Objective: To determine chronological and corrected ages at acquisition of motor abilities up to independent walking in very low birth weight preterms and to determine up to what point it is necessary to use corrected age. Methods:This was a longitudinal study of preterms with birth weight < 1,500 g and gestational age ≤ 34 weeks, free from neurosensory sequelae, selected at the high-risk infants follow-up clinic at the Hospital das Clínicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (UNESP) in Botucatu, Brazil, between 1998 to 2003, and assessed every 2 months until acquisition of independent walking.Results: Nine percent of the 155 preterms recruited were excluded from the study, leaving a total of 143 patients. The mean gestational age was 30±2 weeks, birth weight was 1,130±222 g, 59% were female and 44% were small for gestational age. Preterms achieved head control in their second month, could sit independent at 7 months and walked at 12.8 months' corrected age, corresponding to the 4th, 9th and 15th months of chronological age. There were significant differences between chronological age and corrected age for all motor abilities. Preterms who were small for their gestational age acquired motor abilities later, but still within expected limits. Conclusions:Very low birth weight preterms, free from neurosensory disorders, acquired their motor abilities within the ranges expected for their corrected ages. Corrected age should be used until independent walking is achieved. J Pediatr (Rio J). 2010;86(2):143-148:Very low birth weight newborn, motor activity, development, gestational age. ResumoObjetivo: Determinar as idades cronológica e corrigida de aquisição das habilidades motoras até a marcha independente em prematuros de muito baixo peso e avaliar até quando é necessário o uso da idade corrigida.Métodos: Estudo longitudinal de prematuros < 1.500 g e com idade gestacional ≤ 34 semanas, sem alterações neurossensoriais, selecionados no ambulatório de seguimento de recém-nascidos de alto risco do Hospital das Clinicas da Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (UNESP), Botucatu (SP), no período de 1998 a 2003, e avaliados a cada 2 meses até a aquisição da marcha independente.Resultados: Dos 155 prematuros incluídos, 9% foram excluídos, sendo estudados 143 pacientes. A idade gestacional média foi 30±2 semanas, o peso ao nascimento, 1.130±222 g, 59% foram do sexo feminino e 44%, pequenos para idade gestacional. Os prematuros controlaram a cabeça no 2º mês, sentaram sem apoio aos 7 meses e andaram com 12,8 meses de idade corrigida, correspondendo respectivamente ao 4 o , ao 9 o e ao 15 o mês de idade cronológica. Para todas as habilidades motoras houve diferença significativa entre idade cronológica e corrigida. Prematuros pequenos para idade gestacional adquiriram suas habilidades mais tardiamente, porém dentro do limite esperado. Conclusões:Prematuros de muito baixo peso, sem alterações neurossensoriais, adquirem as habilidades motoras dentro do prazo prev...

“…Early diagnosis of risks to the development can increase the chances of recovery of children with delay, enable access and adequate care, providing better quality of life. There is evidence that the earlier the delay diagnosis and intervention, the lower the impact of these problems on the child's development and future life 27 . The development in early childhood is positively associated to joint activities between caregivers and children, such as reading, playing, listening to stories, counting, singing or to take a walk outside, which illustrate the importance of a care environment for the child's development 40 .…”

“…When children are unable to move freely, damage may occur in the learning and in the use of feedback and feedforward, essential for motor skills acquisition. Keeping infants most of the time on one's lap, in cribs, stroller or high chair may delay their motor development 27 . Previous studies confirm the influence of maternal practices in the child's development, highlighting that the children-focused care may improve their performance, if sensory-motor experiences are provided, and may limit their acquisitions as a result of constraints linked to tasks and contexts 41 .…”

“…Initially, AIMS was developed and validated for Canadian children 15 , but it has been used in researches and clinical practices worldwide [16][17][18][19][20][21] . It was also validated in countries such as Japan 22 and China 23 , and in Brazil it was standardized and validated for the Brazilian population [24][25][26] , where it is frequently used in motor development studies of Brazilian children [27][28][29][30][31][32] . Early interventions are recognized by their capacity of reducing the risk of motor developmental delay 33-35. Routines based on early intervention for children with or at risk of delayed development encourages collaboration among professionals and families to foster functional results and achieve the goals selected by the family 36 .…”

| Early intervention based on parental activities promotes cognitive, physical, social, and emotional development, which are determinants for the child's health.However, studies about early intervention with parental education are scarce. The objective of this study was to analyze the effect of parental intervention in the motor development of infants. This is a case series, longitudinal, and interventional study, with 100 infants at risk, aged 0-18 months. Motor development of infants was assessed by the Alberta Infant Motor Scale, and the parents received information about positioning and exercises depending on the child's motor score. Risk factors were not related to infants' motor development. However, these risk factors were related to gestational age, which was related to motor development. After parental early intervention, the sample frequency increased from 45% to 69% in the group of children with normal motor development. Frequency was reduced from 55% to 31% in the group with delayed development. Prenatal and/or perinatal risk factors can cause prematurity, and consequently, delays in children's motor development. For these infants, early intervention protocols with parental education are effective to stimulate a normal motor development of children at risk in followup in outpatient clinics. 16RESUMEN | Por intermedio de actividades parentales, la intervención precoz en el desarrollo favorece logros cognitivos, físicos, sociales y emocionales a los bebés, factores determinantes para la salud infantil. Pero son pocos los estudios sobre la intervención precoz con actividades parentales. Así en este estudio se propone analizar los resultados de la intervención parental precoz para el desarrollo motor de lactantes en ambulatorio de una maternidad. Estudio de tipo serie de casos, longitudinal e intervencionista, del cual participaron cien lactantes, entre 0 y 18 meses de edad, provenientes del ambulatorio de la maternidad. Se evaluó el desarrollo motor de los lactantes por intermedio de la escala Alberta. Dependiendo del retraso motor observado en los bebés, se hicieron recomendaciones a los padres. No se encontró relaciones entre los factores de riesgo y el desarrollo motor. Sin embargo, estos factores presentaron relación con la edad gestacional, que se relacionó, a su vez, con el desarrollo motor. Tras la intervención precoz parental, la frecuencia del muestreo aumentó del 45% al 69% en el grupo de bebés con desarrollo motor normal. El grupo con retraso en el desarrollo sufrió una disminución en la frecuencia de la muestra del 55% al 31%. Los factores de riesgo prenatal y/o perinatal pueden implicar precocidad y, por consiguiente, retraso en el desarrollo motor infantil. Para lactantes en ambulatorios, estos protocolos de intervención precoz con actividades parentales son eficaces para promocionar su desarrollo motor normal.Palabras clave |

“…This justifies taking the precaution of assessing child development in a systematic manner, utilizing validated instruments and putting emphasis on motor development during the first years of life. 1,2 It is recommended that corrected ages should be used when evaluating the development of premature infants in order not to underestimate their capacities. Notwithstanding, chronological age should also be taken into consideration because the development of some premature infants can be overestimated using corrected age.…”
