title: Corporal oscillation during static biped posture in children with cerebral palsy.
abstract: This previous study was performed to compare the antero-posterior and medium-lateral displacements and the speed of displacement of the COP of healthy children and compare them to children with cerebral palsy type spastic diparesy. This study had the participation of 10 healthy children (6 girls and 4 boys), between 5 and 10 (7,6 +/- 2,1) years old, and other 10 children, all diagnosed as CP type spastic diparesy, (5 girls and 5 boys), between 5 e 10 (7,3 +/- 1,8) years old. To collect the data, we used the antero-posterior (AP) e medium-lateral (ML) displacements of the COP The parameters were compared by the variance analysis (ANOVA), and the post hoc test was Tukey's HSD. The level of significance adopted was p < 0,05. After the collect of data and statistical analysis, it was observed that the medium amplitude of the AP and ML displacements was higher in CP children, related to the healthy children: AP-F(I,18)= 1,66 (p = 0,002), ML-F1,18)= 3,36 (p = 0,002). As the amplitude, the speed of the displacements was also different among the children. The speed of the displacements, AP and ML was higher in CP children - F(1,36) = 0,009 (p = 0,00). There were no differences between the speed of AP and ML displacements, neither in the healthy children, nor in CP ones - F(1,36)= 0,00 (p = 0,87). The sensorial deficit found in CP children is an important issue in the increase of the amplitude and speed of displacement of the COP.
