objectives: down syndrome (ds) is the most common multiple congenital anomaly syndrome associated with a developmental disability. children with down syndrome have delay in both motor and mental age. this study carried out to explore relationship between mental and motor age of children with ds. methods: a cross-sectional study was conducted on 60 participants with ds (5 to 7 years old) using r...

AIM This study is aimed to investigate differences between cognitive, language and motor development of high-risk infants related to birth weight and gestational age. MATERIAL AND METHODS One hundred sixty high-risk infants who were born 32 weeks, 1 500 gr and below included in this study. According to corrected age, 58 infants were 1 month, 72 were at 4 months, 82 were at 8 months and 65 wer...

The effects of advanced age and cognitive resources on the course of skill acquisition are unclear, and discrepancies among studies may reflect limitations of data analytic approaches. We applied a multilevel negative exponential model to skill acquisition data from 80 trials (four 20-trial blocks) of a pursuit rotor task administered to healthy adults (19-80 years old). The analyses conducted ...

PURPOSE The Alberta Infant Motor Scale (AIMS) is a standardized motor assessment for young infants. This study aimed to examine the reliability of the AIMS in a group of infants born at or before 29 weeks of gestation. METHODS Fifty-nine infants born preterm were recruited. Two experienced pediatric physical therapists participated in this reliability study. Infants were assessed at 4, 8, 12,...

STUDY OBJECTIVES To assess the effects of delayed high-school start times on sleep and motor vehicle crashes. METHODS The sleep habits and motor vehicle crash rates of adolescents from a single, large, county-wide, school district were assessed by questionnaire before and after a 1-hour delay in school start times. RESULTS Average hours of nightly sleep increased and catch-up sleep on weeke...

OBJECTIVE To evaluate the need of chronological age correction according to the degree of prematurity, when assessing gross motor development in preterm infants, during the first year of life. METHOD Cohort, observational and prospective study. Alberta Infant Motor Scale (AIMS) was used to evaluate 43 preterm infants with low risk for motor neurological sequelae, during the first year of corr...

background: to determine whether using mechanical ventilation in neonatal intensive care unit (nicu) influences motor development of low birth weight (lbw) infants and to compare their motor development with normal birth weight (nbw) infants at the age of 8 to 12 months using peabody developmental motor scale 2 (pdms-2). methods: this cross sectional study was conducted on 70 lbw infants in two...

BACKGROUND development assessment of preterm infants. AIM to evaluate the association between the gestational ages (GA) of premature infants with the global motor development as well as with early signs of sensory oral motor development delay, and to verify a possible association between them. METHOD an exploratory study that assessed the development of 55 infants with corrected chronologic...
