Sl. Jackson et J. Healey, Interfacing computerized biomechanical analysis in monitoring the motor development of children, PERC MOT SK, 91(3), 2000, pp. 999-1008
This research investigated the effectiveness of using kinematic analysis to
monitor the motor development of children on three fundamental movement pa
tterns. 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 wa
s applied to the galloping and skipping center of gravity and linear veloci
ties of the ball data. Timing of the peak linear velocities of the upper bo
dy showed subjects increasingly exhibited the more advanced, sequential pat
tern and no longer exhibited the less advanced simultaneous pattern after t
he program. It was concluded the changes in timing were evidence of improve
ments in coordination.
