Además, utilizamos seis alambres de plomo para calibrar el sistema y garantizar una precisión de 2 mm. Fue verificado que el uso de cuatro cámaras de video es más apropiado para garantizar la visibilidad de dos marcadores simultáneos, permitiendo la reconstrucción tridimensional del movimiento. El sistema Dvideow 6.3 fue utilizado para el análisis de las imágenes. El experimento tiene una duración de dos minutos, subdivididos en dos condiciones: entrenamiento y observación. Para la adecuación del método, cuatro lactantes fueron filmados, longitudinalmente, en las edades de uno a seis meses en la posición supina. Portanto, concluímos que a utilização do sistema Dvideow para realizar a análise cinemática dos chutes de lactentes mostrou-se adequada e viável, uma vez que esse sistema é acessível, de baixo custo e de fácil utilização para os pesquisadores em geral.Descritores | lactente extremidade inferior desenvolvimento infantil biomecânica.RESUMEN | Los objetivos de este estudio fueron describir el método utilizado para el análisis cinemático de los movimientos de pataleo en lactantes y probar su factibilidad de uso, empleando el sistema Dvideow. Além disso, utilizamos 6 fios de prumo para calibrar o sistema e garantir uma precisão de 2 mm. Foi verificado que o uso de quatro câmeras de vídeo é mais apropriado para garantir a visibilidade de dois marcadores, simultaneamente, permitindo a reconstrução tridimensional do movimento. O sistema Dvideow 6.3 foi utilizado para análise das imagens. O experimento teve a duração de dois minutos, subdivididos em duas condições: treinamento e observação. Para adequação do método, quatro lactentes foram filmados, longitudinalmente, nas idades de um a seis meses na posição supina. It was concluded that the use of the Dvideow system to perform kinematic analysis of the kicking movement in infants proved to be appropriate and feasible, since this system is accessible, of low cost and easy to be used for researchers in general.Keywords | infant lower extremity child development biomechanics.RESUMO | Os objetivos deste estudo foram descrever o mé-todo utilizado para a análise cinemática dos movimentos de chutes em lactentes e testar sua viabilidade de uso, empregando o sistema Dvideow. Moreover, 6 plumb lines were used to calibrate the system and ensure an accuracy of 2 mm. It was verified that the use of four video cameras was more appropriate for the visibility of two markers simultaneously, allowing 3D reconstruction of motion. The Dvideow system 6.3 for image analysis was used. The experiment lasted two minutes, divided into two conditions: training and observation. To adjust the method, four infants were longitudinally videotaped at ages from one to six months in the supine position. | The aims of this study were to describe the method used for the kinematic analysis of kicking movements in infants and test its feasibility of use, using the Dvideow system. Conclusions Among the positions evaluated, the prone position without inclination of the supporting surface was more appropriate for weight discharge in the upper limbs, favoring the development of postural control of the child. The inclination of the supporting surface did not influence the alignment of the head and upper limbs. In the third month of age compared with the first, increased head alignment and decreased upper limb alignment were found in both groups. There was no difference in the upper limbs’ alignment between the group with TMD and the group with AMD. Results Children with TMD had higher head alignment. Kinematic analysis was conducted to evaluate the alignment angles of the head and upper limbs. The children were placed in the prone position with three angles of the support surface (0°, 25° and 45°). Methods The study included 29 children aged between one and three months divided according to the Alberta Infant Motor Scale (AIMS) into groups with TMD (n = 18) and AMD (n = 11). Objective To investigate whether age and inclination of the supporting surface in the prone position influence the alignment of the head and upper limbs of children with typical motor development (TMD) and atypical motor development (AMD). However, there is still no consensus regarding the best position to achieve this the evidence suggests that it is prone. Introduction It is expected that a child will acquire control of posture (CP) of the head and upper limbs in a gradual, sequential and organized way.
