An Introduction on the Benefits of Motor and Sports Activities on Sensory Processing in Children with Autism Spectrum Disorder (ASD)

Many studies have linked sensory sensitivities to feeding problems in children with autism spectrum disorder (ASD). Despite the importance of sensory processing for a variety of mealtime and eating skills, the specific sensory processes that may impact feeding problems in children with ASD have not been comprehensively reviewed. Thus, the goal of this systematic review was to understand the associations between sensory processing and feeding difficulties in children with ASD. This systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, CINAHL Plus with Full Text (EBSCOhost), Scopus (Elsevier), and Embase (Elsevier) databases were searched from their dates of inception through the final search date of April 19, 2022, for English language studies that examined both sensory processing and feeding among children with ASD. Studies were assessed for quality using the Joanna Briggs Institute critical appraisal tools. A total of 27 studies were included. Findings supported the existence of a relationship between sensory processing and feeding problems in children with ASD. Specifically, studies reported that overall scores on sensory processing measures as well as measures of oral sensory processing were frequently associated with feeding problems. This review supports the development of future feeding interventions focusing on sensory processing given the relationship between sensory processing and feeding problems among children with ASD. Future research should focus on utilizing consistent feeding assessments specific to children with ASD and collect information on medical diagnoses that can impact feeding in order to report on feeding more holistically in this population. https://doi.org/10.23641/asha.21453909.

Despite the high prevalence of sensory processing difficulties in children with autism spectrum disorder (ASD), little research has focused on the sex differences in sensory processing. Furthermore, there is a lack of knowledge on the female‐specific symptoms of ASD, contributing to later referral, diagnosis and intervention. In this study, we examined the sex differences in sensory processing symptoms in large cohorts of ASD children (N = 168; 26 females, 142 males) and typically developing (TD) children (N = 439; 209 females, 230 males). For this, we translated the sensory processing measure (SPM) and SPM – Preschool (SPM‐P) Home Forms to French. The SPM/SPM‐P are parent/caregiver questionnaires that assess typical behavioral responses to sensory stimuli. Overall, our results showed that the magnitude of the differences in sensory processing between males and females is larger in ASD children relative to TD children, with females showing more severe symptoms in Hearing, as well as Balance and Motion subscales. Additionally, linear discriminant analysis showed that the SPM/SPM‐P are good at discriminating TD children from ASD, children with higher accuracy rates for females than for males. These findings are discussed in light of the heterogeneity of sensory processing difficulties present in ASD. Overall, our results suggest that there seem to be female‐specific profiles in sensory processing difficulties in ASD. Implications of findings concerning sex differences in sensory processing and their potential for improving identification and diagnosis of ASD females are discussed.Lay SummaryThe present study examined sex differences in behavioral responses to sensory stimuli in children with autism spectrum disorder (ASD), and typically developing (TD) children. While there is a small trend for TD males to show more sensory processing atypicalities, female ASD children show significantly more atypical responses compared to their male counterparts. This has important implications for characterizing female autism profiles, and ultimately improving the chance for earlier detection, diagnosis and treatment.

Background Some children may encounter difficulties in processing sensory stimuli, which may affect their ability to participate in activities of daily living. Self-regulation abilities may also affect children on how to process different sensory experiences. The Sensory Processing and Self-Regulation Checklist (SPSRC) was developed as a single, parent-reported instrument for the examination of sensory processing and self-regulation difficulties in children. Aims This study is aimed at evaluating the psychometric properties of the SPSRC and examine the patterns of self-regulation and sensory processing in children with and without autism spectrum disorder (ASD). Methods and Procedures The contents of the SPSRC were validated by a group of experts, and a field test was subsequently conducted to examine the reliability and validity of this instrument in a sample of 997 typically developing children and 78 children with ASD. Outcomes and Results The results of the validation and field test analyses suggest that the SPSRC exhibits high internal consistency, good intrarater reliability, and a valid ability to measure and discriminate sensory processing and self-regulation in children aged 3–8 years with and without ASD. Conclusions and Implications The current results supported the reliability and validity of SPSRC to assess a child's sensory processing and self-regulation performance in activities of daily living. The study findings warrant further investigation to compare the performance of the SPSRC with laboratory-based tests, as this would better elucidate sensory responsivity in children with sensory modulation disorders from both clinical and research perspectives.

Sensory processing in children with autism spectrum disorder and the mental health of primary caregivers

Introduction: Sleep disturbances are highly prevalent among children with Autism Spectrum Disorder (ASD). Many studies on sleep in children with ASD have reported a high incidence of irregular sleep patterns and poor sleep quality. Recent research has highlighted the potential link between Sensory Processing (SP) difficulties and sleep disturbances in children with ASD. Therefore, a comprehensive knowledge of the evidence exploring the relationship between SP and sleep in children with ASD is needed to provide insights into targeted interventions and support strategies to improve sleep outcomes and the overall quality of life in children with ASD. Aim: This systematic review aims to investigate the relationship between SP and sleep in children with ASD aged 3 to 12 years. Materials and Methods: A comprehensive search of articles was conducted across databases, including Scopus, PubMed, and OTseeker. The following major keywords were used during the database searches: Sensory processing, sensory integration, sensory processing disorder, sensory integration disorder, sleep, sleep disorder, sleep problems, sleep disturbances, and autism spectrum disorder. The McMaster Critical Review Form for Quantitative Studies was utilised to evaluate the methodological quality of the included articles. Results: Through electronic and manual searches, 2,612 articles were identified after removing duplicates. Among these, nine articles published between January 2012 and December 2022 met the predetermined inclusion criteria. Of these, eight studies reported a statistically significant correlation between SP difficulties and sleep disturbances. Conclusion: This review underscores the significant impact of SP challenges on the sleep quality of children diagnosed with ASD, aged 3 to 12 years.

Sensory processing and alcohol use in adults with autism spectrum disorder

Background: During the past decade the prevalence of autistic spectrum disorders (ASD) has increased to 1% of the UK population. Anecdotal reports of children with ASD suggest they are atypical selective eaters who restrict their food intake based on idiosyncratic pre-requisites of texture and food presentation. Research has previously focused on the nutritional adequacy of such diets rather than underlying sensory processing capabilities that are known to be impaired in up to 90% of children with ASD (Leekham et al., 2007). Sensory processing skills, eating behaviour and parent-child relationships are intersecting aspects of ASD; and each play a role in achieving maximum potential in developing daily living skills. Previous research, relating sensory processing ability and eating behaviour, is limited. The aim of the study was to explore the relationship between sensory processing ability and eating behaviour in children with ASD. Methods: This analytical, exploratory study used purposive sampling, through approach of a parental support group for children with ASD in October 2009. Consent was sought from parents or guardians to complete two questionnaires; the validated Short Sensory Profile (SSP) and an eating behaviour questionnaire (EBQ) developed by the author and consisting of eight domains and four open questions. The domains of the EBQ were taste, texture, smell, behaviour, sound, environment, vision and touch. The domains were selected to reflect the SSP, and as a result of qualitative research from parental and specialist input and literature. Results of both questionnaires were statistically analysed using SPSS. Domains within each questionnaire were presented as mean (SD) and performance related data (SSP only) was presented as ‘typical performance’, ‘probable difference’ and ‘definite difference’ to indicate the degree of sensory processing difficulty (Dunn, 1999). Spearman Rank Correlation coefficient was used to explore correlations between domains within the two questionnaires. Ethical approval was gained from Leeds Metropolitan University Research Ethics Committee. Results: All parents (n = 20) participated in the study; completing questionnaires for 20 children (18 male, two female), mean age 10.8(2.6) years. Results of the SSP indicated that 71% of children in the study had sensory processing difficulties, of which auditory filtering (83%) and tactile sensitivity (68%) were ‘definite’ problem areas. Within the eating behaviour questionnaire, mealtime behaviour, vision, taste and smell were common areas that caused difficulty in daily life. Significant correlations between 20% of factors on the SSP and eating questionnaire were noted, the highest being SSP-taste/smell and EBQ taste (r = 0.9, P < 0.001) and SSP-taste/smell and EBQ vision (r = 0.9, P < 0.001). Discussion: This pilot study confirmed previous reports of sensory processing difficulties in children with autism (Tomcheck and Dunn, 2007) and provides preliminary data indicating a potential relationship between aspects of sensory processing ability and eating behaviour. Validation of the eating behaviour questionnaire is now required to establish a true link between these two areas and provide a sound basis for further longitudinal research that can accurately examine the impact of behaviour on eating in children with ASD and potential shifts in behaviour over time. Conclusion: This pilot study provides preliminary data linking sensory processing difficulty and eating behaviour and provides a basis for further research that supports effective and early interventions that improve quality of life, skills and prospects for those with ASD.

The purpose of this study is to investigate differences in sensory processing among age-matched children between ages 3 and 6 years with autism spectrum disorders (ASD) and those who are typically developing. Reported sensory processing abilities of 281 children with ASD were compared to age-matched peers who were typically developing, using the Short Sensory Profile (SSP). Ninety-five percent of the sample of children with ASD demonstrated some degree of sensory processing dysfunction on the SSP Total Score, with the greatest differences reported on the Underresponsive/ Seeks Sensation, Auditory Filtering, and Tactile Sensitivity sections. The ASD group also performed significantly differently (p < .001) on 92% of the items, total score, and all sections of the SSP. These findings, considered with similar published studies, begin to confirm the prevalence and types of sensory processing impairments in autism. Further research is needed to more clearly define patterns of sensory processing in people with ASD.

Sensory processing disorder (SPD) can be defined as a neurophysiological difficulty in modulating or interpreting sensory stimuli; it is often seen in children with autism spectrum disorder (ASD). We examined sensory processing among Israeli children with and without ASD, using an observational tool based on the clinicians’, child’s, parents’, and teachers’ self-reports. The Sensory Processing Measure (SPM) and the Sensory Adventure Measure (SAM) were administered to 57 children ages 6 to 10 years with and without ASD. Significant differences in sensory processing were found between groups, reported by clinicians (SAM), parents, and teachers (SPM). Evaluating SPD by a skilled clinician by observing the child adds further information beyond that collected from parents and teachers.

Comparing sensory processing in children with Down syndrome to a mental age matched sample of children with autism, other developmental disabilities, and typically developing children

Difficulties in sensory processing in children with autism have been known since the first descriptions of autism. The oldest and most recent theories of autism are based on the assumption that people with autism process sensory information differently than people without autism. This work aimed to examine sensory patterns and systems of sensory processing in children with autism and children with typical development through a systematic review of the relevant literature. From December 2022 to May 2023 by searching the online databases for publications in the field of autism and sensory processing, namely PubMed, Eric, Web of Science, Google Scholar, and Scopus, a total of 254 publications were identified. After applying inclusion criteria 5 publications that were analyzed. The search was performed by combining the keywords "autism", "sensory processing" "sensory processing disorder". The results show that children with autism manifest more atypical sensory processing than typically developing children. Furthermore, children with autism show differences in sensory patterns and systems, which indicate greater problems and greater concern within sensory processing. These results highlight the importance of developing treatments and interventions aimed at improving sensory processing in children with autism and alleviating the symptoms of atypical sensory processing.

Social Interaction and Atypical Sensory Processing in Children with Autism Spectrum Disorders

Abnormal sensory-based behaviors are a defining feature of autism spectrum disorders (ASD). Dr. A. Jean Ayres was the first occupational therapist to conceptualize Sensory Integration (SI) theories and therapies to address these deficits. Her work was based on neurological knowledge of the 1970’s. Since then, advancements in neuroimaging techniques make it possible to better understand the brain areas that may underlie sensory processing deficits in ASD. In this article, we explore the postulates proposed by Ayres (i.e., registration, modulation, motivation) through current neuroimaging literature. To this end, we review the neural underpinnings of sensory processing and integration in ASD by examining the literature on neurophysiological responses to sensory stimuli in individuals with ASD as well as structural and network organization using a variety of neuroimaging techniques. Many aspects of Ayres’ hypotheses about the nature of the disorder were found to be highly consistent with current literature on sensory processing in children with ASD but there are some discrepancies across various methodological techniques and ASD development. With additional characterization, neurophysiological profiles of sensory processing in ASD may serve as valuable biomarkers for diagnosis and monitoring of therapeutic interventions, such as SI therapy.

Objective: Autism spectrum disorder (ASD) is a prevalent neurodevelopmental disorder, often associated with co-occurring sleep disturbances. Children with ASD frequently experience sleep disruptions, which can worsen core symptoms and challenging behaviors. Sensory processing difficulties, commonly observed in children with ASD, may contribute to these sleep problems. Therefore, this study aims to investigate the impact of sensory processing patterns on sleep disturbances among children with ASD aged 3 to 11 years.Methods: A quantitative cross-sectional study design was employed with 74 children diagnosed with ASD. Child Sensory Profile-2 was used to assess sensory processing, and sleep disturbances were evaluated with the Child Sleep Habit Questionnaire. Partial Spearman’s rank correlation and multiple regression analyses were used to explore the relationships between sensory processing and sleep disturbances.Results: Partial Spearman’s rank correlation revealed a significant positive correlation between all four quadrants of the Child Sensory Profile-2 (seeking, avoiding, sensitivity, and registration), as well as sensory sections (auditory, touch, movement, body position, and oral) and sleep disturbances (p≤0.05) while controlling for severity of autism. Multiple regression analysis revealed that sensory avoidance behavior significantly predicted overall sleep disturbance scores in children with ASD (β=0.414, p=0.003).Conclusion: The study found that sensory avoiding demonstrates a significant association with sleep problems in children with ASD. These findings highlight the importance of incorporating sensory processing assessments in clinical evaluations of ASD children with sleep problems and suggest that sensory-based interventions may help improve their sleep quality.

Introduction. Sensory processing is a neurobiological process in which a person uses their senses, sends information to an appropriate reception and processing center, and responds to environmental stimulations. Previous research has shown that sensory processing difficulties are more common among people with autism spectrum disorder than among people of the typical population. Objectives. The aim of this paper was to determine the patterns of sensory processing in subjects of the typical population and subjects with autism spectrum disorder, as well as gender and age differences in sensory profiles in these groups of subjects. Methods. Using The Child Sensory Profile 2 as the measuring instrument, the characteristics of sensory processing were examined in 120 subjects of both genders, 60 subjects with autism spectrum disorder and 60 subjects of typical development, ages three to 13 years and 11 months. Results. The obtained results show that there are differences between the two groups of respondents and that these differences occur in all nine subscales of the instrument. It was found that subjects with autismspectrumdisorder hadmore difficulty in processing sensory information compared to subjects of the typical population, especially in the domain of tactile perception. The results also show that the quality of sensory information processing in both groups of respondents improved with age. In relation to the respondents' gender, the obtained differences were significant in the domain of the total score of the instrument, in favor of the boys, but this was not observed in the measurements on all subscales. Conclusion. In accordance with the above findings, when creating an individual educational plan, it is necessary to take into account all the specifics of sensory processing of children with autism spectrum disorder.
