A Quantitative Sensory Testing Approach to Pain in Autism Spectrum Disorders / Sarah VAUGHAN in Journal of Autism and Developmental Disorders, 50-5 (May 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-5 (May 2020) . - p.1607-1620 Titre : A Quantitative Sensory Testing Approach to Pain in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Sarah VAUGHAN, Auteur ; Francis MCGLONE, Auteur ; Helen POOLE, Auteur ; David J MOORE, Auteur Article en page(s) : p.1607-1620 Langues : Anglais (eng) Mots-clés : Autism  Pain  Quantitative sensory testing  Somatosensation Index. décimale : PER Périodiques Résumé : Sensory abnormalities in autism has been noted clinically, with pain insensitivity as a specified diagnostic criterion. However, there is limited research using psychophysically robust techniques. Thirteen adults with ASD and 13 matched controls completed an established quantitative sensory testing (QST) battery, supplemented with measures of pain tolerance and central modulation. The ASD group showed higher thresholds for light touch detection and mechanical pain. Notably, the ASD group had a greater range of extreme scores (the number of z-scores outside of the 95% CI > 2), dynamic mechanical allodynia and paradoxical heat sensation; phenomena not typically seen in neurotypical individuals. These data support the need for research examining central mechanisms for pain in ASD and greater consideration of individual difference.

Tactile Perception in Adults with Autism: a Multidimensional Psychophysical Study / Carissa J. CASCIO in Journal of Autism and Developmental Disorders, 38-1 (January 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-1 (January 2008) . - p.127-137 Titre : Tactile Perception in Adults with Autism: a Multidimensional Psychophysical Study Type de document : Texte imprimé et/ou numérique Auteurs : Carissa J. CASCIO, Auteur ; Grace T. BARANEK, Auteur ; Francis MCGLONE, Auteur ; Stephen FOLGER, Auteur ; Vinay TANNAN, Auteur ; Kevin A. PELPHREY, Auteur ; Gregory ESSICK, Auteur Année de publication : 2008 Article en page(s) : p.127-137 Langues : Anglais (eng) Mots-clés : Autism Sensory Tactile Psychophysics CT-afferents Index. décimale : PER Périodiques Résumé : Although sensory problems, including unusual tactile sensitivity, are heavily associated with autism, there is a dearth of rigorous psychophysical research. We compared tactile sensation in adults with autism to controls on the palm and forearm, the latter innervated by low-threshold unmyelinated afferents subserving a social/affiliative submodality of somatosensation. At both sites, the groups displayed similar thresholds for detecting light touch and innocuous sensations of warmth and cool, and provided similar hedonic ratings of the pleasantness of textures. In contrast, increased sensitivity to vibration was seen in the autism group on the forearm, along with increased sensitivity to thermal pain at both sites. These findings suggest normal perception along with certain areas of enhanced perception in autism, consistent with previous studies.
