To evaluate whether infants with complex congenital heart disease (CCHD) have an increased risk of impaired quality of motor behavior and delayed motor milestones.A cohort of 69 infants with CCHD (43 males, 26 females) were assessed with the Infant Motor Profile (IMP) at three time periods between 6 to 18 months, mean ages in months (SD): 6.4 (0.7); 12.7 (1.0); 18.5 (0.7) IMP data were available from a reference sample of 300 Dutch infants. Analyses included multivariable logistic regression analysis to estimate differences in IMP scores below the 15th centile between children with CCHD and the reference group, and linear mixed-effects models to assess the effect of ventricular physiology and systemic oxygen saturation (SpO2) of less than 90% on IMP outcomes.Infants with CCHD had increased risks of total IMP scores below the 15th centile (lowest odds ratio [OR] at 18mo: 6.82 [95% confidence interval {CI} 2.87-16.19]), especially because of lower scores in the domains of variation, adaptability, and performance. Children with single ventricle CCHD scored consistently 3.03% (95% CI 1.00-5.07) lower than those with two ventricle physiology, mainly from contributions of the variation and performance domains. SpO2 of less than 90% was associated with 2.52% (95% CI 0.49-4.54) lower IMP scores.CCHD, especially single ventricle physiology, increases risk of impaired motor development.Complex congenital heart disease (CCHD) substantially increases risk of impaired motor development. CCHD is associated with motor delay and reduced motor variation and adaptability. Single ventricle physiology increases the risk of impaired motor behavior.

Aim To perform a scoping literature review of associations between risk factors in early life and developmental coordination disorder (DCD). Method PubMed, Embase, CINAHL, PsycINFO, and Web of Science (January 1994–March 2019) were searched to identify studies on early risk factors and motor impairment or DCD. The effect of single and multiple risk factors was assessed. Level of evidence was evaluated following the Centre for Evidence‐Based Medicine guidelines. Meta‐analysis on the effect of preterm birth was performed. Results Thirty‐six studies fulfilled inclusion criteria; 35 had evidence level 3, one had level 4. Highest evidence was available that preterm birth and male sex in term‐born children were associated with DCD. The odds ratio of preterm birth was 2.02 (95% confidence interval: 1.43–2.85). Low to moderate evidence was available that parental subfertility, maternal smoking during pregnancy, postnatal corticosteroid treatment in infants born preterm, extra corporeal membrane oxygenation, retinopathy of prematurity, abnormalities on magnetic resonance imaging scans at term age, and accumulating perinatal or neonatal risk factors were associated with motor impairment. Interpretation Limited information on early risk factors of DCD is available. Only preterm birth and male sex were consistently associated with an increased risk of DCD. What this paper adds Preterm birth is a risk factor for developmental coordination disorder (DCD).In term‐born children, male sex was consistently associated with DCD.Risk factors for DCD are similar to risk factors for cerebral palsy., What this paper adds Preterm birth is a risk factor for developmental coordination disorder (DCD).In term‐born children, male sex was consistently associated with DCD.Risk factors for DCD are similar to risk factors for cerebral palsy.

Aim To determine the prevalence of atypical general movements (GMs) in the general population, to examine its time trend and associated factors.Methods Participants consisted of 300 infants born in 2016-2018 (current cohort; gestational age 39.4 weeks (27-42); 162 boys), representative of the Dutch population. GMs were assessed at 2-4 months corrected age in terms of GM-complexity (definitely abnormal (DA) or not) and fidgety movements (present or absent). GM-complexity data from a cohort of 455 Dutch infants born in 2001-2002 were used to investigate the time trend.Results In the current cohort, 10 infants (3%) showed DA GM-complexity and 8 (3%) absent fidgety movements. Only one infant had both GM-impairments (0.3%). The prevalence of DA GM-complexity did not differ from that in the 2001-2002 cohort (adjusted odds ratio (OR) = 1.47 [0.53, 4.06]). DA GM-complexity was associated with maternal smoking (adjusted OR = 3.59 [1.56, 8.28]) and marginally with prematurity (adjusted OR = 2.78 [1.00, 7.74]); absence of fidgety movements was curvilinearly associated with assessment age only (OR = 1.06 [1.01, 1.12]).Conclusion In the general population, the prevalence of DA GM-complexity and absent fidgety movements is 3%. The finding that they rarely co-occur and are associated with different factors indicates that GM-assessment needs to address both aspects.

To evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24-42 months: group 1 with previous frequent tablet-use exposure (n = 26), group 2 without previous tablet-use exposure (n = 52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p = 0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience.

Aim: To determine the prevalence of prevailing head position to one side (PHP) in young infants and to evaluate its associations with reaching performance, neurological condition and perinatal and socio-economic factors. Methods: Observational study in 500 infants (273 boys) 2-6 months corrected age, representative of the Dutch population (median gestational age 39.7 weeks (27-42); birthweight 3438 g (1120-4950). Prevailing head position to one side and reaching performance were assessed with the Infant Motor Profile; neurological condition with the Standardized Infant NeuroDevelopmental Assessment. Socio-economic information and perinatal information were obtained by questionnaire and medical records. Associations were analysed with uni- and multivariable statistics. Results: Prevailing head position to one side was observed in 100 infants (20%), and its prevalence decreased from 49% at 2 months to 0% at 6 months. Only in infants aged 4-5 months PHP was significantly associated with worse reaching and an at-risk neurological score. Prevailing head position to one side was weakly associated with prenatal substance exposure, post-natal admission to a paediatric ward and paternal native Dutch background. Conclusion: Prevailing head position to one side at 2-3 months is a frequently occurring sign with limited clinical significance. Yet, PHP at 4-5 months is associated with a worse functional and neurological condition. Therefore, PHP at 4-5 months could serve as a red flag indicating possible challenges in later development.

BACKGROUND: Caregivers' experiences during early intervention of their infant with special needs have consequences for their participation in the intervention. Hence, it is vital to understand caregivers' view. This study explored caregivers' experiences with the family-centred early intervention programme 'COPing with and CAring for infants with special needs' (COPCA).METHODS: The data of this qualitative study were collected after 6 months of COPCA intervention in 15 families with an infant with special needs. COPCA was delivered by paediatric physiotherapists in training to become COPCA-coaches. Caregivers filled out a study-specific questionnaire with three open-ended questions addressing 1) their overall experience with COPCA, 2) what aspects of COPCA they had experienced as important, and 3) what they had learned during the intervention process. The answers were analysed using the content analysis approach of Graneheim and Lundman (2004).RESULTS: Respondents were mothers. Interrater reliability of the content analyses of the three questions was twice excellent (κ=0.95, κ=0.92) and once good (κ=0.77). The content analysis of the first question resulted in four categories and three sub-categories e.g., evaluation of COPCA as a form of intervention, benefit from COPCA. The content analyses of the second question resulted in eight categories, e.g., home-based intervention, support from the therapist and the attainment of competences. The content analyses of the third question generated seven categories and four sub-categories e.g., to support the infant autonomously at home, to recognise the competences of the infant, caregiver confidence and relationship with the infant.CONCLUSIONS: The participating mothers appreciated the COPCA early intervention programme. They especially valued its home-based setting, the support from the coach, and the experience being able to participate as active partners in the intervention make their own decisions. This means that the mothers valued the family-centred, ecological and relationship-based elements of early intervention that currently are recommended.

AIM: We compared the impact of standard infant physiotherapy and the family-centred programme, Coping With and Caring for Infants with Special Needs (COPCA), in infants born before 32 weeks without significant brain lesions.METHODS: This randomised controlled trial was carried out in patients' homes and outpatient settings in Switzerland between January 2016 and October 2019. We used data from the national SwissNeoNet register and an assessment battery that included infant and family outcomes and video analyses of therapy sessions. The Infant Motor Profile was the primary outcome instrument.RESULTS: The COPCA group comprised six boys and two girls with a median gestational age of 27 weeks (range 25-30) and the standard care group comprised seven boys and one girl with a median gestational age of 29.5 weeks (range 26-31). COPCA participants improved significantly more between baseline and 18 months in the IMP variation (9.0 percentage points, 95% confidence interval 0.3-17.5) and performance (12.0 percentage points, 95% confidence interval 4.1-20.6) domains than standard care participants. COPCA coaching was positively associated with IMP scores at 18 months, but some standard care actions were negatively associated.CONCLUSION: COPCA was associated with better motor outcome in infants born before 32 weeks than standard infant physiotherapy.

To study changes in muscular postural strategies and general motor behaviour during the transition to independent walking. Postural control was assessed at its two functional levels: (1) direction specificity, in which dorsal muscles are primarily activated when reaching forward; and (2) fine-tuning of direction specificity.In an explorative longitudinal study, surface electromyograms of the arm, trunk, and neck muscles of 28 typically developing infants were recorded during reaching while sitting. Each infant was assessed in three developmental phases: during pull-to-stand (T0), first independent steps (T1), and 1 month after T1 (T2). Motor behaviour was assessed using the Infant Motor Profile (IMP). The effect on developmental outcome measures (postural parameters and IMP) of the developmental phases (T0, T1, T2) was estimated using linear mixed-effects models.None of the postural parameters changed significantly over time. However, individual developmental trajectories showed infant-specific postural reorganizational changes. Total IMP score decreased between T0 and T1 (mean IMP score 95% and 91% respectively; p0.001); between T1 and T2 IMP scores did not change (91% and 93%; p=0.073).Typically developing infants do not show consistent patterns of postural reorganization but show individual muscular strategies during the transition to independent walking. However, signs of reorganization of general motor behaviour are present.Infants show signs of reorganization of motor behaviour when learning to walk. Infants show individual strategies of postural reorganization when learning to walk.CONTROL POSTURAL DEL TRONCO EN LA SEDESTACIÓN Y COMPORTAMIENTO MOTOR GENERAL DURANTE EL APRENDIZAJE DE MARCHA: OBJETIVO: Estudiar los cambios en las estrategias posturales musculares y el comportamiento general motor en la transición a la marcha independiente. El control postural fue evaluado en dos niveles funcionales: 1) especificidad de dirección, en el cual los músculos dorsales son primariamente activados al inclinarse hacia adelante; y 2) y ajuste en la dirección específica.En un estudio longitudinal exploratorio, electromiogramas de superficie en los músculos de los miembros superiores, tronco, y cuello de 28 niños con desarrollo típico fue registrado durante el control postural, específicamente durante el alcance mientras estaban sentados. A su vez, cada niño fue evaluado en tres fases del desarrollo: durante la tracción para pararse (T0); primeros pasos independientes (T1) y 1 mes después de T1 (T2). El comportamiento motor se evaluó utilizando el perfil motor infantil (Infant Motor Profile [IMP]). El efecto sobre las medidas de resultado del desarrollo (parámetros posturales y IMP) de las fases de desarrollo (T0, T1, T2) se estimó utilizando modelos lineales de efectos mixtos.Ninguno de los parámetros posturales cambiaron significativamente en el tiempo. Sin embargo, las trayectorias del desarrollo individual mostraron cambios en la reorganización postural de algunos niños. El total de los valores de IMP disminuyeron entre T0 y T1 (media de valores de IMP 95% y 91% respectivamente; p0.001); entre T1 y T2 no hubo cambios de IMP (91% y 93%; p=0.073).Los niños con desarrollo típico no mostraron patrones consistentes de reorganización postural, pero mostraron estrategias musculares individuales durante la transición hacia la marcha independiente. Sin embargo, se vieron signos de reorganización en el comportamiento motor general.CONTROLE POSTURAL DURANTE O ALCANCE NA POSTURA SENTADA E COMPORTAMENTO MOTOR GERAL AO APRENDER A ANDAR: OBJETIVO: Estudar mudanças nas estratégias de músculos posturais e comportamento motor geral durante a transição para a marcha independente. O controle postural foi avaliado em dois níveis funcionais: (1) especificidade direcional, em que os músculos dorsais são ativados primariamente durante o alcance anterior; e 2) refinamento da especificidade direcional. MÉTODO: Em um estudo exploratório longitudinal, eletromiogramas de músculos do braço, tronco e pescoço de 28 lactentes com desenvolvimento típico foram registrados durante o alcance na postura sentada. Cada lactente foi avaliado em três fases do desenvolvimento: durante o segurar-se para levantar (T0), primeiros passos independentes (T1) e um mês após T1 (T2). O comportamento motor foi avaliado usando o Perfil Motor infantil (IMP). O efeito das fases do desenvolvimento (T0, T1 e T2) sobre as medidas de desfecho do desenvolvimento (parâmetros posturais e IMP) foi estimado usando modelos lineares de efeitos mistos. RESULTADOS: Nenhum dos parâmetros posturais mudou significativamente com o tempo. No entanto, as trajetórias desenvolvimentais individuais mostraram mudanças posturais reorganizacionais lactente-específicas. O escore IMP total diminuiu entre T0 e T1 (escore médio IMP 95% e 91% respectivamente; p0,001); entre T1 e T2 os escores IMP não mudaram (91% e 93%; p=0,073). INTERPRETAÇÃO: Lactentes com desenvolvimento típico não mostraram padrões consistentes de reorganização postural, mas mostrarm estratégias musculares individuais durante a transição para a marcha independente. No entanto, sinais de reorganização do padrão motor geral estão presentes.

Purpose: To investigate postural effects of the family-centered program, COPing with and CAring for infants with special needs (COPCA), applied at 3 to 6 months' corrected age in infants at high risk of cerebral palsy. Previously, we reported postural differences between the infants at risk of CP in the control group of the current study and a group of infants developing typically. Now we focus on differences between 2 intervention groups.Methods: We explored postural adjustments during reaching in seated infants at 4, 6, and 18 months using surface electromyography of arm, neck, and trunk muscles. Infants randomly received the family-centered program or another infant physical therapy. Using videotaped intervention sessions, we investigated correlations between time spent on specific physical therapeutic actions and direction specificity, recruitment order, and anticipatory activation at 18 months.Results: Postural adjustments in both groups were similar, but development of direction specificity and anticipatory activation in COPCA infants better mimicked typical development. These 2 parameters were associated with COPCA-type physical therapeutic actions.Conclusions: Postural control was similar after both interventions. Positive outcomes were associated with fewer intervening actions of the therapist and greater allowance of spontaneous movements.

Asthma is a chronic reversible obstructive airway disease, which is common among children and leads to respiratory impairment. Studies showed that asthma is more common among children born after in vitro fertilization (IVF) than among spontaneously conceived children. However, it is unknown which component of the IVF procedure contributes to this putative link. Therefore, the aim of this prospective follow-up study was to differentiate the possible effect of ovarian hyperstimulation from that of the in vitro culture procedure on asthma and rhinitis in 9-year-old children conceived with IVF. The study comprised three groups of singletons: (I) conceived with ovarian hyperstimulation-IVF (COH-IVF, n = 95); (II) conceived with modified natural cycle-IVF (MNC-IVF, n = 48); and (III) naturally conceived to subfertile couples (Sub-NC, n = 68). Parents filled out the validated Dutch version of the asthma questionnaire of the International Study of Asthma and Allergies. Asthma prevalence in the groups did not differ: COH-IVF n = 8 (8%); MNC-IVF n = 0 (0%); and Sub-NC n = 4 (6%). Adjustment for confounders did not alter the results. Conclusion: Neither ovarian hyperstimulation nor the in vitro culture procedure was associated with asthma and rhinitis at 9 years. IVF children had a similar prevalence of asthma compared with children conceived naturally by subfertile couples. Trial registration: ISRCTN76355836 What is Known: • An increased risk for asthma has been observed in children born after in vitro fertilization at preschool and school age.• The association between IVF and asthma may be partly explained by parental subfertility. What is New: • IVF children do not have a higher prevalence of asthma than children of subfertile couples conceived naturally.• Ovarian hyperstimulation used in IVF is not associated with asthma in 9-year-old children of subfertile couples.

BACKGROUND: Muscle tone is an indispensable element in motor development. Its assessment forms an integral part of the infant neurological examination. Knowledge on the prevalence of atypical tone in infancy is lacking.AIM: To assess the prevalence of atypical muscle tone in infancy and of the most common atypical muscle tone patterns, and associations between atypical tone and perinatal risk and neurodevelopmental status.STUDY DESIGN: Cross-sectional study.SUBJECTS: 1100 infants (585 boys; gestational age 39.4 weeks (27.3-42.4)), 6 weeks-12 months corrected age, representative of the Dutch population.OUTCOME MEASURES: Muscle tone and neurodevelopmental status were assessed with the Standardized Infant NeuroDevelopmental Assessment (SINDA). Perinatal information was obtained by questionnaire and medical records. Univariable and multivariable statistics were applied.RESULTS: Ninety-two infants (8%) had atypical muscle tone in 3-4 body parts (impaired pattern), while atypical muscle tone in 1-2 body parts was observed in 50%. Isolated leg hypotonia and isolated arm hypertonia were most common. Isolated arm hypertonia and the impaired pattern were most clearly but only moderately associated with perinatal risk. These patterns were also most clearly associated with lower neurological scores. Only the impaired pattern was associated with lower developmental scores.CONCLUSION: Atypical muscle tone in one or two body parts is common in infancy and has in general little clinical significance. This finding corresponds to the well-known high prevalence of a typical but non-optimal neurological condition. Eight percent of infants show atypical muscle tone in 3-4 body parts. This clinically relevant pattern is associated with perinatal risk and less favourable neurodevelopmental status.

Background: The Alberta Infant Motor Scale (AIMS) has been developed in Canada in the 90ies. The AIMS and its Canadian norms are frequently used across the world to monitor infants' gross motor development. Currently, it is disputed whether the Canadian norms are valid for non-Canadian infants.Aims: To compare scores on the AIMS of Dutch infants with that of the Canadian norms, to compare the sequence of motor milestones in Dutch and Canadian infants, and to establish Dutch AIMS norms.Study design: Cross-sectional study.Subjects: 1697 infants, aged 2-18 months, representative of the Dutch population (gestational age 39.7 weeks (27-42)).Outcome measure.AIMS assessments, based on standardized video. Perinatal and social information was obtained by questionnaire and medical records. To create Dutch reference values quantile regression with polynomial splines was used.Results: 1236 Dutch infants (73%) scored below the 50th (P50) percentile of the Canadian norms, 653 (38%) below the P10 and 469 (28%) below the P5. In infants aged 6 to 12 months these values were: 567 infants (81%) Conclusions and implications: Gross motor development of Dutch infants is considerably slower than that of the Canadian AIMS norms sample. To prevent overdiagnosis of developmental delay and overreferral to paediatric physiotherapy Dutch AIMS norms are required. The paper introduces these norms, including percentile ranks.

AIM: To evaluate the associations between motor development in infancy and developmental outcomes at school age.METHOD: Participants were 195 children (99 males, 96 females; mean age [SD] 9y 3mo [3mo], range 8y 4mo-10y 11mo) born to couples whose reduced fertility was or was not treated with assisted reproductive technologies. Motor behaviour was assessed at 4, 10, and 18 months with the Infant Motor Profile (IMP). IQ, neurological optimality score (NOS), and behavioural problem scores were measured at 9 years with the Wechsler Abbreviated Scale of Intelligence, minor neurological dysfunction assessment, and the Child Behavior Checklist respectively.RESULTS: Children with a slow developmental trajectory in the IMP-domain adaptability had an IQ 12.6 points lower (95% confidence interval [CI] 4.7-20.4) and an NOS 3.4 points lower (95% CI 0.7-6.2) at 9 years of age than children with typical adaptability development. Children with a slow developmental trajectory in the IMP-domain performance had an IQ 5.0 points lower (95% CI 0.7-9.3) than children with typical performance development. A non-optimal trajectory in IMP-variation and a fluctuating trajectory in IMP-fluency were associated with higher internalizing scores of 3.6 and 5.8 points respectively, than infants with optimal IMP-domain trajectories.INTERPRETATION: In relatively low-risk children, motor behaviour in infancy was associated with neurological, cognitive, and behavioural function at school age.

Aim: To explore intra-rater and inter-rater reliability of the Infant Motor Profile (IMP). The IMP is a video-based method assessing movement quality (movement variation, adaptability, symmetry and fluency) and motor skills in infants aged 3 to 18 months. Method: The IMP assessment was performed on 50 infants aged 3 to 12 months recruited in connection with health control in primary health care, mean gestational age at birth 39.4 weeks, mean birthweight 3462 g. Seven infants had a moderately increased risk of developmental disorders. Three pediatric physiotherapists performed independent rating of the video recordings. One rater assessed the video recordings twice with a four-week interval. Results: Intraclass correlation coefficient (ICC) for intra-rater reliability was found satisfactory for the total IMP score (ICC = 0.95), and the domains: performance (ICC = 0.98), variation (ICC = 0.74), adaptability (ICC = 0.93) and fluency (ICC = 0.86). The ICC value for symmetry was 0.65. For inter-rater reliability, ICC values were satisfactory for the total IMP score (ICC = 0.86-0.91), and the domains: performance (ICC = 0.98), variation (ICC = 0.71-0.82), adaptability (ICC = 0.99) and fluency (ICC = 0.82-0.81). The ICC values for symmetry varied between 0.13-0.35. Conclusion: In this sample, including mostly low-risk infants, satisfactory intra- and inter-rater reliability for all domains were demonstrated, except for symmetry.

International audience; Background: General Movement Assessment (GMA) is a powerful tool to predict Cerebral Palsy (CP). Yet, GMA requires substantial training challenging its broad implementation in clinical routine. This inspired a world-wide quest for automated GMA. Aim: To test whether a low-cost, marker-less system for three-dimensional motion capture from RGB depth sequences using a whole body infant model may serve as the basis for automated GMA.Study design: Clinical case study at an academic neurodevelopmental outpatient clinic.Subjects: Twenty-nine high risk infants were assessed at their clinical follow-up at 2-4 month corrected age (CA). Their neurodevelopmental outcome was assessed regularly up to 12-31 months CA.Outcome measures: GMA according to Hadders-Algra by a masked GMA-expert of conventional and computed 3D body model (“SMIL motion”) videos of the same GMs. Agreement between both GMAs was tested using dichotomous and graded scaling with Kappa and intraclass correlations, respectively. Sensitivity and specificity to predict CP at ≥12 months CA were assessed.Results: Agreement ofthe two GMA ratings was moderate-good for GM-complexity (κ=0.58; ICC=0.874 [95%CI 0.730;0.941]) and substantial-good for fidgety movements (FMs; Kappa=0.78, ICC=0.926[95%CI 0.843;0.965]). Five children were diagnosed with CP (four bilateral, one unilateral CP). The GMs of the child with unilateral CP were twice rated as mildly abnormal with FMs. GM-complexity and somewhat less FMs, of both conventional and SMIL motion videos predicted bilateral CP comparablyto published literature.Conclusions: Our computed infant 3D full body model is an attractive starting point for automated GMA in infants at risk of CP.

Aim To assess reliability and predictive validity of the neurological scale of the Standardized Infant NeuroDevelopmental Assessment (SINDA), a recently developed assessment for infants aged 6 weeks to 12 months. Method To assess reliability, three assessors independently rated video‐recorded neurological assessments of 24 infants twice. Item difficulty and discrimination were determined. To evaluate predictive validity, 181 infants (median gestational age 30wks [range 22–41wks]; 92 males, 89 females) attending a non‐academic outpatient clinic were assessed with SINDA's neurological scale (28 dichotomized items). Atypical neurodevelopmental outcome at 24 months or older corrected age implied a Bayley Mental Developmental Index or Psychomotor Developmental Index lower than 70 or a diagnosis of cerebral palsy (CP). Predictive values were calculated from SINDA (2–12mo corrected age, median 3mo) and typical versus atypical outcome. Results Intraclass correlation coefficients of intrarater and interrater agreement of the neurological score varied between 0.923 and 0.965. Item difficulty and discrimination were satisfactory. At 24 months or older, 56 children (31%) had an atypical outcome (29 had CP). Atypical neurological scores (below 25th centile, ≤21) predicted atypical outcome and CP with sensitivities of 89% and 100%, and specificities of 94% and 81% respectively. Interpretation SINDA's neurological scale is reliable and in a non‐academic outpatient setting has a satisfactory predictive validity for atypical developmental outcome, including CP, at 24 months or older. What this paper adds The Standardized Infant NeuroDevelopmental Assessment's neurological scale has a good to excellent reliability.The scale has promising predictive validity for cerebral palsy.The scale has promising predictive validity for other types of atypical developmental outcome., What this paper adds The Standardized Infant NeuroDevelopmental Assessment's neurological scale has a good to excellent reliability.The scale has promising predictive validity for cerebral palsy.The scale has promising predictive validity for other types of atypical developmental outcome.

STUDY QUESTION: Does Day-3 cleavage-stage PGS affect neurodevelopment of 9-year-old IVF offspring?SUMMARY ANSWER: We did not find evidence of adverse consequences of Day-3 cleavage-stage PGS on neurodevelopment of 9-year-old IVF offspring, although children born after IVF with or without PGS often had a non-optimal neurological condition.WHAT IS KNOWN ALREADY: Knowledge on long-term sequelae for development and health of children born following PGS is lacking. This is striking as evidence accumulates that IVF itself is associated with increased risk for impaired health and development in the offspring.STUDY DESIGN SIZE, DURATION: This prospective, assessor-blinded, multicentre, follow-up study evaluated development and health of 9-year-old IVF children born to women who were randomly assigned to IVF with PGS (PGS group) or without PGS (control group). The follow-up examination at 9 years took place between March 2014 and May 2016.PARTICIPANTS/MATERIALS, SETTING, METHODS: In total, 408 women were included and randomly assigned to IVF with or without Day-3 cleavage-stage PGS. This resulted in 52 ongoing pregnancies in the PGS group and 74 in the control group. In the PGS group, 59 children were born alive; in the control group, 85 children were born alive. At the age of 9 years, 43 children born after PGS and 56 control children participated in the study. Our primary outcome was the neurological optimality score, a sensitive measure of neurological condition assessed with a standardized, age-specific test (Touwen test). Secondary outcomes were adverse neurological condition (neurologically abnormal and the complex form of minor neurological dysfunction), cognitive development (intelligence quotient and specific domains), behaviour (parental and teacher's questionnaires), blood pressure and anthropometrics.MAIN RESULTS AND THE ROLE OF CHANCE: Neurodevelopmental outcome of PGS children did not differ from that of controls; the neurological optimality scores (mean values [(95% CI]: PGS children 51.5 [49.3; 53.7], control children 53.1 [50.5; 55.7]) were not significantly different. The prevalences of adverse neurological outcome (in all but one child implying the presence of the complex form of minor neurological dysfunction) did not differ between the groups (PGS group 17/43 [40%], control group 19/56 [34%]), although the prevalence of complex minor neurological dysfunction in both groups was rather high. Also intelligence quotient scores of the two groups were not significantly different (PGS group 114 [108; 120]); control group 117 [109; 125]), and the behaviour, blood pressure and anthropometrics of both groups did not differ. Mean blood pressures of both groups were above the 60th percentile.LIMITATIONS REASONS FOR CAUTION: The power analysis of the study was not based on the number of children needed for the follow-up study, but on the number of women who were needed to detect an increase in ongoing pregnancy rates after PGS. In addition, our study evaluated embryo biopsy in the form of PGS at cleavage stage (Day-3 embryo biopsy), while currently PGS at blastocyst stage (Day-5 embryo biopsy) is recommended and increasingly being used.WIDER IMPLICATIONS OF THE FINDINGS: Our findings indicate that PGS in cleavage stage embryos is not associated with adverse effects on neurological, cognitive and behavioural development, blood pressure and anthropometrics of offspring at 9 years. This is a reassuring finding as embryo biopsy in the forms of PGS and PGD is increasingly applied. However, both groups of IVF offspring showed high prevalences of the clinically relevant form of minor neurological dysfunction, which is a point of concern for the IVF community. In addition, our study confirms findings of others that IVF offspring may be at risk of an unfavourable cardiovascular outcome. These findings are alarming and highlight the importance of research on the underlying mechanisms of unfavourable neurodevelopmental and cardiovascular outcomes in IVF offspring.STUDY FUNDING/COMPETING INTEREST(S): The randomized controlled trial was financially supported by the Organization for Health Research and Development (ZonMw), The Netherlands (Grant number 945-03-013). The follow-up was financially supported by the University Medical Center Groningen (Grant number: 754510), the Cornelia Foundation, and the graduate schools BCN and Share, Groningen, The Netherlands. The sponsors of the study had no role in study design, data collection, data analysis, data interpretation or writing of the report. There are no conflicts of interest.TRIAL REGISTRATION NUMBER: ISRCTN76355836.

BACKGROUND: Early identification of infants at risk of cerebral palsy (CP) is desirable in order to provide early intervention. We previously demonstrated differences in knee jerk responses between 3-month-old high risk and typically developing infants.AIMS: To improve early identification by investigating whether the presence of tonic responses (continuous muscle activity occurring after the typical phasic response), clonus or contralateral responses to the knee jerk during infancy is associated with CP.STUDY DESIGN: Longitudinal EMG-study.SUBJECTS: We included 34 high-risk infants (median gestational age 31.9 weeks) who participated in the LEARN2MOVE 0-2 years trial.OUTCOME MEASURES: Video-recorded knee jerk EMG-assessments were performed during infancy (1-4 times). Developmental outcome was assessed at 21 months corrected age (CA). Binomial generalized estimating equations models with repeated measurements were fitted using predictor variables.RESULTS: Infants who later were diagnosed with CP (n = 18) showed more often than infants who were not diagnosed with CP i) tonic responses - from 4 months CA onwards, ii) clonus - from 13 months CA onwards, and iii) contralateral responses - from 15 months CA onwards.LIMITATIONS: The main limitation is the relatively small sample size.CONCLUSIONS: The assessment of tonic responses to the knee jerk using EMG may be a valuable add-on tool to appraise a high risk of CP.

Background: In typical development, postural adjustments during reaching change in the second half of infancy, including increasing rates of direction-specific adjustments. These changes are absent or different in infants at risk of cerebral palsy (CP). To discover whether these changes are related to acquisition of independent walking, we studied postural adjustments during reaching in infants before and after they learned to walk.Methods: Ten typically developing (TD) infants and 11 infants at very high risk (VHR) of CP were assessed before and after they learned to walk. Reaching movements were elicited during supported sitting, while surface electromyography was recorded of arm, neck, and trunk muscles. Percentages of direction-specific adjustments (first level of control), and recruitment patterns and anticipatory activation (second level of control) were calculated.Results: In both groups, postural adjustments during reaching were similar before and after acquisition of independent walking. Direction-specificity increased with age in typically developing infants but not in VHR-infants.Conclusion: Increasing age rather than the transition to independent walking is associated with increasing direction-specificity of TD-infants during reaching while sitting, while infants at very high risk of CP show no increase in direction-specificity, suggesting that they gradually grow into a postural deficit.

Background: The effect of forward-tilting of the seat surface and foot-support in children with spastic cerebral palsy (CP) is debated.Aim: To assess the effect of forward-tilting of the seat surface and foot-support in children with CP on kinematic head stability and reaching.Methods: Nineteen children functioning at Gross Motor Function Classification System levels I-III participated [range 6-12y; ten unilateral spastic CP (US-CP) and nine bilateral spastic CP (BS-CP)]. Kinematic data were recorded of head sway and reaching with the dominant arm in four sitting conditions: a horizontal and a 15 forward (FW) tilted seat surface, each with and without foot-support.Results: Seating condition did not affect head stability during reaching, but did affect kinematic reaching quality. The major reaching parameters, i.e., the proportion of reaches with one movement unit (MU) and the size of the transport MU, were not affected by foot-support. Forward-tilting had a positive effect on these parameters in children with US-CP, whereas the horizontal condition had this effect in children with BS-CP.Implications: A 15 degrees forward-tilted seating and foot-support do not affect head stability. Reaching in children with US-CP profits from forward-tilting; in children with BS-CP forward-tilting worsens reaching - effects that are independent of foot-support.

Purpose: Pediatric physical therapy (PPT) is characterized by heterogeneity. This blurs the evaluation of effective components of PPT. The Groningen Observation Protocol (GOP) was developed to quantify contents of PPT. This study assesses the reliability and completeness of the GOP.Methods: Sixty infant PPT sessions were video-taped. Two random samples of 10 videos were used to determine interrater and intrarater reliability using interclass correlation coefficients (ICCs) with 95% confidence intervals. Completeness of GOP 2.0 was based on 60 videos.Results: Interrater reliability of quantifying PPT actions was excellent (ICC, 0.75-1.0) in 71% and sufficient to good (ICC, 0.4-0.74) in 24% of PPT actions. Intrarater reliability was excellent in 94% and sufficient to good in 6% of PPT actions. Completeness was good for greater than 90% of PPT actions.Conclusions: GOP 2.0 has good reliability and completeness. After appropriate training, it is a useful tool to quantify PPT for children with developmental disorders.

This prospective cohort study evaluated whether the cognitive development, neurological condition, anthropometrics and blood pressure of 4-year-old IVF twins differed from those of 4-year-old IVF singletons; 103 IVF singletons and 48 IVF twins born after conventional IVF treatment were included. Primary outcome was total intelligence quotient (IQ). Secondary outcomes were minor neurological dysfunction, anthropometrics and blood pressure. Unadjusted analyses found that the total IQ score of twins was lower than that of singletons, with a mean difference of -5.4 (-9.7 to -1.0). Weight (singletons: 18.6 [18.1 to 19.1] kg; twins: 16.9 [16.0 to 17.9] kg) and height (singletons: 108.8 [107.9 to 109.8] cm; twins: 105.9 [104.0 to 107.7] cm) of twins were lower than those of singletons (mean values [95% CI]). All differences disappeared after adjusting for mediators and confounders. Neurological outcome, systolic and diastolic blood pressure of twins and singletons were similar. Four-year-old IVF twins had a lower total IQ (-5.4 points], lower bodyweight (-1.7 kg) and were shorter (-2.9 cm) than 4-year-old IVF singletons. After adjustment, the adverse twin effect disappeared, implying that increased risk for impaired health and development in twins also holds true for IVF twins, and is not altered by IVF.

STUDY QUESTION: Are the in vitro procedure, ovarian hyperstimulation or a combination of these two associated with blood pressure (BP) of 9-year-old IVF children born to subfertile couples?SUMMARY ANSWER: Our study demonstrates that ovarian hyperstimulation and the in vitro procedure are not associated with BP values in 9-year-old children born to subfertile couples.WHAT IS KNOWN ALREADY: Possible long-term effects of IVF on child health and development have been studied relatively little. This is surprising, as it is known that environmental conditions may influence embryonic and foetal development which may result in health related problems in later life. Some studies suggested that IVF is associated with higher BP at pre-school age. Yet, it is unclear whether this may be also true for older children and if so, which component of IVF, i.e. the ovarian hyperstimulation, the embryo culture or a combination of these, attributes to this potentially less favourable BP.STUDY DESIGN, SIZE, DURATION: The Groningen Assisted Reproductive Technology cohort-study is a prospective assessor-blinded study of children followed from before birth onwards. In total, 170 children were assessed at the age of 9 years. The attrition rate up until the 9-year-old assessment was 21%.PARTICIPANTS/MATERIALS, SETTING, METHODS: We evaluated cardiovascular health, focusing on BP (in mmHg and the internationally recognized percentiles of the US National High BP Education Program), heart rate and anthropometrics of 57 children born following controlled ovarian hyperstimulation-IVF/ICSI (COH-IVF/ICSI); 47 children born after modified natural cycle-IVF/ICSI (MNC-IVF/ICSI); and 66 children who were conceived naturally by subfertile couples (Sub-NC). Cardiovascular parameters were measured multiple times on one day. In addition, anthropometric data, including BMI and skinfold thickness, were collected. MAIN RESULTS AND THE ROLE OF CHANCE: Systolic BP in mmHg did not differ between the COH-IVF/ICSI (mean 106.9, SD 6.7), MNC-IVF/ICSI (mean 104.8, SD 5.9) and Sub-NC (mean 106.3, SD 5.3) groups. In addition, systolic BP percentiles did not differ between the groups: COH-IVF/ICSI (mean 62.4, SD 20.2); MNC-IVF/ICSI (mean 56.3, SD 19.3); and Sub-NC (mean 62.3, SD17.8). Also, after adjustment for confounders BP in the three groups was similar. Heart rate and anthropometric values in the three groups did not differ. For instance, BMI values in the COH-IVF/ICSI-children were 16.3 (median value, range 13.0-24.7), in MNC-IVF/ ICSI-children 16.1 (range 12.7-22.5) and in Sub-NC children 16.3 (range 12.7-24.0).LIMITATIONS, REASONS FOR CAUTION: The size of our study groups does not allow for pertinent conclusions on the effect of ovarian hyperstimulation and the in vitro procedure. The lack of a fertile control group may be regarded as another limitation.WIDER IMPLICATIONS OF THE FINDINGS: Our study suggests that ovarian hyperstimulation and in vitro procedures are not associated with cardiovascular health in 9-year-old. Yet, BP percentiles of the three groups were higher than the expected 50th percentile. This might indicate that children of subfertile couples have a higher BP than naturally conceived children.STUDY FUNDING/COMPETING INTEREST(S): The study was financially supported by the University Medical Center Groningen (UMCG), the two graduate schools of the UMCG, BCN, SHARE and the Cornelia Stichting. The sponsors of the study had no role in study design, data collection, data analysis, data interpretation or writing of the report. The authors have no conflicts of interest to declare.

Aim To assess the reliability and predictive validity of the developmental and socio‐emotional scales of the Standardized Infant NeuroDevelopmental Assessment (SINDA). Method To assess reliability, two sets of three assessors forming eight assessor‐pairs independently rated the developmental and socio‐emotional scales of 60 infants. To evaluate predictive validity, 223 infants (gestational age 30wks [range 23–41wks]; 117 males, 106 females) attending a non‐academic outpatient clinic were assessed by different assessors with SINDA’s neurological, developmental, and socio‐emotional scales. Atypical neurodevelopmental outcome at a corrected age of 24 months or older implied a Bayley Mental or Psychomotor Developmental Index score of less than 70 or neurological disorder (including cerebral palsy). Behavioural and emotional disorders were classified according to the International Classification of Diseases, 10th Revision. Predictive values were calculated from SINDA (2–12mo corrected age, median 7mo) and typical versus atypical outcome, and for intellectual disability only (Mental Developmental Index, What this paper adds Standardized Infant NeuroDevelopmental Assessment (SINDA)’s developmental and socio‐emotional scales have excellent interrater reliability.Replication of the satisfactory validity of SINDA’s neurological scale for atypical outcome.

OBJECTIVE: To evaluate the effect of 15° forward (FW) seat inclination and foot-support in children with cerebral palsy (CP) on postural adjustments during reaching.DESIGN: Observational study repeated-measures design; step two of two-step-project.SETTING: Laboratory unit within University Hospital and two special education schools.PARTICIPANTS: 19 children (ten unilateral spastic CP (US-CP); nine bilateral spastic CP (BS-CP); Gross Motor Function Classification System levels I-III; 6-12 years old). Participants were able to take part for one one-hour session.INTERVENTION: Reaching while sitting in four seating conditions (FW or horizontal seat; with or without foot-support) applied in randomized order.OUTCOME MEASURES: Simultaneously, surface electromyography (EMG) of neck, trunk and arm muscles and kinematics of head and reaching arm (step one of two-step-project) were recorded. Primary outcome parameters were the ability to modulate EMG-amplitudes at baseline and during reaching (phasic muscle activity). Other EMG-parameters were direction-specificity (1st control level), and 2nd level of control parameters: recruitment order, and anticipatory postural activity. Motor behaviour measures: ability to modulate EMG-amplitudes to kinematic characteristics of reaching and head stability.RESULTS: Only foot-support was associated with increased tonic background EMG-amplitudes and decreased phasic EMG-amplitudes of the trunk extensors in children with US-CP and BS-CP (mixed-models analyses; p-values CONCLUSION: In terms of postural adjustments during forward reaching, foot-support enhanced the children's capacity to modulate trunk extensor activity, which was associated with improved reaching quality. FW-tilting did not affect postural muscle activity.

In vitro fertilization (IVF) is not associated with neurological abnormalities in offspring's early childhood. Yet, it is unclear whether this is also true for school age. Neither do we know the role of parental subfertility in offspring's neurological development. The present study examined neurological condition at 9 years of 57 singletons born after controlled ovarian hyperstimulation IVF (COH-IVF), 46 singletons born after modified natural cycle IVF (MNC-IVF) and 66 singletons born to subfertile parents after natural conception (Sub-NC). To assess the effect of subfertility, the groups were pooled to form a subfertile group, and compared with a prospectively followed fertile reference group (n = 282). The sensitive Minor Neurological Dysfunction (MND) examination was used, resulting in the detailed Neurological Optimality Score (NOS) and the prevalence of the clinically relevant complex MND. Neurological condition of the three subfertile groups did not differ significantly: median NOS was 53 in each subfertile group and the prevalence of complex MND in the three subfertile groups was 30%, 37% and 36%, respectively. However, the NOS was lower and the prevalence of complex MND higher in children born to subfertile couples than in children of fertile couples (adjusted mean difference [95% CI]: -4.48 [-5.53 to -3.42]) and adjusted OR [95% CI]: 5.13 [2.60-10.16], respectively). We conclude that ovarian hyperstimulation, in vitro procedures, and the combination of both were not associated with a less favourable neurological outcome of 9-year-old singletons. However, the presence of parental subfertility was associated with less favourable neurological outcome of offspring at 9 years follow up.

Research on cognitive and behavioural development of children born after assisted conception is inconsistent. This prospective study aimed to explore underlying causal relationships between ovarian stimulation, in-vitro procedures, subfertility components and child cognition and behaviour. Participants were singletons born to subfertile couples after ovarian stimulation IVF (n = 63), modified natural cycle IVF (n = 53), natural conception (n = 79) and singletons born to fertile couples (reference group) (n = 98). At 4 years, cognition (Kaufmann-ABC-II; total IQ) and behaviour (Child Behavior Checklist; total problem T-score) were assessed. Causal inference search algorithms and structural equation modelling was applied to unravel causal mechanisms. Most children had typical cognitive and behavioural scores. No underlying causal effect was found between ovarian stimulation and the in-vitro procedure and outcome. Direct negative causal effects were found between severity of subfertility (time to pregnancy) and cognition and presence of subfertility and behaviour. Maternal age and maternal education acted as confounders. The study concludes that no causal effects were found between ovarian stimulation or in-vitro procedures and cognition and behaviour in children aged 4 years born to subfertile couples. Subfertility, especially severe subfertility, however, was associated with worse cognition and behaviour. (C) 2016 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

AIM: To evaluate in term infants associations between quality of general movements and developmental outcome in term infants at 6 years with either cerebral palsy (CP) or limited mobility without CP.METHOD: Participants of this prospective study were 145 term infants (86 male, 59 female). Their general movements quality was assessed at 'writhing' and 'fidgety' general movements age (3wks and 13wks post term). The assessment at 6 years consisted of a neurological examination, including assessment of minor neurological dysfunction (MND), evaluation of mobility with the Movement Assessment Battery for Children, and of behaviour and learning problems with questionnaires.RESULTS: Definitely abnormal general movements at writhing age were not associated with CP, whereas definitely abnormal general movements at fidgety age were (sensitivity 60%; specificity 91%; positive predictive value 19%, negative predictive value 98%). In children without CP, general movements quality was not associated with limited mobility, but it was associated to a minor extent with MND.INTERPRETATION: In term infants, definitely abnormal general movements at fidgety age do predict CP, but with lower accuracy than in preterm infants. General movements quality does not predict limited mobility in children without CP. The study supports suggestions that predictive value of general movements assessment in term infants is lower than that in preterm infants.

Background A difficult birth at term (DBAT) may manifest as fetal acidosis and low Apgar scores and is often referred to as “perinatal asphyxia,” especially when infants show signs of neonatal encephalopathy (NE). In contrast to DBAT resulting in moderate-to-severe NE, which is associated with neurodevelopmental disorders, little is known about the prognosis of less severe forms of DBAT, with or without NE. Objective The purpose of this study was to evaluate the International Classification of Functioning, Disability and Health, Children & Youth Version activity “mobility” and other neurodevelopmental sequelae in infants with DBAT at age 6 years. Methods The index cohort (n=62; 35 boys, 27 girls) consisted of consecutive term infants with DBAT based on clinical criteria in a Dutch nonacademic hospital from 1999 to 2005. Neonatal encephalopathy was assessed according to the Sarnat grading system and excluded infants with severe NE. The matched reference cohort (n=81; 49 boys, 32 girls) consisted of healthy term infants. The primary outcome at 6 years was limited mobility (Movement Assessment Battery for Children score ≤15th percentile). Secondary outcomes included learning and behavioral problems and the presence of minor neurological dysfunction. Results Three children developed cerebral palsy and were excluded from analyses. Children with DBAT more often had limited mobility than children without DBAT (risk ratio [RR]=2.44; 95% confidence interval [95% CI]=1.16, 5.14). The risk of limited mobility rose with increasing severity of NE (mild NE: RR=3.38; 95% CI=1.40, 8.16; moderate NE: RR=4.00; 95% CI=1.54, 10.40), and manual abilities especially were affected (RR=4.12; 95% CI=1.40, 12.14). Learning problems, need for physical therapy, and complex minor neurological dysfunction were more common in children with DBAT than in children without DBAT. Conclusions Term infants who develop mild or moderate NE following DBAT are at increased risk for limited mobility at age 6 years. Routine monitoring of neuromotor development in these children is warranted.

Background: Paediatric physiotherapy (PPT) in high-risk infants comprises family involvement, but it is unclear whether parents mediate the intervention effect. We demonstrated in a randomized controlled trial in high-risk infants comparing the family centred programme Coping and Caring for infants with special needs (COPCA) and Traditional Infant Physiotherapy (TIP) that process evaluation revealed associations between COPCA-characteristics and outcome.Aims: To assess whether PPT affects how parents position their infant during bathing and whether this is associated with child outcome.Methods and procedures: 21 infants received COPCA and 25 TIP between 3 and 6 months corrected age. Bathing sessions were videotaped at 3, 6 and 18 months. Time spent with specific infant positions was correlated with quantified PPT-actions and functional mobility at 18 months measured with the Paediatric Evaluation of Disability Inventory (PEDI).Outcomes and results: At 3 and 18 months bathing position was similar in both groups, but differed at 6 months (time spent on sitting: COPCA 77.7%, TIP 39.2%; median difference 32.0% (95% CI: 10.6-50.5%). Sitting-time at 6 months was associated with higher PEDI functional mobility scores.Conclusions and implications: Early PPT may affect parental behaviour, such as infant positioning during bathing, which, in turn, may affect child development.

Item does not contain fulltext BACKGROUND: Following our clinical observation of tonic responses in response to the knee jerk in infants at very high risk for cerebral palsy (VHR infants), we systematically studied tonic responses, clonus, and reflex irradiation. We questioned (i) whether these responses occurred more often in VHR infants than in typically developing (TD) infants, and (ii) whether they were associated with abnormal general movement quality. METHODS: Twenty-four VHR and 26 TD infants were assessed around 3 mo corrected age. Surface electromyograms of leg, trunk, neck, and arm muscles were recorded while eliciting the knee jerk. All assessments were video-recorded. RESULTS: VHR infants more often than TD infants showed tonic responses in the ipsilateral quadriceps and hamstring (Mann-Whitney U; P = 0.0005 and P = 0.0009), clonus (Chi-square; P = 0.0005) and phasic responses in the contralateral quadriceps and hamstring (Mann-Whitney U; P = 0.002 and P = 0.0003, respectively). Widespread reflex irradiation occurred in VHR and TD infants. Definitely abnormal general movements and stiff movements were associated with tonic responses (Mann-Whitney U; P = 0.0005, P = 0.007, respectively) and clonus (Mann-Whitney U; P = 0.003 and P = 0.0005) in the ipsilateral quadriceps. CONCLUSION: Similar to clonus, tonic responses may be regarded as a marker of a loss of supraspinal control. Reflex irradiation primarily is a neurodevelopmental phenomenon of early ontogeny.

Background: Movement complexity and the presence of fidgety movements (FMs) during general movements (GMs) both reflect aspects of neurological integrity in early infancy.Aim: To assess interrelations between the degree of movement complexity and characteristics of FMs during typical GMs and to investigate associations between mildly impaired GMs and risk factors and neurodevelopmental condition.Study design: Observational cohort study.Subjects: 283 infants (25 born preterm) at 2-4 months corrected age, representative of the general Dutch population.Outcome measures: GMs were classified in terms of GM-complexity (normal or mildly abnormal (MA)) and FMs (clearly present, sporadic, or exaggerated). Concurrent neurological, developmental and socio-emotional status were measured with the Standardized Infant NeuroDevelopmental Assessment (SINDA).Results: Infants with MA GM-complexity had a higher risk of having sporadic FMs and exaggerated FMs. Perinatal complications were not associated with mildly impaired GMs. MA GM-complexity was associated with advanced maternal age (adjusted OR = 2.29 [1.11, 4.76]) and having a non-native Dutch mother (adjusted OR = 2.93 [1.29, 6.64]). It was also associated with atypical neurological (OR = 7.62 [3.51, 16.54]) and developmental scores (OR = 2.38 [1.16, 4.88]). Sporadic and exaggerated FMs were associated with low-to-middle maternal education (adjusted OR = 2.88, [1.45, 5.72]) and having a non-native Dutch father (adjusted OR = 7.16 [1.41, 36.32]), respectively. However, neither sporadic nor exaggerated FMs were associated with the SINDA outcomes.Conclusions: GM-complexity and FMs are two interrelated but different aspects of GMs. Mild impairments in GM-complexity and FMs share a non-optimal socio-economic background as risk factor, but only MA GM-complexity is associated with a concurrent non-optimal neurodevelopmental condition.

AIMS: The aim of our observational longitudinal study is to evaluate changes over time in standard pediatric physical therapy (PPT) for infants at risk of neurodevelopmental disorders.METHODS: Treatment sessions in two time periods (2003-2005 [n = 22] and 2008-2014 [n = 16]) were video recorded and analyzed quantitatively in five categories: neuromotor actions, educational actions, communication, position, and situation of treatment session. Differences in percentages of time spent on therapeutic actions between periods were tested with Mann-Whitney U and Hodges Lehmann's tests.RESULTS: No significant changes appeared in the main categories of neuromotor actions. Time spent on not-specified educational actions toward caregivers (median from 99% to 81%, p = .042) and not-specified communication (median from 72% to 52%, p = .002) decreased. Consequently, time spent on specific educational actions (caregiver training and coaching; median from 1% to 19%, p = .042) and specific communication (information exchange, instruct, provide feedback; median from 21% to 38%, p = .007) increased. Infant position changed only minimally: time spent on transitions-that is, change of position-decreased slightly over time (median from 7% to 6%, p = .042). Situation of treatment session did not change significantly over time.CONCLUSIONS: Neuromotor actions in PPT remained largely stable over time. Specific educational actions and communication increased, indicating larger family involvement during treatment sessions.

Background: Development of postural problems in Cerebral Palsy (CP) is largely unknown. Postural muscle activity is organized into two levels: 1) direction-specificity; 2) fine-tuning of direction-specific activity.Aim: To study development of postural control until 21 months corrected age in subgroups of infants at very high-risk (VHR) of CP: a) with and without CP at 21 months; b) with and without cystic periventricular leukomalacia (cPVL), the brain lesion with highest risk of CP.Methods and procedures: Longitudinal electromyography recordings of postural muscles during reaching were made in 38 VHR-infants (severe brain lesion or clear neurological signs) between 4.7 and 22.6 months (18 CP, of which 8 with cPVL). Developmental trajectories were calculated using linear mixed effect models.Outcomes and results: VHR-infants with and without CP showed virtually similar postural development throughout infancy. The subgroup of VHR-infants with cPVL improved performance in direction-specificity with increasing age, while they performed throughout infancy worse in fine-tuning of postural adjustments than infants without cPVL.Conclusions and implications: VHR-infants with and without CP have a similar postural development that differs from published trajectories of typically developing infants. Infants with cPVL present from early age onwards dysfunctions in fine-tuning of postural adjustments; they focus on direction-specificity.

Aim: Evidence is accumulating that motor and cognitive development are interrelated. This study investigates associations between motor development in infancy and cognitive function at 4 years of age. Method: This study is part of the Groningen prospective cohort study on the development of children born after assisted reproductive techniques such as in vitro fertilization. The study group consisted of 223 children (119 males, 104 females) born to subfertile couples (median gestational age 39.6wks, range 30-43wks). Motor behaviour was assessed with the Infant Motor Profile (IMP) at 4 months, 10 months, and 18 months. IQ was evaluated at 4 years with the Kaufman Assessment Battery for Children, Second Edition. Latent class growth modelling was used to analyse relations between IMP and IQ scores. Results: Infants with low total IMP scores had an IQ that was 8.9 points lower at 4 years than infants with typical IMP scores (95% confidence interval 3.6-14.1). Also, low scores in the domains of variation and performance were associated with a lower IQ at 4 years of age, by 6.1 points and 13.2 points respectively. Interpretation: Motor development in relatively low-risk infants is associated with cognition at 4 years of age. In particular, low motor variation and performance are associated with a lower IQ at 4 years of age. What this paper adds: Motor development in infancy is directly related to cognitive function at 4 years of age. This relationship is most pronounced for infant motor variation and performance. The size of the differences in IQ is clinically relevant.

Increased childhood blood pressure (BP) can lead to increased BP later in life and even small increases have been associated with a higher risk of adult cardiovascular disease. In contrast, lower childhood BP has been associated with more favourable health outcomes. One study found that a 2 mmHg reduction in childhood diastolic BP was associated with a 17% decrease in the prevalence of adult hypertension . This article is protected by copyright.

This study evaluated the prevalence of asthma and asthma medication use in 213 4-year-old singletons followed from birth onwards, including three groups of children born following: (i) controlled ovarian hyperstimulation IVF/intracytoplasmic sperm injection (ICSI); (ii) modified natural cycle IVF/ICSI; and (iii) natural conception in subfertile couples. The rate of asthma medication was higher in the ovarian hyperstimulation-IVF/ICSI than in the subfertile group (adjusted odds ratios [aOR]: 1.96 [1.00-3.84]). Time to pregnancy, a proxy for the severity of subfertility, was not associated with asthma and asthma medication. In conclusion, controlled ovarian hyperstimulation- IVF/ICSI is associated with the use of asthma medication in 4-year-old offspring of subfertile couples. (C) 2015 Reproductive Healthcare Ltd.

Background: Long-chain polyunsaturated fatty acids (LCPUFA) are important for prenatal brain development. Previous studies of others assessed outcome until 7 years. The associations between neonatal LCPUFA status and long-term developmental outcome are debated.Aim: To investigate the relationship between fatty acid status at birth and neurodevelopment at 9 years. Age 9 is a unique age after a significant neurodevelopmental transition.Study design: Correlation study. Multivariable analyses were carried out to adjust for potential confounders.Subjects: 317 children who participated in a trial on effects of postnatal LCPUFA supplementation were eligible. 235 children (74%) were reassessed at age 9.Outcome measures: At birth, docosahexaenoic acid (DHA) and arachidonic acid (AA) were determined in the wall of the umbilical vein. We primarily studied the correlation between DHA and AA with the complex form of minor neurological dysfunction (cMND). Secondary correlations that were studied were DMA and AA levels with cognitive development in terms of full IQ and with behavioural development in terms of a total problem score.Results: Boys with cMND showed lower DMA values in the umbilical vein than children with better neurological condition (p = 0.033). A similar association was absent in girls. Neonatal AA values were not associated with neurological outcome. Neither neonatal DHA nor AA values were associated with cognition and behaviour at 9.Conclusions: Higher umbilical DHA levels in boys are associated with better neurological development at 9 years. AA status at birth was not associated with neurodevelopment at 9 years. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

Item does not contain fulltext AIM: To assess development of reaching and head stability in infants at very high risk (VHR-infants) of cerebral palsy (CP) who did and did not develop CP. METHOD: This explorative longitudinal study assessed the kinematics of reaching and head sway in sitting in 37 VHR-infants (18 CP) one to four times between 4.7 months and 22.6 months corrected age. Developmental trajectories were calculated using linear mixed effect models. Motor function was evaluated with the Infant Motor Profile (IMP) around 13 months corrected age. RESULTS: Throughout infancy, VHR-infants with CP had a worse reaching quality than infants without CP, reflected for example by more movement units (factor 1.52, 95% CI 1.16-1.99) and smaller transport movement units (factor 1.86, 95% CI 1.20-2.90). Total head sway of infants with and without CP was similar, but infants with CP used more head movement units to achieve stability. The rate of developmental change in infants with and without CP was similar. Around 13 months, head control and reaching quality were interrelated; both were associated with IMP-scores. INTERPRETATION: Infants with CP showed a worse kinematic reaching quality and head stability throughout infancy from early age onwards than VHR-infants without CP, implying that kinematically they do not grow into a deficit, but exhibit deficits from early infancy on. WHAT THIS PAPER ADDS: Reaching quality improves throughout infancy in all infants at high risk (VHR-infants). Infants with cerebral palsy (CP) show a worse reaching quality than VHR-infants without CP. Infants with CP achieve head stability differently from infants without CP. Infants with CP exhibit kinematic reaching problems from early age onwards.

AimThe aim of this study was to assess the associations between dysmorphic features and neurological, mental, psychomotor, and behavioural development in order to improve our understanding of aetiological pathways leading to minor developmental problems.MethodIn our cross-sectional study, 272 generally healthy 2-year-olds (143 males, 129 females; median gestational age 39weeks, [range 30-43wks]), born after a parental history of subfertility either with or without fertility treatment, were examined. Dysmorphic features were classified as abnormalities (clinically relevant or not), minor anomalies, or common variants according to Merks' classification system. Hempel's neurological assessment resulted in a neurological optimality score (NOS) and fluency score. Mental and psychomotor development were assessed with the Dutch version of the Bayley Scales of Infant Development and behavioural development with the Achenbach Child Behaviour Checklist.ResultsOf the different types of dysmorphic feature, clinically relevant abnormalities were most strongly associated with a lower NOS (difference -2.53, 95% confidence interval [CI] -4.23 to -0.83) and fluency score (difference -0.62, 95% CI -1.1 to -0.15). The presence of one or more abnormalities (clinically relevant or not) or one or more common variants was significantly associated with a lower NOS, and the presence of three or more minor anomalies was associated with lower fluency scores. Dysmorphic features were not associated with mental, psychomotor, or behavioural development.InterpretationAs dysmorphic features originate during the first trimester of pregnancy, the association between dysmorphic features and minor alterations in neurodevelopment may suggest an early ontogenetic origin of subtle neurological deviations.What this paper addsWe found that dysmorphic features are associated with minor alterations in neurological development.This finding suggests an early ontogenetic origin of subtle neurological deviations.

Aim To evaluate a kinematic paradigm of automatic general movements analysis in comparison to clinical assessment in 3-month-old infants and its prediction for neurodevelopmental outcome. Method Preterm infants at high risk (n=49; 26 males, 23 females) and term infants at low risk (n=18; eight males, 10 females) of developmental impairment were recruited from hospitals around Heidelberg, Germany. Kinematic analysis of general movements by magnet tracking and clinical video-based assessment of general movements were performed at 3 months of age. Neurodevelopmental outcome was evaluated at 2 years. By comparing the general movements of small samples of children with and without cerebral palsy (CP), we developed a kinematic paradigm typical for infants at risk of developing CP. We tested the validity of this paradigm as a tool to predict CP and neurodevelopmental impairment. Results Clinical assessment correctly identified almost all infants with neurodevelopmental impairment including CP, but did not predict if the infant would be affected by CP or not. The kinematic analysis, in particular the stereotypy score of arm movements, was an excellent predictor of CP, whereas stereotyped repetitive movements of the legs predicted any neurodevelopmental impairment. Interpretation The automatic assessment of the stereotypy score by magnet tracking in 3-month-old spontaneously moving infants at high risk of developmental abnormalities allowed a valid detection of infants affected and unaffected by CP.

Objective: To study whether specific congenital anomalies occur more often with a history of subfertility and/or the use of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI).Design: Case-only analyses.Setting: Not applicable.Patient(s): We included live births, stillbirths, and terminated pregnancies with congenital anomalies without a known cause that had a birth year between 1997 and 2010 (n = 4,525). A total of 4,185 malformed cases were born to fertile couples and 340 to subfertile couples, of whom 139 had conceived after IVF/ICSI and 201 had conceived naturally after >12 months.Intervention(s): None.Main Outcome Measure(s): The contribution, expressed in odds ratios (ORs), of a history of subfertility and IVF/ICSI to each specific type of congenital anomaly, imprinting disorder, and syndromal disorder.Result(s): We found subfertility to be associated with an increase in abdominal wall defects (adjusted OR [aOR] 2.43, 95% CI 1.05-5.62), penoscrotal hypospadia (aOR 9.83, 95% CI 3.58-27.04), right ventricular outflow tract obstruction (aOR 1.77, 95% CI 1.06-2.97), and methylation defects causing imprinting disorders (aOR 13.49, 95% CI 2.93-62.06). In vitro fertilization/ICSI was associated with an increased risk of polydactyly (OR 4.83, 95% CI 1.39-16.77) and more specifically polydactyly of the hands (OR 5.02, 95% CI 1.43-17.65).Conclusion(s): In our registry-based study, parental subfertility was associated with an increase in abdominal wall defects, penoscrotal hypospadia, right ventricular outflow tract obstruction, and methylation defects causing imprinting disorders. In vitro fertilization/ICSI was associated with an increase in polydactyly, mainly of the hands. (C) 2015 by American Society for Reproductive Medicine.

The aim of this work was to investigate in a prospective study whether moderate hyperbilirubinemia in healthy term neonates is associated with an increase of minor neurological dysfunction (MND) and behavioral problems up to 18 mo. We enrolled 43 healthy term infants with a bilirubin level ≥220 µmol/l (BILI group) at 72–96 h postnatally at the University Medical Center Groningen (UMCG), including eight referrals for hyperbilirubinemia. Seventy healthy term infants born at the UMCG with bilirubin level

Objective: To evaluate the effect of preimplantation genetic screening (PGS) on morphologic outcome in children.Design: Follow-up of a randomized controlled trial (RCT).Setting: University hospital.Patient(s): Two-year-old children born to mothers who participated in an RCT on the efficacy of PGS: 50 children born after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) with PGS (intervention group; PGS+) and 72 children born after IVF/ICSI only (control group; PGS-). Sixty-six age-matched children conceived without any form of assisted reproduction were recruited separately in a local public health service center (reference group).Intervention(s): PGS.Main Outcome Measure(s): Body surface examination and anthropometry. The evaluation of morphologic abnormalities allowed assessment of children's phenotype in detail. Morphologic abnormalities were classified as major abnormalities (abnormal development in organogenesis, deformations, disruptions, or dysplasia) and minor anomalies (deviations in phenogenesis).Result(s): The percentage of children with >= 1 major abnormality was 28% in the PGS+ and 35% in the PGS - group [difference - 7%, 95% CI - 23% to 10%]. The percentage of children with >= 1 minor anomaly was 64% in the PGS+ and 67% in the PGS - group [difference - 3%, 95% CI - 15% to 20%]. In the reference group 30% of the children had >= 1 major abnormality [95% CI 20% to 43%] and 74% had >= 1 minor anomaly [95% CI 62% to 84%].Conclusion(s): No statistically significant differences were found in minor anomalies between children conceived after IVF/ICSI with or without PGS. There is = 10% more major abnormalities in children born after PGS. (Fertil Steril (R) 2013;99:408-13. (C) 2013 by American Society for Reproductive Medicine.)

Aim: To investigate associations between neurological condition, assessed with the Hempel examination, in terms of minor neurological dysfunction (MND) and neurological optimality, and cognition and behaviour at 4 years.Study design: Cross-sectional analyses within a prospective, assessor-blinded follow-up study.Subjects: Four-year-old singletons born to subfertile parents (n = 235; 120 boys).Outcome measures: Outcome parameters were complex minor neurological dysfunction (complex MND) and the neurological optimality score (NOS). Cognitive outcome was evaluated with the Kaufman Assessment Battery for Children, resulting in a total intelligence quotient (IQ). Behavioural outcome was evaluated with the Child Behavior Checklist, resulting in a total problem T-score.Results: Fifty-seven (24.3%) children had complex MND. None of the children showed fine motor dysfunction, suggesting a ceiling effect of the Hempel assessment. Complex MND was not correlated with IQ or total problem T-score. Nevertheless, a higher NOS was correlated with a higher IQ and a lower total problem T-score (adjusted mean estimate [95% confidence interval]: cognition: 0.445 [0.026; 0.865], p = 0.038; behaviour: - 0.458 [- 0.830; - 0.087], p = 0.016).Interpretation: At age 4, complex MND assessed with the Hempel assessment was not associated with cognition and behaviour, presumably due to a ceiling effect in the Hempel domain of fine motor function. A more optimal neurological condition was associated with higher IQ and better behaviour.

Background: The long-term effect of early intervention in infants at risk for developmental disorders is unclear. The VIP project (n = 46, originally) evaluated by means of a randomised controlled trial the effect of the family centred early intervention programme COPCA (Coping with and Caring for infants with special needs) in comparison to that of traditional infant physiotherapy (TIP).Aims: To evaluate the effect of early intervention on functional outcome at school age.Methods and procedures: Parents of 40 children (median age 83 years) participated in this follow-up study. Outcome was assessed with a standardised parental interview (Vineland Adaptive Behaviour Scale) and questionnaires (Developmental Coordination Disorder Questionnaire, Child Behaviour Checklist, Utrechtse Coping List, and questions on educational approach). Quantified video information on physiotherapeutic actions during infancy was available.Outcomes and results: Child functional outcome in the two randomised groups was similar. Process evaluation revealed that some physiotherapeutic actions were associated with child mobility and parental educational approach at follow-up: e.g., training and instructing were associated with worse mobility.Conclusions and implications: Functional outcome at school age after early intervention with COPCA is similar to that after TIP. However, some specific physiotherapeutic actions, in particular the physiotherapist's approach, are associated with outcome.What this paper adds: Early intervention is generally applied in infants at risk for developing disorders, with the aim of improving overall functional outcome. However, little is known on the long-term effect. The VIP project evaluated by means of a randomised controlled trial the effect of the family centred early intervention programme COPCA (Coping with and Caring for infants with special needs) in comparison to that of traditional infant physical therapy (TIP). Outcome at 18 months corrected age was virtually similar. Process evaluation of the physiotherapy actions revealed that some characteristics of COPCA were associated with improved developmental outcome at 18 months. This paper presents data on functional outcome at school age (median 83 years) in 87% of the original participants. Outcome of infants who received three months of COPCA and that of infants who received three months of TIP was similar. Yet, parents of families who had received the COPCA intervention still more often used a trial and error approach when the child learned a new skill than parents of children who had received TIP. Process evaluation showed that more time spent on caregiver training and strict instructions during early intervention was associated with worse mobility. Four other physiotherapeutic actions were associated with parental educational approach. None of the neuromotor actions were associated with child outcome at school age.We conclude that long-term outcome after three months of COPCA or TIP is similar. However, our study does suggest that the professional approach of the physiotherapist can make a difference. (C) 2017 Elsevier Ireland Ltd. All rights reserved.

General movements (GM) are used in academic settings to predict developmental outcome in infants born preterm. However, little is known about the implementation and predictive value of GM in non-academic settings.The aim of this study is twofold: To document the implementation of GM assessment (GMA) in a non-academic setting and to assess its predictive value in infants born preterm.We documented the process of implementing GMA in a non-academic outpatient clinic. In addition, we assessed the predictive value of GMA at 1 and 3 months' corrected age for motor and cognitive development at 2 years in 122 children born33 weeks' gestation. Outcome at two years was based upon the Bayley Scales of Infant Development-II (mental/psychomotor developmental index (MDI, PDI)) and a neurological examination. The infants' odds of atypical outcome (MDI or PDI ≤70 or diagnosis CP) and the predictive accuracy of abnormal GMA were calculated in a clinical routine scenario, which used all available GM information (primarily at 3 months or at 1 month, when 3 months were not available). In addition, separate analysis was undertaken for the samples of GMA at 1 and 3 months.Tips to facilitate GMA implementation are described. In our clinical routine scenario, children with definitely abnormal GM were more likely to have an atypical two-year outcome than children with normal GM (OR 13.2 (95% CI 1.56; 112.5); sensitivity 55.6%, specificity 82.1%). Definitely abnormal GM were associated with reduced MDI (-12.0, 95% CI -23.2; -0.87) and identified all children with cerebral palsy (CP) in the sample of GMA at 3 months only.GMA can be successfully implemented in a non-academic outpatient setting. In our clinical routine scenario, GMA allowed for adequate prediction of neurodevelopment in infants born preterm, thereby allaying concerns about diagnostic accuracy in non-academic settings.

Background: General movement (GM) assessment is a well-established tool to predict cerebral palsy in high-risk infants. Little is known on the predictive value of GM assessment in low-risk populations.Aims: To assess the predictive value of GM quality in early infancy for the development of the clinically relevant form of minor neurological dysfunction (complex MND) and behavioral problems at preschool age.Study design: Prospective cohort study.Subjects: A total of 216 members of the prospective Groningen Assisted Reproductive Techniques (ART) cohort study were included in this study. ART did not affect neurodevelopmental outcome of these relatively low-risk infants born to subfertile parents.Outcome measures: GM quality was determined at 2 weeks and 3 months. At 18 months and 4 years, the Hempel neurological examination was used to assess MND. At 4 years, parents completed the Child Behavior Checklist; this resulted in the total problem score (TPS), internalizing problem score (IPS), and externalizing problem score (EPS). Predictive values of definitely (DA) and mildly (MA) abnormal GMs were calculated.Results: DA GMs at 2 weeks were associated with complex MND at 18 months and atypical TPS and IPS at 4 years (all p Conclusions: GM quality as a single predictor for complex MND and behavioral problems at preschool age has limited clinical value in children at low risk for developmental disorders.

Contains fulltext : 165777.pdf (Publisher’s version ) (Closed access) AIM: Having observed slow pupillary light responses (PLRs) in infants at high risk of cerebral palsy, we retrospectively evaluated whether these were associated with specific brain lesions or unfavourable outcomes. METHODS: We carried out neurological examinations on 30 infants at very high risk of cerebral palsy five times until the corrected age of 21 months, classifying each PLR assessment as normal or slow. The predominant reaction during development was determined for each infant. Neonatal brain scans were classified based on the type of brain lesion. Developmental outcome was evaluated at 21 months of corrected age with a neurological examination, the Bayley Scales of Infant Development Second Edition and the Infant Motor Profile. RESULTS: Of the 30 infants, 16 developed cerebral palsy. Predominantly slow PLRs were observed in eight infants and were associated with periventricular leukomalacia (p = 0.007), cerebral palsy (p = 0.039), bilateral cerebral palsy (p = 0.001), poorer quality of motor behaviour (p < 0.0005) and poorer cognitive outcome (p = 0.045). CONCLUSION: This explorative study suggested that predominantly slow PLR in infants at high risk of cerebral palsy were associated with periventricular leukomalacia and poorer developmental outcome. Slow PLR might be an expression of white matter damage, resulting in dysfunction of the complex cortico-subcortical circuitries.

Background: Assessing the quality of general movements (GMs) is a non-invasive tool to identify at early age infants at risk for developmental disorders.Aim: To investigate whether specific characteristics of definitely abnormal GMs are associated with developmental outcome at school age.Study design: Observational cohort study (long-term follow-up).Subjects: Parents of 40 children (median age 83 years, 20 girls) participated in this follow-up study. In infancy (median corrected age 10 weeks), the children (median gestational age 303 weeks; birth weight 1243 g) had shown definitely abnormal GMs according to Hadders-Algra (2004). Information on specific GM characteristics such as the presence of fidgety movements, degree of complexity and variation, and stiff movements, was available (see Hamer et al. 2011).Outcome measures: A standardised parental interview (presence of CP, attendance of school for special education, Vineland Adaptive Behavior Scale to determine functional performance) and questionnaires (Developmental Coordination Disorder Questionnaire [DCD-Q] to evaluate mobility and Child Behavior Checklist to assess behaviour) were used as outcome measures.Results: Six children had cerebral palsy (CP), ten children attended a school for special education, and eight children had behavioural problems. Both the absence of fidgety movements and the presence of stiff movements were associated with CP (p = 0.001; p = 0.003, respectively). Stiff movements were also related to the need of special education (p = 0.009). A lack of movement complexity and variation was associated with behavioural problems (p = 0.007). None of the GM characteristics were related to DCD-Q scores.Conclusions: The evaluation of fidgety movements and movement stiffness may increase the predictive power of definitely abnormal GMs for motor outcome in particular CP. This study endorses the notion that the quality of GMs reflects the integrity of the infant's brain, assisting prediction of long-term outcome. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
