Infants with Down Syndrome and Their Interactions with Objects: Development of Exploratory Actions after Reaching Onset
Peer reviewed Peer reviewed
Direct linkDirect link
de Campos, Ana Carolina; da Costa, Carolina Souza Neves; Savelsbergh, Geert J. P.; Rocha, Nelci Adriana Cicuto Ferreira – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
During infant development, objects and their functions are learned by means of active exploration. Factors that may influence exploration include reaching and grasping ability, object properties and the presence of developmental disorders. We assessed the development of exploratory actions in 16 typically-developing (TD) infants and 9 infants with…

Tudella, Eloisa; Pereira, Karina; Basso, Renata Pedrolongo; Savelsbergh, Geert J. P. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The purpose of the present study was to describe the rate of motor development in infants with Down syndrome in the age range of 3-12 months and identify the difficulties both in performance and acquiring motor skills in prone, supine, sitting and standing positions. Nineteen infants with Down syndrome and 25 healthy full term typical infants were…

Foot-Ground Interaction during Upright Standing in Children with Down Syndrome
Peer reviewed Peer reviewed

Pau, Massimiliano; Galli, Manuela; Crivellini, Marcello; Albertini, Giorgio – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
This study aimed to quantitatively characterize the main foot-ground contact parameters during static upright standing and to assess foot evolution with increasing age in young individuals affected by Down syndrome (DS). To this end, 99 children with DS of mean age 9.7 (1.7) were tested using a pressure sensitive mat, and the raw data were…

What Do We Know about the Atypical Development of Exploratory Actions during Infancy?
Peer reviewed Peer reviewed

de Campos, Ana Carolina; Savelsbergh, Geert J. P.; Rocha, Nelci Adriana Cicuto Ferreira – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Recent theoretical approaches to infant development have highlighted the importance of exploratory actions to motor, perceptual and cognitive development in infancy. However, the performance of infants exposed to risk factors when exploring objects has been frequently overlooked as a variable of interest. The aim of this study was to review…

How Much Change Is True Change? The Smallest Detectable Difference of the Preschool Imitation and Praxis Scale (PIPS) in Preschoolers with Intellectual Disabilities of Heterogeneous Aetiology
Peer reviewed Peer reviewed
Direct linkDirect link
Vanvuchelen, M.; Vochten, C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The teaching of imitation skills is often the first step in interventions for young learners with intellectual disabilities. The main goal of this study was to determine the smallest detectable difference (SDD) at 95% confidence of the Preschool Imitation and Praxis Scale (PIPS) in preschoolers with intellectual disabilities. Two raters…

Development of Reaching and Grasping Skills in Infants with Down Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
de Campos, Ana Carolina; Rocha, Nelci Adriana Cicuto Ferreira; Savelsbergh, Geert J. P. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Reaching and grasping skills have been described to emerge from a dynamic interaction between intrinsic and extrinsic factors. The aims of the study were to investigate the effect of such intrinsic factors as age and Down syndrome on the development of reaching and grasping skills and on overall gross motor skill, and to test the influence of the…

Developmental Milestones in Toddlers with Atypical Development
Peer reviewed Peer reviewed
Direct linkDirect link
Horovitz, Max; Matson, Johnny L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The attainment of developmental milestones was examined and compared in 162 infants and toddlers with developmental disabilities, including Down Syndrome (n = 26), Cerebral Palsy (n = 19), Global Developmental Delay (n = 22), Premature birth (n = 66), and Seizure Disorder (n = 29). Toddlers in the Seizures Disorder group began crawling at a…

Correlation between Dental Maturation and Chronological Age in Patients with Cerebral Palsy, Mental Retardation, and Down Syndrome
Peer reviewed Peer reviewed

Diz, P.; Limeres, J.; Salgado, A. F. P.; Tomas, I.; Delgado, L. F.; Vazquez, E.; Feijoo, J. F. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Determining a child's chronological age and stage of maturation is particularly important in fields such as paediatrics, orthopaedics, and orthodontics, as well as in forensic and anthropological studies. Some systemic conditions can cause abnormal physiological maturation, and skeletal maturation is usually more delayed than dental maturation.…
