Abstract
BACKGROUND At-risk infants are predisposed to major and minor neurodevelopmental disorders due to various biological and environmental factors. OBJECTIVE This study aimed to investigate the relationship between gross motor maturation from 1 to 18 months and gross motor performance in the preschool period, as well as the risk of developmental coordination disorder (DCD) in at-risk infants, referred to the Family Counselling Center of the Turkish Spastic Children's Foundation (FCCTSCF) between 2014 and 2016. METHODS Fifty-seven children who had their gross motor maturation assessed between 1 and 18 months at the FCCTSCF were re-evaluated in the preschool period. The Alberta Infant Motor Scale (AIMS) was used to evaluate gross motor maturation between 1 and 18 months. In contrast, the Gross Motor Function Measure-88 and the Developmental Coordination Disorder Questionnaire were used to assess gross motor performance in the preschool period. RESULTS Of the at-risk infants included in the study, 45.6% were evaluated as having typical development, 21% were identified as having cerebral palsy (CP), and 33.3% were determined to be at risk for DCD. Children with CP and those at risk for DCD were found to have lower percentile ranks on the past AIMS test compared to the healthy group (p = 0.001). A significant positive correlation was found between the Alberta Infant Motor Scale and the Gross Motor Function Measure-88 (p = 0.014). CONCLUSION In the clinical follow-up of at-risk infants, those who scored low on AIMS should be monitored for future risk of DCD and minor disorders, even if major neurological issues such as cerebral palsy are not detected.

Abstract
OBJECTIVE Trunk control is associated with gross motor development. This study examines the relationship between segmental trunk control and gross motor performance in low birth weight (LBW) infants. METHODS A total of 42 LBW infants and 43 normal birth weight (NBW) infants aged 3-9 months were sampled for this cross-sectional study. All infants were evaluated one time by the Segmental Assessment Trunk Control (SATCo) and the Alberta Infant Motor Scale (AIMS). RESULTS Statistically high and significant correlations were found between gross motor performance and segmental trunk control in all sample populations (r = 0.835; p = .001). No statistically significant difference was found regarding the segmental trunk control between the groups (p = .119). The LBW infants with atypical motor development had poorer trunk control than the LBW infants with typical development (f = 5.480; p = .001). CONCLUSION Our results show that LBW infants with atypical motor development had poorer trunk control than LBW infants with typical motor development. It was found that the segmental trunk controls of LBW infants were 0.398 times lower than in NBW infants.

Abstract
Background Proper motor development can be influenced by a range of risk factors. The resulting motor performance can be assessed through quantitative and qualitative analysis of posture and movement patterns. Methods This study was designed as the cohort follow-up of the motor assessment and aimed to demonstrate, in a mathematical way, the impact of particular risk factors on elements of motor performance in the 3rd month and the final motor performance in the 9th month of life. Four hundred nineteen children were assessed (236 male and 183 female), including 129 born preterm. Each child aged 3 month underwent a physiotherapeutic assessment of the quantitative and qualitative development, in the prone and supine positions. The neurologist examined each child aged 9 month, referring to the Denver Development Screening Test II and assessing reflexes, muscle tone and symmetry. The following risk factors were analyzed after the neurological consultation: condition at birth (5th min Apgar score), week of gestation at birth, intraventricular hemorrhage, respiratory distress syndrome, and the incidence of intrauterine hypotrophy and hyperbilirubinemia determined based on medical records. Results A combination of several risk factors affected motor development stronger than any one of them solely, with Apgar score, hyperbilirubinemia, and intraventricular hemorrhage exhibiting the most significant impact. Conclusions Premature birth on its own did not cause a substantial delay in motor development. Nonetheless, its co-occurrence with other risk factors, namely intraventricular hemorrhage, respiratory distress syndrome, and hyperbilirubinemia, notably worsened motor development prognosis. Moreover, improper position of the vertebral column, scapulae, shoulders, and pelvis in the third month of life may predict disturbances in further motor development.

Abstract
Abstract Objective: To perform a longitudinal investigation of risk factors in premature infants’ cognitive, motor, and language development. Methods: Thirty-three preterm infants were assessed at 4, 8, and 12 months of corrected age, using the Bayley-III Scales. Parents completed questionnaires regarding development opportunities at home, parenting practices and knowledge. Results: Significant associations were found (1) at 4-months between cognitive scores and family income, variety of stimuli, availability of toys, parenting practices and knowledge; language and parenting practices; and motor skills and parenting practices; (2) at 8-months between cognitive score and length of stay in the Neonatal Intensive Care Unit (NICU), gestational age, birth weight, toys, and parenting knowledge; language and toys; and motor skills and toys and parenting knowledge; (3) at 12-months between cognitive scores and length of stay in the NICU, family income, breastfeeding, toys, and parenting knowledge; language and income and toys; and motor scores and length of stay in the NICU, gestational age, income, stimuli, toys, and parenting knowledge. Regression analyses indicated that: for (1) cognitive development, stimulus variety explained 72% of the model variance at 4 months of age; time at the NICU explained 67 and 43% at 8 and 12 months of age, respectively, and breastfeeding time explained 41% of the model variance at 12 months; (2) for language development, family income explained 42% of the model variance at 12 months; and for motor development (3), time at the NICU explained 80% of the model variance at 12 months. Conclusions: The development over the first year of life is not explained by the severity of birth conditions and associated morbidities only, but also by parenting practices.

Abstract
RESUMO O estudo objetivou investigar as associações entre práticas e conhecimentos dos cuidadores e o desempenho motor de crianças de zero a 2 anos de idade. Participaram 53 crianças avaliadas com a Peabody Developmental Motor Scale-2. Seus familiares responderam a dois questionários de cuidados parentais, a Daily Activities of Infant Scale e Knowledge of Infant Development Inventory, e um questionário de nível socioeconômico. Identificaram-se correlações significativas entre desempenho motor e comprimento (p=0,001) e peso atual da criança (p=0,005). Em relação às práticas parentais, correlações significativas foram observadas entre o desempenho motor e posturas durante a alimentação (p≤0,001), banho (p≤0,001), trocas de roupa (p=0,024), sono (p=0,035) e no colo (p=0,001), bem como em brincadeiras tranquilas (p=0,003), ativas (p=0,024) e oportunidades de passeio (p=0,004) da criança. A análise de regressão evidenciou que o modelo com posturas na alimentação, trocas de roupas e brincadeiras explicou 79% da variância no desempenho motor (p<0,001). As oportunidades de trocas posturais durante a alimentação, a higiene do bebê e brincadeiras ativas, influenciaram aquisições de habilidades motoras mais sofisticadas nos primeiros anos de vida.

Abstract
Purpose: We evaluated the interrater and intrarater reliabilities of the Korean version of the Alberta Infant Motor Scale (K-AIMS). Methods: For the interrater reliability test, six raters participated in the K-AIMS evaluation using video clips of 70 infants (aged between 0 and 18 months). One rater participated in an intrarater reliability test. Among 70 infants, 46 were born preterm and 24 were born full term. A total of 58 AIMS items were evaluated for supine, prone, sitting, and standing positions. A reliability analysis was conducted using ICC and Fleiss’ kappa. Results: The highest Fleiss’ kappa was found for the 4–7 months group for sitting (K = 0.701–1.000) and standing (K = 0.721–1.000), while the lowest K was the 3 months or under group for standing (K = 0.153–1.000). We found higher Fleiss’ kappa statistics when all infants were evaluated without grouping for the three positions (K = 0.727–1.000), except standing (K = 0.192–1.000), for the interrater analysis. Conclusion: Our results demonstrate the good reliability for the Korean version of the AIMS for Korean infants (preterm and full term).

Abstract
INTRODUCTION Risk factors are biological or environmental characteristics increasing the likelihood of delays in child development. Meanwhile, protective factors are conditions that can minimize risks and favor the acquisition of skills. Infants with risk indicators for hearing loss (RIHL) tend to live in less stimulating environments which may lead to lower cognitive, language, and motor development. OBJECTIVE To compare the cognitive, language, and motor development of infants under the influence of risk and protective factors. METHOD A cross-sectional observational study in which 259 infants aged 8-10 months were assessed for cognitive, language, and motor development using the Bayley Scales of Infant and Toddler Development - Third Edition (BSITD-III). The groups were formed according to the presence or absence of RIHL and the quality of the resources, being: SG-AE (Study Group with Adequate Environment), SG-IE (Study Group with Inadequate Environment), CG-AE (Compared Group with Adequate Environment)) and CG-IE (Compared Group with Inadequate Environment). Affordances were assessed using the questionnaire Affordances in the Home Environment for the Motor Development - Infant Scale (AHEMD-IS). The groups were compared using the Chi-square test or the Kruskal-Wallis test, followed by Dunn's multiple comparison test. The level of significance adopted was 5%. RESULTS Infants from the CG-AE performed better than the other groups in cognition and motor skills. The CG-AE language was statistically superior to the SG-IE. SG-IE showed the highest frequency of delays in all domains. CG-IE and SG-AE showed a similar frequency of delays. Adequate environment associated with the absence of RIHL (CG-AE) leads to better cognitive, language, and motor performances. CONCLUSION Biological and environmental risk factors have a similar impact on development, but the accumulation of both tends to increase the risks of developmental delay. The absence of RIHL and quality environments worked as protective factors and favored the acquisition of skills.

Abstract
In this study, we analyzed whether 6-month gross and fine motor skills were related to 12-month gross and fine motor skills and cognitive development, controlling for 6-month cognitive skills, and neonatal status (extremely low gestational age ELGA ≤ 28 weeks vs. full-term FT ≥ 37 weeks). We also investigated, at 6 months, predictive indexes for motor and cognitive delay at 12-months. We assessed 40 infants (20 ELGA and 20 FT) at 6 and 12 months (corrected age for the ELGA infants). Six-month gross motor skills were related to 12-month gross motor, fine motor, and cognitive skills and predicted 12-month gross motor delay. Six-month cognitive skills explained an additional amount of variance of 12-month gross motor skills, whereas neonatal status explained an additional amount of variance of 12-month cognitive skills. Considering the intradomain and cross-domain cascading effects of early gross motor skills on later motor and cognitive development, these skills should be repeatedly assessed in ELGA infants in the first year of life for early identification of infants with delayed gross motor skills and implementation of customized interventions.

Abstract
Purpose: To explore the relationship between segmental trunk control and specific gross motor skills at 4, 8 and 12 months of (corrected) age in young infants.Methods: Thirty-one preterm infants and 30 full-term infants were recruited by convenience. All infants were tested using the Segmental Assessment of Trunk Control and the Alberta Infant Motor Scale at 4, 8 and 12 months of age.Results: The gross motor function in supine at 4 months and in the standing position at 12 months was significantly delayed in the preterm infants. Positive correlations were found between segmental trunk control levels and specific motor skills in prone, supine, sitting and standing positions at 8 and 12 months of age.Conclusion: This report was the first to demonstrate the association between segmental trunk control and specific gross motor skills in young infants. This new information provides clinicians with greater understanding about infant development.

Abstract
Purpose: No previous study examined trunk control development in preterm infants. The present study examined the longitudinal development of segmental trunk control from 4 to 12 months of (corrected) age in preterm infants in comparison with full-term infants.Methods: Thirty-one preterm infants and 30 full-term infants were recruited. All infants were tested monthly using the Segmental Assessment of Trunk Control and the Alberta Infant Motor Scale at 4, 8 and 12 months of age.Results: Segmental trunk control development was significantly delayed in the preterm infants. Statistically significant positive correlations were found between trunk control status and gross motor skills.Conclusion: This was first study showing that segmental trunk control development was significantly different in preterm infants. Segmental trunk control and gross motor performance were coupled in young infants. A dual focus on training upright trunk control and specific motor skills may maximise therapy outcomes for infants with motor delay.

Abstract
Aim To investigate the relationship between motor and sensory development in the first 4 months of life in preterm infants born at 32 gestational weeks and below. Material and Methods The study consisted of 56 high-risk infants with a corrected age of 1 month who were born at 32 gestational weeks and stayed in the neonatal intensive care unit for at least 15 days. Neuro Sensory Motor Developmental Assessment and Infant Sensory Profile-2 were used for evaluation. These assessments were applied to preterm infants at the 1st and 4th months. The results of assessments were analyzed using the Wilcoxon test. The relationship between the results of motor and sensory assessments was analyzed using Spearman's correlation test. Results The mean gestational age of the infants was 29.58±2.09 weeks, their birth weights were 1233.87±251.22 grams, and their duration of stay in the neonatal intensive care unit was 26.48±9.58 days. There was a statistically significant difference between the Neuro Sensory Motor Developmental Assessment and Infant Sensory Profile-2 scores between the 1st and 4th months (p<0.05). It was found that there was a risk in terms of sensory development in 86-91% of the preterm infants at the 1st month and in 69-85% at the 4th month. There was moderate-strong degree of significant relationship between motor and sensory development. Conclusion Considering the findings of our study, preterm infants are at risk for motor and sensory development. There is, therefore, a need for future research to investigate the effect of early sensory-based intervention approaches on preterm infants.

Abstract
The authors' aim was to verify the correlation between segmental trunk control and gross motor performance in healthy preterm (PT) and full-term (FT) infants aged 6 and 7 months and to verify if there are differences between groups. All infants were assessed at 6 and 7 months by means of Segmental Assessment of Trunk Control (SATCo) to identify the exact level of segmental trunk control and Alberta Infant Motor Scale (AIMS) to measure gross motor performance. A significant correlation between segmental trunk control and gross motor performance was found in healthy PT infants at 7 months and FT infants at 6 months. PT infants showed a delay on segmental trunk control at 6 and 7 months and in supported standing posture at 6 months compared with FT infants. Segmental trunk control and gross motor performance showed an important relationship in healthy PT and FT infants, mainly in sitting posture.

Abstract
Following a request from the European Commission, the Panel on Nutrition, Novel Foods and Food Allergens (NDA) revised its 2009 Opinion on the appropriate age for introduction of complementary feeding of infants. This age has been evaluated considering the effects on health outcomes, nutritional aspects and infant development, and depends on the individual's characteristics and development. As long as foods have an age-appropriate texture, are nutritionally appropriate and prepared following good hygiene practices, there is no convincing evidence that at any age investigated in the included studies (< 1 to < 6 months), the introduction of complementary foods (CFs) is associated with adverse health effects or benefits (except for infants at risk of iron depletion). For nutritional reasons, the majority of infants need CFs from around 6 months of age. Infants at risk of iron depletion (exclusively breastfed infants born to mothers with low iron status, or with early umbilical cord clamping (< 1 min after birth), or born preterm, or born small-for-gestational age or with high growth velocity) may benefit from earlier introduction of CFs that are a source of iron. The earliest developmental skills relevant for consuming pureed CFs can be observed between 3 and 4 months of age. Skills for consuming finger foods can be observed in some infants at 4 months, but more commonly at 5-7 months. The fact that an infant may be ready from a neurodevelopmental perspective to progress to a more diversified diet before 6 months of age does not imply that there is a need to introduce CFs. There is no reason to postpone the introduction of potentially allergenic foods (egg, cereals, fish and peanut) to a later age than that of other CFs as far as the risk of developing atopic diseases is concerned. Regarding the risk of coeliac disease, gluten can be introduced with other CFs.

Abstract
Abstract Introduction: The motor trajectory of pre-term children is an important indicator of health during infancy, since alterations may be a signal for the need of professional intervention. Objective: To describe percentiles and motor development curves for Brazilian preterm infants in the first year of life, determining the reference values for categorization of motor performance assessed by the AIMS. Methods: Participated in this cross-sectional study 976 children born pre-term, newly-born to 12 months of corrected age. The Alberta Infant Motor Scale (AIMS) was used to assess participants’ motor development. The scores of the Brazilian norms were used as comparison criteria. Results: Children born pre-term showed lower scores compared to children born full-term indicating the need for a specific percentile curve for that population. The scores differentiated at P1 to P99 percentiles allowing for the categorization of children with typical development, at risk and with atypical development. At 0, 4, 8, 9, 10, 11 and 12 months an overlapping of extreme percentiles (P1, P5 and P10; P90, P95 and P99) was observed, but not in the other percentiles. Conclusion: The percentiles described indicate that preterm children presented lower motor performance than full-term children and AIMS has discriminant power for the clinical evaluation of these children. The developmental curves showed lower capacity for behavioral differentiation in the extreme percentiles.

Abstract
BACKGROUND Efficient trunk control is crucial in infant motor development when infants first learn how to move against gravity. Traditional assessments of trunk control commonly treat the trunk as one unit but the Segmental Assessment of Trunk Control (SATCo) assesses trunk control segment by segment. Good reliability and validity of the SATCo have been proved in children with neuro-disability but not yet validated in young infants. The present study was to examine if the SATCo was reliable, valid and responsive for infants aged 4 to 9 months. METHODS Infants born at full-term and at less than 30 weeks of gestation were recruited and assessed using the SATCo monthly from 4 to 9 months of age (corrected for prematurity). Intra-class correlation coefficients (ICC) were used to examine intra- and inter-rater reliability between 2 raters. The ability of the SATCo to demonstrate differences between the full-term and preterm infants was examined using the Mann Whitney U test. The responsiveness of the SATCo on the full-term infants was tested using the Friedman test. RESULTS Twenty full-term (mean gestation = 38.7 weeks; birthweight = 3019.9 g) and 20 preterm infants (mean gestation = 27.2 weeks; birthweight = 989.6 g) were recruited. The intra and inter-rater reliability of the SATCo levels on full-term infants was good (all ICC > 0.75), except inter-rater reliability at 6 months. The preterm infants scored significantly lower in reactive trunk control at 8 months (Mann Whitney U = 102.0, p = 0.016) but this was the only difference noted. A significant developmental trend was shown in the static, active and reactive trunk control of the full-term infants (Chi-square = 81.4, 75.6 and 79.5 respectively, all p < 0.001. CONCLUSIONS The SATCo was reliable and responsive in assessing trunk control in young infants aged from 4 to 9 months. Care should be exercised when testing infants aged 5 to 6 months, who are more likely to use subtle hand support, and for those who have already achieved independent sitting. The SATCo could differentiate the reactive trunk control between the full-term and preterm infants at 8 months but not earlier. Psychometric properties of the SATCo in infants with motor disorders requires further investigation.

Abstract
The aim of the study is to select elements of motor skills assessed at 3 months that provide the best predictive properties for motor development at 9 months. In all children a physiotherapeutic assessment of the quantitative and qualitative development at the age of 3 months was performed in the prone and supine positions, which was presented in previous papers as the quantitative and qualitative assessment sheet of motor development. The neurological examination at the age of 9 months was based on the Denver Development Screening Test II and the evaluation of reflexes, muscle tone (hypotony and hypertony), and symmetry. The particular elements of motor performance assessment were shown to have distinct predictive value for further motor development (as assessed at 9 months), and the pelvis position was the strongest predictive element. Irrespective of the symptomatic and anamnestic factors the inappropriate motor performance may already be detected in the 3rd month of life and is predictive for further motor development. The assessment of the motor performance should be performed in both supine and prone positions. The proper position of pelvis summarizes the proper positioning of the whole spine and ensures proper further motor development. To our knowledge, the presented motor development assessment sheet allows the earliest prediction of motor disturbances.

Abstract
Aims The purpose of the study was to assess body posture asymmetries in the standing and sitting position in prematurely born children at six years of age. Study Design and Subjects We measured trunk symmetry in coronal plane. The study was carried out in a group of 101 children, aged 6-7 years, mean age of 6.63, including 50 preterm children born at gestational age <32 weeks (preterm group) and 51 full-term children (control group). Outcome Measures Trunk symmetry in coronal plane was measured using photogrammetric technique with Mora 4G CQ Elektronik. The subjects were examined in standing and sitting position. Statistical analyses were carried out using Shapiro-Wilk W-test, Student's t-test, Mann–Whitney U test, and Pearson's chi-squared test. Statistical significance was assumed at p < 0.05. Results No significant differences were found between the groups in the asymmetries identified in the relevant anthropometric points, relative to the position assumed during the examination or to the subjects' sex. Conclusions There are no significant differences in body posture in the coronal plane, between preterm children and full-term children. Premature birth does not have adverse effects related to body posture asymmetry in preterm children at the age of six.

Abstract
The aim of this study was to compare postural stability in a group of preterm-born children aged 4-6 years old and in a group of age-matched full-term control children by exploring both spatial and temporal analysis of the Center of Pressure (CoP). Twenty-nine children born prematurely (mean age: 5.38±0.17) and twenty-nine age-matched full-term control children participated in this study. Postural control was tested on both a stable and an unstable platform (from Framiral®) in three different visual conditions: eyes open fixating a target, eyes closed, and with vision perturbed by optokinetic stimulation. We observed a significant increase of both surface area and mean velocity of the CoP in pre-term children compared to full-term control children, particularly in an unstable postural condition. The spectral power indices increased significantly in pre-term children with respect to full-term control children, while the cancelling time was not different between the two groups of children tested. We suggested that poor postural stability observed in preterm children could be due to immaturity of the cortical processes (the occipital parietal prefrontal cortex) involved in motor control. Preterm children could have an inappropriate compensation of sensory inputs when they are tested in difficult postural and/or visual conditions.

Abstract
OBJECTIVE Premature newborns are considered at risk for motor development deficits, leading to the need for monitoring in early life. The aim of this study was to systematically review the literature about gross motor development of preterm infants, assessed by the Alberta Infant Motor Scale (AIMS) to identify the main outcomes in development. DATA SOURCE Systematic review of studies published from 2006 to 2015, indexed in Pubmed, Scielo, Lilacs, and Medline databases in English and Portuguese. The search strategy included the keywords: Alberta Infant Motor Scale, prematurity, preterm, motor development, postural control, and follow-up. DATA SUMMARY A total of 101 articles were identified and 23 were selected, according to the inclusion criteria. The ages of the children assessed in the studies varied, including the first 6 months up to 15 or 18 months of corrected age. The percentage variation in motor delay was identified in the motor outcome descriptions of ten studies, ranging from 4% to 53%, depending on the age when the infant was assessed. The studies show significant differences in the motor development of preterm and full-term infants, with a description of lower gross scores in the AIMS results of preterm infants. CONCLUSIONS It is essential that the follow-up services of at-risk infants have assessment strategies and monitoring of gross motor development of preterm infants; AIMS is an assessment tool indicated to identify atypical motor development in this population.

Abstract
UNLABELLED Studies suggest that both pre- and postnatal factors are predictors of age of attaining milestones in infancy. However, no studies evaluate the comparative strength of these predictors and the amount of the variance in development they explain. This study aimed to conduct a systematic evaluation of a broad selection of possible predictors of age at milestone attainment and to identify factors that explain significant inter-individual variance. Mothers of 5765 children of the Copenhagen Perinatal Cohort (1959-61) recorded 12 developmental milestones prospectively during the child's first year of life. Information on possible predictors was collected during pregnancy and at follow-up and was categorized into the domains: Family background, Pregnancy and delivery, Postnatal influences, and Postnatal growth. The domain Pregnancy and delivery contributed most of the explained variance in Overall mean of milestones (14.4%), with especially gestational age (β = -0.15; p ≤ 0.001) and birth weight (β = -0.16; p ≤ 0.001) being important predictors. CONCLUSION Several individual factors, especially gestational age, birth weight, breastfeeding, having lived in a full-time institution, and weight and head increase in the first year, were significantly associated with milestone attainment in the first year of life. Variables within the domain of Pregnancy and delivery explained the largest proportion of variance in milestone attainment compared to the other domains. What is known: • Younger age at attainment of motor developmental milestones positively predicts cognitive outcomes in adulthood. • Both pre- and postnatal factors have been associated with age of attaining milestones in infancy. What is new: • First study to provide a systematic evaluation of a broad selection of predictors of infant milestone attainment. • Variables within the domain of Pregnancy and delivery, especially gestational age and birth weight, explained the largest proportion of variance in milestone attainment. • The variance explained by the predictors decreased time-dependently with later milestones.

Abstract
BACKGROUND Infant developmental delays have been associated with several risk factors, such as familial environmental, individual and demographic characteristics. The goal of this study was to longitudinally investigate the effects of maternal knowledge and practices, home environment and biological factors on infant motor and cognitive outcomes. METHODS This was a prospective cohort study with a sample of 49 infants from Southern Brazil. The infants were assessed three times over 4 months using the Alberta Infant Motor Scale and the Bayley Scale of Infant Development (Mental Development Scale). Parents completed the Daily Activities Scale of Infants, the Affordances in The Home Environment for Motor Development - Infant Scale, the Knowledge of Infant Development Inventory and a demographic questionnaire. Generalized estimating equation with Bonferroni method as the follow-up test and Spearman correlation and multivariate linear backward regression were used. RESULTS Cognitive and motor scores were strongly associated longitudinally and increased over time. Associations between the home affordances, parental practices and knowledge, and motor and cognitive development over time were observed. This relationship explained more variability in motor and cognitive scores compared with biological factors. CONCLUSIONS Variability in motor and cognitive development is better explained by environment and parental knowledge and practice. The investigation of factors associated with infant development allows the identification of infants at risk and the implementation of educational programs and parental training to minimize the effects of developmental delay.

Abstract
AIMS We investigated whether spontaneous antigravity limbs movements in very low birth weight preterm infants were insufficient compared to those in term infants. The relationship between the quality of general movements (GMs) and antigravity limbs movements was also examined. METHODS Preterm infants with very low birth weight without central nervous system disorders nor severe respiration disorders, and healthy term infants were recruited. The infants were set in a supine position. The distance between both hands and between both feet, and the height of both hands and feet from the floor were recorded at 1-3 corrected months for preterm infants, and at 1-3 months for term infants by a 3D motion capture system. The measurements were adjusted for body proportions. GMs in preterm and term infants were assessed similarly. RESULTS Thirteen preterm and 15 term infants completed the study. In preterm infants, the distance between both hands and between both feet were longer, and the height of both hands and feet were lower than those in term infants in all measurements. In term infants, the height of both hands and feet increased as they developed, but no change was observed in preterm infants. In preterm infants with abnormal GMs, the distance between both hands was longer, and the height of both hands and feet was lower than that in those with normal GMs. There were no such differences between preterm infants with normal GMs and term infants with normal GMs. CONCLUSION Antigravity limbs movements in preterm infants within the first 3 month of corrected age were insufficient compared with those in term infants. Furthermore, no improvement with development was observed in preterm infants. In addition, preterm infants with abnormal GMs showed worse antigravity limbs movements than preterm and term infants with normal GMs. The preterm infants with normal GMs could behave similar to the full term infants.

Abstract
RESUMO Investigou-se longitudinalmente relações entre desenvolvimento motor e cognitivo, aspectos biológicos, práticas maternas, conhecimento parental e ambiente familiar de bebês. Participaram do estudo 49 bebês (3-16 meses) avaliados com a Alberta Infant Motor Scale e a Escala Mental da Bayley Scale of Infant Development. Os pais responderam o questionário sobre fatores biológicos, Daily Activities of Infant Scale, o Affordances no Ambiente Domiciliar para o Desenvolvimento Motor - Escala Bebê, e o Inventário sobre Conhecimento do Desenvolvimento Infantil. Avaliações foram conduzidas nas escolas ao longo de 4 meses. Foram utilizadas Equações de Estimativa Generalizada, teste de Bonferroni e coeficiente de correlação de Spearman. Observaram-se associações significativas na (1) análise univariada entre desenvolvimento motor e cognitivo e fatores ambientais (escolaridade, renda, disponibilidade de brinquedos, espaço físico, práticas e conhecimento parental, tempo de aleitamento e frequência na escola); (2) multivariada entre o desenvolvimento motor e renda, idade do pai e espaço físico da residência. Concluiu-se que os desenvolvimentos motores e cognitivos se mostraram interdependentes e fatores ambientais se mostraram mais significativos nas associações em detrimento dos biológicos, reforçando-se a importância do lar, do cuidado dos pais e das experiências que a criança vivencia ao longo dos primeiros anos de vida.

Abstract
Aim The primary aim of this study was to investigate the accuracy of the Alberta Infant Motor Scale (AIMS) and Neuro-Sensory Motor Developmental Assessment (NSMDA) over the first year of life for predicting motor impairment at 4 years in preterm children. The secondary aims were to assess the predictive value of serial assessments over the first year and when using a combination of these two assessment tools in follow-up. Method Children born <30 weeks’ gestation were prospectively recruited and assessed at 4, 8 and 12 months’ corrected age using the AIMS and NSMDA. At 4 years’ corrected age children were assessed for cerebral palsy (CP) and motor impairment using the Movement Assessment Battery for Children 2nd-edition (MABC-2). We calculated accuracy of the AIMS and NSMDA for predicting CP and MABC-2 scores ≤15th (at-risk of motor difficulty) and ≤5th centile (significant motor difficulty) for each test (AIMS and NSMDA) at 4, 8 and 12 months, for delay on one, two or all three of the time points over the first year, and finally for delay on both tests at each time point. Results Accuracy for predicting motor impairment was good for each test at each age, although false positives were common. Motor impairment on the MABC-2 (scores ≤5th and ≤15th) was most accurately predicted by the AIMS at 4 months, whereas CP was most accurately predicted by the NSMDA at 12 months. In regards to serial assessments, the likelihood ratio for motor impairment increased with the number of delayed assessments. When combining both the NSMDA and AIMS the best accuracy was achieved at 4 months, although results were similar at 8 and 12 months. Interpretation Motor development during the first year of life in preterm infants assessed with the AIMS and NSMDA is predictive of later motor impairment at preschool age. However, false positives are common and therefore it is beneficial to follow-up children at high risk of motor impairment at more than one time point, or to use a combination of assessment tools.

Abstract
The proposed assessment sheet aims to show in detail, which qualitative elements of motor performance are performed correctly in the 2nd month of life by children who in the 9th month reached the erect posture. Similar analysis was performed for the qualitative assessment in the 6th month. The prospective investigation of motor development involved a group of 109 children (40 girls and 69 boys). The study was based on the previously described quantity and quality assessment sheet of motor performance, validated for the 2nd and 6th month. Final investigation took place in the 9th month of life and was based on a neurological assessment. It could be shown that a completely correct assessment at the age of 2 months precludes future severe motor development disorders, especially cerebral palsy, although it does not rule out a slight delay. Prematurity and the analyzed risk factors, particularly IVH, impair the motor performance. The absence of axial symmetry, the shoulders protraction and improper position of the pelvis are the most important alarming features at the 2nd month. Distal elements observed in the prone position at the 6th month show a good prognosis for the motor performance in the 9th month. Any abnormalities, mainly related to the body axis and symmetry observed at 2 months of age should encourage one to put a child under observation.

Cabral TI, Pereira da Silva LG, Tudella E, Simões Martinez CM. Motor development and sensory processing: A comparative study between preterm and term infants. RESEARCH IN DEVELOPMENTAL DISABILITIES 2015; 36C:102-107. [PMID: 25462470 DOI: 10.1016/j.ridd.2014.09.018] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2014] [Revised: 09/21/2014] [Accepted: 09/23/2014] [Indexed: 06/04/2023]
Abstract
UNLABELLED Infants born preterm and/or with low birth weight may present a clinical condition of organic instability and usually face a long period of hospitalization in the Neonatal Intensive Care Units, being exposed to biopsychosocial risk factors to their development due to decreased spontaneous movement and excessive sensory stimuli. This study assumes that there are relationships between the integration of sensory information of preterm infants, motor development and their subsequent effects. OBJECTIVE To evaluate the sensory processing and motor development in preterm infants aged 4-6 months and compare performance data with their peers born at term. METHOD This was a cross-sectional and comparative study consisting of a group of preterm infants (n=15) and a group of term infants (n=15), assessed using the Test of Sensory Functions in Infants (TSFI) and the Alberta Infant Motor Scale (AIMS). RESULTS The results showed no significant association between motor performance on the AIMS scale (total score) and sensory processing in the TSFI (total score). However, all infants who scored abnormal in the total TSFI score, subdomain 1, and subdomain 5 presented motor performance at or below the 5th percentile on the AIMS scale. CONCLUSION Since all infants who presented definite alteration in tolerating tactile deep pressure and poor postural control are at risk of delayed gross motor development, there may be peculiarities not detected by the tests used that seem to establish some relationship between sensory processing and motor development.

Abstract
OBJECTIVE To determine whether premature infants' sleep organization, total sleep time, and arousals may be modulated while on a conformational positioner that provides boundaries, customized positioning, and containment compared with standard positioning (standard crib mattress). STUDY DESIGN A proof of concept trial using a within subject crossover design was conducted among 25 premature infants with feeding difficulties. Infants of 31.5 weeks gestational age served as their own control during overnight polysomnography at postconceptual age 38.4 weeks. Each baby received both interventions (order randomized), 1 for each one-half of the 10.5-hour study. RESULTS Use of the conformational positioner resulted in higher sleep efficiency of 61% vs 54% for the standard mattress (P < .05). The interventions did not differ for percent active sleep, percent quiet sleep, percent indeterminate sleep, or spontaneous arousals. Sleep efficiency was higher on the conformational positioner than standard positioning for surgical subjects and for subjects with necrotizing enterocolitis or gastroschisis (n = 10). The surgical subjects (n = 9) had lower sleep efficiency, lower percentage of active sleep, and more spontaneous arousals compared with the nonsurgical group. CONCLUSIONS The use of the conformational positioner improved sleep efficiency vs the standard mattress in premature infants with feeding difficulties. Infants requiring surgery or with gastrointestinal diagnoses may be more susceptible to environmental stress.

Abstract
OBJECTIVE To compare the motor development of infants from three population samples (Brazil, Canada and Greece), to investigate differences in the percentile curves of motor development in these samples, and to investigate the prevalence of motor delays in Brazilian children. METHODS Observational, descriptive and cross-sectional study with 795 Brazilian infants from zero to 18 months of age, assessed by the Alberta Infant Motor Scale (AIMS) at day care centers, nurseries, basic health units and at home. The Brazilian infants' motor scores were compared to the results of two population samples from Greece (424 infants) and Canada (2,400 infants). Descriptive statistics was used, with one-sample t-test and binomial tests, being significant p ≤ 0.05. RESULTS 65.4% of Brazilian children showed typical motor development, although with lower mean scores. In the beginning of the second year of life, the differences in the motor development among Brazilian, Canadian and Greek infants were milder; at 15 months of age, the motor development became similar in the three groups. A non-linear motor development trend was observed. CONCLUSIONS The lowest motor percentiles of the Brazilian sample emphasized the need for national norms in order to correctly categorize the infant motor development. The different ways of motor development may be a consequence of cultural differences in infant care.

Abstract
AIM Physical growth in neurologically healthy preterm infants affects motor development. This study investigated the separate relationships between muscle and fat in infancy and later motor development and physical growth. METHODS Muscle thickness and subcutaneous fat thickness of the anterior thigh were measured using ultrasound images obtained from neurologically healthy preterm infants at birth, 3, 6, 12 and 18 months' corrected age. We also obtained the Pediatric Evaluation of Disability Inventory and Alberta Infant Motor Scale scores at 18 months' corrected age to assess motor ability and motor delay. RESULTS Thirty preterm infants completed the study protocol. There was a significant positive correlation between motor ability and increments in subcutaneous fat thickness during the first 3 and 6 months' corrected age (r = 0.48 and 0.40, p < 0.05, respectively), but not between motor ability and muscle thickness growth in any of the periods. A secondary, logistic regression analysis showed that increments in subcutaneous fat thickness during the first 3 months were a protective factor for motor delay. CONCLUSION Subcutaneous fat accumulation in early infancy is more strongly associated with motor development and delay than muscle growth.

Abstract
OBJECTIVE. Our objective was to perform a meta-analysis to investigate whether low birthweight (LBW) or preterm birth was associated with difficulty in mental, neuromusculoskeletal, and movement-related school function tasks.
METHOD. Two search strategies produced 40 studies that met the inclusion criteria for the meta-analysis and yielded 549 effect sizes (d). Heterogeneity was evaluated by obtaining Q and I-squared values. Egger’s regression intercept test and a funnel plot were used to check for publication bias.
RESULTS. Children born LBW exhibited considerable difficulties in mental (d = −0.655, p < .0001) and neuromusculoskeletal and movement-related tasks (d = −0.391, p < .0001) compared with children of normal birthweight. Children born preterm also exhibited significant difficulties compared with full-term children in mental, neuromusculoskeletal, and movement-related tasks (d = −0.237, p < .0001).
CONCLUSION. Deficits in mental and motor functions in children born LBW or preterm appear to have significant effects on school readiness and academic achievement.

Abstract
Successful reaching requires postural control, either by active regulation or by postural support. The present paper reviews literature on typical and atypical development of reaching and postural control during infancy. Typically, reaching movements end in grasping around 4 months of age. Initially, reaches are characterized by large variation, including many trajectory corrections. During the first year, the movements get increasingly straight and smooth. Reaching in low-risk preterm infants is initially characterized by advanced development, but minor impairments may emerge in the second half of infancy. In high-risk preterm infants, development of reaching is characterized by delay and non-optimal reaching performance. Typical development of postural adjustments is characterized by variation and an increasing ability to adapt the variable repertoire to the specifics of the situation. The latter is facilitated by an increasing role of anticipatory mechanisms in the second half of infancy. Atypically developing infants may have a reduced repertoire and usually have difficulties in adapting postural adjustments. In infancy, most reaching movements are performed during sitting. The postural challenge of sitting may interfere in particular with the development of reaching in atypically developing infants. The practical implications of this suggestion are discussed.

Abstract
BACKGROUND Infants with very low birth weight (VLBW) are at increased risk for motor deficits, which may be reduced by early intervention programs. For detection of motor deficits and to monitor intervention, different assessment tools are available. It is important to choose tools that are sensitive to evaluate the efficacy of intervention on motor outcome. OBJECTIVE The purpose of this study was to compare the Alberta Infant Motor Scale (AIMS) and the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development-Dutch Second Edition (BSID-II-NL) in their ability to evaluate effects of an early intervention, provided by pediatric physical therapists, on motor development in infants with VLBW at 12 months corrected age (CA). DESIGN This was a secondary study in which data collected from a randomized controlled trial (RCT) were used. METHODS At 12 months CA, 116 of 176 infants with VLBW participating in an RCT on the effect of the Infant Behavioral Assessment and Intervention Program were assessed with both the AIMS and the PDI. Intervention effects on the AIMS and PDI were compared. RESULTS Corrected for baseline differences, significant intervention effects were found for AIMS and PDI scores. The highest effect size was for the AIMS subscale sit. A significant reduction of abnormal motor development in the intervention group was found only with the AIMS. LIMITATIONS No Dutch norms are available for the AIMS. CONCLUSIONS The responsiveness of the AIMS to detect intervention effects was better than that of the PDI. Therefore, caution is recommended in monitoring infants with VLBW only with the PDI, and the use of both the AIMS and the Bayley Scales of Infant Development is advised when evaluating intervention effects on motor development at 12 months CA.

Abstract
BACKGROUND One objective of a neonatal follow-up program is to examine and predict gross motor outcome of infants born preterm. AIMS To assess the concurrent validity of the Test of Infant Motor Performance (TIMP) and the Alberta Infant Motor Scale (AIMS), the ability to predict gross motor outcome around 15 months corrected age (CA), and to explore factors associated with the age of independent walking. METHODS 95 infants, born at a gestational age <30 weeks, were assessed around 3, 6 and 15 months CA. At 3 months CA, correlations of raw-scores, Z-scores, and diagnostic agreement between TIMP and AIMS were determined. AIMS-score at 15 months CA and parental-reported walking age were outcome measures for regression analyses. RESULTS The correlation between TIMP and AIMS raw-scores was 0.82, and between Z-scores 0.71. A cut-off Z-score of -1.0 on the TIMP had 92% diagnostic agreement (κ = 0.67) with an AIMS-score < P10. Neither TIMP- nor AIMS-scores at 3 months CA were associated with the gross motor outcome at 15 months CA. The AIMS-scores at 6 months CA predicted the AIMS-scores at 15 months CA with an explained variance of 19%. Median walking age was 15.7 months CA, with which only the hazard ratio of the AIMS at 6 months CA and ethnicity were significantly associated. CONCLUSIONS Prediction of gross motor development at 15 months CA and independent walking was not possible prior to 6 months CA using the AIMS, with restricted predictive value. Cultural and infant factors seem to influence the onset of independent walking.

Abstract
BACKGROUND The Alberta Infant Motor Scale (AIMS) is a well-known motor assessment tool used to identify potential delays in infants' motor development. Although Brazilian researchers and practitioners have used the AIMS in laboratories and clinical settings, its translation to Portuguese and validation for the Brazilian population is yet to be investigated. OBJECTIVE This study aimed to translate and validate all AIMS items with respect to internal consistency and content, criterion, and construct validity. DESIGN A cross-sectional and longitudinal design was used. METHODS A cross-cultural translation was used to generate a Brazilian-Portuguese version of the AIMS. In addition, a validation process was conducted involving 22 professionals and 766 Brazilian infants (aged 0-18 months). RESULTS The results demonstrated language clarity and internal consistency for the motor criteria (motor development score, α=.90; prone, α=.85; supine, α=.92; sitting, α=.84; and standing, α=.86). The analysis also revealed high discriminative power to identify typical and atypical development (motor development score, P<.001; percentile, P=.04; classification criterion, χ(2)=6.03; P=.05). Temporal stability (P=.07) (rho=.85, P<.001) was observed, and predictive power (P<.001) was limited to the group of infants aged from 3 months to 9 months. LIMITATIONS Limited predictive validity was observed, which may have been due to the restricted time that the groups were followed longitudinally. CONCLUSIONS In sum, the translated version of AIMS presented adequate validity and reliability.

Abstract
BACKGROUND The present study reports the development and application of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS), a parental self-report designed to assess the quantity and quality of affordances in the home environment that are conducive to motor development for infants aged 3-18 months. METHODS Steps in its development included use of expert feedback, establishment of construct validity, interrater and intrarater reliability, and predictive validity. With all phases of the project, 113 homes were involved. RESULTS Intraclass correlation coefficients for interrater and intrarater reliability for the total score were 1 and 0.94, respectively. In addition, results indicate that the test has the characteristic of differentiating a wide range of scores. Regression analysis for the AHEMD-IS and motor development using the Alberta Infant Motor Scale supports preliminary evidence for predictive validity. CONCLUSION Our findings suggest that the AHEMD-IS has sufficient reliability and validity as an instrument for assessing affordances in the home environment, with clinical and research applications.

Abstract
AIM To trace a reference curve for motor development from birth up to 12 months of corrected chronological age in infants born preterm and low birth weight. METHODS This is a cross-sectional study with a sample of 308 preterm infants (53% boys) weighing < 2500 g at birth. The Alberta Infant Motor Scale (AIMS) was used for motor development assessment. RESULTS Comparing the motor performance of preterm infants with infants from a standardized sample on the AIMS, it was found that, except for the age group of the newborn, preterm infants showed lower motor development scores in comparison with the AIMS normative sample in all age groups between 1 and 12 months. The curve of motor development showed a continuous increase in the number of motor skills of preterm infants during their first 12 months of age. However, the average of motor acquisitions of preterm infants showed a nonlinear pattern with a standard indicator of stabilization between 8 and 10 months of age. CONCLUSION Preterm infants, 1-12 months of age, showed motor development AIMS scores lower than the standards established in the normative sample. The findings may contribute as norm-reference for assessing the motor development of preterm infants in follow-up programmes in developing countries.

Abstract
BACKGROUND Preterm infants are recognised as developing at a significantly slower rate than their full-term peers and with different movement quality. AIM This study aimed to describe the longitudinal gross motor trajectories of these infants in the first 18 months of (corrected) age and investigate factors associated with gross motor development. STUDY DESIGN A longitudinal study was conducted with convenience samples of 58 preterm infants born < or = 29 weeks of gestation and 52 control full-term infants in Australia. OUTCOME MEASURES The infants were assessed at 4, 8, 12 and 18 months of (corrected) age using the Alberta Infant Motor Scale (AIMS). RESULTS Forty-six preterm and 48 control infants completed all four assessments. The preterm group scored significantly lower on various sub-scores at all age levels. Almost half of the preterm infants demonstrated less progression in the sit sub-scale from 4 to 8 months (corrected) age, possibly due to an imbalance between flexor and extensor strength in the trunk. At 12 and 18 months of (corrected) age, lack of rotation and fluency in their movements were evident in some preterm infants. Presence of intra-ventricular haemorrhage and chronic lung disease were associated with poor motor performance at 4 months and use of postnatal steroids was associated with poor motor performance at 4, 8 and 18 months of corrected age. CONCLUSION The imbalance between flexor and extensor muscle strength in preterm infants had a stronger impact on motor development than usually expected. The AIMS appears to be a sensitive assessment tool to demonstrate the unique movement characteristics in this preterm cohort.

Abstract
BACKGROUND The Alberta Infant Motor Scale (AIMS) is a norm-referenced test that assesses the spontaneous motor performance of infants from birth through independent walking (0-18 months). This scale has been utilized for clinical and research purposes in various countries, however, whether the initial standardization in Canadian infants is also representative of other countries' populations has been questioned. AIM To assess whether the AIMS needs new reference values for Greek infants. METHODS A cohort of 424 healthy full-term infants (250 boys and 174 girls), aged between 7 days and 18 months, derived from various areas of the Prefecture of Attica and from all socio-economic classes to ensure a true representation, was studied. The AIMS-scores of Greek infants were compared with the norm-referenced values of the original Canadian population reported by Piper and Darrah. RESULTS The mean AIMS-scores did not differ significantly between Greek and Canadian infants at any age level from birth to 18 months, except for the 2-<3 month of age when higher scores were observed in Greek infants (p=0.02). There was no significant difference in AIMS-values corresponding to the 5th and 90th percentile between Greek and Canadian infants. Inter-rater reliability was excellent in our study population [ICC: 0.99 (95% CI: 0.99-0.99)]. CONCLUSION In healthy full-term Greek infants, gross motor maturity assessed by the AIMS during the first 18 months of age, seems to follow a similar course to that of Canadian infants.

Abstract
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, and 18 months corrected age (CA). RESULTS Intrarater reliability was high (intraclass correlation coefficient [ICC] > or =0.99). The ICC for interrater reliability varied from 0.85 to 0.97. The ICC was low at 4 and 18 months CA. CONCLUSIONS The AIMS is reliable in evaluating motor development in infants born preterm. Clinicians should be cautious about using the AIMS in infants at very young ages and those approaching independent ambulation. Accurate placement of the window on a movement repertoire is crucial. Attention is required when using the AIMS in infants developing atypically.
