“…Although, at first glance, the observed results demonstrate numerous possibilities of responses in these younger infants, the researchers affirm that they bring valuable sensory-motor experience which is fundamental to support and drive change in development. Even young infants have shown small sporadic changes in perception and action over a short time scale, as in the study by Guimarães & Tudella 26 , which indicated that even shortterm practice may increase an infant's intrinsic motivation to reach the object, demonstrating their sensory-motor capacity to perceive and respond to the demands of the task. In this way, it might have been necessary to practice for a longer time scale for these small changes to reflect on behavioral stability, becoming more consistent.…”

Introduction: Little is known about the real impact the practice of manipulating objects on the development of infants perception-action and it is assumed that this newly acquired knowledge is useful for planning future actions. Objective: To analyse the effects of controlled practice on the tasks of reaching and transporting objects in 10-month-old infants when the weight of the object was changed. Methods: Sixteen infants were divided into two groups: heavy/ light group (HLG) and light/heavy group (LHG). The task consisted in reaching, grasping, and lifting a lighter or heavier bar 9 times. On the tenth trial, the object weight was switched to the heavier or lighter weight object (whichever was opposite to the object weight experienced in the first 9 trials) to assess whether infants had learned and adapted their object-directed movement strength to the initial weight condition practiced during the first 9 trials. Results: No significant differences were found when comparing the reaching and lifting phases within groups (LHG, P = 0.06 and HLG, p = 0.41). However, group comparisons revealed that HLG infants presented increased velocity peak (p = 0.01) during the trials. Conclusion: The reaching and object lifting trials of the infants throughout the attempts were very variable, indicating that, possibly, at 10 months of age, infants present transitions from one organizational state to another. However, it is necessary to carry out more detailed investigations on reaching and lifting actions of objects to understand the processes involved in these transition periods.

“…Most of the studies started the training before or within a few days after reaching onset, thus minimizing the influence of spontaneous practice as a confounding factor that could bias the outcomes. On the other hand, some studies did not report on the infants' skill level [21][22][23]27 , which makes it more difficult to conclude on how much the training improved reaching regardless of the influence of spontaneous practice. Future studies must be attentive to this issue.…”

Introduction: Researchers have widely investigated how interventions by means of training can improve manual behaviors in infants. However, no systematic review has been found on this topic. Objective: To analyze the quality of scientific evidence considering the methodological quality and level of evidence by type of study in research on training of object-directed manual behaviors in infants in the first 18 months of life. Methods: National Library of Medicine (PubMed/MEDLINE), Latin American and Caribbean Health Sciences (LILACS), Virtual Health Library (BIREME/BVS), Science Direct, SciELO, and Physiotherapy Evidence Database (PEDro) databases were used. Only clinical trials that assessed the benefits of manual object-directed training in infants and were published up to February 2018, in English, were included. The Cochrane Collaboration Model was adapted to extract bibliographical data from the articles and their methodological quality was assessed using the PEDro scale and the Oxford Centre for Evidence-Based Medicine’s Levels of Evidence. Results: Twenty one clinical trials were included. Studies investigated typically developing full-term infants, preterm infants, and infants at risk for autism spectrum disorders. Trainings were administered to infants by means of “sticky mittens” paradigm, task-specific practice, or contingency reinforcement. Most of the studies presented fair or poor methodological quality. Only studies that used task-specific active practice presented high methodological quality. Conclusions: The results indicate there is high quality evidence that task-specific training improves object-directed manual behaviors in typically developing infants and preterm infants in the first 2-4 months of life. Studies addressing infants with established diagnoses of developmental dysfunction are lacking.

“…Thus, when compared to full-term children, the exploitation of the environment becomes more difficult for the preterm infant 4,5 . In view of this; the increase in the number of premature infants is an issue that requires caution and monitoring of their development and quality of life 6,7,8 .…”

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 difference between the mean general motor age (37.6 ± 7.40) months and the mean chronological age (43.2 ± 2.59) months, indicating delayed motor development. Conclusion:It was observed the absence of linearity of the variables, indicating delay in the motor development, thus justifying the necessity and importance of the longitudinal monitoring of this population for early detection and intervention.Suggested citation: de Sousa GVG, Lage JB, Guimarães EL. Motor development analysis of three-year-old children born preterm through the Motor Development Scale -Case Report. Open acessWhat is the purpose of this study? It is a paper from the Physiotherapy graduation process, derived from the doctoral research "Effect of specific training on manual reaching ability in preterm infants". During the initial research, the infants were evaluated and those who presented some indication of development delay due to prematurity and low birth weight were referred for early intervention. What researchers did and found?After three years of the initial evaluation, the researchers verified the overall motor development of this population. Therefore, the children who attended and whose parents agreed to participate in the present study were re-evaluated through the Motor Development Scale (MDS). It was observed that the three-year-old children still had developmental delays, especially in spatial and temporal organization, and according to the mothers' reports, they had been submitted to early stimulation with physical therapy until the independent gait ability. However, they could not say how long the children were followed, thus justifying the need for longitudinal and multidisciplinary follow-up, even after gait acquisition. What do these findings mean?Such findings are relevant to professionals, parents, caregivers and family members' awareness of the need for early multidisciplinary intervention programs with longitudinal follow-up of preterm and underweight children.
