Motor stereotypies in autism spectrum disorder: Clinical randomized study and classification proposal / ClAudia MELO in Autism, 27-2 (February 2023)  

Public ISBD [article]  inAutism > 27-2 (February 2023) . - p.456-471 Titre : Motor stereotypies in autism spectrum disorder: Clinical randomized study and classification proposal Type de document : Texte imprimé et/ou numérique Auteurs : ClAudia MELO, Auteur ; Tiago Pinto RIBEIRO, Auteur ; Catarina PRIOR, Auteur ; Camila GESTA, Auteur ; Vânia MARTINS, Auteur ; Guiomar OLIVEIRA, Auteur ; Teresa TEMUDO, Auteur Article en page(s) : p.456-471 Langues : Anglais (eng) Mots-clés : autism  epidemiologic determinants  intellectual disability  prevalence  stereotypies Index. décimale : PER Périodiques Résumé : Motor stereotypies are frequently reported in individuals with autism spectrum disorder, but determinants of stereotypies remain poorly understood. In this study, a randomized sample of children with diagnosis of autism spectrum disorder was investigated to identify the prevalence and determinants of stereotypies. A total of 134 children who carried the diagnosis of autism spectrum disorder were included (aged 2.3 “17.6 years; 79.1% male). Stereotypies were classified during a standardized protocol with video recording. The prevalence of stereotypies was 56.7%. Among 1198 captured stereotypies, hand/arm stereotypies were the most frequent. Thirty-five morphology patterns were identified, the most frequent being hand flapping, tapping, and jumping. In univariate analysis, an association was found between stereotypies and younger age (odds ratio=0.74), developmental delay, or intellectual disability (odds ratio=5.25), being nonverbal (odds ratio=0.06), epilepsy (odds ratio=3.89), Autism Diagnostic Interview “Revised-A score (odds ratio=1.17), Autism Diagnostic Interview “Revised-C score (odds ratio=1.25), and Autism Diagnostic Observation Schedule “2 score (odds ratio=1.65). After multivariate analysis, only younger age, being nonverbal, and Autism Diagnostic Interview “Revised-A and Autism Diagnostic Observation Schedule “2 scores remained as determinants of stereotypies. The prevalence of stereotypies in autism spectrum disorder was close to the values obtained in a previous meta-analysis and seems to represent a valid value. The combination of younger age, being nonverbal, and autism severity seems to increase the odds of stereotypies.

Prevalence and determinants of motor stereotypies in autism spectrum disorder: A systematic review and meta-analysis / Claudia MELO in Autism, 24-3 (April 2020)  

Public ISBD [article]  inAutism > 24-3 (April 2020) . - p.569-590 Titre : Prevalence and determinants of motor stereotypies in autism spectrum disorder: A systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Claudia MELO, Auteur ; Luis RUANO, Auteur ; Joana JORGE, Auteur ; Tiago PINTO RIBEIRO, Auteur ; Guiomar OLIVEIRA, Auteur ; Luis AZEVEDO, Auteur ; Teresa TEMUDO, Auteur Article en page(s) : p.569-590 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  meta-analysis  prevalence  stereotypies Index. décimale : PER Périodiques Résumé : Stereotypies are frequently reported in people with autism spectrum disorder (ASD) but remain one of the less explained phenomena. We aimed to describe, through a systematic review and a meta-analysis, the prevalence of motor stereotypies in ASD and study the factors that influence this prevalence. Our literature search included MEDLINE, Scopus, and PsycINFO databases. Quality and risk of bias were assessed. Thirty-seven studies were included and the median prevalence of motor stereotypies in ASD was 51.8%, ranging from 21.9% to 97.5%. The most frequent determinants associated with a higher number of stereotypies in ASD were a younger age, lower intelligence quotient, and a greater severity of ASD. Moreover, gender did not seem to influence the prevalence of stereotypies. Meta-analytic analysis showed that lower IQ and autism diagnosis (independent of IQ) are associated with a higher prevalence of motor stereotypies (odds ratio = 2.5 and 4.7, respectively). Limitations of the reviewed literature include the use of convenience samples, with small sizes and heterogeneous inclusion criteria, and the predominance of high-functioning autism individuals.
