Neuromotor development in infants with cerebral palsy investigated by the Hammersmith Infant Neurological Examination during the first year of age

Longitudinal Hammersmith Infant Neurological Examination (HINE) Trajectories in Children with Cerebral Palsy Identified in High-Risk Follow-Up

Background/Objectives: The Hammersmith Infant Neurological Examination (HINE) is a standardized neurologic exam for infants between 2 and 24 months. Scores can be compared to optimality cutoffs as one component to support an early diagnosis of cerebral palsy (CP). Some prognosis is also possible for infants diagnosed with CP. We aimed to understand the longitudinal trajectories of HINE scores in infants who were ultimately diagnosed with CP. Methods: Clinical records were reviewed for children who were diagnosed with CP in two high-risk infant follow-up clinics with HINE scores from at least two visits between the corrected ages of 3 months and 2 years. Trajectories were calculated individually and by group for infants in four categories-term neonatal hypoxic ischemic encephalopathy (HIE), term perinatal arterial ischemic stroke (PAIS), premature infants with brain injury, and "Other" (term infants with congenital malformations and/or congenital hydrocephalus). The changes in HINE scores between clinic visits were compared using linear mixed-effect models with a random intercept, pulling data by diagnostic group across visits and accounting for within-child correlations of scores over the follow-up time. Results: The changes in HINE scores for sixty children (twenty-five with prematurity, eighteen with HIE, seven with PAIS, and ten in the other category) were assessed. The linear mixed-effect models indicated that the infants with PAIS had an estimated 10.8-point increase in total HINE scores after 9 months of age compared to earlier assessments (95% CI [2.5, 19.2]. There was no statistically significant improvement in the scores among the infants in the other brain injury groups. The infants with PAIS had an estimated 2.9-point increase in HINE asymmetry scores after 9 months of age compared to prior visits (95% CI [0.7, 5.1]). None of the other diagnostic categories had statistically significant increases in asymmetry scores over time. Conclusions: The children with PAIS with resultant hemiplegia showed increasing HINE scores throughout the first two years of life. In contrast, the HINE scores remained stable for those children with term HIE, prematurity-associated brain injury, and congenital malformations and/or congenital hydrocephalus diagnosed with CP. Tracking individual changes (or stability) in HINE scores can aid diagnosis, inform prognosis, and guide the design of clinical trials targeting neurologic injury.

Data-Driven Early Prediction of Cerebral Palsy Using AutoML and interpretable kinematic features

Early identification of cerebral palsy (CP) remains a major challenge due to the reliance on expert assessments that are time-intensive and not scalable. Consequently, a range of studies have aimed at using machine learning to predict CP scores based on motion tracking,e.g. from video data. These studies generally predict clinical scores which are a proxy for CP risk. However, clinicians do not REALLY want to estimate scores, they want to estimate the patients' risk of developing clinical symptoms. Here we present a data-driven machine-learning (ML) pipeline that extracts movement features from infant video based motion tracking and estimates CP risk using AutoML. Using AutoSklearn, our framework minimizes risk of overfitting by abstracting away researcher-driver hyperparameter optimization. Trained on movement data from 3- to 4-month-old infants, our classifier predicts a highly indicative clinical score (General Movements Assessment [GMA]) with an ROC-AUC of 0.78 on a held-out test set, indicating that kinematic movement features capture clinically relevant variability. Without retraining, the same model predicts the risk of cerebral palsy outcomes at later clinical follow-ups with an ROC-AUC of 0.74, demonstrating that early motor representations generalize to long-term neurodevelopmental risk. We employ pre-registered lock-box validation to ensure rig-orous performance evaluation. This study highlights the potential of AutoML-powered movement analytics for neurodevelopmental screening, demonstrating that data-driven feature extraction from movement trajectories can provide an interpretable and scalable approach to early risk assessment. By integrating pre-trained vision transformers, AutoML-driven model selection, and rigorous validation protocols, this work advances the use of video-derived movement features for scalable, data-driven clinical assessment, demonstrating how computational methods based on readily available data like infant videos can enhance early risk detection in neurodevelopmental disorders.

Randomized Comparison Trial of Rehabilitation Very Early for Infants with Congenital Hemiplegia

OBJECTIVE

To compare efficacy of constraint-induced movement therapy (Baby-CIMT) with bimanual therapy (Baby-BIM) in infants at high risk of unilateral cerebral palsy.

STUDY DESIGN

This was a single-blind, randomized-comparison-trial that had the following inclusion criteria: (1) asymmetric brain lesion (2) absent fidgety General Movements, (3) Hammersmith Infant Neurological Examination below cerebral palsy cut-points, (4) entry at 3-9 months of corrected age, and (5) >3-point difference between hands on Hand Assessment Infants (HAI). Infants were randomized to Baby-CIMT or Baby-BIM, which comprised 6-9 months of home-based intervention. Daily dose varied from 20 to 40 minutes according to age (total 70-89.2 hours). Primary outcome measure was the HAI after intervention, with secondary outcomes Mini-Assisting Hand Assessment and Bayley III cognition at 24 months of corrected age.

RESULTS

In total, 96 infants (51 male, 52 right hemiplegia) born median at 37-weeks of gestation were randomized to Baby-CIMT (n = 46) or Baby-BIM (n = 50) and commenced intervention at a mean 6.5 (SD 1.6) months corrected age. There were no between group differences immediately after intervention on HAI (mean difference [MD] 0.98 HAI units, 95% CI 0.94-2.91; P = .31). Both groups demonstrated significant clinically important improvements from baseline to after intervention (Baby-BIM MD 3.48, 95% CI 2.09-4.87; Baby-CIMT MD 4.42, 95% CI 3.07-5.77). At 24 months, 64 infants were diagnosed with unilateral cerebral palsy (35 Baby-CIMT, 29 Baby-BIM). Infants who entered the study between 3 and 6 months of corrected age had greater change in HAI Both Hands Sum Score compared with those who entered at ≥6 months of corrected age (MD 7.17, 95% CI 2.93-11.41, P = .001).

CONCLUSIONS

Baby-CIMT was not superior to Baby-BIM, and both interventions improved hand development. Infants commencing intervention at <6 months corrected age had greater improvements in hand function.

Early Diagnosis of Cerebral Palsy in Preterm Infants with MRI, General Movements and Neurological Exam

Background

The increasing clinical use of combining structural MRI (sMRI) with General Movements Assessment (GMA) or Hammersmith Infant Neurological Exam (HINE) before five months corrected age (CA) for early diagnosis of cerebral palsy (CP) lacks sufficient prognostic data for children with CP, especially those with Gross Motor Function Classification System (GMFCS) I.

Objective

Evaluate the predictive value of sMRI, GMA, and HINE individually and in combination for early CP diagnosis and assess accuracy across varying GMFCS levels in a regional cohort of preterm infants.

Methods

We performed sMRI between 39-44 weeks postmenstrual age and GMA and HINE between 12-18 weeks CA in 395 preterm infants born at ≤32 weeks' gestation across five NICUs in Greater Cincinnati. Brain abnormalities on sMRI included white matter injuries, cortical and deep gray matter lesions, or extensive cerebellar hemorrhage. Absent fidgety movements constituted abnormal GMA; abnormal HINEs were scores <56. The primary outcome was CP diagnosis at 22-26 months CA, classified by the GMFCS. We calculated sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratios for individual tests and combinations.

Results

Of 338 (86%) infants with complete follow-up, 48 (14.2%) showed sMRI abnormalities, 15 (4.6%) had abnormal GMA, and 69 (20.9%) had abnormal HINE. Thirty-nine children (11.5%) developed CP at age 2, of which 28 had GMFCS level I and 11 had GMFCS >II. The combination of sMRI and GMA achieved 100% specificity but only 22% sensitivity while the combination of abnormal sMRI and HINE demonstrated sensitivity of 32% and specificity of 98% for prediction of CP. Individual or combined tests showed far higher sensitivity (78-100%) for predicting CP in children with GMFCS levels II-V.

Conclusions

The combination of sMRI with GMA or HINE demonstrated high specificity but low sensitivity for early CP diagnosis in a regional cohort of preterm infants. This approach appears effective for early detection of CP levels II-V but not for level I cases, the most prevalent type, underscoring the need for continued developmental follow-up for all very preterm infants and need for more sensitive diagnostic tools for early detection of CP.

Key Points

Questions: What is the individual and combined prognostic accuracy of sMRI, GMA, and HINE for early diagnosis of CP in preterm infants?Findings: In our prospective, regional study of preterm infants born at ≤32 weeks' gestation, we found that combining brain abnormalities on sMRI with abnormal GMA achieved 100% specificity but 22% sensitivity for diagnosing CP. Individual or combined tests showed far higher sensitivity (78-100%) for predicting CP in children with GMFCS levels II-V. Both individual and combined tests were poor predictors of GMFCS level I CP, the most common type.Meaning: While sMRI combined with GMA or HINE is effective for diagnosing CP with GMFCS levels II-V, this approach falls short for children with GMFCS level I.

Baby Observational Selective Control AppRaisal (BabyOSCAR): Scores at 3 months predict functional ability, spastic cerebral palsy distribution, and diagnosis at 2 years

AIM

To assess the predictive capabilities of the Baby Observational Selective Control AppRaisal (BabyOSCAR) tool, administered at 3 months corrected age, in determining spastic cerebral palsy (CP) outcome, functional abilities, and body topography at 2 years of age or later.

METHOD

Independent joint motions were measured at age 10 to 16 weeks from video recordings of spontaneous movement using BabyOSCAR in a sample of 75 infants. All included infants had known 2-year outcomes (45 with spastic CP and 30 without CP) including Gross Motor Functional Classification System (GMFCS) levels and CP body distribution. Receiver operating characteristic curves and cut points indicating greatest sensitivity and specificity were generated for predictive performance.

RESULTS

Total BabyOSCAR score was a strong predictor of future outcome of spastic CP (cut score of 22.5, sensitivity = 98%, specificity = 100%, area under the curve = 0.99), and was able to distinguish children classified in GMFCS levels I and II from those in III to V (cut score of 13.5, sensitivity = 92%, specificity = 89%, area under the curve = 0.94). Having an (absolute) asymmetry score on the BabyOSCAR of more than 5 was a predictor of having unilateral CP at age 2 years (sensitivity = 56%, specificity = 100%, area under the curve = 0.86).

INTERPRETATION

BabyOSCAR scores are predictors of diagnosis, body distribution, and future gross motor function in infants with spastic CP at 2 years of age or later.

WHAT THIS PAPER ADDS

Decreased independent joint movement at 3 months predicts spastic cerebral palsy (CP) at 2 years. Baby Observational Selective Control AppRaisal (BabyOSCAR) scores ≤13 are predictive of Gross Motor Function Classification System (GMFCS) levels III to V. BabyOSCAR scores of 14 to 22 are predictive of GMFCS levels I and II. A BabyOSCAR total asymmetry score >5 predicts unilateral CP. Stereotyped movements are more prominent in those who will be diagnosed with spastic CP at 2 years.

Baby Observational Selective Control AppRaisal (BabyOSCAR): Construct validity and test performance

AIM

To investigate the construct validity of the Baby Observational Selective Control AppRaisal (BabyOSCAR), an assessment of independent joint motion in infants with cerebral palsy (CP).

METHOD

BabyOSCAR was scored for 75 infants (45 with CP and 30 without CP). Rasch analysis was used in combination with classical test theory to assess areas of strength or improvement. Overall fit and precision, unidimensionality, local independence, reliability indices, Wright's child-item map, and differential item functioning were examined as part of Rasch analysis to investigate the item properties, internal construct validity, and reliability of BabyOSCAR. Cronbach's α was used to evaluate items' internal consistency.

RESULTS

Analysis demonstrated good fit to the Rasch model, with only one erratic item. Unidimensionality results suggest two dimensions, split between arm and leg items. Item calibration reliability was between 0.84 and 0.86, with three distinct item difficulty levels. Infant measure reliability was between 0.82 and 0.91, separating infants into three ability levels. Together, the two subscales covered the full range of skills, with redundancy mostly between the same motion on both sides of the body. Cronbach's α was between 0.90 and 0.95.

INTERPRETATION

BabyOSCAR's construct validity was supported. Arm and leg subscales can be translated to a logit scale.

WHAT THIS PAPER ADDS

Baby Observational Selective Control AppRaisal (BabyOSCAR) has excellent construct validity with good overall fit and precision. Individual BabyOSCAR items contribute and work well together, forming an interval-level assessment. BabyOSCAR has two separate subscales, arms and legs, that complement each other. BabyOSCAR's items represent a continuum of skills with three distinct difficulty levels. BabyOSCAR's continuum of skills reliably separates infants into three ability levels.

Baby Observational Selective Control AppRaisal (BabyOSCAR): Convergent and discriminant validity and reliability in infants with and without spastic cerebral palsy

AIM

To describe the development of an observational measure of spontaneous independent joint motion in infants with spastic cerebral palsy (CP), the Baby Observational Selective Control AppRaisal (BabyOSCAR), and to test its convergent validity and reliability.

METHOD

A retrospective sample of 75 infants (45 with spastic CP and 30 without CP) at 3 months of age were scored with the BabyOSCAR and compared with diagnosis of spastic CP, limbs affected, and Gross Motor Function Classification level at 2 years of age or later for convergent validity using t-tests, Kruskal-Wallis tests, and Spearman's rank correlation coefficients. BabyOSCAR interrater and test-retest reliability was also evaluated using intraclass correlation coefficients.

RESULTS

Infants with spastic CP had significantly lower BabyOSCAR scores than children without CP (p < 0.001) and scores were significantly correlated with Gross Motor Function Classification System levels (p < 0.001). Children with unilateral CP had significantly higher asymmetry scores than children with bilateral CP or no CP (p < 0.01). Interrater and test-retest reliabilities were good to excellent.

INTERPRETATION

Reductions in independent joint control measured in infancy are a hallmark of eventual diagnosis of spastic CP, and influence gross motor function later in childhood (with or without a diagnosis of CP).

WHAT THIS PAPER ADDS

Early brain injury causing spastic cerebral palsy results in fewer independent joint movements in infants. Baby Observational Selective Control AppRaisal (BabyOSCAR) score at 3 months depends on limbs affected by early brain injury. BabyOSCAR scores at 3 months correlate with Gross Motor Function Classification System level at ≥2 years. BabyOSCAR has excellent interrater reliability. BabyOSCAR, scored with a 1-minute video recording, has good to excellent test-retest reliability.

Telehealth of Infants at Risk During the COVID-19 Pandemic: Physical Therapists' and Caregiver's Perceptions and Costs

AIM

We aimed to describe telehealth used to detect infants at risk of neurodevelopmental delay and assess the assessors' and caregivers' perceptions and costs.

METHODS

This was an observational study in which five physical therapists applied the General Movement Assessment, the neurological exam based on the Hammersmith Infant Neurological Examination, and the Alberta Infant Motor Scale via telehealth in 65 infants at risk of neurologic delay during the COVID-19 pandemic. The perceptions of assessors and caregivers were assessed using a questionnaire. We tabulated the family's costs (internet access) and the therapist's expenses (internet access and professional fees).

RESULTS

In general, assessors felt comfortable and reported good quality of teleassessment. They highlighted the significant effort they and caregivers required for synchronous methods, challenges in clearly guiding caregivers on infant positioning, difficulties in adjusting the camera's position, and unstable internet connections. Most assessors expressed a willingness to continue using telehealth. Caregivers displayed high satisfaction, and the costs were minimal.

CONCLUSION

Teleassessment during the COVID-19 pandemic was feasible, although implementing this method of health service in general clinical practice still requires further scrutiny.

Effectiveness of early diagnosis of cerebral palsy guideline implementation: a systematic review

INTRODUCTION

Tailored implementation interventions are required to overcome the diagnostic research-practice gap for cerebral palsy (CP). Evaluating the impact of interventions on patient outcomes is a priority. This review aimed to summarize the established evidence for the effectiveness of guideline implementations in lowering the age of CP diagnosis.

EVIDENCE ACQUISITION

A systematic review was conducted according to PRISMA. CINAHL, Embase, PubMed and MEDLINE were searched (2017-October 2022). Inclusion criteria were studies that evaluated effect of CP guideline interventions on health professional behaviour or patient outcomes. GRADE was used to determine quality. Studies were coded for use of theory (Theory Coding Scheme). Meta-analysis was performed and a standardized metric used to summarize statistics of intervention effect estimates.

EVIDENCE SYNTHESIS

Of (N.=249) records screened, (N.=7) studies met inclusion, comprising interventions following infants less than 2 years of age with CP risk factors (N.=6280). Guideline feasibility in clinical practice was established through health professional adherence and patient satisfaction. Efficacy of patient outcome of CP diagnosis by 12 months of age was established in all studies. Weighted averages were: (1) high-risk of CP (N.=2) 4.2 months and (2) CP diagnosis (N.=5) at 11.6 months. Meta-analysis of (N.=2) studies found a large, pooled effect size Z = 3.00 (P=0.003) favoring implementation interventions lowering age of diagnosis by 7.50 months, however study heterogeneity was high. A paucity of theoretical frameworks were identified in this review.

CONCLUSIONS

Multifaceted interventions to implement the early diagnosis of CP guideline are effective in improving patient outcomes by lowering the age of CP diagnosis in high-risk infant follow-up clinics. Further targeted health professional interventions including low-risk infant populations are warranted.

Identifying Opportunities for Early Detection of Cerebral Palsy

This study aimed to evaluate assessment and referral practices for the early detection and diagnosis of children at risk for or with cerebral palsy (CP) by health care and education providers in Maryland and Delaware. A secondary aim was to identify barriers for using early detection tools and identify opportunities for change to support early diagnosis and improve care. Seventy-two participants answered ≥ 50% of the survey questions. Most were occupational or physical therapists (86%) working in early intervention (61%). Eighty-eight percent indicated awareness that CP can be diagnosed by 12 months. Though 86% stated they typically suspect a diagnosis of CP between 0 and 12 months, only 19% reported that their patients received a CP diagnosis < 12 months. The Developmental Assessment of Young Children (73%) and the Peabody Developmental Motor Scales-2 (59%) were used most. Many respondents indicated never using magnetic resonance imaging (70%), the General Movements Assessment (87%), or the Hammersmith Infant Neurological Exam (69%). Participants identified clinical signs and symptoms prompting a referral for the diagnostic assessment of CP, most commonly stiffness in legs (95%), excessive head lag (93%), and persistent fisting (92%). Policy and organizational change, clinician education, and training are needed to support the implementation of CP early detection guidelines.

Optimizing trajectories of social adaptive competencies after extreme prematurity during the first 1000 days

Over 75% of surviving extremely preterm infants do not have major neurodevelopmental disabilities; however, more than half face difficulties with communication, coordination, attention, learning, social, and executive function abilities. These "minor" challenges can have a negative impact on educational and social outcomes, resulting in physical, behavioral, and social health problems in adulthood. We will review assessment tools for social-emotional and adaptive functional skills in early childhood as these determine family and early childhood supports. We highlight bronchopulmonary dysplasia as an example of the critical intersections of parental wellbeing, medical and developmental adaptive trajectories in infancy and early childhood, and partnerships between child neurologists and community medical and developmental professionals. We examine studies of engaging parents to promote developmental trajectories, with a focus on supporting parent-child interactions that underlie communication, social-adaptive behaviors, and learning in the first 1000 days of life. Recommendations for neurodevelopmental surveillance and screening of extremely preterm infants can also be applied to infants with other risk factors for altered neurodevelopment.

Reliability, Knowledge Translation, and Implementability of the Spanish Version of the Hammersmith Infant Neurological Examination

Purpose. This study aimed to: (a) translate and cross-culturally adapt the Hammersmith Infant Neurological Examination (HINE) into Spanish; (b) evaluate its intra- and inter-examiner reliability; (c) support a knowledge translation and tool implementation program in early intervention; and (d) evaluate its reliability and implementation for professionals one year after receiving training. Materials and methods. The translation followed the World Health Organization's recommendations. Reliability was assessed in 25 infants aged between 3 and 15 months with identifiable risks of cerebral palsy (CP). The implementation was also evaluated by analyzing the reliability of professionals without previous experience of the tool by using a pre-survey and a follow-up survey one year after training. The survey covered aspects related to the use of early detection tools of CP and the use of HINE, including attitudes, opinions, and perceptions. Results. An excellent intra- and inter-examiner agreement was obtained for the total score of the HINE intra-class correlation coefficient (ICC = 0.98 in both indices). One year after training, the professionals also showed excellent reliability values (ICC = 0.99), as well as an increase in sensitization and skills in evidence-based practices for the early detection of "high risk" of CP. Conclusions. The Spanish version of HINE is a reliable measure for the neurological evaluation of "high risk" of CP and can be administered after standardized training and without costs to acquire the evaluation. This allows its accessible and widespread implementation in the clinical context.

F-words e ingredientes das intervenções precoces para crianças com paralisia cerebral não deambuladoras: uma revisão de escopo

Os ingredientes de tecnologia assistiva podem promover várias F-words (funcionalidade, saúde, família, diversão, amigos e futuro). O menor nível de evidência foi encontrado para diversão, amigos e futuro. Outros fatores (prestação de serviços, treinamento profissional, dose de terapia, modificações ambientais) são relevantes para crianças pequenas nos níveis IV e V do GMFCS. Esta revisão de escopo identificou os ingredientes de intervenções precoces para crianças com paralisia cerebral em risco de não serem deambuladoras, e os mapeou-os de acordo com a estrutura das F-words. O treinamento formal dos pais e a tecnologia assistiva se destacaram como estratégias para abordar com várias F-words.

F-words and early intervention ingredients for non-ambulant children with cerebral palsy: A scoping review

AIM

To explore the ingredients of early interventions provided to young children with cerebral palsy (CP) who are classified in Gross Motor Function Classification System (GMFCS) levels IV and V, and to identify the 'F-words' addressed by the interventions.

METHOD

Searches were completed in four electronic databases. Inclusion criteria were the original experimental studies that fitted the following PCC components: population, young children (aged 0-5 years, at least 30% of the sample) with CP and significant motor impairment (GMFCS levels IV or V, at least 30% of the sample); concept, non-surgical and non-pharmacological early intervention services measuring outcomes from any of the International Classification of Functioning, Disability and Health domains; and context, studies published from 2001 to 2021, from all settings and not limited to any specific geographical location.

RESULTS

Eighty-seven papers were included for review, with qualitative (n = 3), mixed-methods (n = 4), quantitative descriptive (n = 22), quantitative non-randomized (n = 39), and quantitative randomized (n = 19) designs. Fitness (n = 59), family (n = 46), and functioning (n = 33) ingredients were addressed by most experimental studies, whereas studies on fun (n = 6), friends (n = 5), and future (n = 14) were scarce. Several other factors (n = 55) related to the environment, for example, service provision, professional training, therapy dose, and environmental modifications, were also relevant.

INTERPRETATION

Many studies positively supported formal parent training and use of assistive technology to promote several F-words. A menu of intervention ingredients was provided, with suggestions for future research, to incorporate them into a real context within the family and clinical practice.

WHAT THIS PAPER ADDS

Family-centred care (including coaching and caregiver-delivered interventions) and formal parental training are effective strategies for children in GMFCS levels IV and V. Assistive technology ingredients (power, mobility, supported, sitting, stepping, and standing) may promote several 'F-words' (functioning, fitness, family, fun, friends, and future). The lowest level of evidence was found for fun, friends, and future. Other factors (service provision, professional training, therapy dose, environmental modifications) are relevant for young children in GMFCS levels IV and V.

A Call for Early Detection of Cerebral Palsy

Cerebral palsy (CP) is the most common physical disability across the lifespan, but historically, CP has not been diagnosed before the age of 2 years. Barriers to early diagnosis ranged from lack of available biomarkers, absence of curative treatments, perceived stigma associated with a lifelong diagnosis, and a desire to rule out other diagnoses first. Most importantly, the fundamental question that remained was whether children would benefit from earlier detection and intervention given the paucity of research. However, evidence-based guidelines published in 2017 demonstrated that the General Movements Assessment, the Hammersmith Infant Neurological Examination, and neuroimaging can be combined with other elements such as a clinical history and standardized motor assessments to provide the highest predictive value for diagnosing CP as early as age 3 months in high-risk newborns. Implementation of these guidelines has been successful in decreasing the age at CP diagnosis, particularly in high-risk infant follow-up clinics with expertise in performing these assessments. Early detection of CP allows for clinical and research opportunities investigating earlier interventions during a critical period of neuroplasticity, with the goal of improving developmental trajectories for children and their families. New guidelines and research are now being developed with a focus on early, targeted interventions that continue to be studied, along with global detection initiatives.

A randomized-controlled trial of parent-administered interventions to improve short-term motor outcomes in hospitalized very low birthweight infants

BACKGROUND

Premature infants are at increased risk for cerebral palsy (CP). Early interventions with a motor focus and administered by parents may improve motor outcomes.

AIMS

Secondary study evaluating the short-term motor outcomes and risk for CP in very low birthweight (VLBW) infants randomized to multimodal interventions with a motor focus provided by parents versus usual care.

STUDY DESIGN

Randomized controlled trial (intervention vs. usual care (control group)).

SUBJECTS

Infants (<32 weeks' gestational age (GA) and/or <1500 grams birthweight) born between March 2019 and October 2020.

OUTCOME MEASURES

Short-term motor outcomes and risk for CP was evaluated using the Hammersmith Infant Neurological Evaluation (HINE, primary motor outcome), the General Movement Assessment (GMA) and the Test of Infant Motor Performance (TIMP) at 3 months' postmenstrual age (PMA).

RESULTS

70 participants were enrolled (GA 28.3±2.7 weeks, birthweight 1139.2±376.6 grams, 64.3% male). The in-person follow-up rate was 73%, lower than expected, in part due to COVID-19 restrictions, resulting in 25 infants (intervention) and 26 infants (control) with outcome data available for analysis. There was not a significant difference in the HINE, GMA or TIMP at 3 months' PMA between groups.

CONCLUSION

Multimodal interventions with a motor focus and provided by parents need further investigation to determine if they can improve short-term motor outcomes in VLBW infants. These interventions are evidence-based and the evaluation of broader implementation into routine care is also needed.

Effects of caffeine therapy for apnea of prematurity on sleep and neurodevelopment of preterm infants at 6 months of corrected age

STUDY OBJECTIVES

To determine the differences in sleep patterns between preterm infants who received caffeine and those who did not and to evaluate the effects of caffeine therapy on early neurodevelopment. Secondarily, actigraphy and polysomnography were compared to evaluate the sleep of preterm infants.

METHODS

Twenty-eight preterm infants ages 28-34 weeks admitted to a single-center Level III neonatal intensive care unit between May 2020 and May 2021 were included. Sleep was assessed by actigraphy for 72 hours with Respironics Mini-Mitter® Actiwatch-2 and Brief Infant Sleep Questionnaire at 6 months corrected age. On the first day of actigraphy, infants underwent polysomnography between 10:00 am and 3:00 pm. Neurodevelopment was evaluated by the Bayley Scales of Infant and Toddler Development-III, the Ages & Stages Questionnaire, and the Hammersmith Infant Neurological Examination.

RESULTS

There were no significant differences in sleep parameters measured by actigraphy, the Brief Infant Sleep Questionnaire, and polysomnography between infants in the caffeine group (n = 12) and no-caffeine group (n = 16). Sensitivity (91.07%) and agreement rate (77.21%) for the actigraphy against polysomnography were highest at the automatic threshold. No significant differences were observed in the neurodevelopment of infants in the caffeine group compared to the no-caffeine group.

CONCLUSIONS

Sleep parameters and neurodevelopmental outcomes were not different in infants at 6 months of corrected age with regard to caffeine therapy. Actigraphy at the automatic threshold can be used in infants for sleep pattern assessment.

Cerebral Palsy - Early Diagnosis and Intervention Trial: protocol for the prospective multicentre CP-EDIT study with focus on diagnosis, prognostic factors, and intervention

BACKGROUND

Early diagnosis of cerebral palsy (CP) is important to enable intervention at a time when neuroplasticity is at its highest. Current mean age at diagnosis is 13 months in Denmark. Recent research has documented that an early-diagnosis set-up can lower diagnostic age in high-risk infants. The aim of the current study is to lower diagnostic age of CP regardless of neonatal risk factors. Additionally, we want to investigate if an early intervention program added to standard care is superior to standard care alone.

METHODS

The current multicentre study CP-EDIT (Early Diagnosis and Intervention Trial) with the GO-PLAY intervention included (Goal Oriented ParentaL supported home ActivitY program), aims at testing the feasibility of an early diagnosis set-up and the GO-PLAY early intervention. CP-EDIT is a prospective cohort study, consecutively assessing approximately 500 infants at risk of CP. We will systematically collect data at inclusion (age 3-11 months) and follow a subset of participants (n = 300) with CP or at high risk of CP until the age of two years. The GO-PLAY early intervention will be tested in 80 infants with CP or high risk of CP. Focus is on eight areas related to implementation and perspectives of the families: early cerebral magnetic resonance imaging (MRI), early genetic testing, implementation of the General Movements Assessment method, analysis of the GO-PLAY early intervention, parental perspective of early intervention and early diagnosis, early prediction of CP, and comparative analysis of the Hand Assessment for Infants, Hammersmith Infant Neurological Examination, MRI, and the General Movements method.

DISCUSSION

Early screening for CP is increasingly possible and an interim diagnosis of "high risk of CP" is recommended but not currently used in clinical care in Denmark. Additionally, there is a need to accelerate identification in mild or ambiguous cases to facilitate appropriate therapy early. Most studies on early diagnosis focus on identifying CP in infants below five months corrected age. Little is known about early diagnosis in the 50% of all CP cases that are discernible later in infancy. The current study aims at improving care of patients with CP even before they have an established diagnosis.

Constructing validity evidence from a pilot key-features assessment of clinical decision-making in cerebral palsy diagnosis: application of Kane's validity framework to implementation evaluations

BACKGROUND

Physician decision-making skills training is a priority to improve adoption of the cerebral palsy (CP) clinical guideline and, through this, lower the age of CP diagnosis. Clinical guideline implementation aims to improve physician practice, but evaluating meaningful change is complex. Limitations in the validity evidence of evaluation instruments impact the evidence base. Validity frameworks, such as Kane's, enable a targeted process to gather evidence for instrument scores, congruent to context and purpose. Yet, application of argument-based methodology to implementation validation is rare. Key-features examination methodology has established validity evidence supporting its use to measure decision-making skills, with potential to predict performance. We aimed to apply Kane's framework to evaluate a pilot key-features examination on physician decision-making in early CP diagnosis.

METHODS

Following Kane's framework, we evaluated evidence across inferences of scoring, generalisation, extrapolation and implications in a study design describing the development and pilot of a CP diagnosis key-features examination for practising physicians. If found to be valid, we proposed to use the key-feature scores as an outcome measure of decision-making post education intervention to expedite CP diagnosis and to correlate with real-world performance data to predict physician practice.

RESULTS

Supporting evidence for acceptance of scoring inferences was achieved through examination development with an expert group (n = 10) and pilot results (n = 10): (1) high internal consistency (0.82); (2) acceptable mean item-discrimination (0.34); and (3) acceptable reliability of examination scorers (95.2% congruence). Decreased physician acceptance of examination time (70%) was identified as a threat and prioritised in case reduction processes. Partial acceptance of generalisation, extrapolation and implications inferences were defensible with: (1) accumulated development evidence following established key-features methodology; (2) high pilot acceptance for authenticity (90%); and (3) plausibility of assumptions of score correlation with population register data.

CONCLUSIONS

Kane's approach is beneficial for prioritising sources of validity evidence alongside the iterative development of a key-features examination in the CP field. The validity argument supports scoring assumptions and use of scores as an outcome measure of physician decision-making for CP guideline education implementation interventions. Scoring evidence provides the foundation to direct future studies exploring association of key-feature scores with real-world performance.

Evaluation of the impact of continuous Kangaroo Mother Care (KMC) initiated immediately after birth compared to KMC initiated after stabilization in newborns with birth weight 1.0 to < 1.8 kg on neurodevelopmental outcomes: Protocol for a follow-up study

BACKGROUND

Preterm birth or low birth weight is the single largest cause of death in newborns, however this mortality can be reduced through newborn care interventions, including Kangaroo Mother Care (KMC). Previously, a multi-country randomized controlled trial, coordinated by the World Health Organization (WHO), reported a significant survival advantage with initiation of continuous KMC immediately after birth compared with initiation of continuous KMC a few days after birth when the baby is considered clinically stable. Whether the survival advantage would lead to higher rates of neurodevelopmental morbidities, or the immediate KMC will also have a beneficial effect on cognitive development also, has not been investigated. We therefore propose to test the hypothesis that low-birth-weight infants exposed to immediate KMC will have lower rates of neurodevelopmental impairment in comparison to traditional KMC-treated infants, by prospectively following up infants already enrolled in the immediate KMC trial for the first 2 years of life, and assessing their growth and neurodevelopment.

METHODS

This prospective cohort study will enroll surviving neonates from the main WHO immediate KMC trial. The main trial as well as this follow-up study are being conducted in five low- and middle-income countries in South Asia and sub-Saharan Africa. The estimated sample size for comparison of the risk of neurodevelopmental impairment is a total of 2200 children. The primary outcome will include rates of cerebral palsy, hearing impairment, vision impairment, mental and motor development, and epilepsy and will be assessed by the age of 3 years. The analysis will be by intention to treat.

DISCUSSION

Immediate KMC can potentially reduce low-birth-weight-associated complications such as respiratory disease, hypothermia, hypoglycemia, and infection that can result in impaired neurocognitive development. Neuroprotection may also be mediated by improved physiological stabilization that may lead to better maturation of neural pathways, reduced risk of hypoxia, positive parental impact, improved sleep cycles, and improved stress responses. The present study will help in evaluating the overall impact of KMC by investigating the long-term effect on neurodevelopmental impairment in the survivors.

Assessing the Utility of Neonatal Screening Assessments in Early Diagnosis of Cerebral Palsy in Preterm Infants

Background: Early diagnosis of cerebral palsy (CP) in high-risk infants is possible at 3−4 months’ corrected age (CA) using standardised assessments. Aim: To assess the utility of neonatal screening assessments—writhing general movements (GMs) and the Hammersmith Neonatal Neurological Examination (HNNE)—to predict CP/high-risk status at 3−4 months’ CA in extremely preterm infants. Methods: Retrospective cohort study of high-risk preterm infants (born < 29 weeks’ gestation and/or birth weight < 1000 g) attending an Early Neurodevelopment Clinic. Data from neonatal assessments were compared with CP/high-risk diagnosis at 3−4 months’ CA, fidgety GMs, and Hammersmith Infant Neurological Examinations (HINE) using logistic regression, linear regression, and Spearman rank correlation. Results: Two hundred and two preterm infants (median gestation age at birth 27.3 (IQR 25.4−28.3) weeks, mean birth weight 870.3 (SD 248.4) grams) were included. A total of 26 (12.8%) infants received early CP/high-risk diagnoses at 3−4 months’ CA. A lower gestational age (GA) (OR = 0.78; p = 0.029, 95% CI [0.26, 0.97]) and abnormal writhing GMs (OR 1.56; p = 0.019, 95% CI [1.07, 2.27]) were predictive of CP/high-risk diagnosis. Although after adjustment for sex, GA, birth weight, and growth restriction, GA (aOR = 0.67; p = 0.068, 95% CI [0.44, 1.03]) and writhing GMs (aOR = 1.44; p = 0.087, 95% CI [0.95, 2.20]) were not significant, a strong trend still persisted. The HNNE scores significantly correlated with both the HINE evaluation (rs = 0.43, p < 0.001, 95% CI [0.31, 0.56]) and fidgety GMs (rs = −0.10, p = 0.012, 95% CI [−0.32, −0.04]). Linear regression confirmed the HNNE was highly predictive of the HINE (correlation coefficient 0.82; p < 0.001, 95% CI [0.48, 1.15]). Writhing GMs did not significantly correlate with either fidgety GMs (p = 0.723, 95% CI [−0.12, 0.17]) or the HINE (p = 0.173, 95% CI [−0.24, 0.04]). Conclusions: Abnormal writhing GMs in the neonatal period were non-significantly associated with early CP/high-risk diagnoses in extremely preterm infants in a multivariate analysis. Additionally, the HNNE significantly correlated with both fidgety GMs and the HINE.

Accuracy of the Hammersmith infant neurological examination for the early detection of neurological changes in infants exposed to Zika virus: A case-cohort study

The Hammersmith infant neurological examination (HINE) is a highly predictive tool for the easy and low-cost detection of cerebral palsy. Between 2015 and 2016, the rapid spread of the Zika virus (ZIKV) in Brazil was responsible for an increase in microcephaly cases. This study aimed to verify the accuracy of the HINE for the early detection of neurological problems in Brazilian babies exposed to ZIKV.This was a cross sectional case-control study of children exposed to ZIKV. This study was part of the Jundiaí ZIKV Cohort. Of a total sample of 782 children, 98 were evaluated (26 in the exposed group and 63 in the control group). We included late preterm infants and term infants who were exposed to the ZIKV and were participants in the ZIKV Cohort study. Student's t-test and stepwise multivariate logistic regression were used to compare groups.Of the 26 items evaluated in the five scored categories of the HINE (cranial nerve function, posture, movements, tone, reflexes, and reactions), only the difference in ankle dorsiflexion between the exposed and the control groups was statistically significant. However, some items showed a significant trend in relation to the control group.Our results demonstrated the importance of early neurological assessment of infants exposed to ZIKV, even in those without a microcephaly diagnosis.

Deep learning-based quantitative analyses of spontaneous movements and their association with early neurological development in preterm infants

This study aimed to develop quantitative assessments of spontaneous movements in high-risk preterm infants based on a deep learning algorithm. Video images of spontaneous movements were recorded in very preterm infants at the term-equivalent age. The Hammersmith Infant Neurological Examination (HINE) was performed in infants at 4 months of corrected age. Joint positional data were extracted using a pretrained pose-estimation model. Complexity and similarity indices of joint angle and angular velocity in terms of sample entropy and Pearson correlation coefficient were compared between the infants with HINE < 60 and ≥ 60. Video images of spontaneous movements were recorded in 65 preterm infants at term-equivalent age. Complexity indices of joint angles and angular velocities differed between the infants with HINE < 60 and ≥ 60 and correlated positively with HINE scores in most of the joints at the upper and lower extremities (p < 0.05). Similarity indices between each joint angle or joint angular velocity did not differ between the two groups in most of the joints at the upper and lower extremities. Quantitative assessments of spontaneous movements in preterm infants are feasible using a deep learning algorithm and sample entropy. The results indicated that complexity indices of joint movements at both the upper and lower extremities can be potential candidates for detecting developmental outcomes in preterm infants.

Effectiveness of Bedside Clinical Screening Tools in Predicting Short-Term Neurodevelopmental Delay Among Very-Low-Birth-Weight Pre-terms: A Prospective Observational Study

Background: Pre-term births are associated with increased risk of various morbidities, especially neurological. Early detection and early intervention to prevent these morbidities will have immediate and long-term benefits to the individuals and society at large. However, the screening and assessment tools, including both clinical and radiological, are not uniformly available in resource-poor settings. The present study was carried out to evaluate the validity of the clinical screening tools for detecting neurodevelopmental delay among very-low-birth-weight (VLBW) pre-term babies.

Methods: This prospective observational study was undertaken in the child development unit of a tertiary care hospital from July 2015 to October 2017. All pre-term VLBW neonates admitted in level III Neonatal Intensive Care within the first 24 hours of life were included in the study. They were subjected to Hammersmith Neonatal Neurological Examination (HNNE) and magnetic resonance imaging (MRI) of brain at term-equivalent age. Subsequently, the same group was followed up with Amiel-Tison (AT) angles, Child Development Centre (CDC) grading for sitting developed at Trivandrum, Kerala, India, and Denver Development Screening Test (DDST-II gross motor) at eight months corrected age, and their outcomes were analyzed.

Results: 17.9% of the ex-preterm were abnormal as per HNNE evaluation at term-corrected age. At short-term follow-up screening, 13.8% were found to be abnormal based on AT angles, while 35.2% were found to be abnormal as per CDC grading and 30.4% were found to have risk for delay as per DDST-II (gross motor). A high level of sensitivity (93.6%) and positive predictive value (91.2%) was observed for HNNE at term equivalent with MRI brain assessment considered as gold standard. Among the follow-up screening tools, CDC grading for sitting, AT angles, and DDST-II had high sensitivity (>85%).

Conclusion: The combination of HNNE along with radiological assessment at term-corrected age can be considered as appropriate for predicting long-term neurodevelopmental outcome in VLBW pre-term infants. During follow-up, simple tools like CDC grading for motor milestones, AT angles, and DDST-II may be utilized if facilities for standard assessment are not available as in resource-poor settings.

Heterogeneous development of children with Congenital Zika Syndrome-associated microcephaly

Objective

To describe the neurological and neurodevelopmental outcomes of children with Congenital Zika Syndrome (CZS) associated microcephaly beyond 2 years of age.

Method

We followed children with CZS-associated microcephaly in an outpatient clinic in Salvador, Brazil. Neurological and neurodevelopmental assessments were performed using the Hammersmith Infant Neurological Examination (HINE) and Bayley Scales of Infant and Toddler Neurodevelopment (Bayley-III) respectively.

Results

Of the 42 children included, 19 were male (45.2%); median (interquartile range) age at neurological evaluation was 28 (25–32) months, and 36 (85.7%) had severe microcephaly. HINE and Bayley-III results were completed for 35/42 (83.3%) and 33/42 (78.5%) children respectively. Bayley-III identified a severe developmental delay in 32/33 (97.0%) children while 1/33 (3.0%) had only a mild delay. In the multivariable analysis, we found that Bayley-III and HINE scores were correlated. Better HINE scores were associated with higher Bayley-III cognitive raw scores (β = 0.29; CI 95% = 0.02–0.57) and motor raw scores (β = 0.43; CI 95% = 0.04–0.82) after adjusting for head circumference, prematurity, and age at neurodevelopmental evaluation. Furthermore, we found that greater head circumference at follow up was associated with higher cognitive (β = 1.27; CI 95% = 0.01–2.53) and motor raw scores (β = 2.03; CI 95% = 0.25–3.81).

Conclusion

Children with CZS-associated microcephaly demonstrate severe neurodevelopmental delays and slower growth rates than their peers over time. Still, they have remarkably heterogeneous neurodevelopmental profiles according to neurological exam scores which correlate with their long-term outcomes. We found that HINE scores effectively captured the heterogeneity of neurological capabilities among these children and could be predictive of cognitive and motor development progress.

Assessment of Pain and Sleep Symptoms in Children at High Risk for Cerebral Palsy in a Pediatric Neurodevelopmental Clinic: Implications for Future Quality Improvement Interventions

Children with cerebral palsy (CP) often experience distressing symptoms. It is estimated that 3 in 4 have chronic pain and 1 in 5 have a sleep disorder, with the highest frequency and severity occurring in children with the greatest impairment. Sleep impairment and pain can adversely impact activities, participation and quality of life; however, prevalence of these symptoms in children at risk for CP < 2 years of age remain unknown. The objective of this project was to develop a baseline understanding of the presence of sleep and pain symptoms among children <2 years at high risk for CP to establish a baseline estimate for future quality improvement initiatives. A retrospective chart review was performed on a convenience sample of 50 children <2 years of age that were determined to be high risk for CP. This was determined through a standardized Hammersmith Infant Neurological Evaluation (HINE) global score of less than 56 performed as part of routine care. Descriptive statistics were used to explore the sample. A nonparametric test was used to evaluate the differences between groups. Pain and sleep problems were frequently reported in our sample (38% sleep problems and 32% pain). There were also significant differences between reported symptoms and the HINE. Reported symptoms were associated with lower HINE scores. Sleep and pain are frequent symptoms in children at risk for cerebral palsy. Early identification of these symptoms can lead to clinic-level intervention which may include pharmacological and non-pharmacological management strategies that improve outcomes for children at high risk for CP.

Early Intervention in Unilateral Cerebral Palsy: Let's Listen to the Families! What Are Their Desires and Perspectives? A Preliminary Family-Researcher Co-Design Study

Cerebral palsy (CP) is a clinical diagnosis based on a combination of clinical and neurological signs, which occurs between the ages of 12 and 24 months. Cerebral palsy or a high risk of cerebral palsy can be accurately predicted before 5-6 months, which is the corrected age. This would allow the initiation of intervention at an early stage. Parents must be more involved in the development and implementation of the early therapy, increasing opportunities for parent-child interaction. The aim of this study was to learn from the perspectives of families with children under 12 months with unilateral cerebral palsy (UCP), what ingredients (barriers and facilitators) should be involved in early intervention so that we could co-design (researchers and families) a multidisciplinary guideline for a global intervention addressed to the needs of the child and the family. Semi-structured interviews were conducted at a time and venue convenient for the families. A total of ten families with experience in early intervention were invited to attend the interview with open questions: (1) What components should early intervention have for a baby diagnosed with UCP? (2) What components should early intervention have for the family? (3) What should the involvement of the family be in early intervention? (4) What barriers included in early intervention should be removed? From the data analysis, three key topics emerged and were subsequently named by focus group participants: (1) UCP early intervention components, (2) family involvement in early intervention of UCP, and (3) removing barriers and creating facilitators within early intervention. The participation of the families (mothers) in the co-design of the necessary ingredients within the scope of a multidisciplinary early intervention guide aimed at children with UCP under 12 months allows learning about their reality and not that of the therapist. The following list highlights the present barriers as perceived by the parents: intervention as spectators, therapeutic goals, clinic environment, and lack of empathy, and the possible facilitators determined by the parents during the implementation comprised teamwork, the family's goals, motivation during the intervention, and learning at home. Thus, an early intervention program to improve global functionality should address family involvement through multidisciplinary coaching and the modification of the environment, encouraging family goals and family support through the family-therapist team.

Multisite Veno-Venous Cannulation for Neonates and Nonambulatory Children

OBJECTIVES

Neonates with respiratory failure are ideally supported with veno-venous rather than veno-arterial extracorporeal membrane oxygenation due to the reduced rate of neurologic complications. However, the proportion of neonates supported with veno-venous extracorporeal membrane oxygenation is declining. We report multisite veno-venous extracorporeal membrane oxygenation, accessing the neck, returning to the inferior vena cava via the common femoral vein in neonates and children less than 10 kg.

DESIGN

Retrospective case series with 1 year minimum follow-up.

PATIENTS

Patients less than 10 kg supported with veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein.

SETTING

A 30-bed pediatric intensive care delivering extracorporeal membrane oxygenation to approximately 20 children annually.

INTERVENTIONS

Veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein was delivered using two single lumen cannulae.

MEASUREMENTS AND MAIN RESULTS

January 2015 to August 2019, 11 patients underwent veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein with median weight of 3.6 kg (interquartile range 2.8-6.1 kg), and median corrected gestational age of 13 days (interquartile range, 2-175 d). The smallest patient weighed 2.1 kg. Seven patients had comorbidities. Extracorporeal membrane oxygenation was technically successful in all patients with median flows of 126 mL/kg/min (interquartile range, 120-138 mL/kg/min) and median arterial oxygenation saturation of 94% (interquartile range, 91-98%) at 24 hours. Nine survived to home discharge, and two were palliated. Common femoral vein occlusion was observed in all patients on ultrasound post decannulation. There was no clinical or functional deficit in the cannulated limb at follow-up, a minimum of 1 year post extracorporeal membrane oxygenation.

CONCLUSIONS

Veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein was performed safely in patients under 10 kg with the smallest patient weighing 2.1 kg. Although occlusion of the common femoral vein was observed in patients post decannulation, subsequent follow-up demonstrated no clinical implications. We challenge current practice that veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein cannot be performed in nonambulatory patients and suggest that this strategy is preferred over veno-arterial extracorporeal membrane oxygenation in infants requiring extracorporeal membrane oxygenation for respiratory failure.

Early micro- and macrostructure of sensorimotor tracts and development of cerebral palsy in high risk infants

Infants born very preterm (VPT) are at high risk of motor impairments such as cerebral palsy (CP), and diagnosis can take 2 years. Identifying in vivo determinants of CP could facilitate presymptomatic detection and targeted intervention. Our objectives were to derive micro‐ and macrostructural measures of sensorimotor white matter tract integrity from diffusion MRI at term‐equivalent age, and determine their association with early diagnosis of CP. We enrolled 263 VPT infants (≤32 weeks gestational age) as part of a large prospective cohort study. Diffusion and structural MRI were acquired at term. Following consensus guidelines, we defined early diagnosis of CP based on abnormal structural MRI at term and abnormal neuromotor exam at 3–4 months corrected age. Using Constrained Spherical Deconvolution, we derived a white matter fiber orientation distribution (fOD) for subjects, performed probabilistic whole‐brain tractography, and segmented nine sensorimotor tracts of interest. We used the recently developed fixel‐based (FB) analysis to compute fiber density (FD), fiber‐bundle cross‐section (FC), and combined fiber density and cross‐section (FDC) for each tract. Of 223 VPT infants with high‐quality diffusion MRI data, 14 (6.3%) received an early diagnosis of CP. The cohort's mean (SD) gestational age was 29.4 (2.4) weeks and postmenstrual age at MRI scan was 42.8 (1.3) weeks. FD, FC, and FDC for each sensorimotor tract were significantly associated with early CP diagnosis, with and without adjustment for confounders. Measures of sensorimotor tract integrity enhance our understanding of white matter changes that antecede and potentially contribute to the development of CP in VPT infants.

Mothers' perspectives on the influences shaping their early experiences with infants at risk of cerebral palsy in India

BACKGROUND

Accurate diagnosis of cerebral palsy (CP) high-risk status is now possible in infants less than six months corrected age. Parents play a central role in providing nurturing care and implementing early intervention approaches. To design interventions tailored to needs of parents and understand how to improve parental support, this study aimed to understand the influences shaping parent experiences with an infant at high-risk of CP in West Bengal, India.

METHODS AND PROCEDURES

This phenomenological qualitative study was conducted with parents of infants at high-risk of CP in West Bengal, India. Individual in-depth interviews explored experiences with health providers, supports for caregiving and challenges of parenting. Interviews were conducted in English with concurrent translation and analysed using thematic analysis.

OUTCOMES AND RESULTS

Main themes included: limited finances and social networks shape decisions and caregiving practices; trust in the formal health care system; views of disability including explanations for their infant's condition and expectations for the child's future, and everyday adaptations required to meet infants' needs.

CONCLUSIONS AND IMPLICATIONS

Low cost models of early intervention may alleviate the financial burden and stress on families. Dependence on health care professionals for care management is a barrier to family-delivered approaches to care.

Effects of intraventricular hemorrhage on white matter microstructural changes at term and early developmental outcomes in infants born very preterm

PURPOSE

Very preterm (VPT) infants are at high risk for motor and behavioral deficits. We investigated microstructural differences using diffusion tensor imaging (DTI) among VPT infants with different grades of intraventricular hemorrhage (IVH), their association with early motor function and temperament ratings, and the potential moderating effect of IVH severity on the above structure-function relations.

METHODS

Fifty-seven VPT (≤32 weeks gestational age) infants with IVH (Low Grade (Papile grading I/II): 42; High Grade (III/IV): 15) were studied. DTI was acquired between 39 and 44 weeks postmenstrual age and was analyzed using the tract-based spatial statistics approach. Early motor function and temperament were assessed at 3-month corrected age based on the Hammersmith Infant Neurological Examination (HINE) and Infant Behavioral Questionnaire - Revised, Short Version (IBQ-R-S), respectively.

RESULTS

Significantly lower fractional anisotropy and higher mean, axial, and/or radial diffusivity were found in VPT infants with High Grade IVH compared to Low Grade IVH (p < 0.05). Significant associations were found between DTI metrics and motor function in both IVH groups and between DTI and Fear temperament ratings in the High Grade IVH Group (all p < 0.05). IVH severity had a significant moderating effect on the relation between DTI and motor and Fear ratings (p < 0.05).

CONCLUSION

DTI is a sensitive neuroimaging biomarker providing a refined understanding of the impact and location of differing severities of IVH on the developing white matter of VPT infants. Early motor and behavioral outcomes are associated with microstructural changes that are influenced by severity of IVH.

A Maternal-Administered Multimodal Neonatal Bundle in Hospitalized Very Preterm Infants: A Pilot Study

BACKGROUND

Premature infants are at an increased risk for developing cerebral palsy (CP). Evidence-based strategies designed to promote healthy brain development and facilitate adaptation after brain injury in infants still admitted to the neonatal intensive care unit (NICU) represent a novel approach that may lead to improved long-term outcomes.

PURPOSE

To investigate the feasibility of a maternal-administered early intervention bundle in very preterm infants prior to NICU discharge.

METHODS

A pilot trial evaluating a maternal-administered NICU-based bundle of interventions in preterm infants (≤32 weeks' gestational age and/or ≤1500 g birth weight). The impact of the bundle on short-term developmental outcomes of infants, as well as maternal stress, anxiety, and depression, is evaluated.

RESULTS

The intervention bundle was implemented in 11 mother-infant dyads (including 1 set of twins) for a median of 8 weeks and was overall well received. Vocal soothing, scent exchange, and comforting touch were feasible, performed at or above the predetermined goal of 71% of the time (5/7 days), while kangaroo care and infant massage were not. Maternal stress, anxiety, and depression were decreased during the study time.

IMPLICATIONS TO PRACTICE

A neonatal multimodal intervention bundle provided by mothers is feasible.

IMPLICATIONS TO RESEARCH

Additional randomized controlled studies are needed to determine whether this type of bundled interventions can (1) improve the neurodevelopmental outcomes of participating infants and (2) improve long-term parental outcomes, including decreased burden of anxiety and depression, as well as improved attachment and optimal patterns of social interaction.

Feasibility Analysis of CareToy-Revised Early Intervention in Infants at High Risk for Cerebral Palsy

Infants with perinatal brain injury are at high risk for Cerebral Palsy (CP). Progresses in detection of early signs of brain injury and of CP allow early intervention (EI) programs for improving the outcome of these infants. CareToy system (CT), developed within a European project (Trial Registration: NCT01990183), allows providing, by means of tele-rehabilitation, a highly personalized, family-centered, home-based EI for young infants, remotely managed by clinicians. CareToy, already used with pre-terms without brain injury, has been adapted for high-risk infants in a project funded by the Italian Ministry of Health, and the CareToy-Revised (CareToy-R) has been realized (Trial registration: NCT03211533 and NCT03234959). Before assessing its efficacy, it was crucial to evaluate the acceptability, usability, and feasibility of CareToy-R EI. Nineteen high-risk infants with perinatal brain injury, aged 5.95 ± 2.13 months (range 3.12–10.78 months), carried out an 8-week training with CareToy-R at home, performing customized playful activities with their parents, tailored to their rehabilitative needs, remotely managed by clinicians. The feasibility of training and study procedures was assessed through criteria derived from literature; acceptability and usability have been analyzed from data about individual training and an ad hoc questionnaire. All CareToy-R trainings were planned by the clinical staff with a daily personalized use for each infant between 30 and 45 min (mean 34.37 min). The amount of executed training by the infants was very high (daily mean 30.30 min), with no differences related to infant age, sex, and gestational age. All the nine feasibility criteria were achieved, family compliance to the project was very good, data collection was completed and the CareToy-R system worked properly and easily for parents. The answers to the questionnaire had a total mean score of 84.49% and they ranged from a minimum of 81.05% (in “easy to use” area) to a maximum of 86.49% (“changes due to the training” area), with no differences related to nationality or familiarity with technology of the mothers. This study reports preliminary evidence to the feasibility of a home-based EI with CareToy-R system in infants at high risk for CP. Results of the RCT will provide data about the potential effectiveness of this approach.

Cerebral Palsy in Children With Congenital Zika Syndrome: A 2-Year Neurodevelopmental Follow-up

OBJECTIVE

To describe the 2-year neurodevelopmental outcome in children with cerebral palsy associated with congenital Zika (CZ) and explore variables associated with a more severe presentation.

METHODS

Data on 69 children with cerebral palsy associated with CZ, followed in a neurorehabilitation hospital, who consecutively attended the neurodevelopmental assessment at 2 years of age, were collected. Bayley III Scales of Infant and Toddler Development, Hammersmith Infant Neurological Examination, and Gross Motor Function Classification System were used for the outcome evaluation. Descriptive and inferential statistical analysis were performed.

RESULTS

The median age at follow-up was of 24.0 (23-32) months. Only 3 (4.3%) children were not microcephalic. The majority presented with bilateral (94.2%), spastic (100.0%), Gross Motor Function Classification System grade IV or V (92.8%) cerebral palsy, epilepsy (73.1%), extremely low performances on cognitive (94.2%), language (95.7%), and motor (95.7%) Bayley-III Scales of Infant and Toddler Development Test scores. The median Hammersmith Infant Neurological Examination score was of 21.0 (range 9-75). There was a correlation between birth head circumference with the cognitive (r = 0.3, P < .01), language (r = 0.3, P < .01), and motor (r = 0.3, P < .01) Bayley-III Scales of Infant and Toddler Development Test scores, as well as with the Hammersmith Infant Neurological Examination score (r = 0.2, P < .03). An association was observed between an inferior median Hammersmith Infant Neurological Examination score with congenital microcephaly (P = .04), arthrogryposis (P = .02), and epilepsy in the first year (P < .01).

CONCLUSION

Cerebral palsy related to CZ presents with a severe global impairment at a 2-year follow-up. Birth head circumference, arthrogryposis, and early epilepsy are associated with a worse outcome and may be considered as prognostic markers. These findings are important for the neurorehabilitation planning, parents' guiding, and future prognostic studies.

Early Diagnosis and Classification of Cerebral Palsy: An Historical Perspective and Barriers to an Early Diagnosis

Since the 1800s, there have been calls in the literature for the early diagnosis of cerebral palsy (CP). However, diagnosis still often occurs late, from 12 to 24 months in high income countries and as late as 5 years in low resource settings. This is after the optimal timeframe for applying interventions which could harness neuroplastic potential in the developing brain. Multiple barriers exist which affect clinicians' confidence in diagnosing CP early. These range from the lack of definitive biomarkers to a lack of curative treatments for CP. Further barriers to diagnosis are proposed including; (a) difficulty finding a congruent fit with the definition of CP in an infant, where expected activity limitations might not yet be apparent; and (b) differences in the presentation of motor type and topography classifications between infants and children. These barriers may affect a clinicians' confidence using "pattern recognition" in the differential diagnosis process. One of the central tenets of this paper is that diagnosis and classification are different, involving different instruments, and are more accurately conducted separately in infants, whereas they are fundamentally interconnected in older children and inform therapeutic decisions. Furthermore, we need to be careful not to delay early diagnosis because of the low reliability of early classification, but instead uncouple these two processes. Ongoing implementation of best practice for early detection requires creative solutions which might include universal screening for CP. Implementation and accompanying knowledge translation studies are underway to decrease the average age of diagnosis in CP.

Delayed childhood neurodevelopment and neurosensory alterations in the second year of life in a prospective cohort of ZIKV-exposed children

We report neurodevelopmental outcomes in 216 infants followed since the time of PCR-confirmed maternal Zika virus (ZIKV) infection in pregnancy during the Rio de Janeiro epidemic of 2015-2016 (refs. 1,2). Neurodevelopment was assessed by Bayley Scales of Infant and Toddler Development, third edition (Bayley-III; cognitive, language and motor domains) in 146 children and through neurodevelopment questionnaires/neurological examinations in 70 remaining children. Complete eye exams (n = 137) and hearing assessments (n = 114) were also performed. Below-average neurodevelopment and/or abnormal eye or hearing assessments were noted in 31.5% of children between 7 and 32 months of age. Among children assessed by Bayley-III, 12% scored below -2 s.d. (score <70; a score of 100 ± 2 s.d. is the range) in at least one domain; and 28% scored between -1 and -2 s.d. in any domain (scores <85-70). Language function was most affected, with 35% of 146 children below average. Improved neurodevelopmental outcomes were noted in female children, term babies, children with normal eye exams and maternal infection later in pregnancy (P = 0.01). We noted resolution of microcephaly with normal neurodevelopment in two of eight children, development of secondary microcephaly in two other children and autism spectrum disorder in three previously healthy children in the second year of life.

Neurological outcome at 6 and 12 months corrected age in hospitalised late preterm infants -a prospective study

Late preterm infants (34-0/7 to 36-6/7 weeks" gestation) account for 10-20% of NICU admissions and are at increased risk for morbidity and mortality. Although they are prone to developmental delays, reports on neurological outcome during the first 2 years of life are scarce. The aim of the study was to assess neurological/neuromotor outcome in high risk late preterm infants at 6 and 12 months corrected age and the change in neurological scores over time, and to identify factors associated with the neurological outcome. The Hammersmith Infant Neurological Examination was performed in a cohort of 157 late preterm infants admitted in the NICU. The infants were examined at 6 and 12 months corrected age respectively and scored with the optimality score system including 26 items assessing cranial nerve function, posture, movements, tone and reflexes. Also parents reported neurological milestones in the follow up visit. Infants at 6 months had a global score of 59 (47-76) and optimal scores achieved in 25.4%. At 12 months they had a global score of 70 (58-78) and achieved optimal scores in 63.2%. The subscores of posture, tone and reflexes gradually increased from 6 to 12 months corrected age. Being born small for gestational age was the only factor that adversely influenced HINE score at 6 and 12 months. At 12 months 58.5% achieved independent walking. High risk late preterm infants have suboptimal HINE scores at 6 and 12 months of age, suggesting a need for closer follow up and early intervention programs.

Community-based parent-delivered early detection and intervention programme for infants at high risk of cerebral palsy in a low-resource country (Learning through Everyday Activities with Parents (LEAP-CP): protocol for a randomised controlled trial

INTRODUCTION

Cerebral palsy (CP) is the most common childhood physical disability, with 80% estimated to be in low-middle-income countries. This study aims to (1) determine the accuracy of General Movements (GMs)/Hammersmith Infant Neurological Examination (HINE) for detecting CP at 18 months corrected age (CA); (2) determine the effectiveness of a community-based parent-delivered early intervention for infants at high risk of CP in West Bengal, India (Learning through Everyday Activities with Parents for infants with CP; LEAP-CP).

METHODS

This study comprises two substudies: (1) a study of the predictive validity of the GMs and HINE for detecting CP; (2) randomised, double-blinded controlled trial of a novel intervention delivered through peer trainers (Community Disability Workers, CDW) compared with health advice (15 fortnightly visits). 142 infants at high risk of CP ('absent fidgety' GMs; 'high risk score' on HINE) aged 12-40 weeks CA will be recruited to the intervention substudy, with infants randomised based on a computer-generated sequence. Researchers will be masked to group allocation, and caregivers and CDWs naïve to intervention status. Visits will include therapeutic modules (goal-directed active motor/cognitive strategies and LEAP-CP games) and parent education. Health advice is based on the Integrated Management of Childhood Illness, WHO. Infants will be evaluated at baseline, post intervention and 18 months CA. The primary hypothesis is that infants receiving LEAP-CP will have greater scaled scores on the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (mobility domain) at 18 months compared with health advice. Secondary outcomes include infant functional motor, cognitive, visual and communication development; infant growth; maternal mental health.

ETHICS AND DISSEMINATION

This study is approved through appropriate Australian and Indian ethics committees (see in text) with families providing written informed consent. Findings from this trial will be disseminated through peer-reviewed journal publications and conference presentations.

Predictive validity of spontaneous early infant movement for later cerebral palsy: a systematic review

AIM

To systematically review the predictive validity of spontaneous early infant movements for later cerebral palsy (CP).

METHOD

Cohort studies with published data to calculate predictive validity of early spontaneous movements for later CP were searched in four electronic databases: CINAHL, Embase, MEDLINE, and PsycINFO.

RESULTS

Forty-seven studies met inclusion criteria. The Prechtl General Movements Assessment (GMA) during the fidgety period (10-20wks corrected age) had the strongest sensitivity: 97 per cent (95% confidence interval [CI] 93-99) and specificity: 89% (95% CI 83-93). The sensitivity and specificity of the Prechtl GMA during the writhing period (birth-6wks) was 93% (95% CI 86-96) and 59% (95% CI 45-71) respectively. Cramped-synchronized movements in the writhing period according to Prechtl had the best specificity (sensitivity: 70% [95% CI 54-82]; specificity: 97% [95% CI 74-100]). Hadders-Algra's method of assessing general movements had a pooled sensitivity and specificity of 89% (95% CI 66-97) and 81% (95% CI 64-91) respectively. Presence of asymmetric postures and movement quality/quantity were reported under the Hammersmith Infant Neurological Examination, Hammersmith Neonatal Neurological Examination, and Movement Assessment of Infants but had weak associations with later CP.

INTERPRETATION

Fidgety movements assessed by the Prechtl GMA have the strongest predictive validity for later CP, but cannot be considered in isolation because of the presence of false positive results.

WHAT THIS PAPER ADDS

Fidgety general movements (Prechtl) are most predictive for later cerebral palsy compared with other spontaneous movements. False positive results are high among all spontaneous movement assessments.

REACH: study protocol of a randomised trial of rehabilitation very early in congenital hemiplegia

OBJECTIVES

Congenital hemiplegia is the most common form of cerebral palsy (CP). Children with unilateral CP show signs of upper limb asymmetry by 8 months corrected age (ca) but are frequently not referred to therapy until after 12 months ca. This study compares the efficacy of infant-friendly modified constraint-induced movement therapy (Baby mCIMT) to infant friendly bimanual therapy (Baby BIM) on upper limb, cognitive and neuroplasticity outcomes in a multisite randomised comparison trial.

METHODS AND ANALYSIS

150 infants (75 in each group), aged between 3 and 6 months ca, with asymmetric brain injury and clinical signs of upper extremity asymmetry will be recruited. Children will be randomised centrally to receive equal doses of either Baby mCIMT or Baby BIM. Baby mCIMT comprises restraint of the unimpaired hand using a simple restraint (eg, glove, sock), combined with intensive parent implemented practice focusing on active use of the impaired hand in a play-based context. In contrast, Baby BIM promotes active play requiring both hands in a play-based context. Both interventions will be delivered by parents at home with monthly home visits and interim telecommunication support by study therapists. Assessments will be conducted at study entry; at 6, 12 months ca immediately postintervention (primary outcome) and 24 months ca (retention). The primary outcome will be the Mini-Assisting Hand Assessment. Secondary outcomes include the Bayley Scale for Infant and Toddler Development (cognitive and motor domains) and the Hand Assessment of Infants. A subset of children will undertake MRI scans at 24 months ca to evaluate brain lesion severity and brain (re)organisation after intervention.

ETHICS AND DISSEMINATION

Full ethical approvals for this study have been obtained from the relevant sites. The findings will be disseminated in peer-reviewed publications.

Implementation of the Hammersmith Infant Neurological Examination in a High-Risk Infant Follow-Up Program

BACKGROUND

High-risk infant follow-up programs provide early identification and referral for treatment of neurodevelopmental delays and impairments. In these programs, a standardized neurological examination is a critical component of evaluation for clinical and research purposes.

METHODS

To address primary challenges of provider educational diversity and standardized documentation, we designed an approach to training and implementation of the Hammersmith Infant Neurological Examination with precourse materials, a workshop model, and adaptation of the electronic medical record.

CONCLUSIONS

Provider completion and documentation of a neurological examination were evaluated before and after Hammersmith Infant Neurological Examination training. Standardized training and implementation of the Hammersmith Infant Neurological Examination in a large high-risk infant follow-up is feasible and effective and allows for quantitative evaluation of neurological findings and developmental trajectories.

Prediction of neuromotor outcome in infants born preterm at 11 years of age using volumetric neonatal magnetic resonance imaging and neurological examinations

AIM

To study the prognostic value of volumetric brain magnetic resonance imaging (MRI) at term equivalent age (TEA) and neurological examinations at TEA and at 2 years of corrected age for long-term neuromotor outcome in infants born very preterm.

METHOD

A total of 98 infants born very preterm were included. Structural and volumetric brain MRI and the Dubowitz neurologic examination were done at TEA. The Hammersmith Infant Neurological Examination (HINE) was performed at 2 years of corrected age. The Touwen examination was used for the assessment of minor neurological dysfunction (MND) at the age of 11 years.

RESULTS

Of all children (median birthweight 1083g [quartiles 820, 1300]; gestational age 28 5/7wks [26 4/7, 30 2/7]), 41 had simple MND, 11 had complex MND (cMND), and eight had cerebral palsy (CP). The negative and positive predictive value of structural brain MRI for cMND or CP was 88% and 50% respectively. Reduced volumes of total brain tissue, frontal lobes, basal ganglia and thalami, and cerebellum associated with cMND or CP. The results of the Dubowitz neurologic examination and the HINE correlated with the Touwen examination.

INTERPRETATION

Structural and volumetric MRI at TEA and structured neurological examinations predict long-term neuromotor outcome in infants born preterm.

Use of the Hammersmith Infant Neurological Examination in infants with cerebral palsy: a critical review of the literature

The Hammersmith Infant Neurological Examination (HINE) has been proposed as one of the early neurological examination tools for the diagnosis of cerebral palsy (CP). The aim of the present study was to critically review the existing literature and our experience with the use of the HINE in infants at risk of CP. The published papers confirm that the HINE can play an important role in the diagnosis and prognosis of infants at risk of developing CP, and provide information on aspects of neurological findings impaired in different forms of CP and brain lesions.

Home-based, early intervention with mechatronic toys for preterm infants at risk of neurodevelopmental disorders (CARETOY): a RCT protocol

BACKGROUND

Preterm infants are at risk for neurodevelopmental disorders, including motor, cognitive or behavioural problems, which may potentially be modified by early intervention. The EU CareToy Project Consortium (http://www.caretoy.eu) has developed a new modular system for intensive, individualized, home-based and family-centred early intervention, managed remotely by rehabilitation staff. A randomised controlled trial (RCT) has been designed to evaluate the efficacy of CareToy training in a first sample of low-risk preterm infants.

METHODS/DESIGN

The trial, randomised, multi-center, evaluator-blinded, parallel group controlled, is designed according to CONSORT Statement. Eligible subjects are infants born preterm without major complications, aged 3-9 months of corrected age with specific gross-motor abilities defined by Ages & Stages Questionnaire scores. Recruited infants, whose parents will sign a written informed consent for participation, will be randomized in CareToy training and control groups at baseline (T0). CareToy group will perform four weeks of personalized activities with the CareToy system, customized by the rehabilitation staff. The control group will continue standard care. Infant Motor Profile Scale is the primary outcome measure and a total sample size of 40 infants has been established. Bayley-Cognitive subscale, Alberta Infants Motor Scale and Teller Acuity Cards are secondary outcome measures. All measurements will be performed at T0 and at the end of training/control period (T1). For ethical reasons, after this first phase infants enrolled in the control group will perform the CareToy training, while the training group will continue standard care. At the end of open phase (T2) all infants will be assessed as at T1. Further assessment will be performed at 18 months corrected age (T3) to evaluate the long-term effects on neurodevelopmental outcome. Caregivers and rehabilitation staff will not be blinded whereas all the clinical assessments will be performed, videotaped and scored by blind assessors. The trial is ongoing and it is expected to be completed by April 2015.

DISCUSSION

This paper describes RCT methodology to evaluate CareToy as a new tool for early intervention in preterm infants, first contribution to test this new type of system. It presents background, hypotheses, outcome measures and trial methodology.
