Gross Motor Development, Movement Abnormalities, and Early Identification of Autism

Gross motor development (supine, prone, rolling, sitting, crawling, walking) and movement abnormalities were examined in the home videos of infants later diagnosed with autism (regression and no regression subgroups), developmental delays (DD), or typical development. Group differences in maturity were found for walking, prone, and supine, with the DD and Autism-No Regression groups both showing later developing motor maturity than typical children. The only statistically significant differences in movement abnormalities were in the DD group; the two autism groups did not differ from the typical group in rates of movement abnormalities or lack of protective responses. These findings do not replicate previous investigations suggesting that early motor abnormalities seen on home video can assist in early identification of autism

Trastorno Desintegrativo de la Infancia: un estudio de caso único analizando sistemáticamente grabaciones familiares

Childhood disintegrative disorder (CDD) is a rare pervasive developmental disorder that involves regression after a period of at least 2 years of typical development. This case study presents data from family home movies, coded by reliable raters using an objective coding system, to examine the trajectory of development in one child with a reported regression at 48 months of age. Coding substantiated parent reports of mostly typical early development, followed by later catastrophic loss of skills across many developmental domains. Differential diagnosis of CDD and autism with regression is discussed.Consejeria de Educación de la Comunidad de MadridUniversidad Autónoma de MadridNICHD U19-HD35468 (Project 2, Regression)Depto. de Psicología Experimental, Procesos Cognitivos y LogopediaFac. de PsicologíaTRUEpu
