Neuromotor development of preterm and full-term infants
Early Human Development, 1988
The Neuromotor Behavioral Inventory (NBI), a 16-category measure of muscle tone, developmental motor abilities, quality of movement, neurological reflexes and reactions, and neuromotor outcome was used with 38 infants divided into three groups: healthy preterm (HPT), sick preterm (SPT), and healthy full-term (HIT) infants. Infants were tested at five time points: 40 weeks postconception (newborn) and 3,6,9 and 12 months of age post-term. The intent of the study was twofold: to determine whether there are developmental differences among the groups of infants and whether the differences persist during the first year of life. Results indicate that HPT and HPT infants score higher than SPT infants in the neuromotor categories of: muscle tone, upper extremity development, head control, and neuromotor outcome rating. HPT infants scored higher than both preterm groups in: trunk rotation, reaction to movement, visual and auditory attention, and fixing. Differences persisted among the gorups during the first year of life in the following: the developmental motor ability of trunk rotation, fixing, adaptability, and the neuromotor outcome rating. It appears that neonatal health status is a contributing factor to infant neuromotor development, particularly in the quality of movement reactions. preterm infants; neuromotor development; perinatal illness

Background: Qualitative aspects of the motor repertoire, at 11-16 weeks post-term are predictive for minor neurological dysfunction (MND) at 7 to 11 years of age. Predictive value of quantitative aspects is unknown so far. Aim: To investigate whether quantitative aspects of the motor repertoire between 6 and 24 weeks post-term also have predictive value for neurological outcome at 7 to 11 years of age. Study design: Prospective cohort study. Subjects: Preterm infants from whom several quantitative aspects of the motor repertoire were assessed between 6 and 24 weeks post-term. Outcome measures: Neurological outcome at 7-11 years of age was assessed according to Touwens' neurological examination. Children were classified as neurologically normal, or as having complex MND or cerebral palsy (CP). Results: Eighty-two children were included. At 7 to 11 years of age 15 children (18%) had developed CP, 49 (60%) were neurologically normal, and 18 (22%) had MND. Multiple logistic regression analysis showed that, when the qualitative aspects of the motor repertoire known to predict neurological outcome were taken into account, only the asymmetric tonic neck (ATN) posture provided additional predictive value. In case of normal fidgety movements (FMs) accompanied by an abnormal concurrent motor repertoire, the presence of an obligatory ATN increased the risk for developing complex MND to 75%; absence of an obligatory ATN reduced the risk to 15% (p b 0.05). ava i l a b l e a t w w w. s c i e n c e d i r e c t . c o m w w w. e l s ev i e r. c o m / l o c a t e / e a r l h u m d ev Early Human Development (2009) 85, 25-36
Comparison of Motor Development in Preterm, and Term Children Aged 3 to 7 Years
Modern Care Journal, 2020
Background: Human development is influenced by genetic, environmental, and social factors whose foundation is formed from infancy and childhood. Preterm birth and low birth weight are important issues that can affect the development and threaten the public health. Objectives: The aim of this study was to evaluate and compare motor development manipulation, balance, aiming, and receiving in low, very low birth weight, and normal children aged 3 to7 years. Methods: In this comparative study, 63 children were selected from among the preterm infants admitted to NICU ward. They were divided into three groups of (1) low birth weight children (mean 2066 ± 354 g) (n = 30), (2) very low birth weight children (mean 1325 ± 117 g) (n = 13), and (3) preterm twin children (mean 1781 ± 385 g) (n = 20).Also, 15 term children with an average weight (3345 ± 365 g) were selected. To evaluate the motor development of children, the Movement Assessment Battery for Children (Second Edition) (MABC-2) test ...

Background: Proper motor development can be influenced by a range of risk factors. The resulting motor performance can be assessed through quantitative and qualitative analysis of posture and movement patterns. Methods: This study was designed as the cohort follow-up of the motor assessment and aimed to demonstrate, in a mathematical way, the impact of particular risk factors on elements of motor performance in the 3 rd month and the final motor performance in the 9 th month of life. Four hundred nineteen children were assessed (236 male and 183 female), including 129 born preterm. Each child aged 3 month underwent a physiotherapeutic assessment of the quantitative and qualitative development, in the prone and supine positions. The neurologist examined each child aged 9 month, referring to the Denver Development Screening Test II and assessing reflexes, muscle tone and symmetry. The following risk factors were analyzed after the neurological consultation: condition at birth (5 th min Apgar score), week of gestation at birth, intraventricular hemorrhage, respiratory distress syndrome, and the incidence of intrauterine hypotrophy and hyperbilirubinemia determined based on medical records. Results: A combination of several risk factors affected motor development stronger than any one of them solely, with Apgar score, hyperbilirubinemia, and intraventricular hemorrhage exhibiting the most significant impact. Conclusions: Premature birth on its own did not cause a substantial delay in motor development. Nonetheless, its co-occurrence with other risk factors, namely intraventricular hemorrhage, respiratory distress syndrome, and hyperbilirubinemia, notably worsened motor development prognosis. Moreover, improper position of the vertebral column, scapulae, shoulders, and pelvis in the third month of life may predict disturbances in further motor development.
Neuromotor Development of Children Aged 6 and 7 Years Born before the 30th Week Gestation
BioMed Research International, 2018
The aim of this study was to evaluate and compare the level of neuromotor function and somatic development in 6-and 7-year-old children born before the 30th week gestation with that in full-term children at the same age, as well as the correlation between prematurity and motor development. Material and Methods. The study group consisted of prematurely born 40 children. Their mean gestational age at birth was 27.8±1.6 weeks (range 24-30 weeks). The control group consisted of 40 healthy children born with normal birth weight (>2500 g). The neuromotor function was assessed using Touwen neurological examination criteria. During the examination, the attention was focused on the hand preference, laterality, synkinesis, and asymmetry. In addition, children's weight, height, and BMI index were measured. Results. Premature children showed much worse results than full-term ones in hand function (< 0, 001). They obtained the best results in paper tearing while crossing the body midline turned out to be the most difficult. Considering the quality of walking, the biggest difficulty for the premature children was to walk backwards along the straight line while during normal walking they showed the best results. The results for the muscle tone subcategory in the study group were also significantly worse than those in control group (< 0, 001), as well as the total outcome for the movement coordination and diadochokinesis subcategories (< 0, 001). Conclusion. The nondisabled, prematurely born children have significantly lower average outcomes regarding hand function, quality of walking, muscle tone, coordination, and diadochokinesis at age of six to seven, compared to the full-term peers.

Objectives: To compare the motor development of preterm infants whose gestational age had been corrected to 38-40 weeks with full term newborns using the Test of Infant Motor Performance (TIMP). Methods: The cross-sectional study compared preterm infants (PT group), with a gestational age at birth of 28-33 weeks, at an equivalent age to full term newborns (FT group), who were assessed up to 48 hours after birth. The assessments were performed between December 2008 and April 2009 in a hospital nationally recognized for premature infant care in the city of Recife, PE, Brazil. The sample consisted of 92 infants, 46 in each group. The test was administered at age 38-40 weeks (or equivalent age in the PT group). Results: In the 46 preterm infants studied, 26.1% were classified as atypical, while in the FT group 100% were classified as typical (p<0.001). Moreover, there was a significant difference in average raw TIMP score between the two groups, with the PT group being lower (p<0.001). Conclusions: According to TIMP performance, prematurity seems to be associated with impaired motor development.

Introduction: The Alberta Infant Motor Scale (Alberta Scale in the text) is used globally to evaluate the motor development, in both preterm and term children under the18 months of birth, in Colombia the tool is used, but there is few information about the results it gives when applied in our environment. Objectives: characterize a retrospective cohort of children under 1 year according to the Alberta Scale to generate information about the results of the application of this one in Colombian population attended in a fourth level hospital. Methods: Descriptive, retrospective, cross-sectional study, where the medical histories of 411 children with corrected age between 0 and 12 months of birth and background of gestational age under 40 weeks were evaluated. To all the children were applied the Alberta Scale between 2010 and 2016 and the scores according to this were statistically analyzed in a descriptive form. Results: Most of the patients were classified by the scale as "normal development" as it was expected from their background, the children of our sample present lower scores than the original Canadian sample at all the ages. Conclusion: The scale showed to be useful at the screening of the normal child, however, the patients presented lower scores when evaluated by the scale than in the original study, evidence is generated about the need to validate the scale in Colombia and to generate reference curves for this.

Introduction: Prematurity and low birth weight are conditions that may compromise the normal development of a child at different stages of development. Considering that these conditions may cause delay in the acquisition of motor skills, it is important to evaluate, detect and prevent possible changes in motor development. Objective: To investigate the influence of prematurity and low birth weight on the motor development of children of three years old relating chronological age to general motor age. Methods: This is an analysis of five cases of preterm children 32.1 (± 1.82) weeks and underweight 1704 (± 384.41) grams, mean chronological age of 43.2 (± 2.59) months, evaluated through the Motor Development Scale (MDS) in the Laboratory of Electromyography and Kinematics (LAELCIN) of the Federal University of Triângulo Mineiro (UFTM), considering general motor age (GMA) and chronological age (CA) as variables. Case: The five preterm and low birth weight children presented a differenc...
