering, and behavioural and emotional issues in children with ASD and ADHD. Sensory features also predicted emotional and behavioural issues in these populations. The MANCOVA analysis showed significant variations in sensory processing, behavioural, and emotional issues among populations, controlling for age groups. Conclusion In conclusion, this study shows the need for early diagnosis of sensory processing impairments in these groups and developmental-stage-specific therapies. The study highlights the need for longitudinal research to understand sensory processing patterns, emotional, and behavioural issues, and development, particularly in India.

Differentiation of workers into soldiers is associated with a size reduction of higher-order brain centers in the neotropical termite Procornitermes araujoi

Comparing the size of functionally distinct brain regions across individuals with remarkable differences in sensory processing and cognitive demands provides important insights into the selective forces shaping animal nervous systems. We took advantage of the complex system of worker-to-soldier differentiation in the termitid Procornitermes araujoi, to investigate how a profound modification of body morphology followed by an irreversible shift in task performance are translated in terms of brain structure and size. This behavioural shift is characterised by a reduction of the once wide and complex behavioural repertoire of workers to one exclusively dedicated to nest defence (soldiers). In accordance with soldier’s reduced cognitive and sensory demands, we show here that differentiation of workers into soldiers is associated with a size reduction of the mushroom body (MB) compartments, higher-order brain regions responsible for multimodal processing and integration of sensory information, as well as learning, memory, and decision-making. Moreover, in soldiers, we found an apparent fusion of the medial and lateral MB calyces likely associated with its volume reduction. These results illustrate a functional neuroplasticity of the MB associated with division of labour, supporting the link between MB size and behavioural flexibility in social insect workers.

Sleep related rhythmic movement disorder: phenotypic characteristics and treatment response in a paediatric cohort

ObjectiveTo describe phenotypic, polysomnographic characteristics, impact, and treatment response in children with sleep related rhythmic movement disorder (SR-RMD). BackgroundThere is limited research on SR-RMD. We have developed a systematic clinical evaluation of children with SR-RMD to improve understanding and treatment. MethodsA retrospective chart review of 66 children at a UK tertiary hospital. Baseline assessment included validated screening questionnaires to study autism spectrum characteristics, general behaviour and sensory profile. A standardised questionnaire assessed impact on sleep quality and daytime wellbeing of child and family. Polysomnography data were collated. ResultsChildren were aged 0.9–16.3 years (78.8% male). 51.5% had a neurodevelopmental disorder, most commonly autism spectrum disorder. High rates of behavioural disturbance and sensory processing differences were reported, not confined to children with neurodevelopmental disorders. Parents reported concerns about risk of injury, loss of sleep and persistence into adulthood. Daytime wellbeing was affected in 72% of children and 75% of other family members. Only 31/48 children demonstrated rhythmic movements during video-polysomnography, occupying on average 6.1% of time in bed. Most clusters occurred in the settling period but also arose from N1, N2 and REM sleep and wake after sleep onset. Melatonin was prescribed to 52 children, all but one were extended-release preparations. 24/27 children with available data were reported to improve with melatonin. ConclusionsSR-RMD places a significant burden on child and family wellbeing. Our novel findings of sensory processing differences in this population and parent reported therapeutic response to extended-release melatonin offer potential avenues for future research.

The differential effect of age on upper limb sensory processing, proprioception and motor function.

Sensory processing consists in the integration and interpretation of somatosensory information. It builds upon proprioception but is a distinct function requiring complex processing by the brain over time. Currently little is known about the effect of aging on sensory processing ability, nor the influence of other covariates such as motor function, proprioception, or cognition. In this study, we measured upper limb passive and active sensory processing, motor function, proprioception, and cognition in 40 healthy younger adults and 54 older adults. We analyzed age differences across all measures and evaluated the influence of covariates on sensory processing through regression. Our results showed larger effect sizes for age differences in sensory processing (r=0.38) compared to motor function (r=0.18-0.22) and proprioception (r=0.10-0.27), but smaller than for cognition (r=0.56-0.63). Aside from age, we found no evidence that sensory processing performance was related to motor function or proprioception, but active sensory processing was related to cognition (β=0.30-0.42). In conclusion, sensory processing showed an age-related decline, while some proprioceptive and motor abilities were preserved across age.

Role of gastrointestinal health in managing children with autism spectrum disorder.

Children with autism spectrum disorders (ASD) or autism are more prone to gastrointestinal (GI) disorders than the general population. These disorders can significantly affect their health, learning, and development due to various factors such as genetics, environment, and behavior. The causes of GI disorders in children with ASD can include gut dysbiosis, immune dysfunction, food sensitivities, digestive enzyme deficiencies, and sensory processing differences. Many studies suggest that numerous children with ASD experience GI problems, and effective management is crucial. Diagnosing autism is typically done through genetic, neurological, functional, and behavioral assessments and observations, while GI tests are not consistently reliable. Some GI tests may increase the risk of developing ASD or exacerbating symptoms. Addressing GI issues in individuals with ASD can improve their overall well-being, leading to better behavior, cognitive function, and educational abilities. Proper management can improve digestion, nutrient absorption, and appetite by relieving physical discomfort and pain. Alleviating GI symptoms can improve sleep patterns, increase energy levels, and contribute to a general sense of well-being, ultimately leading to a better quality of life for the individual and improved family dynamics. The primary goal of GI interventions is to improve nutritional status, reduce symptom severity, promote a balanced mood, and increase patient independence.

A realist review of health passports for Autistic adults.

Autism is a normal part of cognitive diversity, resulting in communication and sensory processing differences, which can become disabling in a neurotypical world. Autistic people have an increased likelihood of physical and mental co-occurring conditions and die earlier than neurotypical peers. Inaccessible healthcare may contribute to this. Autism Health Passports (AHPs) are paper-based or digital tools which can be used to describe healthcare accessibility needs; they are recommended in UK clinical guidance. However, questions remained as to the theoretical underpinnings and effectiveness of AHPs. We undertook a systematic literature search identifying studies focused on AHPs for adults (aged over 16 years) from five databases. Included literature was subjected to realist evaluation. Data were extracted using a standardised form, developed by the research team, which considered research design, study quality for realist review and the Context, Mechanisms and Outcomes (CMOs) associated with each AHP tool. 162 unique records were identified, and 13 items were included in the review. Only one item was considered high quality. Contextual factors focused on the inaccessibility of healthcare to Autistic patients and staff lack of confidence and training in supporting Autistic needs. Interventions were heterogeneous, with most sources reporting few details as to how they had been developed. The most frequently included contents were communication preferences. Mechanisms were often not stated or were inferred by the reviewers and lacked specificity. Outcomes were included in four studies and were primarily focused on AHP uptake, rather than Outcomes which measured impact. There is insufficient evidence to conclude that AHPs reduce the health inequalities experienced by Autistic people. Using an AHP tool alone in a healthcare Context that does not meet Autistic needs, without the inclusion of the local Autistic community developing the tool, and a wider intervention to reduce known barriers to health inequality, may mean that AHPs do not trigger any Mechanisms, and thus cannot affect Outcomes.

Adolescents' and Adults' Perceptions of Sensory-Based Interventions: A Qualitative Analysis.

Adolescents and adults report that their sensory integration and processing differences affect their occupational performance and quality of life, thus requiring effective sensory-focused interventions. Researchers have yet to investigate this population's experience of occupational therapy interventions designed to remediate these challenges. To explore the perceived experience of adolescents and adults with respect to (1) response to intervention, (2) strategies offered to manage sensory differences, and (3) need for services on completion of an intervention. Retrospective, qualitative study. Zoom or phone call. Eleven adolescents and adults with sensory integration and processing differences who had previously completed occupational therapy interventions. Sensory-based intervention based on the principles of Ayres Sensory Integration® (ASI) and the Sensory Therapies and Research Frame of Reference. A semistructured interview to obtain data, followed by an in-depth analysis using an inductive coding process to group initial open codes into themes and common subthemes Results: Open codes were grouped into three core themes: (1) therapist-related factors (what the therapist did in treatment); (2) client-related factors (what the client experienced); and (3) follow-up (future needs of the clients). Four main subthemes of the client-therapist relationship emerged: (1) therapeutic alliance; (2) education and knowledge; (3) strategies, tools, and resources; and (4) future needs. This study provides a perspective on the experience of adolescents and adults specific to the impact of a sensory-focused occupational therapy intervention on their daily lives. This will help occupational therapists when designing interventions for current and future clients. What This Article Adds: This study highlights the need for further research addressing effective sensory-based interventions for adolescents and adults. It also captures which components of intervention clients deemed helpful and identifies potential targets for future intervention.
