Interfacing computerized biomechanical analysis in monitoring the motor development of children

This research investigated the effectiveness of using kinematic analysis to monitor the motor development of children on three fundamental movement patterns. 12 children with specific motor delays were filmed before and after participation in the 2-hr. per week, 7-wk. program. The film was analyzed (60 frames per second) using a 2-dimensional analysis system. There were no significant differences when a Wilcoxon matched pairs signed-ranks test was applied to the galloping and skipping center of gravity and linear velocities of the ball data. Timing of the peak linear velocities of the upper body showed subjects increasingly exhibited the more advanced, sequential pattern and no longer exhibited the less advanced simultaneous pattern after the program. It was concluded the changes in timing were evidence of improvements in coordination.
