Morioka Y, Nonogaki M, Kobayashi D, Nishimoto J, Obayashi S. Effects of increased physical therapy staffing in the neonatal intensive care unit on oral feeding maturation and neurodevelopment of extremely low birth weight infants. Brain Dev 2024:S0387-7604(24)00053-6. [PMID: 38556384 DOI: 10.1016/j.braindev.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 03/18/2024] [Accepted: 03/19/2024] [Indexed: 04/02/2024]
Abstract
BACKGROUND It remains a matter of debate as to what extent early intervention may facilitate long-term functional outcomes of preterm infants in the neonatal intensive care unit (NICU). We aimed to examine the effect of increasing physical therapy (PT) staff dedicated to the NICU on temporal changes (initiation, duration) of PT interventions and functional outcomes (acquisition of full oral feeding and Hammersmith Neonatal Neurological Examination). METHODS Extremely low birth weight infants, retrospectively collected from an academic medical center, were allocated to two subgroups, either a baseline period (N = 48) without NICU-dedicated PT staff (non-dedicated group) or a quality improvement period (N = 42) with additional dedicated staff (dedicated group). RESULTS Compared to those in the non-dedicated group, NICU infants in the dedicated group started PT earlier and had increased PT treatment for additional 14 min per day when achieving full oral feeding. The infants in the dedicated group significantly achieved full oral feeding earlier than the non-dedicated group. As for Hammersmith Neonatal Neurological Examination, there were significant differences in two items (total and tone) between the groups. CONCLUSIONS Additional NICU-dedicated PT staff facilitated earlier intervention and increased PT treatment in terms of daily duration. Moreover, the dedication shortened the completion of full oral feeding and improved neurological development, presumably resulting in better developmental outcome.

Associations Between Malaria in Pregnancy and Neonatal Neurological Outcomes: Malaria in Pregnancy and Neonatal Neurological Outcomes. Int J Infect Dis 2021; 112:144-151. [PMID: 34284089 DOI: 10.1016/j.ijid.2021.07.037] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 07/13/2021] [Accepted: 07/14/2021] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE To compare neurological functioning of neonates born to mothers with and without malaria in pregnancy. METHODS Pregnant women presenting at Korle Bu Teaching Hospital, Ghana were recruited into this prospective observational study. Malaria exposure was determined by clinically-documented antenatal malaria infection; parasitemia in maternal, placental, or umbilical cord blood; or placental histology. Neurological functioning was assessed using the Hammersmith Neonatal Neurological Examination within 48 hours of birth. Performance was classified as "optimal" or "suboptimal" by subdomain and overall. RESULTS Between 21st November 2018 and 10th February 2019, 211 term-born neonates, of whom 27 (13%) were exposed to malaria, were included. In the reflexes subdomain, exposed neonates tended to score lower (adjusted mean difference: -0.34, 95% CI: -0.70-0.03) with increased risk (adjusted risk ratio: 1.63, 95% CI: 1.09-2.44) of suboptimal performance compared to unexposed neonates. There were no significant between-group differences in scores or optimality classification for the remaining subdomains and overall. CONCLUSION Malaria-exposed neonates had similar neurological functioning relative to unexposed neonates, with differences confined to the reflexes subdomain, suggesting potential underlying neurological immaturity or injury. Further studies are needed to confirm these findings and determine the significance of malaria in pregnancy on long-term neurological outcomes.

Gestational Age-Specific Distribution of the Hammersmith Neonatal Neurological Examination Scores Among Low-Risk Neonates in Ghana. Early Hum Dev 2021; 152:105133. [PMID: 33249301 DOI: 10.1016/j.earlhumdev.2020.105133] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Accepted: 07/07/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To describe gestational age-specific distribution of scores for the Hammersmith Neonatal Neurological Examination (HNNE) up to 48 h after birth in a low-risk, term-born, single-center sample in Ghana. STUDY DESIGN This is a nested substudy of a larger prospective study (IMPRINT: Impact of Malaria in Pregnancy on Infant Neurodevelopment) comprising 140 low-risk, term-born neonates at Korle Bu Teaching Hospital in Accra, Ghana, between November 2018 and February 2019. The sample was stratified into three gestational age groups: early-term (37 + 0-38 + 6, weeks + days; n = 61), full-term (39 + 0-40 + 6, weeks + days; n = 52), and late/post-term (41 + 0-42 + 6, weeks + days; n = 27). Neonates were administered the 34-item HNNE by trained physicians. As per the original British scoring system, raw scores for the Ghanaian sample were plotted and scores > 10th centile were assigned a score of 1, 5th-10th centile 0.5, and < 5th centile 0. RESULTS The range of raw scores for 16/34 HNNE items varied with gestational age. Specifically, 100% (7/7), 50% (5/10), 33% (1/3), 33% (1/3), 20% (1/5), and 14% (1/7) of items within the orientation and behavior, tone, abnormal signs/patterns, movements, tone patterns, and reflexes subdomain, respectively showed a different distribution of scores above the 10th centile across the three gestational age groups. CONCLUSION Differences in gestational age-specific results within our sample in comparison to the original British sample could be, albeit unlikely, due to misclassification of gestational age, unmeasured maternal or fetal morbidity, or perhaps more likely, variation in testing or test conditions, or some combination of these. Genetic variation in neurological development is also a possibility. Further research is warranted to determine the reasons for differences. Our findings highlight the need to determine the accuracy and reliability of standardized neurologic assessments in predicting neurodevelopmental risk for infants in low- and middle-income countries.

Abstract
Background: In perinatal asphyxia, hypoxia often leads to myocardial ischaemia. Few studies have assessed the degree of myocardial dysfunction in severely asphyxiated term neonates. Aim: To assess the extent of myocardial damage in newborns with severe perinatal asphyxia. Methods: A case-control study was conducted in asphyxiated newborns with hypoxic ischaemic encephalopathy (HIE) and in controls who were term non-asphyxiated newborns. Total (T) creatinine kinase (CK), CK-MB, troponin-T and 12-lead electrocardiography (ECG) and echocardiography were performed in both groups within 24-48 h after birth. The proportions of asphyxiated neonates with myocardial dysfunction and its relationship between severity of HIE and immediate outcome was compared. Results: Five of 23 asphyxiated neonates developed stage I, 10 stage II and eight stage III HIE. Serum levels of CK-T and CK-MB were raised in all 23 cases and troponin-T was raised in 13 (56.5%) HIE cases. ECG was abnormal in all cases and echocardiography in three (13%). Left ventricular ejection fraction (LVEF) and right ventricular ejection fraction (RVEF) were significantly decreased in all asphyxiated neonates. Eight (35%) patients died. Enzyme levels were higher and ECG and echocardiography abnormalities were common in infants with more severe HIE (p <0.05). Mean serum levels of CK-T and MB (p <0.001) and troponin-T (p =0.002) were higher in non-survivors. Mean LVEF and RVEF values were higher in survivors (p <0.001). All the controls had normal enzyme levels and echocardiography. ECG was abnormal in one control. Conclusion: Cardiac enzymes, ECG and echocardiography changes were associated with increasing severity of HIE and mortality.

Abstract
AIMS We conducted a longitudinal cohort study to analyze the relationship between outcome of gross motor development in preterm infants and factors that might affect their development. METHODS Preterm infants with a birth weight of <1500 g were recruited. We measured spontaneous antigravity limbs movements by 3D motion capture system at 3 months corrected age. Gross motor developmental outcomes at 6 and 12 months corrected age were evaluated using the Alberta Infant Motor Scale (AIMS). Statistical analysis was carried out by canonical correlation analysis. RESULTS Eighteen preterm infants were included. In the 6 months corrected age analysis, spontaneous movement had a major effect on Prone and Sitting at 6 months corrected age of AIMS. In the 12 months corrected age analysis, spontaneous movement had a major effect on Sitting and Standing at 12 months corrected age of AIMS. CONCLUSIONS In preterm infants, better antigravity spontaneous movements at 3 months corrected age were significantly correlated with better gross motor development at 6 or 12 months corrected age.

Abstract
The aim of this paper was to systematically review the literature on the significance of specific neurological signs in infancy, in particular in infants at risk for developmental problems such as cerebral palsy (CP). A literature search was performed using the databases PubMed, Embase, Web of Science, and AMED. Papers on infantile reactions ('primitive reflexes') and postural reactions were included if data were available allowing for calculation of sensitivity, specificity, or positive and negative predictive value for CP or atypical developmental outcome. Our search identified 23 articles on 20 different neurological signs. Properties of six neurological signs were reported in at least three different papers. The data indicated that, in early infancy, an absent Moro or plantar grasp response may be predictive for adverse developmental outcome. After early infancy, persistence of the Moro response and asymmetric tonic neck reflex was clinically significant. Prediction of a delayed emergence of the parachute reaction increases with age. Abnormal performances on the pull-to-sit manoeuvre and vertical suspension test have predictive significance throughout infancy. The neurological signs reviewed have some predictive value in infants at risk. For most of the signs, criteria for abnormality and significance are age-dependent.

Abstract
The neurological exam can be a challenging part of a newborn's full evaluation. At the same time, the neonatal neurological exam is a useful tool in identifying babies needing closer evaluation for potential problems. The Dubowitz assessment is a standardised approach to the neonatal neurological exam designed for use by paediatricians in routine practice. Evidence has validated this technique and delineated its utility as a screening exam in various populations. This paper reviews clinical application of the Dubowitz assessment of the newborn.

Abstract
This article presents the elements of the Observation and Assessment section of the Infant Care Path for Physical Therapy in the Neonatal Intensive Care Unit (NICU). The types of physical therapy assessments presented in this path are evidence-based and the suggested timing of these assessments is primarily based on practice knowledge from expert therapists, with supporting evidence cited. Assessment in the NICU begins with a thorough review of the health care record. Assessment proceeds by using the least invasive methods of gathering the behavioral, developmental, physiologic, and musculoskeletal information needed to implement a physical therapy plan of care. As the neonate matures and can better tolerate handling, assessment methods include lengthier standardized tests with the psychometric properties needed for informing diagnosis and intervention planning. Standardized tests and measures for screening, diagnosis, and developmental assessment are appraised and special considerations for assessment of neonates in the NICU are discussed.

Abstract
AIM The aim of this study was to systematically review the clinimetric properties of longitudinal neonatal neurobehavioural and neuromotor assessments for preterm infants. METHOD Twenty-seven assessment measures were identified. The following eight measures met the study inclusion criteria: Assessment of Preterm Infants' Behaviour (APIB), Neonatal Intensive Care Unit Network Neurobehavioural Scale (NNNS), Test of Infant Motor Performance (TIMP), Prechtl's Assessment of General Movements (GMs), Neurobehavioural Assessment of the Preterm Infant (NAPI), Dubowitz Neurological Assessment of the Preterm and Full-term Infant (Dubowitz), Neuromotor Behavioural Assessment (NMBA), and the Brazelton Neonatal Behavioural Assessment Scale (NBAS). The primary purposes included prediction (TIMP, GMs, Dubowitz), discrimination (all assessments), and evaluation of change (TIMP, NAPI). Measures of assessment were included in the study if they were (1) primarily neurobehavioural or neuromotor assessments that were suitable for use with preterm infants (<37 weeks gestation) up to 4 months corrected age and were discriminative, predictive, or evaluative; (2) standardized procedures designed for serial/longitudinal use; or (3) criterion or norm referenced. However, all assessment tools that were not published in English in a peer-reviewed journal or were primarily neurological assessments, one-time evaluations, screening tools, or not commercially available were not used. RESULTS All of the measures included in the review demonstrated adequate content and construct validity. Concurrent validity was reported for APIB, NNNS, Dubowitz, and GMs. Predictive validity was high for GMs with studies reporting up to 100% senstivity for predicting cerebral palsy at the age of 12 to 24 months. Interrater reliability was strong for the TIMP (intraclass correlation=0.95), GMs (K=0.8), and moderate for the NAPI (r=0.67-0.97). Clinical utility was variable for ease of scoring, interpretability, cost, and access. INTERPRETATION In the absence of a criterion standard for neonatal neuromotor assessments, the NNNS and APIB have strong psychometric qualities with better utility for research. Similarly, the GMs, TIMP, and NAPI have strong psychometric qualities but better utility for clinical settings. The GMs has best prediction of future outcome and the TIMP has best evaluative validity.

Abstract
OBJETIVO: Comparar a avaliação neurológica de recém-nascidos pré-termo em idade de termo com a de recém-nascidos a termo e verificar a presença de associação entre alterações na avaliação neurológica e características e intercorrências clínicas nos prematuros. MÉTODO: Estudo transversal de 60 nascidos a termo e 30 prematuros do Hospital Estadual Mário Covas, em Santo André (SP), avaliados pelo método Dubowitz. Os pontos de corte da pontuação total foram 30,5 e 26 para comparar recém-nascidos pré-termo e a termo, respectivamente. Os prematuros foram avaliados com idade correspondente ao termo, na 37ª semana, e os do grupo controle, 48 horas após o nascimento. Todos os neonatos foram avaliados pela mesma examinadora, entre as mamadas, nos estágios 4 e 5 de sono e vigília. Para análise estatística, utilizaram-se testes de associação. RESULTADOS: 90% dos nascidos pré-termo não atingiram a pontuação esperada para a idade de termo (p<0,0001), com alterações mais evidentes nas dimensões: tônus, tipo de tônus e movimentos. Dentre os prematuros, 57% não atingiram pontuação total igual ou superior a 26. A sepse neonatal foi a única intercorrência associada de maneira significante, com pontuações abaixo da normalidade em recém-nascidos pré-termo (p=0,009). CONCLUSÃO: Os recém-nascidos pré-termo avaliados com 37 semanas de idade corrigida, quando comparados aos nascidos a termo, apresentaram menor pontuação no exame neurológico e apenas a sepse se associou a alterações neurológicas.

Abstract
Oscilações na pressão arterial (PA) sistêmica são diretamente proporcionais às oscilações do fluxo sangüíneo cerebral nos prematuros, mas são escassos os estudos acerca do efeito dos procedimentos fisioterapêuticos sobre a PA. Este estudo investigou a repercussão desses procedimentos e da aspiração endotraqueal na pressão arterial em recém-nascidos pré-termo (RNPT) na primeira semana de vida. Foram estudados 42 RNPT com peso de nascimento menor que 1.500 gramas em ventilação mecânica. A PA foi mensurada em três momentos: antes da fisioterapia (A), imediatamente após os procedimentos fisioterapêuticos (B) e imediatamente após a aspiração endotraqueal (C). Os dados coletados foram analisados estatisticamente, com nível de signficância fixado em p<0,05. Os 42 RNPT tinham idade gestacional média de 29,58±2,16 semanas e peso médio ao nascer 1012,68±274,16 g, com predominância do sexo feminino (57,1%) e da doença das membranas hialinas (90,4%). As médias das variáveis estudadas, respectivamente pressão arterial sistólica, diastólica e (média), em mmHg, foram: momento A, 71,32 x 40,56 (53,04); momento B, 69,93 x 39,41 (51,98); e momento C, 74,29 x 43,75 (54,82). A PA dos recém-nascidos permaneceu dentro dos valores fisiológicos após os procedimentos fisioterapêuticos e de aspiração, portanto as intervenções fisioterapêuticas realizadas não podem ser consideradas prejudiciais para os RNPT; a aspiração endotraqueal teve maior influência nas oscilações da PA.

Abstract
OBJECTIVE To evaluate the possible additional benefit in terms of prognostic accuracy of an integrated application of a traditional scorable method of neurologic examination and the Prechtl's method of qualitative assessment of general movements (GMs) in a large population of 903 consecutive preterm infants. STUDY DESIGN Infants were enrolled from the Intensive Care Unit of the University of Catania. Inclusion criteria were a gestational age below 37 weeks and the absence of genetic disorders. All infants underwent serial ultrasound and at 3 months performed both the GMs assessment and the Hammersmith Infant Neurologic Examination (HINE). Outcome was assessed at 2 years by the Touwen neurologic examination and the Clinical Adaptive Test/Clinical, Linguistic and Auditory Milestone Scale. RESULTS The integration of the two methods was shown to be more effective than the single assessments in predicting neurologic outcome. The additional benefit of combining the two approaches was particularly clear for the discrimination between unilateral and bilateral cerebral palsy. CONCLUSIONS The integrated use of a scorable neurological examination and Prechtl's assessment of GMs can improve early prediction of neurodevelopmental outcome in preterm infants and should complement other clinical and instrumental exams in follow-up programs.

Abstract
OBJECTIVE The general movement assessment (GMA) method is used to predict cerebral palsy (CP) in infants with high risk of developing neurological dysfunctions. Most of the work on GMA has been performed from the same group of researchers. The aim of this study was to demonstrate to what extent GMA predicted CP in our hands. METHOD A prospective study was performed using the Prechtl classification system for GMA in the fidgety period to predict later cerebral palsy. The study population consisted of 74 term and preterm infants at low and high risk of developing neurological dysfunction. The absence or presence of CP was reported at 23 months median-corrected age by the child's physician and the parents. RESULTS The GMA identified all 10 infants that later were classified as having CP. GMA also identified all the infants that did not develop CP except for one infant with abnormal GMA and no CP. Three infants had uncertain CP status at follow-up. The sensitivity of GMA with regard to later CP was 100% with 95% CI (0.73, 1.00) and the specificity was 98% with 95% CI (0.91, 0.99) when the three uncertain cases were excluded. CONCLUSION Our study indicates that the GMA used in a clinical setting strongly predicts the development of CP. The work supports the results of previous studies and contributes to the validation of GMA. The qualitative nature of this method may be a problem for inexperienced observers. Larger clinical studies are needed.

Abstract
PURPOSE The study was designed to compare active motor items at term age of infants born very preterm, very low birth weight (VPT-VLBW) and without impairments with infants born full-term (FT) and healthy and to evaluate a method of assessment using video recordings and computer software. METHOD Video recordings of head lag and head righting on pull to sit, head control in sitting, and hip flexion in prone were obtained at term age for 29 infants born VPT-VLBW and 22 infants born FT. Motor items were analyzed using digitizing computer software. RESULTS Infants born VPT-VLBW had less head lag on pull to sit than infants born FT, p = 0.005. No other differences were found for the remaining motor items. The method of assessment demonstrated high intrarater reliability (intraclass coefficient correlation (3,1) = 0.77-0.997). CONCLUSIONS Infants born VPT-VLBW who are at "low risk" performed at term age similarly to healthy infants born FT on four active motor items. The reliability of the measurement method supports the method's further development.

Abstract
The purpose of this study was twofold: (1) to explore potential changes in the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) from 40 to 44 weeks postconceptional age (PCA) and (2) to determine the relationship between the BNBAS scores and feeding behaviors in preterm infants at 40 and 44 weeks PCA. The BNBAS and sucking behavior measurements were completed on 104 preterm infants at 40 and 44 weeks PCA. The Orientation (p = .001), Motor (p = .001), Range of State (p = .001), Autonomic Regulation (p = .01), and Reflexes (p = .00) clusters were significantly more mature at 44 weeks PCA than at 40 weeks. Infants that were extremely early born (n = 24) had a significantly larger change in BNBAS scores over time as compared to the more mature preterm infants (n = 77), largely catching up with their more mature preterm counterparts. At 40 and 44 weeks PCA, the BNBAS cluster scores for orientation (p = .02), motor (p = .048), range of state (p = .048), and regulation of state (p < .001) were significantly related to the average maximum pressure, adjusted for gestational age and weeks PCA. Significant neurobehavioral maturation takes place between 40 and 44 weeks PCA in preterm infants, with the greatest changes occurring in the most preterm infants. These findings highlight the relationship between neurobehavioral maturation and feeding behaviors.

Abstract
This study examined in a regional cohort of 66 term age very low birth weight infants, the relationship between qualitative magnetic resonance imaging (MRI) measures of cerebral white and gray matter abnormalities and infant neurobehavioral functioning assessed by structured neurological examination. The diagnostic utility of the Dubowitz neonatal neurological examination in identifying children with severe cerebral abnormalities was also evaluated. Examination results revealed the presence of high rates of neurological abnormality, with 60% of infants scoring in the suboptimal range relative to infants born full term. Linear associations were found between the severity of structural cerebral abnormality on MRI and the quality of clinically rated infant neurobehavioral functioning, with increasing abnormalities being significantly associated with poorer neurological functioning. In particular, white matter abnormalities were significantly associated with lower mean tone and tone pattern scores and a tendency toward lower mean reflex scores. Gray matter abnormalities were significantly associated with lower tone and tone pattern scores and a tendency toward lower spontaneous movements and orientation/behavior scores. Finally, the Dubowitz Neonatal Neurological Examination was found to have relatively good sensitivity (88%; negative predictive value, 92%) but poor specificity (46%; positive predictive value, 34%) for identifying children with significant MRI abnormalities. Implications of these findings for the neurological evaluation of the very low birth weight infant are discussed.

Abstract
OBJECTIVE To compare the development of motor function in children born preterm with those born at term, at 8 and 12 months of age. To investigate the relation of motor function quality at the age of 8 months with motor ability at 12 months. METHOD Thirty-two children participated in this study: 16 were born preterm (risk group) and 16 were born at term (control group). The spontaneous movements of the children were assessed at 8 months and their mobility skills and independence were assessed at 12 months (corrected ages for the preterm group), using standardized developmental tests (AIMS and PEDI, respectively). Data were analysed using independent t-tests (between-group comparison) and Pearson correlation coefficients (within-group comparison). RESULTS There was no significant difference in motor function, between those born preterm with those born at term, either at 8 or at 12 months of age. In the control group, there was significant association (r=0.67; p=0.004) between movement at 8 months and mobility skills at 12 months. In the risk group, there was significant relationship between skills and independence in mobility, at 12 months corrected age (r=0.80; p=0.0001). CONCLUSION Preterm born children, without other disorders and with age correction, might show a similar motor development as those born at term. The path for the acquisition of motor abilities in preterm born children appears to differ among those infants.

Abstract
A mortalidade perinatal e a incidência de sequelas neurológicas em prematuros têm diminuído, dado os avanços da perinatologia. A avaliação acurada da idade gestacional (IG) é um componente essencial para o manejo dessas crianças. Procuramos avaliar o desempenho do teste neurológico em comparação com as escalas obstétrica (DUM) e neonatais (de Dubowitz e de Capurro). e comparar as idades gestacionais obtidas após a aplicação das diferentes escalas. Foram examinados 35 recém-nascidos, sendo excluídos aqueles com qualquer comorbidade. Após a aplicação das escalas e determinação das idades gestacionais, realizou-se o exame neurológico e anamnese com os pais. Os resultados obtidos demonstraram que o método neurológico de André-Thomas avalia os padrões do exame neurológico clássico do recém-nascido e, embora não seja um método amplamente utilizado na prática médica, mostrou ser fidedigno para a avaliação da IG.

Abstract
The aim of the study was to find if neurological function during the first year of life could predict neuromotor behaviour at 7 years of age in children born preterm with a high risk. A follow-up study of neuromotor behaviour in 52 children at a mean age of 3, 6, 12 months (corrected age) and 7 years was performed. All children were born with a gestational age less than 32 weeks and/or a birthweight under 1500 g and the infants were categorised according to their medical history in the three highest categories of the 'Neonatal Medical Index' (NMI, from category I to V, from few to serious complications). In addition, neonatal cerebral ultrasound abnormalities were used to divide the infants further into the different NMI categories. At 3 and 6 months, the relationship between active and passive muscle power was measured in shoulders, trunk and legs and (a)symmetry between right and left was noted. The results at 3 and 6 months were ranged from 1 for optimal to 5 for poor muscle power regulation. At 12 months of age, a neurological examination was done with special emphasis on the assessment of postural control, spontaneous motility, hand function and elicited infantile reactions with special attention to (a)symmetry. Outcome at 12 months was expressed as percentage of the optimal score on each subcategory. At 7 years, the motor behaviour study based on Touwen's examination for minor neurological dysfunction was performed. This investigation focuses on different functions, such as hand function, quality of walking, posture, passive muscle tone, coordination and diadochokinesis. The outcome was expressed as percentage of the optimal score on the combined subcategories. The best prediction of neuromotor behaviour at 7 years was assessed with stepwise linear multiple regression, using as potential predictors perinatal factors and outcome of motor behaviour at the corrected age of 3, 6 and 12 months. At 7 years none of the children scored 100% on the combined subcategories, 15 children (29%) scored between 75% and 99%, whereas 15 children scored less than 50%. Neuromotor behaviour at 7 years could be predicted by the NMI categorisation and gender with a sensitivity of 92% (specificity 47%; positive and negative predictive value 81% and 70%). No direct relation was found between neuromotor behaviour and cerebral ultrasound classification only, days on the ventilator and/or continuous positive airway pressure, birthweight, gestational age and dysmaturity. The best predictor of neuromotor behaviour at 7 years was the combination of outcome of muscle power in shoulders and legs at 3 months and postural control at 12 months, taking into account the gender of the child (sensitivity 95%; specificity 40%; positive predictive value 80%; negative predictive value 75%).

Abstract
The aim of the study was to design and test a neurological examination for newborns that could be performed reliably by paramedical staff in resource-poor settings. The examination was adapted from a method established by Dubowitz et al., the latest version of which includes an optimality score. The final items in the test were chosen because they were culturally acceptable, could be elicited according to strict but easily comprehensible instructions and because the expected responses could be scored by the descriptions given or by diagrams in the proforma. The shortened examination was easily taught to paramedical staff who achieved a high degree of inter-observer reliability. This shortened version of the examination was piloted by comparing newborns from a Karen refugee camp on the western border of Thailand and from a large maternity hospital in Bangkok with a standardized cohort of newborns in London. The modified shortened version of the test was sufficiently sensitive to identify a number of differences between the cohorts, notably the poor vision performance and markedly reduced tone of the Karen newborns. In conclusion, the test can be used very reliably by paramedical staff and is a useful, simple and portable tool for the neurological assessment of newborn babies where resources are limited.

Abstract
We describe the application of a revised version of the Dubowitz neurologic examination of the newborn in 224 low-risk, term newborn infants. The method has been updated by eliminating less useful items and including new items evaluating general movements and patterns of distribution of tone. An optimality score is included to make the evaluation more quantitative and for comparison with sequential examinations with neurophysiologic and imaging findings. The score is based on the distribution of the scores for each item in the population of low-risk term infants. We defined not only the most common pattern for each item but also the variability of the findings by using 10th and 5th centiles. Because most of the items assessing tone and the Moro reflex varied with gestational age between 37 and 42 weeks, the changes were incorporated in the scoring system. The total optimality score was the sum of the optimality scores of individual items. Although the association of 4 or more deviant scores was found in less than 10% of our infants, deviant results on 1 or 2 single items could be observed in a third of this normal population, suggesting that isolated deviant signs have little diagnostic value. In contrast, an abnormal distribution of tone patterns, which we have commonly observed in infants with brain lesions, was not found in this cohort.

Abstract
The qualitative assessment of general movements (GMs) has been shown to be a better predictor of neurological outcome than the traditional neurological examination in brain-damaged preterm infants. The aim of this study was to compare the results of the two techniques in term infants. Off-line assessment of GMs from videorecordings and neurological examinations were carried out, from birth till about 6 months of postterm age, in a group of 58 term infants, the majority of which were affected by mild to severe hypoxic-ischaemic encephalopathy. The agreement between the two techniques and their predictive power, with respect to the neurological outcome at 2 years, were evaluated for four age groups. The range of agreement between neurological and GM findings was between 78 and 83%. At all ages the results of GM observation correlated highly with the neurological outcome; their sensitivity and specificity with respect to outcome were consistently slightly superior to those of neurological examination. In infants normalize after an initial period of transient abnormalities, GMs normalize earlier than the neurological results.

Abstract
OBJECTIVE The Prechtl method of qualitative assessment of general movements (GMs) has been shown to be a good predictor of neurologic outcome in fetuses, preterm infants, and term infants. The aim of this study was to compare the results of this new technique with those of traditional neurologic examination and of cranial ultrasonography in preterm infants. METHODS Serial videotape recordings (with off-line assessment of GMs), ultrasound examination of the brain, and neurologic examinations were performed from birth until about 6 months of corrected age, on a group of 66 preterm infants whose gestational age ranged from 26 to 36 weeks (mean 30.7 weeks). The agreement between the two techniques and their predictive power, with respect to the neurologic outcome at 2 years of corrected age, were evaluated for five different age groups from preterm age to 65 weeks of postmenstrual age. RESULTS Overall agreement of the neurologic and GM findings was 80.3% and strongly age related (lower during the preterm and term periods and higher thereafter). At all ages the results of GM observation correlated highly with neurologic outcome; they showed higher sensitivity and specificity than the neurologic examination. This held true in particular before term age, when poor neurologic responses might be related to transient complications, and at term age, mainly because of infants with normal neurologic examination results but unfavorable outcome. During the preterm period the ultrasound results showed a better specificity and a lower sensitivity to outcome than GM findings. CONCLUSIONS The results of this study indicate that quality assessment of GMs should be added to traditional neurologic assessment, neuroimaging, and other tests of preterm infants for diagnostic and prognostic purposes.

Abstract
Preterm birth is associated with an increased risk for neurological handicaps. The purpose of the present study has been: to investigate the influence of perinatal risk factors on early neuromotor development during the neonatal period; to specify the neuromotor parameters particularly sensitive to perinatal complications; and to analyse whether the infant's age at test influences the results. Beside examination of passive/active muscle tone and automatic movements (22 parameters) was performed at 36 (101 infants) and 40 (153 infants) gestational weeks. Low birthweight and long treatment on a ventilator had a negative influence on the neuromotor behaviour at 36 weeks' gestation and white matter disturbances strongly affected the neuromotor parameters at 40 weeks. The development of rooting, sucking, swallowing and arm recoil after long-lasting ventilator treatment was affected by several neonatal risk factors. The development of passive muscle tone and several parameters measuring active muscle tone demonstrated individual consistency between tests, i.e. an infant's rank at 36 weeks' gestation was unchanged 4 weeks later, and some other parameters were not as consistent. The present study shows that several perinatal risk factors influence neuromotor behaviour already during the neonatal period. In addition, the present study provides data on the neuromotor behaviour during the neonatal period that will be related to later neurodevelopmental examinations in order to evaluate the prognostic value of testing neuromotor development.
