“…This study did not show any association of foot rotation asymmetry with gender, ethnicity, other comorbidities, physiotherapy, or occupational therapy interventions. Rihtman et al 18 did not observe any association between gender and motor integration; however, some other previous studies on DS reported that girls have better motor development, and boys who were underweight and/or presented cardiac alterations had a slower development 19 . Malak et al 20 carried out a study with DS children in which the researchers confirmed that the upstanding and gait skills were delayed even when physiotherapy was performed.…”

Introduction: Down syndrome individuals have different gait patterns, which include specific characteristics such as foot rotation asymmetry. Objective: The aim of this study was to analyze the relationship between this asymmetry and the previous acquisition of hands-and-knees crawling in Down syndrome children, as well as the probable association of this gait to gender, ethnicity, comorbidities, physiotherapy, and occupational therapy interventions. Methods: In this cross-sectional study, 361 children with or without foot rotation asymmetry were selected. An online questionnaire was administered to the parents or guardians of those children. Results: Hands-and-knees crawling decreased the prevalence of foot rotation asymmetry in Down syndrome children. The longer it took for walking onset, the higher the prevalence of this asymmetry. Indeed, for each month of delay there was a 7% increase in prevalence. There was a significant relationship between orthopedic alterations in knees or flat feet and foot rotation asymmetry. There was no significance related to gender, ethnicity, other comorbidities, physiotherapy or occupational therapy interventions. Conclusion: The findings in this study revealed that foot rotation asymmetry may be related to the acquisition of the motor skills described above, especially with regards to hands-and-knees crawling and walking onset.

“…A sizable minority of infants with DS are born prematurely (Aoki et al . ), although official prematurity prevalence data are difficult to obtain. Each of these biomedical factors – congenital heart defects, significant illness and premature birth – are known to impact cognitive outcomes in the general population of infants without DS (Mahle ; Bhutta et al .…”

“…Approximately 44-50% of infants with DS are born with a congenital heart defect (American Academy of Pediatrics 2001; Freeman et al 2008), and many others have a history of illness (American Academy of Pediatrics 2001; Goffinski et al 2015;Martin et al 2018). A sizable minority of infants with DS are born prematurely (Aoki et al 2018), although official prematurity prevalence data are difficult to obtain. Each of these biomedical factorscongenital heart defects, significant illness and premature birthare known to impact cognitive outcomes in the general population of infants without DS (Mahle 2001;Bhutta et al 2002;Karsdorp et al 2006), but the link between these risk factors and infant cognition in DS remains unclear.…”

Background While delays in cognitive development are detectable during early development in Down syndrome, the neuropsychological and biomedical underpinnings of cognitive skill acquisition in this population remain poorly understood. Method To explore this issue, 38 infants with Down syndrome [mean chronological age = 9.65 months; SD = 3.64] completed the Bayley Scales of Infant Development‐III and a set of laboratory tasks that measured sustained attention (duration of visual attention during a 1‐min object exploration task), attention shifting (mean latency to shift attention on an alternating object presentation task) and visual short‐term memory (dishabituation to a novel object on a change preference task). Results Latency to shift attention was negatively associated with Bayley Cognitive Scale raw scores, even when controlling for the effects of chronological age, r (33) = −.41, P = .02. In addition, prematurity status was associated with latency to shift attention. Conclusions Early attention shifting may be an important factor that facilitates overall cognitive skill acquisition in infants with Down syndrome, and premature birth may be a risk factor for difficulties on this dimension.

“…Specifically, we inspect the score distributions of two caregiver report measures, the Orienting/Regulation dimension of the Infant Behavior Questionnaire-Revised (IBQ-R) [34] and the Communication and Symbolic Behavior Scales Infant Toddler Checklist (CSBS-ITC) [42]. The effects of prematurity [43] and CHD [36], both biomedical risk factors associated with DS, as well as caregiver education level, are also investigated. We then characterize the predictive value of infant regulatory function for social communication performance six months later.…”

Early Regulatory Skills and Social Communication Development in Infants with Down Syndrome

Children with Down syndrome (DS) demonstrate substantial variability in communication and language outcomes. One potential source of variability in this skill area may be early regulatory function. Characterizing the early link between regulatory function and early social communication may benefit infants with DS at risk of difficulties with social communication and language skill acquisition. Forty-three infants with DS were assessed at two time points, six months apart. At Time 1, the average chronological age was 9.0 months (SD = 3.9) and caregivers completed the Infant Behavior Questionnaire-Revised (IBQ-R) to assess regulatory function. Six months later, caregivers rated infant communication at the second visit using the Communication and Symbolic Behavior Scales Infant Toddler Checklist (CSBS-ITC). Infant developmental level was assessed at both visits using the Bayley Scales of Infant and Toddler Development, Third Edition and caregivers reported on developmental history and biomedical comorbidities. Infant regulatory function at Time 1 predicted social communication outcomes at Time 2, six months later. Findings from this study suggest that elevated risk for pronounced communication challenges may be detectable as early as infancy in DS.
