Method for the kinematic analysis of kicking movement in infants

Abstract

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. To adjust the method, four infants were longitudinally videotaped at ages from one to six months in the supine position. The experiment lasted two minutes, divided into two conditions: training and observation. The Dvideow system 6.3 for image analysis was used. 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. Moreover, 6 plumb lines were used to calibrate the system and ensure an accuracy of 2 mm. 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.
