This study sought to highlight the balance control process during gait in
children with cerebral palsy (CP) by analyzing the different strategies used in
order to generate forward motion while maintaining balance. Data were collected
using a motion analysis system in order to provide a clinical gait analysis for
16 children with CP and 16 children with typical development. Significant
differences between the two groups are observed in terms of kinetic data of the
propulsive forces of the center of mass (COM) and of the center of pressure (COP)
dynamic trajectory and for locomotor parameters. The imbalance generated by
divergent trajectories of COM and COP produce the propulsive forces responsible
for human gait initiation. Moreover, we observe in children with CP an "en bloc"
postural strategy resulting in increasing divergence between trajectories of
COM-COP. This particular strategy of the children with CP is characterized by a
greater time duration between the moment of COM-COP trajectory divergence and the
moment where the forward propulsive forces became apparent.
