Aim: To report prospective longitudinal data of early vocaliszations of infants identified "at-risk" of cerebral palsy (CP) for early identification of communication impairment.
Method: This case-control longitudinal prospective cohort study reports on the assessment of 36 infants, 18 identified as at-risk of CP at the time of enrolment and 18 typically developing (TD) children, at three time points: 6 months, 9 months and 12 months of age, Data were obtained through criterion and norm referenced assessments of vocaliszation behaviors.
Results: Early vocal behaviors of infants identified as at-risk of CP did not differ from their age matched peers at 6 months of age, however, significant group differences emerged at 9 and 12 months when pre-canonical and canonical babble typically emerge. Generalized linear mixed models analysis showed that the rate of development of early language ability and more complex speech-related vocal behaviors was slower for infants at risk of CP when compared to TD infants, with over 75% of infants with CP showing below normal vocal production and impaired language by 12 months of age.
Interpretation: Our data suggest characteristics of infant vocalizations associated with pre-canonical and canonical babbling provide a strong evidence base for predicting communication outcomes in infants at risk of CP.
Purpose: Explore effects of age, sex, and motor ability level on balance capabilities in preschoolers with and without Cerebral Palsy (CP).
Method: PBS was administered to 477 children 24 through 59 months: 258 with typical development (TD) and 219 with CP GMFCS levels I, II and III.
Results: 3-way ANOVA indicated PBS scores were significantly affected by age (F4,437=26.95, p<0.0001, η2p=0.198), motor ability level (F3,437=482.15, p<0.0001, η2p=0.768) and sex (F1,437=4.64, p<0.03, η2p=0.01) with significant interaction between motor ability level and age (F 12,437=5.25, p<0.001, η2p=0.126). Children's performance on individual items was analyzed by age, sex and motor ability level.
Conclusion: Children with TD outperformed children with CP GMFCS level I 36-59 months and children with CP GMFCS levels II and III 24-59 months. Expected performance values for children with TD and children with CP, ages 24-59 months, at GMFCS levels I, II and III are provided.
Aim: This study sought to evaluate the accuracy of the Ages and Stages Questionnaires 3rd Edition (ASQ-3) in identifying developmental delay (DD) in children with congenital heart disease (CHD) born at term who underwent surgical repair.Methods: Participants had to complete ASQ-3 and Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) at 12 and 24 months. A child was considered at risk of DD for a ASQ-3 domain when he scored below the cutoff (≤-1SD or ≤-2SD). A child had a DD in a BSID-III domain when the score was ≤-1SD. The validity for each ASQ-3 domain and for overall ASQ-3 was measured.Results: At 12 months (n = 64), overall ASQ-3 (≤-2SD) sensitivity was 88%, specificity 74%. At 24 months (n = 82), overall ASQ-3 (≤-2SD) sensitivity was 74%, specificity 88%.Conclusion: The results support the utility of the ASQ-3 for screening the overall risk of DD in children with CHD.
