Autonomic and Behavioral Responses of Children With Autism to Auditory Stimuli / Megan C. CHANG in American Journal of Occupational Therapy, Vol. 66/5 (septembre-octobre 2012)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 66/5 (septembre-octobre 2012) . - p. 567-576 Titre : Autonomic and Behavioral Responses of Children With Autism to Auditory Stimuli Type de document : texte imprimé Auteurs : Megan C. CHANG ; L. Diane Parham ; Blanche ERNA IMPERATORE Année de publication : 2012 Article en page(s) : p. 567-576 Langues : Anglais (eng) Mots-clés : Acoustique  Stimulation  Autisme Résumé : OBJECTIVES. We examined whether children with and without autism spectrum disorder (ASD) differ in autonomic activity at rest and in response to auditory stimuli and whether behavioral problems related to sounds in everyday life are associated with autonomic responses to auditory stimuli. METHOD. We measured skin conductance (SC) at rest and in response to auditory stimuli as well as behavioral responses using the Sensory Processing Measure (SPM) Home Form. Participants were 25 children with ASD and 25 typically developing (TD) children, aged 5–12 yr. RESULTS. The ASD group had significantly higher resting SC and stronger SC reactivity to tones than the TD group. Correlations between SC and SPM indicated that more severe auditory behavioral difficulties were associated with higher sympathetic activation at rest and stronger sympathetic reactivity to sound. CONCLUSION. High sympathetic reactivity to sound may underlie the difficult behavioral responses to sound that children with ASD often demonstrate.

Proprioceptive processing difficulties among children with autism spectrum disorders and developmental disabilities / Blanche ERNA IMPERATORE in American Journal of Occupational Therapy, Vol. 66/5 (septembre-octobre 2012)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 66/5 (septembre-octobre 2012) . - p. 621-624 Titre : Proprioceptive processing difficulties among children with autism spectrum disorders and developmental disabilities Type de document : texte imprimé Auteurs : Blanche ERNA IMPERATORE ; Gustavo REINOSO ; Stefanie BODISON ; Megan C. CHANG Année de publication : 2012 Article en page(s) : p. 621-624 Langues : Anglais (eng) Mots-clés : Proprioception  Autisme Résumé : OBJECTIVE. Sensory processing difficulties among children with autism spectrum disorders (ASD) have been extensively documented. However, less is known about this population's ability to process proprioceptive information. METHOD. We used the Comprehensive Observations of Proprioception (COP; Blanche, Bodison, Chang, & Reinoso, in press) to describe the proprioceptive difficulties experienced by children with ASD. A sample of 32 children with ASD, 26 children with developmental disabilities excluding ASD, and 28 typically developing control children were studied using the COP. RESULTS. Children with ASD present with proprioceptive processing difficulties that are different from those of children with developmental disabilities and their typically developing counterparts. Specific data, potential clinical applications, and directions for future research are described. CONCLUSION. Results suggest that the COP has useful clinical research applications. Further assessment of psychometric properties, clinical utility, and meaningful differences among diverse clinical populations are needed.
