As a complementary tool, an autoregressive modelling technique was used allowing us to establish after each single ride considerable decreases in the frequency of the feet adjustments, which represent the control variable of the postural system in sagittal plane. These changes reflect diminished ankle joints stiffness resulting from a single session, and are supposedly a basic reason for substantial progress of the patients. The autoregressive approach proved to be a powerful method, which corroborates and reinforces stabilographic investigations. The findings confirm that the therapy led to a noteworthy improvement in the postural performance of the CP children in sagittal as well in frontal planes.
